SUMMARY This paper proposes an end‐to‐end flow controller for visual‐haptic communication. A visual‐haptic communication system transmits non‐real‐time packets, which contain large‐size visual data, and real‐time packets, which contain small‐size haptic data. When the transmission rate of visual data exceeds the communication bandwidth, the visual‐haptic communication system becomes unstable owing to buffer overflow. To solve this problem, an end‐to‐end flow controller is proposed. This controller determines the optimal transmission rate of visual data on the basis of the traffic conditions, which are estimated by the packets for haptic communication. Experimental results confirm that in the proposed method, a short packet‐sending interval and a short delay are achieved under bandwidth change, and thus, high‐precision visual‐haptic communication is realized. © 2013 Wiley Periodicals, Inc.
