Abstract

In this thesis, we develop and implement mobile Healthcare system on the iPhone and Apple

watch to help seniors to manage their health life. MyHealth which is the application name will

remind the user to take their medicine and record the dosage they took. The Application will

measure the heart rate and when the heart rate became above or under a certain level it will

notify the user’s emergency contact. The notification will be a call, SMS and email, the user will

choose the contact when he using the App. Also, it will remind the user to move and exercise

and it will track the user movement. MyHealth will record the data that collected from the heart

rate measurement and send these data to the user physician weekly to monitor their health while

they are away from hospital.

Chapter 1 Introduction

In the contemporary world, a lot of technological inventions are being developed at fast rate. In

this regard, many businesses are using the technological development to improve their functions

and operations for achieving the required levels of output. Many people can afford to manage

their social and private lives using different technologies like personal digital assistants among

others [Diva2013]. Technology has improved the manner in which information is developed and

shared [ONei2013]. The development of the Smartphone seems to have had a big impact in the

social and economic dimensions of life. With these smart devices, people can manage their

emails and social networking from their convenience. Developers have focused on creating many

essential functions that people often seek. Developers have not stopped at that, thousands of

mobile applications are being to influence business practices, governance, and investment. It is

important to point out that the beneficiaries of these technological have not been businesses

alone, the healthcare industry is also benefiting heavily from technology.

The healthcare is an urgent society problem. With the increase of elderly population, the

demand on senior healthcare has been increased. The GreatCall Health agency reported a

statistic shows that the mobile healthcare industry will be projected a 26-billion-dollar industry

by 2017. There are a lot of health and Fitness applications that have been downloaded daily by

users all over the world. To be able to manage your health from your phone is a promising idea.

Especially we would like to remind senior people their medication and to assist them to contact

their health providers easily.

When people become old, the level of activity tends to reduce considerably and need

more support from other people. Additionally, [Yoo2013] explains that many elderly people tend

to have health issues that need constant attention from medical practitioners. When these elderly

people visit hospitals and are given medicines, they often forget taking them as required. This

observation is common among many elderly people, who in most instances, prefer to rest for

long hours with little physical activities. When these people do not have someone to monitor

their progress, they can succumb to the old-age health complications. Perhaps this may explain

why many people prefer having their elderly family members taken to nursing homes where they

can be taken care of by people specially trained for that.

According to [ONei2013], taking the elderly to nursing homes is not always a better

option, because most seniors like to be taken care of by their own relatives. In this regard, taking

them to the nursing homes makes them feel lonely and stressed up, something that can aggravate

their health conditions. This understanding has sparked the need of having special ways in

which, these elderly people can be monitored by doctors from the comfort of their homes without

necessarily having aides. Many developers have been active in the research and development of

various applications that can be used to achieve this important goal [Ozda2012].

1.1 Aim

My aim is to implement and evaluate Mobile application that could help seniors to manage their

health life while they are away from hospital. By remind them to take their medicine, measuring

their heart rate and remind them to move and track their movement. Also, to help the physician

to track the health data of their patient while they are away by sending the heart rate data to them

weekly. Also, the physician will know if their patients are taking their medicine as they describe

2

or not. These data will help in many ways, to improve the patient health issue. Also it can be

used in research area if they took the approval from the patient to use their data.

My proposal question was: Can I design an accurate and effective application using the

HealthKit with the Apple Watch?

Since the correctness and timely of health information report by the mobile device is critical to

the user’s health. It is critical that the design of mobile healthcare app with Apple Watch be

conducted with extra care, more rigorous process, and thorough experiments. The difficulties are

further complicated by the fact that there are few resources for the watch. The challenge here is

to use the Apple Watch sensors in my health application and to send these data back to the

iPhone. Also, notifying the emergency contact based on the measured health information in real

time is still a new idea. Related questions include who to notify and in what order, and what are

the information to reveal. In this document I will discuss in details my work to achieve this aim.

Chapter 2 Background

Currently, hundreds of applications have been developed with the aim of managing some

important tasks and resources like time and information, access and maintenance of health

records, consulting and communications, training, education and decision-making among many

others. However those are not the focus of the proposed research.

