GR6 - User Testing
Design
We knew from the very beginning that one major challenge for our project was visibility. Without written instructions, it would be very hard for users to discover how to use our applications. Therefore, as we iterated our design, we attempted to add more and more appropriate affordances. Below, we describe the evolution of a few key features.
Entire stack selection
Prototype: double click
Final: click inside green circle that appears on stack
We originally thought that double clicking to select the entire stack would be a very useful feature for efficiency. However after the paper prototype and heuristic evaluation, we received criticism that this was not obvious and inconsistent functionality. Therefore, we decided to change our approach to focus on making this action more visible. Users now can select the entire stack by clicking on the green circle that appears on the stack. An alternative design we considered was adding a card fold tab to the stop of the stack (analogous to a page fold tab found in e-books).
