We studied QoS (Quality of Service) control to achieve high-realistic sensations for several networked applications with visual, auditory, haptic, and olafactory media. We also studied QoE (Quality of Experience) assessment methods to assess realistic sensations. In QoE assessment, we investigated the influences of network delay and packet loss on human perception, and demonstrated that we can estimate subjective assessment measures from objective assessment measures with high accuracy for several applications. Furthermore, we handled adaptive reaction force control, media synchronization control, local lag control, and dynamic output timing control of fragrance as QoS control and illustrated the effectiveness of the control.
