Studies show that every fourth smartphone user watches videos on their device. However, because of increasing camera and encoding quality more and more smartphones are providing an attractive tool for creating and editing videos. The demand for smooth video browsing interfaces is challenged by the limited input and output capabilities that such mobile devices offer. This paper discusses a novel interface for fast and precise video browsing suitable for watching and editing videos. The browsing mechanism offers a simple but powerful interface for browsing videos at different levels of granularity. All interactions can be carried out with no modal changes at all. The interface is easy to understand and efficient to use. A first evaluation proves the suitability of the presented design for casual users as well as for creative professionals such as video editors.

With the advent of modern mobile phones and tablet devices unprecedented opportunities arise to create rich user experiences that incorporate the context in which the interaction is situated. Sensors and other built-in technologies provide designers with a variety of possibilities for new and exciting applications. Since building such applications requires specialists there is an increasing demand for tools supporting people without programming skills to access, explore and design for the opportunities of mobile devices. In this paper we present a novel prototyping system named FamOz that combines the ease of paper prototyping with the efficiency of Wizard of Oz while exploiting the interactivity offered by new mobile devices. FamOz allows designers and researchers to evaluate mobile prototypes in situated realworld settings in an early stage of development.

The long-term effects of visual impairments can, in some instances, be mitigated if the sensory cells in the eye are trained appropriately during (early) childhood. Exposure to visual stimuli like cardboards with high-contrast visual patterns is the cornerstone to a successful treatment. However, despite its benefits, this kind of vision training can be tedious and demotivating for children. To leverage training and therapy, we propose interaction design to create multimodal stimuli that are rewarding and motivating. The present work elaborated on this suggestion and presents a design concept that makes the vision therapist a playmaker, coach, playmate, wizard, and statistician all at the same time.Visual impairment.
