Chat is eating everything else for breakfast!

The most important question: WHY?It’s an exciting time to be alive… we’re witnessing a paradigm shift again

Our device screens are overflowing with app

iconsApps living in silos of

their own are no longer tolerable

Jumping from one app to another is so not

coolAll apps are not

born equal

Consolidation

Invisible Apps

“Just enough UI or no UI is the new

UI”

App / Notification / OS

Alienation: We’re beginning to miss human(-like)

interactions

Time spent in messaging apps now far exceeds

that in social media apps

Human Evolution: Learnt behaviour Innate behaviour

What

Also known as “Artificial Conversational Entity”, its

designed to enable users to accomplish complex tasks through

natural dialogue

Understanding Conversational Interfaces

When

1. … instantly reachable, almost hiding in plain sight – no need to be downloaded, they live on servers, not a user’s device. This means using bots should provide a smoother experience for the user as switching between bots doesn’t involve tapping on another app.

2. … a trusted relationship helps (bot = my friend)3. … the objective is to accomplish a singular task but too many options available

(ask directly)4. … data entry is easy but processing and analysis is burdensome (offload analysis

to server)5. … the traditional screen interface is too complicated or small (GUI is not always

the answer)6. … a request does not have to be completed immediately (asynchronous + small

talk)7. … context switching if required needs to be easy and not jarring (bot to human

hand-off)8. … user is interacting with multiple byte-sized, micro- and in-the-moment

experiences (switching contexts not apps)9. … user does not enjoy browsing or deal with subjectivity (most shopaholics may

hate bots)

Understanding Conversational Interfaces

How

1.Rich text-based interfaces (limited to text and emoji’s only)

2.Text interspersed with GUIs (most commonly adopted by known bots)

3.Voice-based interfaces (think virtual assistants)

What all the fuss about C-UI’s personality?

“People don’t want something truly new, they want the familiar done differently”California Role Rule (Nir Eyal)

• We moved from CLI (think MS-DOS) to GUI (MacOS and Windows)• GUI used real-life objects as interfaces: Recycle Bin, Magnifying

Glass etc.• Glass-look UI pioneered by Apple through iMac and iPhone

Are people you interact with dry and boring? Then why keep chat-bots so?

Why should you care about your bot’s personality?