Different companies are currently researching on how they can tap into the business

opportunity that exists in the healthcare industry. Healthcare practitioners acknowledge the fact

that the use of mobile devices has been instrumental in improving the health of patients. The

mobile apps also help doctors in their clinical decision-making.

Apple has in the recent past made huge strides in this sector. The development of the

Apple watch has been regarded as one of the best innovation in healthcare [Guar2015].

2.1 The Apple watch

The Apple Watch has been described as the big thing in health care [Guar2015], having

features that bring the doctor virtually at the patient’s home, especially for the seniors in the

society. The Apple Watch comes with an accelerator and heart rate monitor, which are beneficial

in calculating the level of general fitness for the patient or person wearing it. The device has the

ability to augment the particular information by linking with the iPhone. Using Wi-Fi networks

and GPS satellites, the device can also gather information that is used in determining its specific

location at any point and any place.

The data from the Apple watch are provided by the two built-in sensors, accelerators and

infra ray sensor. One reports the movement of the body. The other reports the expansion or

4

shrinkage of blood vessel. The data collected by the accelerator sensor will then used by the

apps to derive one’s workout and activities. The data collected by the infra ray sensor will be

used by the app to decide the heart rate. This device enables the user of the watch to track the

intensity of jogging and gym activities as well as walking and other exercises being done in the

neighborhood. On the other hand, the sensor devices are quite passive. It tracks light exercise

session like movements that the user makes during the day. These exercises may have been done

within a minute or 12 hours. The activity and workout apps work alongside the Healthkit

framework and health app, which have been announced by the company as having been

incorporated in its iOS 8 [Guar2015].

Apple develops the HealthKit to enable sharing data between the new health app and

between the apps that provide health and fitness. Also, by using the HealthKit any app that

provides health and fitness services can share date among each other. Managing the data from

different sources and merging the data from all sources based on the user choice is the HealthKit

design functionality. Apps who are using the HealthKit are able to access the data from any

source and do their own changes or merging’s on them. The user of the main health app can

choose which data to share because he is sure that his health information is safe and secure in the

Apple health database. The HealthKit also provides storage service that synchronizes the local

health data on apple watch with those in iPhone and iCloud. [Appledeveloper].

Another important feature of the Apple Watch is that it can easily monitor sleep patterns

and heart rates in the most convenient way [Kise2011]. Other essential tests that can be done

5

including blood and urine where data can be entered by the user and can be managed through the

kits and the resulting information linked to the iPhone. The phone can perform an analysis of the

data and store it for future use, or the data can be sent to the doctor for further treatment.

The owner of the iPhone can have a highly comprehensive profile relating to their health.

In this regard, he can determine his lifestyle patters and activities that affect his life on daily

basis. This understanding is important in making decisions that can be used to improve the health

in different ways [Appledeveloper].. By developing mobile apps with Apple Watch, we hope to

contribute to the developer community and enable others to develop app in this area. The current

idea is to use the HealthKit to measure and record the heart rate and notify the elderly emergency

contact in case of emergency.

2.2 History

Using mobile technology in the health area is not a new idea. The need for using mobile

application has been increased with the increase of the cost of health insurance and staying in

hospitals and nursery. A lot of studies focused on using mobile health application un

different health situation. For monitoring patient health life, diagnose health issues and for

research and study areas. Some of these studies has a good results and some of them did not

achieve what they looking for. The cost of time and the critical of health experiments extent

of the result of using health application. In my search I tried to focus on some of these

experiments that made a print in mobile Healthcare area. The first study was called "The use

of personal digital assistants in clinical decision making by health care professionals: a

systematic review." Health informatics journal. In this study they made an exterminate in the

emergency room at hospital they gave the patient a smart phone with an application to page

his doctor in case of pain. They wanted to record how fast the doctor response and Did the

6

patient use the application or not. Over all result was some time the patient does not have the

time or energy to use the application in case of pain so I thought how can we do that

automatically. in case of emergency we should let the application sense and call for help.

