Prototyping flexible touch screen devices using collocated haptic-graphic elastic-object deformation on the GPU

Rapid advances in flexible display technologies and the benefits that they provide are promising enough to consider them for futuristic mobile devices. Current prototyping methods lack facilities to simulate such flexible touch screen displays and the interaction with them. In this paper, we present a technique that provides product developers a tool to interactively simulate products featuring flexible displays, using Augmented Reality and Haptics. This GPU-based algorithm is computationally inexpensive and efficient to deform a polygonal mesh in real time while maintaining an acceptable haptic feedback. The implementation of the algorithm has been found to be successful when applied to a variety of product simulations. This simulation tool can enhance or even replace traditional prototyping and facilitate testing of the prototype at various stages of the design cycle.
