The other implementation features of Google Maps navigation and phone calls was straightforward. The main implementation problem involved the swiping of tiles and generally how users picked two restaurants to compare. We concluded that our application successfully conveyed the correct message to users through the implementation, and the application met our satisfaction.
Evaluation
For our user test, it was important that we did not give a demo before the test. The greatest learnability problem in our application is figuring out that tiles can be swiped and pinned. If we showed a demo, this behavior would be immediately apparent, and the test would not be indicative of an actual user scenario.
Our test population was chosen out of a group of poor college students that typically search for new restaurants on a regular basis. We chose three participants, and gave them the same directions: Compare the Hana Sushi and Full Moon restaurants menus, and then choose Hana Sushi to see more information. The last direction was to call Hana Sushi (hang up immediately) and then get walking directions to its location.
In our first computer prototype, the users had trouble determining how to get information from new restaurants. In the final implementation, we showed a loading screen that showed swiping animation in the background. All three users in our test knew how to swipe restaurants away after watching the loading screen. One user did not know that pinning two restaurants brought them to a second page, but the other two users had the right idea. All three users were able to select Hana Sushi and call them. All three were also able to get navigation directions.
In conclusion, the user testing went very well and really showed the necessity for the loading screen animation. We might show two tiles being pinned in the animation and a page transition in order to show users how to use the app. It would basically be an automatic demo in the loading screen, and that is probably the next step in the implementation. User testing was very beneficial to us during this project's implementation.