The second paper that I get used of it is called “Apple Watch has designs on health industry –

but is it good for doctors? “this paper discusses in detail how Apple watch sensors designed

and how the watch is related to Health application. The conclusion of the paper was

promising that the Apple watch future will make a difference in mobile healthcare industry.

That’s why I choose my application to use the Apple watch even though it’s a new feature

and it’s hard to fine resources to implement but maybe this thesis will be the base for future

studies that may make a difference in the mobile health area.

“25 ways to use your smartphone. Physicians share their favorite uses and apps.” This paper

shows how smartphone application helped to improve health in the society. They made the

users more aware of the disease and their effects on the patents. They gave the patient the

knowledge about the medicine that they use and what their side effect. The mobile health

application gave the user the aware of infection disease that are spread on a specific time and

how can they avoid it. It helped the physician to keep track of their patient health history. It

also discussed how the application used on the computers on clinics made it easier to know

what the patient history but this area is not my thesis interest. So, as a result of this paper the

mobile healthcare application can make a difference we can get a useful result and this is my

attention from my application.

In this paper “Applying surgical apps: Smartphone and tablet apps prove useful in clinical

practice”. They made a study on senior people in a nursery they train them to use some

application and they record the result of using these application. They said that these

7

application make the patient more aware of their health issues and they became more careful

with their health. Also, they discuss the use of Artificial intelligent inventions on Operation

room and this is will be the future if the developers invest on it.

While I am reading in mobile health industry area I found this research paper that called

“"The smartphone in medicine: a review of current and potential use among physicians and

students." In this paper they made 60 study on the impact of using smartphones on health

area. How can we used of the phone feature such as Wi-Fi, GPS to make application that can

help users to improve their health life away from hospital.

“ The meaning of information technology (IT) mobile devices to me, the infectious disease

physician." Infection & chemotherapy” in this paper they studied why we should focus on

seniors because they have more health issues and the population of elderly people in increase

yearly. So, to produce application that can help them improving their health life is sparkle idea.

That’s why I wanted to make seniors my target of my MyHealth application.

Chapter 3 Design

The basic functions of MyHealth Application are:

1. The user should Add their medicine by: name, start Date, End Date.

2. The application will notify the user when the time is due.

3. The Watch will read the heart rate of the user each 10 minutes.

4. If the heart rate above or below the normal level it will notify his emergency contacts.

5. The Application will remind the user to move and do some activity and track his

movement.

6. The application will collect the heart rate data and send it to the user physician weekly.

figure1.1: System overview Diagram.

3.1 System Architecture:

To implement MyHealth application we need:

Mac Operating system with Xcode installed on it in my application I used xcode 7.3

Swift 2.0 is the program language that I used to implement my application

We need to use AppGroup in the xcode file

HealthKit is the major component of MyHealth xcode project.

3.2 iOS Development:

In the mobile platform, a large market share is held by the iPhone; this being

the reason behind interest in learning about iPhone development. The

process of development entails an outline of how to establish the hardware

for the applications. Setting of the software requirements and the final

system requirements is also part of the process. Apple Inc. has made it

easier for people who want to become developers with them. All a person

needs are an account charged $99 annually, a mac computer, Xcode

platform and a coding experience, such as the Swift and Objective-C coding

languages.

3.3 Swift 2.0:

The apple Inc. created a modern programming language called swift. It is

specifically developed to be more precise and flexible than the Objective-

C. Swift has LLVM (Low Level Virtual Machine) compiler framework that

utilizes the objective-C runtime allowing C, C++, Swift code and

Objective-C to run in a single program. The flexibility of Swift is attributed

10

to its capacity to support widespread late binding, dynamic dispatch and

extensible programming. It is also considered safe and can effectively

manage the common programming errors, for example, the syntactic and

the null pointers to prevent occurrence of unwanted results.

Swift 2.0 is an open source programming language with a lot of better

performance than the old versions on error handling API, support

availability checking and it’s feel more natural with enhancement to the

Apple SDK.

