摘要：
We investigate predictive coding for reducing the amount of data communicated between a haptic controller and a host. This allows increased update rate, which potentially improves quality even if coding is lossy. A low-order predictive coding is investigated for a pneumatic force display. Due to human and device characteristics, some compression is possible without loss, although the technique is lossy in general. Lossy uniform and nonuniform quantizers are also investigated. An experiment was conducted to determine how much data reduction is possible before compression artifacts become detectable to users.
