Perceptual interfaces in human computer interaction

Humans are viewed as efficiently processing multiple sources of information supporting their interactions with the world and with others. This theoretical framework has been successful in predicting for a wide variety of research findings, as well as rationalizing everyday experiences. Existing controversies over perceptual interfaces are considered in terms of this framework. The conclusion is that both inputs and outputs in human computer environments should be characterized by many different sources of information from multiple modalities
