"I am a newcomer, but I don't want to hire a guide."


There is an increasing number of tourists who want to explore new places on their own while the existing services are not engaging and friendly enough.


I design a VUI system - Travi to help my targeted users to provide instant help or suggestion based on whatever they need.

Wizard of Oz Test

In order to see how Travi works, I conducted a user test designed for Conversation Design called Wizard of Oz Test. I made a paper prototype for my product (I decided to make it as a smartwatch) and hide in someplace, using a computer with pre-record audio to do the test while using a camera to see user's reaction.


More scenes:what about begin from indoor places? What about if the users don’t know what to do?

More hints: This is the end of info; This is the end of the tour. This is just for you…

When just said “Hey Travi” what should the System say?


I did do some tuning work while I didn't take all the advice. I added some hints at the beginning when the user uses Travi for the first time. Plus, there is some principle called "just in time" in conversation design, which means don't give users too much information besides what they need. So, I added some hints once the user arrives at that place.

Happy Path Video/Audio

What Have I learned

There are different levels of VUI: some relay a lot on GUI; some relay less; some doesn't need any visual support at all. Finding a good user case is crucial in conversation design. Also, we have to be very careful about the amount of information in VUI. By launching this product, I want to empower every tourist to explore the place and enjoy the moment by themselves.
