In the design of information symbols in human-computer interface, one meaning usually has several design forms. In order to solve cognitive deviations generated during information exchange, in the paper, we tested the recognition rates of common information symbols. The testing results indicated that users under different cultural backgrounds showed significant differences in information symbol cognition. Users prefer to clear and concise information symbols. Users are inclined to understand the surface meaning of information symbols. Through the study of the recognition rates of typical information symbols, we established the perceptual confusion models of information symbols. Based on different models, designers can improve cognitive deviations of existing symbols and design information symbols, which are consistent with user cognition, for reasonable human-computer interaction.
