iPod touch - iQuiz

The Design Problem
For our HCI Design I course, our team designed a multiple choice quiz application within the constraints of the iPod touch.

Our Approach
We began our process by investigating mobile computing learning environments to familiarize ourselves with the design space and to learn how digital devices are being used by the mobile community. Our findings and our observations in market demographics, guided the creation of the personas and multiple context-based activities.

Our team needed to design a way of delivering information that would not impact our users personal goals. Also, determine the best way to provide intuitive feedback. Based on our informed design problem and our experiences with the iPod touch, several concepts and visual narratives were produced, leading to a low-fidelity prototype. We evaluated the initial prototype by conducting usability testing. The results revealed how the UI was inconsistent with Apple Human Interface Guidelines and how the screen-scroll behavior conflicted with the drag-and-drop interaction. These and several other problems were addressed by another design iteration.

Our Solution
Our design used the existing iPod touch selection/unselection model. One tap on the answer to select and highlight and a second tap to unselect and unhighlight. Once the answer was submitted, feedback was provided back to the user whether the answer choices were correct or incorrect. For viewing answer selections with long answers and pictures, the existing trackpad gesture convention featured on Apple laptops, the two-finger scroll, was integrated into the design.
