Developing technologies to provide haptic feedback for surface based interaction in mobile devices
Touchscreens are becoming a more attractive interaction technology in our daily lives and they are quickly replacing most of the conventional user interface controls. The ability to continuously modify and reconfigure screen content is a valuable feature in any system, especially in mobile devices; like smartphones and tablets, where every inch matters.
Perhaps the most inviting aspect of touchscreens is their ability to also detect gestures and recognize human activities beyond the normal press and click interaction. Unfortunately, these virtual controls do not compliment user interaction by providing meaningful haptic feedback. In the absence of conventional tactile feedback to support the distributed visual attention, users run into a number of issues experiencing difficulties in distinguishing between contact positions and desirable selections. To resolve these issues, we have been developing a wide array of techniques that can simulate touch feedback on interactive surfaces. This thesis builds on these techniques by analyzing the current approaches to haptic feedback in general, and the methods of applying vibrotactile signals to the human skin contact, specifically. The thesis identifies possible shortcomings of the existing approaches of generating and transmitting vibration based signals to the skin, and also provides alternative methods.
And finally, the thesis aims to create a more holistic approach to haptic research and multimodal interaction, by suggesting a transition from the classical methodology of Von Neumann Architecture, as interaction with computing systems moves from physical to virtual interaction, and system outputs require haptics along with visual and auditory modalities.
