N2 - This paper presents Depth Image-Based Haptic Rendering (DIBHR), a haptic rendering algorithm that enables users to haptically explore 3D video media based on depth image-based representation (DIBR). The algorithm computes the shortest proxy (god-object) path along which the proxy goes into the local distance minimum to the goal (haptic interaction point) constrained on surface in order to obtain correct friction force when the friction cone algorithm is applied. This algorithm is based on the god-object [3] concept and adopted the neighborhood search algorithm [5][6]. The experiments compare DIBHR with two previous algorithms [5][6] as per computation time and smoothness of resultant force rendering. The results show slower computation time yet within 1 millisecond and smoother force with friction.
