| Abstract | |
Mobile devices like smartphones and tablets enable rich and intuitive interactions, which brings new possibilities for users and developers. The high processing power, the constant improvement of user interaction, the ability to capture pictures and videos and the convenient way of accessing information and services are among the features that make them so popular. Over the past years we have been observing a growing in user generated content. In this context, modern mobile devices not only became popular media players, but also play an important role on multimedia content production. Furthermore, it is possible both to create new media and to enrich them with annotations. Annotations are usual in textual documents and recently became popular in pictures. Although applications for annotations are widely available for mobile devices, applications for mobile video annotation are still rare. The main objective of this research was to investigate interaction alternatives between users and their mobile devices considering the video annotation scenario. To investigate related problems, we have developed an application for tablets and smartphones with unique solutions for the proposed topic. With focus on human-computer interaction we conducted three evaluations: a usability evaluation with users, a heuristic evaluation with computer specialists and a collaborative assessment with a specialist in occupational therapy in the role of a user. Evaluation results helped to define new requirements and to identify issues that are not only applied in the video annotation context, but also in mobile applications in general. Thus, the main contributions of this study are solutions related to multimedia authoring, capture of interactions for video annotation on mobile devices and usability of applications. (AU) | |
