Tangible Images

Enabling haptic sensation in images can lead to very exciting developments, as we believe this can pave the way toward ‘movie haptics’, that is an algorithm that allows users to interact with video sequences in a sufficiently realistic manner. Generation of textures is widely known in computer graphics and haptics. In graphics they are created to produce a realistic look for the surface, which is accomplished mainly through various reflection models. In haptics, textures serve a similar purpose; they are used to increase the realism of haptic interactions. In this work we propose a common method to achieve two very different goals in haptic rendering, one of them is to enable haptic sensation in two dimensional images, the other is to generate haptic textures in a simple and efficient manner. We describe an algorithm that allows the generation of forces from two dimensional images, the forces allow the user to feel the contours of the image with sufficient realism. The algorithm can also be used to generate textures for virtual surfaces in a simple and efficient manner. We also describe the design of the mask to be used to achieve the above two objectives and discusses the factors affecting the performance of the algorithm.
