In this paper, we propose communication schemes using error control based on importance for remote haptic instruction systems in which an instructor trains a learner at a remote location how to write characters or draw figures while conveying the sense of force. The schemes carry out error control only over important media units (MUs) which include the position information in the case where the speed of the brush stroke is faster than a threshold value. For the error control, we adopt Replication, which sends each MU twice, Forward Error Correction (FEC) with XOR calculation or Reed-Solomon coding, and so on. By subjective assessment, we demonstrate the effectiveness of the proposed schemes.
