Location-aware applications: evaluating the ease of use and ease of learning
Our study investigates the ease of use and ease of learning of Location Based Services (LBS) and their effect on WAP (Wireless Application Protocol) applications. In particular, we evaluate the effect of using LBS on the design of the user interface, task structure, user perception, user satisfaction, effectiveness and efficiency and of the application. A traintimetabling prototype was developed for this purpose. The system consists of two components: one that emulates a LBS enhanced system and the other that does not. A comparison, within subject, empirical usability experiment was also designed in order to test the same participants across all scenarios and draw conclusions. The users were asked to retrieve information pertaining to travel time and destinations, fare prices and ticket outlets. We found that LBS functionality does enhance the WAP applications by overcoming some of the limitations associated with WAP.
