Use of Multiple Parallel Interface Strategies To Create a Seamless Accessible Interface for Next-Generation Information Systems.
Vanderheiden, Gregg C.
Information systems in public places such as community centers and libraries require some means to provide access to individuals with physical, visual, and, if sound is involved, hearing impairments. This paper proposes a seamless adaptable human interface protocol that would allow users to incrementally modify the command and presentation aspects of the human interface to match their abilities and preferences. The protocol supports multiple control strategies (mouse, keyboard, touchscreen) and presentation forms (standard graphic, large print, voice) simultaneously. In order for the command and control structures to support flexibility and a free flow, a multilevel object-based hierarchy was used. The first implementation of the protocol is in a bibliographic database software package titled Publications, Media and Materials (PMM), which was developed for the Trace Cooperative Electronic Library. Strategies to increase efficiency of access are discussed. Screen displays in various output modes are presented, along with a table listing protocol features for individuals with specific types of disabilities. (JDD)
