Ambiguous keyboards provide efficient typing with low motor demands. In our project l concerning the development of a communication aid, we emphasize adaptation with respect to the sensory input. At the same time, we wish to impose individualized language models on the text determination process. UKO–II is an open architecture based on the Emacs text editor with a server/client interface for adaptive language models. Not only the group of motor impaired people but also users of watch–sized devices can profit from this ambiguous typing. . | Towards an Adaptive Communication Aid with Text Input from Ambiguous Keyboards Karin Harbusch Michael Kiihn University Koblenz-Landau Computer Science Department Universitãtsstr. 1 D-56070 Koblenz GERMANY harbusch kuehn @ Abstract Ambiguous keyboards provide efficient typing with low motor demands.

Computer assisted text entry methods such as ambiguous keyboards are feasible for synchronous and even for asynchronous communication scenarios as they allow complex communication on small electronic devices. Various systems on the mobile phone and handheld market promise a solution to easier and faster text entry. People with communication disorders are a second group of users who can benefit from lrThe project is partially funded by the DFG German Research Foundation under grant HA 2716 2-1. computer-assisted text input. Often speech impairments coincide with severe motor impairments. Standard keyboards or graphical input devices are often unsuitable for motor impaired users. Sometimes only the operation of one or a very small number of physical switches is possible via buttons joystick eye-tracking or otherwise. These two contexts of use are considerably different Mobile communication typically happens in the context of asynchronous telecommunication although
