Much attention is paid to the advantage of auditory perception over visual perception in human computer interaction and its influence on the choice of data-sound mapping algorithm.

It has been shown that when the phase spectrum in speech is changed and it s amplitude spectrum is kept constant, there is no different auditory perception between the original speech and the reconstructed speech if the envelope of the reconstructed speech signal is not changed.

This paper studied the speech enhancement algorithms based on the characteristics of auditory perception in time-frequency domain, the main work are as follows:1.

Swimming perception teaching method and its experiment;

Application of Perception in Tourism Spot Exploition;

Recent studies revealed that pain perception is formed via large-scale coding processes in central neural networks, involving several dimensions such as sensory, affective, and cognitive.

Research and Realization of Model Simplification Based on Visual Perception;

A kind of watermarking algorithm Based on wavelet and fuzzy visual perception

In order to enrich perceptive abilities of artificial fish and exhibit vivid animation, a kind of virtual smelling perception system of artificial fish was proposed based on analysis of the olfaction mechanism of natural fish and perception system of "robot fish".
