A low cost touch-screen interface for image collage

this paper presents the design of a low-cost interface based on touchscreen interaction. the interface is developed for rehabilitation purposes, such as, stimulating cognitive development and motor skills as well as creativity and expressibility. the touch-screen interaction design is based on a wii remote system. we compared two system versions. the first is based on touch-screen interaction design and the second is based on mouse interaction. although the wii remote has low resolution the experimental results showed that users had a better performance with the touch-screen version when carrying out activities that require fine motor skills such as delineating free shape figures.
