Prototype Iteration
For our first iteration, we used our riskiest prototype. We felt that the scroll wheel would be a fun feature for users to play with and we liked the fact that it would be relatively novel to our user interface. We also liked the idea of a metaphor to the Lazy Susan on a real dinner table. We knew it was a risk, but we wanted to see whether users would be able to figure it out easily. However, each user during our first iteration told us the same thing: the scroll wheel was confusing. The first said that it was hard to tell that it was a scroll wheel at all, and we figured that was because of the low fidelity of our paper prototype. We tried adding in an arrow at the top of the wheel to indicate that it was meant to scroll. Even though this helped users recognize it, they mentioned that it would be frustrating to use on a tiny cell phone because the border icons would be crowded. We ultimately decided that it wasn’t worth making a higher fidelity (i.e. computer) prototype to see whether users could recognize the scroll wheel feature.

The GPS feature was well received by every user. We did one trial with a user where the GPS “glitched” and the user was forced to enter their restaurant into the keypad. This too was received well. We didn’t feel a need to change the GPS feature from one iteration to the next.
