10.6. Summary
The topic of perceptual interfaces is very broad, covering many technologies and their applications in advanced HCI. In this chapter, we gave an overview of perceptual interfaces and went a bit deeper into how the field of computer vision can contribute to the larger goal of natural, adaptive, multimodal, interactive interfaces. Vision-based interaction (VBI) is useful in itself, providing information about human identity, location, movement, and expression through noninvasive and nonintrusive methods. VBI has many near-term application areas, including computer games, accessibility, intelligent environments, biometrics, movement analysis, and social robots.
If the technical goal of building perceptual interfaces can be achieved ...
