Data entry in application-independent voice interfaces

Complex graphical portals present multiple applications to users in a single display. However, portal interfaces are heavily mouse and keyboard intensive, making them inaccessible to users with physical disabilities. We are investigating the design of application-independent voice interfaces to add accessibility for physically disabled users to pre-existing applications. This paper describes a user study comparing voice data entry to keyboard and mouse, to assess efficiency and user satisfaction. Feedback and results show voice data entry to be useful, although some performance issues still remain.