3.4 AppGroup:

3.4 AppGroup used to share data between different application or in

different interface at the same application. To use AppGroup you

have to turn on the Appgroup in your application and on the

extension that you want to share data among them. [Tom2014]

11

3.5 Healthkit:

Apple developed Healthkit to enable developer to develop health

and fitness application. By using Healthkit and the customer

approval you can share the health Data on Apple health Database

to your application. You can use these health data , make your

changes and calculation on it, which can make your application a

valuable health source. You can use Healthkit in your application by

turning on the Healthkit icon on xcode that will give a lot of options

in your code.

3.6 MyHealth In my thesis study I implemented a health application on iPhone and Apple watch that has

the name “ MyHealth”. The application will have two interfaces. The user interacts with

each interface differently.

12

Figure 2: User interact with iPhone system.

Figure 2 shows how the User will interact with iPhone interface. The user should use the

iPhone to Add his medicine, Add emergency contacts and deal with the notifications.

13

Figure 3: User interact with Apple Watch interface.

14

Figure 3 shows the User interact with Apple watch interface. It will read the heart rate

and show what is the heart pulse. Also, the notification will show on the watch to remind the user

of his medicine. The user can deal with the notification on the watch.

Figure 4 DFD diagram of heart rate measurement

Figure 4 show the main feature of MyHealth application. To measure the heart rate the

user should wear the watch. The application will send notification to the user that it will measure

the heart rate. In case of the heart rate below or up the normal level the App will send the

notification to his emergency contact. Otherwise it will save the read and repeat the process after

10 minutes.

15

3.7 MyHealth Design Since the target is elderly people in my design I choose it to be simple, direct, easy to use.

When you first run the app it will show the first interface screen.

This is my health main screen when you first run the app it will ask you the approval to user your

health data. If you approve you can use the application easily. As it is shown on the button there

are two tabs. If you click the Reminder button this page will be shown:

16

In this page the user should write his medicine name. The start date and time and the End

date and time for his medicine. The Repeat drop down list it will give you the option to repeat

the reminder notification for a week, month, year.

The contacts button allows the User to choose or enter his emergency contacts. The user

can choose two of his contacts to let the App call them in case of emergency. The user can

choose three of his contacts to text and five contacts to send email to them of his Health data and

in case of emergency.

When the App run on the watch first it will show this message to test that the notification

will be shown when the user chooses First button it will Lunch the heart rate

measurement window.

17

When the App is measuring the heart rate this window will be shown on the watch to record the heart rate of the user. At this time the sensor will be green led that’s

mean the App is measuring the heart rate.

18

Chapter 4 Implementation.

To implement MyHealth Application I used:

Macbook pro with El Capitan Operating System.

Xcode 7.3 platform.

Swift 2.0 programming language.

iPhone 6 simulator.

Apple Watch 38 mm simulator.

In my xcode application I used:

Watchkit as target

Different swift files.

AppGroup.

Healthkit.

Inside the xcode application there are three main files which are:

MyHealth which is for the iPhone filesMyHealthWatch which is for the watch

interface.MyHealthWatchExtension which is for

the result on the Watch.

19

The files under MyHealth folder are:

the first file is FirstViewController.swift

Chapter 5 Lesson Learned and Challenges.

Since I start working on my proposal I faced a lot of bad times that I felt I couldn’t make it

anymore and good times when I achieve one task of my application. I was taking a risk of my

application since Apple announce that Healthkit will be open source five months before I start

working on my application. At the beginning I was working on Xcode 7.2 platform but two

months later Apple release Xcode 7.3 I read a lot about it and the decision was not easy should I

upgrade and risk that my application or nor or should I stay on this version even though it is slow

and hangs a lot. I took my chance and upgrade my Xcode to 7.3 which really made a difference

on the time processing the code. Swift 2.0 is an open source programming language it changes

everyday which some times made it hard to implements. Some times the code has no error and in

the second time you work on the code Xcode does not recognize the definition.

