Talking keyboard for user guidance in multifunction systems
Abstract
For the important task of function selection when using technical systems e.g. measurement or programming devices a talking keyboard is proposed which offers user guidance adapted to man's skills. This keyboard is equipped with a voice output module and special keys fitted with two sequentially activated switching contacts. By means of the first contact the user is enabled to select vocal user guidance information whereas by the second contact the selection of a particular function is achieved. By closing the first contact repeatedly spoken hints with more and more details are available. The user can, however, suppress or interrupt these instructions by switching over to the second contact. In this way the talking keyboard may be used adaptively by trained and untrained users as well. Furthermore it is suited for blind operation under severe visual load conditions or in the dark and it serves to the visually handicapped. (IITB)
