Abstract This research paper represents a study and brief description on the behavior of Smart Wheelchair. In particular, a Smart Wheelchair could behave as autonomous agent by extracting information from the surrounding environment and determining its position in it, detecting the motion and tracking the behavioral patterns of other moving objects (automobiles) in its own surrounding space, exchanging information via internet with other moving objects (if possible) and negotiating its safety during travel with the other moving objects. Ideas And procedures are unified while developing a well structured concept of Smart Wheelchair which contains separate fully-functional units with their own characteristics interrelated to each other to conform a flexible system that can respond in an effective way to solve the problem of user. With this background, the main features of the user-wheelchair interface are discussed, justifying the need for the adoption of an adaptive approach. The smart wheelchair interface design is used to illustrate the design of user, context, and task models. In addition, it describes some mechanisms to enhance the communication rate when a single-switch-scanning input device is used (scanning rate dynamic adaptation and word prediction). The chapter finishes with a discussion of the influence of new navigation models, such as the behavior-based one, in the design of the user interface. 1. Overview This research documents a study and brief description on the smart wheelchair also suggesting a possible prototype of the envisioned application. Smart power wheelchair, whereby the term “smart” means a power wheelchair whose motion is mediated by a computerized system which is aware of the environment and can collaborate with the user to achieve mobility goals and avoid dangerous situations. The recent development in research areas such
