Abstract:
In recent years, many non-expert mobile applications have been deployed to query Geographic Information Systems (GIS) in particular Proximity Analysis that are concerned with the user who asks questions related to his current position by using a mobile phone. Thus, the new Iconic Visual Query Language (IVQL) has been developed and evaluated using a tourist application based on the map of Paris. The evaluation has been carried out to test the various usability aspects such as the expressive power of the language, the query formulation, and the user interface (GUI). The evaluation of the user interface that is hereby presented has been implemented through the user satisfaction of two subject groups, programmers and non-programmers. The results show that subjects found that the IVQL GUI has an excellent software, a good organization if icons, and is satisfying, with no significant difference between the two groups. The subjects also reported that they found the learning to operate the s
ystem easy, exploring new features easy, remembering the use of the icons easy, and performing tasks straightforward.
