Passive Haptic Data-Compression Methods With Perceptual Coding for Bilateral Presence Systems

In this paper, lossy compression methods for haptic (velocity and force) data as exchanged in telepresence or virtual reality systems are introduced. Based on the proposed interpolative and extrapolative compression strategies, arbitrary passive compression algorithms can be implemented. The derived...

Summary:In this paper, lossy compression methods for haptic (velocity and force) data as exchanged in telepresence or virtual reality systems are introduced. Based on the proposed interpolative and extrapolative compression strategies, arbitrary passive compression algorithms can be implemented. The derived algorithms do not affect the stability of the presence system. Two algorithms were implemented and experimentally evaluated. The results show that constant data rate savings of 89% still lead to a perceptually transparent presence system.
