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 icons
Apps living in silos of their
own are no longer tolerable
Jumping from one app to
another is so not cool
All 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

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)
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)
Understanding Conversational Interfaces
1. Rule-based implementation
2. Machine learning-based

Jerry: XiaoIce, will it rain tomorrow?
XiaoIce: Tomorrow the weather in Beijing will be nice with a maximum high of 25*C. No rain to get you soaked.
Jerry: How about the day after tomorrow?

Jerry: What about Seattle?
XiaoIce: Yes sir, I’ve got the answer. The day after tomorrow, Seattle will be cloudy with a max high of 30*C. Perfect for going
outside.
Jerry: “Finding Mr. Right” is a great movie. What do you think XiaoIce?
XiaoIce: Oh, romantic comedies are my favorite! It stars Tang Wei, who finds love in Seattle. You should watch it.
Jerry: Do you like Tang Wei?
XiaoIce:
XiaoIce: A goddess! She stole my heart… and then went off and married!
Tom: To who?
XiaoIce: Haven’t you heard?
XiaoIce: Tang Wei is engaged to famous Korean director Kim Tae Yong.

“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?
