Towards Action Track 3.0: The Role of Usefulness, Usability, and User Experience in a Startup Company Developing Location-Based Applications

This paper discusses the role of usefulness, usability, and user experience in a startup company focusing on location-based applications.

The learning process is discussed by the means of Action Track, a versatile but user-friendly authoring tool for developing location-based activities.
