マルチラテラル遠隔制御理論に基づくハプティックネットワークゲームの作成と通信遅延がQoEに及ぼす影響の調査(<特集>ハプティックコンテンツ)

In this paper, the influence which it has on &quot;Quality of Experience&quot; (QoE) in the haptic network game is discussed. First, the control method for the haptic network game, in which a continuous dynamic interaction such as tug of war is realized, is described. Second, the subjective and objective evaluations of QoE are performed through a &quot;Falling guidance game&quot; using the proposed control method. Although QoE&#39;s deteriorates according to increase of communication delay is investigated in the five-step evaluation with MOS (Mean Opinion Score), it becomes clear that the degradation of QoE is not worried for a player in the range of domestic communication delay. Moreover, in regression analysis, it is suggested that the improvement of a future haptic network game should be done by a visual sense rather than the viewpoint of haptic sense. The proposed control method is considered that it is an adequate algorithm for practical use of a haptic network game since it can realize a dynamic interaction stably also in the environment of RTT (Round Trip Time) = 400 [ms].
