Nouvelles interactions physiques pour dispositifs mobiles

Abstract : Sixty percent of the world's population now owns a mobile phone. Recent models, which tend to become small laptops are up to 10 000 times more powerful and 300 000 times less heavy than the first computer, appeared 60 years ago. Despite this power and all the resources provided by modern equipment (touchscreen, accelerometer and other sensors...), mobile phones suffer from certain limitations due to the lack of conventional input such as keyboard and mouse. To increase the interaction bandwidth of these device and take advantage of these sensors, we investigate the potential offered by gestural interaction by considering two lines of research: movements on the mobile and movements of the mobile. After defining a classification space we conceived and developed several gestural interaction techniques to enrich and facilitate interaction between the user and these devices. For the movements on the mobile we have proposed to improve the flick, a scrolling technique widely popularized in recent years. We first studied his ‘anatomy’ of this technique, then we proposed to exploit multiple interactional resources hitherto unused. This work gave birth to three new techniques: Flick-and-Brake and LongFlick, that respectively use the pressure on the screen and the characteristics of the throwing action to better control scrolling, and Semantic Flicking which leverage on document semantics to facilitate reading. In a second stage we considered the potential of 3D interaction, by moving the mobile device in the space. This line of research aims at expanding the interaction vocabulary while avoiding interferences with existing touch interactions. Leveraging on integrated sensors such as accelerometers, we proposed two new techniques for 3D interaction: TimeTilt, which uses smooth and impulsive gestures to easily navigate between different views, and JerkTilt, which introduced the notion of self-delimited gestures for accessing quickly to commands. An interesting property of these self-defined gestures is their ability to be combined with common interactions on the screen. We thus finally considered the combination of modalities offered by the two and three-dimensional gestures.
