“…Tougaard and Gong explained the SR in human sensory modalities through signal detection theory [12][13] [14]. Liu Jun analyzed the non-linear characteristic and utilized neuronal network to model the sensory system [15]. Using numeric simulation, the SR behaviors were exhibited and the comparability of the numeric models were proved.…”

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 interface.
