Waited carefully on the loading screen
Picked Flour Cafe correctly
Instead of spinning the design wheel, click the food item and expected it to change
Was confused, but then realised spinning would make it change
Expected the food item to go to the middle when clicked
The tag-tip helped him move to the tags to center
Got the gluten-free filter correct
Passed all the tasks
User 2
Waited appropriately for the loading
Liked the big affordance of the spinner for loading
Got the task for the GPS error correct (we simulated a GPS error here)
Likes the wheel aesthetically as a metaphor
Finds the wheel confusing
Not sure what the center can do (tags have to be dragged here, or should the food item change, or both?)
Liked the ability of filters to adjust food preferences
Passed all the tasks
User 3
Did not understand the general spinning/loading screen
Could not figure out the type of restaurant
Dragged the tags naturally (said was possible without looking at the tool tip)
Was able to remove filter successfully
Not sure about the wheel click, but was certain of the wheel selection because of the provided downarrow
Passed all the tasks
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.