My application idea was to measure the heart rate each 10 minutes with out the user knowing

that the watch is measuring the heart rate but that was impossible. I searched a lot and contact

Apple developer society with my problem to find out that before the watch measurement begins

it should at least send a notification to the user because in real life if we implement application

who do that it will finish the Apple watch battery in minutes. So it is not logical to do. So, there

suppose to be a notification before the heart rate measurement. As my professor Chow suggested

after my proposal that I should use the research kit as an add to my application by searching I

found that the research kit is written in Objective-C so I can’t add it to my application but I tried

to record the heart rate data to the user and when the application send it by email weekly you can

do more that research on these data. You can monitor the heart rate health of the user if the

physician found something unusual on the data maybe he can help prevent bad things to happen.

51

Many times the application did not work as it suppose to be that was frustrating to me. In these

cases, I learned that each problem has a solution if I tried to divide the task to small tasks and

each task individually. That’s will make me focus on each task and search a lot about it.

In summery I can say the lessons I learned working on my application are:

Implementing Mobile Health Application is not easy you have to consider all scenarios

that may happen and in real life you do not want any mistakes cause the result is related

to human lives. I can see why there is a limitation on Mobile health industry specially on

critical areas.

After implementing the application and want to test on actual devices the result may

changes the things that have been worked on simulator may not work as it is on the

devices that’s why you need to consider the changes.

My computer had some problems and I took to be formatted so I was trying to code on

my friend’s lab top and to use Xcode on different computer that will revoke your

developer certificate and you need to renew it and that’s gave me really hard time to find

the solution to this problem. I had to renew my Apple developer account for one year

more.

HealthKit gave you a lot of choices to work with the health data but sometimes there is

limits you can not exceed and if your goal is to do something beyond these limits you

have to search more and be smarter than the Healthkit.

Chapter 6 Future Direction.

IOS development is an extensive process that involves mastery of the tools for the development

that is the WatchKit framework. It is then coupled with WatchKit extensions and WatchKit

application. The developer then needs to build up an understanding of the interface, positioning

and formatting. Also, they need mastery of the actions and outlets as well as the lifecycle for the

interface. Further, they need to know groups, the storyboard, interface objects, how to navigate

and finally to perform a test on the application. A lot of test needs to be performs on the

WatchKit but it is something really important to know and work with.

After implementing MyHealth application I hope that It will made the base for future

enhancements and improvements in this area. I had many ideas for my application that I wish in

the future if I had the time I could implement it or maybe in my PhD studies I can develop that.

One idea for the application as if it is for seniors it is common to have memory problems so, if

each time the medicine reminder notification shows if we can implement a bar code reader to

read the bar code on the medicine that can make sure that he is on his medicines. Second idea, if

we can develop and implement sensor machines that can track the hand and body movements so

in cases that the user need physical therapy that recommend doing some exercises we can track if

the user are doing these exercises on the right way. Doctor Lewis gave me a really interesting

idea he is doing a lot of researches on medical applications he told me that if we can develop and

implement sensor machine to record the ECG the electrocardiogram of the heart which can used

to assess the electrical and muscular functions of the heart. If we record it in a good and correct

way, we can find out the heart attack before it will happen. Managing your health life away from

hospitals is the goal of mobile health application if we can think of the diseases that you have to

53

deal with and taking care of your self while you are doing your daily routine we can find an idea

for each need.

Mobile health development is considering a work in progress. It depends on the patients needs

and demands. That does not mean all these application is successful. To consider the application

is successful it depends on it’s performance when it is needed, on the market demand on it, is it

will be needed on five years or not. That’s what the developer are thinking about before develop

in health application. Nowadays Fitness application prove it is quality and effected on people

lives [Miller2014].

The future direction on mobile health application is the application that gather the information

from the user not the ones that give the user the information. That what Apple did in the

ResearchKit that helps to develop application that gather ingormation and health data from the

user to help in research areas[Miller2014]. So, if we consider this to improve MyHealth

application to record the heart rate measurement data and if we improve it to collect other health

information using other development tools that will take the application to upgraded level. I hope

to be able to work on that on the near future.

Chapter 7 Conclusion.

These days’ people are depending on there smart phone in many ways. To organize their daily

tasks. To navigate to a specific location and to remember what they are suppose to do in a certain

time.

