Research on Improving the Haptic Texture Display Using Stochastic Noise

摘要：

Stochastic resonance has been found to be a common mechanism in a variety of physical and biological systems including signal transduction in human audition and vision. It was supposed that adding stochastic noise signal to the texture force model could enhance the realistic of haptic texture display. Based on this assumption, the prior texture force model based on image processing was improved by adding the white Gaussian noise, and the haptic texture display interface was constructed based on DELTA haptic device. The texture perception experiments were carried out. The experiments showed that people can achieve more remarkable texture perception when adding an appropriate noise signal to the original texture force, and subjects can obviously distinguish the texture images with the haptic texture display inte rface.
