The high force update rate is a key factor for achieving high performance of haptic rendering, which imposes a stringent real-time requirement upon the execution environment of the haptic system. To fulfil this requirement, haptic systems are often limited to simplified virtual environments (VEs) for reducing computational load. This paper presents a novel pipelined threading architecture, which uses several threads running consecutively for implementing haptic rendering algorithms. With the proposed method, the haptic forces updating rate is effectively increased, which leads to improved system performance and makes complex VE scenes possible in haptic rendering. Based on the 3-DOF Delta haptic device, experiments with a virtual wall haptic system are carried out and verify the proposed method.

High force update rate is a key factor for achieving high performance haptic rendering, which imposes a stringent real time requirement upon the execution environment of the haptic system. This requirement confines the haptic system to simplified environment for reducing the computation cost of haptic rendering algorithms. In this paper, we present a novel "hyper-threading" architecture consisting of several threads for haptic rendering. The high force update rate is achieved with relatively large computation time interval for each haptic loop. The proposed method was testified and proved to be effective with experiments on virtual wall prototype haptic system via Delta Haptic Device.

This paper considers moments due to friction forces on the human fingertip. A computational technique called the friction moment arc method is presented. The method computes the static and/or dynamic friction moment independent of a friction force calculation. In addition, a new finger holder to display friction moment is presented. This device incorporates a small brushless motor and disk, and connects the human's finger to an interface finger of the five-fingered haptic interface robot HIRO II. Subjects' perception of friction moment while wearing the finger holder, as well as perceptions during object manipulation in a virtual reality environment, were evaluated experimentally.