There are a lot of mobile health application these days on iPhone, android that’s aspiring to

achieve their goals to improve the health ad fitness life of the user. The requirements for mobile

health application will change with the change of people health issues. Health insurance expense

and care limitation on hospitals are main reasons for the continues demands on mobile health

application that helps users to adapt to his health issues away from hospitals.

These health application helps to increase the aware of the patient parent and relatives of the

illness that the user may have. In some Autosome cases there is a lot of application that helps the

parents to be more aware of their child needs. There are a lot of exercises that they can do to help

their child to adapt with his environment and improve his situation with the help of these Apps

that gives steps and detailed information for them.

iOS development using Swift 2 is an interesting experience it gives a lot of option that you can

implement but on the other hand Apple made some limitation to the developers that you can not

cross. You have to search, dig more to make the development tools serve your Application goal.

Healthkit gives you the access to the user health data and enable you to implement application

that serve health area. Appgroup made it easier to share data between the iPhone and Apple

watch. You can save data to Appgroup and retrieve these data using the same group name.

Apple watch serve the mobile health application with it’s built in features. Sensors to measure

heart rate and sensors to track the movement. While you are setting on your chair watching your

favorite TV show you can get the result of measuring heart rate as the same as on hospital with

55

only one click on your Apple watch. No doubt that made our life easier and more functional.

Using these features of apple watch on developing mobile health application will achieve a

quantum jump in the field of mobile application development. Instead of developing machines

that has sensors to evaluate and measure your health vitals you can use the Apple watch to save

time implementing and developing with the same result as you want at the end.

Focusing on elderly people is important as their population has been increased. Some of them

alone with no relative to watch them all the time and some away of their relatives. To implement

mobile application with easy of use on its interface will help to manage and control their health

needs without the need of supervision or staying at nursery. Seniors needs health application

more cause when you get older your health life needs more care and attention. That is the reason

of choosing seniors as a target of my thesis study. Because I hope some one will use my study

and improve my application to help our parents, grandparents and our self’s when the time

comes that we need to focus more on our health issues and needs.

At the end my Thesis proposal question was: Can I design an accurate and effective application

using HealthKit with the Apple Watch?

After five months of studying and implementing my application on iPhone and Apple Watch I

can answer Yes I can design Health Application on both devices using HealthKit but to call my

application effective I need years of testing on real people life so as a developer I can say my

application can do what is suppose to do. In the future I can see promising ideas and

improvements.

Chapter 9 Appendix

9.1 Installation and Demo Steps.

Because my application is for test and study only I did not publish it to Apple store yet. To install

MyHealth application you need

Iphone 6 with 9.2 iOS or more

Apple watch

MyHealth xcode with developer account.

When you plug the iPhone paired with Apple watch to the computer open the xcode

application and run the App

On the iPhone and the watch, you will get the Application

This the iPhone main page when you first run the application it will be shown.

59

When the application runs on The watch it will ask you to use Your Health Data The health data that is store on the

Apple Health database.

The application will ask you to send Notification that will be shown on the Watch and iPhone.

60

This will be shown on the iPhone you have to turn on the Heart Rate button and click Allow on the top

right.

The Watch will start to measure your heart rate.

61

In case of emergency when the heart rate above or under the Normal level the application will send a Notification to the user to notify him that his heart doesn’t seem good. When the user press Ok it will start

calling and texting.

62

When the Medicine is overdue the Notification will be shown on both iPhone and watch to remind the user ta

take his medicine.

The User has two options either to remind him in 30 minutes or if he took his medicine he can choose

complete.

63

The notification will show on the watch also so, twice daily there will be notification to remind the user to exercise if he chooses complete the phone will track

his movement and tell if he walks or run.

To make sure that the application is tracking the movement of the user the application when the

user start walking or running will send a notification to him.

64

9.2 Performance:

After testing MyHealth application many times xcode enables you to measure your application

performance from Memory, CPU, Network and Disk usage.

This is the performance of running the application on the actual devices iPhone 6 and Apple

Watch.

65

so, the application is not heavy on the computer its only take 1% of CPU uses some times to 4 %

maximum. It is only needs 1.5 MB of memory used.
