中文摘要:

      分析了温度触觉感知特性，提出了手指和物体接触时各自表面的温度变化过程，结合单热源温度触觉再现装置设计了一种基于三维力反馈手控器的虚拟环境温度触觉再现仿真系统。手控器可控制虚拟手的动作，对虚拟物体进行温度和力的感知。仿真系统中能再现手指与不同热属性物体接触时的温度变化和力变化，且视觉效果逼真,体现了温度触觉再现的实时性和有效性。

英文摘要:

      The speciality of thermal tactile display is analyzed,the surface temperature changes of the finger and object during hand object interactions are proposed.A virtual environment thermal display system based on three dimensional force reflecting hand controller is developed with a thermal display device.The controller can control the action of the virtual hand and sense the changes in temperature and force at the moment of contact.The simulation system could display the temperature changes and force changes when the finger touches different thermal properties of objects with accurate visual effects,which also embodies real time and effectiveness of thermal tactile display.
