摘要：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.
