Stage 3 - Evaluating usability of GeoFARA
(A conceptual model of user-mobile device context-aware interactions, Li and Willis 2006)
• Mobile application usability: the extent to which a mobile application can be
used by specified users (with various modalities of mobility) to achieve specified
goals with effectiveness, efficiency, and satisfaction in a specified user context.
• GeoFARA’s usability—the extent to which GeoFARA can be used by students
(when visiting the fieldwork area) to achieve spatial cognition with effectiveness,
efficiency, and satisfaction.

17. 17
Methods Purposes
Online survey To recruit representative users
Clickstream/Log capture To capture the user’s finger-touch on the phone screen (touch heat map)
Mobile eye tracking To record the user’s eye movements among GeoFARA and environment
Thinking aloud To obtain the user’s simultaneous ongoing thoughts
Camera/video studies To record the user’s behavior and the whole process
User observation To observation the user’s behavior
Task analysis To evaluate GeoFARA’s effectiveness, and efficiency
Post-task survey, interview To collect the user’s overall experience towards GeoFARA
Methods of evaluating usability of GeoFARA
