ABSTRACT

Human sensory systems, such as the eyes and ears, are central to successful interaction between users and technology. As the incidence rate of sensory impairments continues to increase, adaptations must be incorporated into computing and information technologies to accommodate the rising needs of users experiencing sensory defi cits. is chapter will discuss the general structure and function of the primary human sensory systems-vision, hearing, and touch-that are vital and intrinsic to human-computer interaction (HCI), as well as some examples of common sensory-specifi c impairments that may aff ect HCI. e sensory systems reviewed in this chapter include the visual system, the auditory system, and the haptic system. Following the review of sensory systems and related impairments, some of the recent technological developments used to enhance the sensory experience of users with impairments will be discussed.
