Phase Two - Tree Testing

The second testing was tree testing on the medium fidelity mockup revised after the heuristic evaluation, which intended to measure the basic navigation and link structure of screens.

Tree testing is a usability technique used to measure the findability of topics in a website or app. We recruited five students from the CMU campus to do the first user test. The test included some pre-defined tasks for the user and the users were measured on factors, such as whether or not they were able to complete the tasks and how much time they took. The test was done on an android device running our prototyping software that displayed the medium fidelity mockups.
