Touchscreens may be popular both in science fiction and real life as the symbol of next-gen technology, but an innovation called Skinput suggests the true interface of the future might be us.Microsoft and Carnegie Mellon University unveiled Skinput recently, showing how it can turn your own body into a touchscreen interface.INTRODUCTION:

3

Microsoft is working on a new flesh-control input technology called skinput. But, its not what youre (probably) thinking. While it might be possible to one day adapt this tech to more, shall we say, erotic applications, the first iteration of the skinput technology focuses on using the flesh as input controls for mobile devices. The implication here is that everything from smartphones to music players to computers could be controlled with a simple double-click on your forearm

A new flesh-control input technology called skinput. A revolutionary new technology created by Microsoft and Carnegie Mellon University uses 'body acoustics' to turn your skin into an interactive touchscreen called Skinput, the unusual interface enables you to use the surface of your skin to control your gadgetsWhat is Skinput?

We transmit data everyday through a host of media: wires,cables, the air, etc. But did you ever think we might one day be able to transmit data through our arms? That too atbroadbandspeeds?Human skin is apparently a very energy-efficient conduit for transmitting dataSouth Korean researchers placed electrodes about 12 inches (30 centimeters) apart on a persons arm, and found that the low-frequency electromagnetic waves travel easily through the skin without any outside interferenceHow Skin works as a touch?

Transmission of electromagnetic waves through skin

mechanical vibrations are generated in body when we tap our finger on body. these are used as signals which are collected by an armband which works with an array of sensorsPrinciple:

How it works?Fantastic advancement in the field of electronic gadgets.It is able to convert a human arm into touch screen interface.Consists of following:

1.Pico projector : projects display list 2.Acoustic detector : this is present in armband then calculates which part of display you wanted to activate 3.armband

10

A Pico projector can project a menu, keyboard, or buttons onto users' skin to help them navigate their 'arm touchscreen,' although the display is optional--asGizmodopoints out, the 'body acoustics' technology allows the Skinput system to recognize 'which part of your body you've tapped, based on the sound that's made on either the skin, muscle or skeleton.'Pico projector:

The armband attached to the bicep area contains five piezoelectric cantilevers. Each responds to certain sound frequency ranges.. A bulky armband array is attached to the bicep area to pick up waves propagating through arm tissues after taps on the fingertips or elsewhere on the arm, up to the area above the elbow.

12

Before using our arm ..some requirements are to be metPandoras box revealed: variation in bone density , size , mass,filtering effects from soft tissues and joints mean different skin locations are acoustically different. waves change depending on where you tap as they run through bone , soft tissues

13

Special software analyzes the waves and uses the information to work out exactly where you touched just as you were tapping on touch screen next, their software matches sound frequencies to specific skin locations , allowing the system to determine which skin button the user pressed.This also uses wireless technology like bluetooth to transmit the commands to device being controlled(ipod /phone /com)

1.No need to interact with gadget directly2.Dont have to worry about keypad3.People with larger fingers get trouble in neighbouring tiny buttonsAnd keyboards on mobile phones with skinput that problem disappearsAdvantages:

15

BIG band that looks very easy to put on. Many people would not wear a very big band around their arm for the day just to have this product.Skinput does not answer the incoming calls, you still have to reach in your pocket, find your phone and answer it.Also, not everybody can use this product, the elderly for example have a hard time adapting to technology as it Is.Individuals with visible disabilities such as amputated arms or the blind cannot use this product.. Disadvantages:

16

We have presented our approach to appropriating the human body as an input surface. We have described a novel, wearable bio-acoustic sensing array that we built into an armband in order to detect and localize finger taps on the forearm and hand. Results from this have shown that our system performs very well for a series of gestures, even when the body is in motionThough it has certain disadvantages at present ,it can be modified in future for better use.Conclusion:
