Providing rehabilitation integrated systems using existing rehabilitation technology

Achieving appropriate integration of control of multiple assistance devices for an individual is currently limited by available integrated systems. An overview of the provision process for Rehabilitation Integrated Systems (RIS) is presented which stresses the need for detailed assessment of the individual's abilities and requirements. A software system is described which integrates existing assistive applications on a PC in an attempt to provide a flexible RIS which can be tailored more precisely to an individual. This has required the use of both DOS and Windows applications and highlighted problems due to limitations of existing RISs, despite user requirements being taken fully into account. While Windows offers the opportunity to remove some compatibility problems, it is concluded that interfacing standards for both software and hardware are necessary to overcome the problems this approach engenders. For individuals who have to use 'intrinsically slow' user interfaces, it is identified that (i) the availability of quantitative comparisons of efficiency of selection methods and (ii) increased choice of selection methods is important.
