A Visual Approach supporting the Development of MicroApps on Mobile Phones

The definition of an approach supporting an EndUser in the development of mobile applications is a hard task because of the characteristics and the limitations of mobile device interfaces. In this paper, we present a visual approach to enable End-Users to compose visually their own applications directly on their mobile phone. To this aim, we propose a touchable interface and an ad-hoc visual language, enabling the user to compose simple focused applications, named MicroApps. The user has not in charge the creation of the user interface that is automatically generated. Moreover, we present the results of a preliminary usability study that revealed a good satisfaction degree of all the involved subjects, whereas an empirical analysis highlighted that the MicroApp visual approach is effective and efficacy.
