一种新的虚拟纹理触觉再现方法及其装置实现

A New Design of Haptic Texture Display

根据人的触觉是动态触觉的原理,提出了一种新的纹理触觉再现方法及其实现装置,该装置能在使用者手指端部产生类似于纹理感觉的触觉信息。它的主要组成部分是铝合金制成的圆筒,上面分布着大小不同的凹孔和凸点,通过伺服电机带动它旋转。手指在匀速旋转的圆筒上来回滑动并触摸上面的凹孔与凸点,能有明显的触觉感受,而且不同的旋转速度将会带来不同的触觉效果。通过对该实验装置进行大量实验,统计归纳出实验者在各种情况下所获得的触觉感受,证实该装置在模拟纹理触觉方面确有成效,对纹理触觉的发展起到一定的促进作用。

A new design of haptic texture display that evokes a virtual touch sensation of texture surfaces contacted to the user＇ s finger-pad is described. Cylinder made of aluminum alloy is driven to rotate by servo motor through a shaft. The user places his or her finger on a small window and moves back and forth while feeling slip. Through many experiments, every user＇ s feeling together under different circumstances is obtained, and then a primary conclusion can be given out.
