“…Another delay concealment technique, presented in [16], utilizes a Delay Synchronization Module (DSM) at the server and Delay Modules (DMs) at each client. The idea is to delay haptic rendering at each client (buffering incoming data) until all clients can do so simultaneously.…”

“…Jitter concealment has received less attention than delay concealment in the literature. Reference [16] presents a jitter concealment technique through the use of a Prediction Module (PM) to compensate for jitter and packet loss in their CS architecture DHVE. The idea behind the PM is that the client expects to receive an update from the server every millisecond.…”

Haptic sensory feedback has been shown to complement the visual and auditory senses, improve user performance and provide a greater sense of togetherness in collaborative and interactive virtual environments. However, we are faced with numerous challenges when deploying these systems over the present day Internet. The most significant of these challenges are the network performance limitations of the Wide Area Networks. In this paper, we offer a structured examination of the current challenges in the deployment of haptic-based distributed systems by analyzing the recent advances in the understanding of these challenges and the progress that has been made to overcome them.

“…[11][12][13] To this end, the most often used technique is a time-stamp based approach, which is effective for the synchronization between audio and video data. 14 More recently, multimedia synchronization techniques over networks have also been investigated, including haptic collaborations, 15 tele-haptics, 16 haptic tele-surgery, 17 and haptic telementoring, 18 which enhance a person's perception and manipulation capability by smoothing remote operations. An adaptive buffering control method has been proposed for haptic media synchronization in networked virtual environments.…”

In multi-modal interactions including haptics, problems such as input sensor noise, temporal mismatch between graphics and haptics, and non-constant refresh rates may cause non-smooth force/torque display. This paper proposes temporal smoothing technique for haptic interaction using a sensing glove in multi-modal applications. The proposed technique employs two processes: (1) a noise reduction method is applied to reduce jitter noise at the sensors in the sensing glove and (2) an adaptive force extrapolation is applied for timevarying haptic and video frame rates. To demonstrate the performance of the proposed method, we developed a test platform to assess a simple box model and relatively complex models such as gamephone, portable media player (PMP). It was subsequently demonstrated that the proposed method can support smooth haptic interactions in multi-modal applications where a haptic device and a sensing glove are used.

Remote surgery information requires quick and reliable transmission between the surgeon and the patient side. However, the interconnecting network is usually time varying and lossy which can cause packet loss and delay jitter. In this paper we introduce an adaptive packet prediction and buffer time adjustment algorithm which reduces the negative effects caused by the time varying networks on the transmission of force feedback data. To evaluate our scheme we run a virtual reality applet built in Matlab. Our results show, for severe packet loss and variable delay jitter, the integrated synchronization technique significantly improves the performance of the force feedback device.
