Recently, a transmission of tactile sensation has actively been researched following visual and audio information. In order to transmit tactile sensation to a remote place, it is necessary to utilize a network. However, there is communication delay in network, and it becomes difficult to realize 'law of action and reaction'. In order to guarantee constant transmission rate, a system secures communication band for a real-time communication such as video streaming. This method is called QoS (Quality of Service). Hence, this study evaluates the performance and proposes the index for QoS of haptic communication. In order to design QoS, this study considers QoE (Quality of Experience) and transmissibility by using experimental results of bilateral control.
