摘要:

This paper describes and discusses a strategy for the design of an expressive communication aid for the non-vocal which is highly flexible and which embodies the principle of user-specifiable function. Some of the implications which arise when an intuitively common system configuration is adopted in practice are examined. It is shown that a principal feature of the design process and subsequent assessment of the system is the way in which modelling of processes, mechanisms or functions provides a common focus for establishing the important criteria for system design and evaluation of its applicability.

摘要:

In this paper two projects on speech communication aids for the speech-impaired are discussed. Since the group of speech-impaired people is very diverse, the two projects differ in target group, in the speech technology used and consequently in the complexity of input of the aids. In both projects (Pocketstem and Tiepstem) experimental models have been developed, and in the case of Pocketstem prototypes have been developed and evaluated by potential users. This paper describes the aids, their evaluation, the evaluation results and some conclusions and future plans.

摘要:

A computer-based communication system for non-verbal persons with severely deficient coordination of the upper extremities is described. The device doubles as an environmental control unit. Modular design is chosen throughout. Commercially available subunits are used to reduce cost. Input is by a 3×3 keyboard, when the user has some command over his hands. Otherwise a binary‘autoscan’access mode is used, which is controlled by repeated closures of a single binary switch. Output is in written form on a display or acoustical by synthesized speech. Hard-copy output can also be provided. Remote communication is possible by modem or by synthesized speech. Speed of message generation is increased by establishing a vocabulary, which contains, in addition to signs and letters of the alphabet, whole words and stereotyped phrases. The data blocks of the latter are accessed by a single input cycle similar to that used for the selection of isolated letters, symbols, etc.

摘要:

JAL2 is an integrated tool which enhances communication skills for people - mainly those with cerebral palsy - who suffer from any kind of disability that prevents speech. JAL2 can be used as a portable communicator and has an editor which can construct any text. It can also substitute for the keyboard of a personal computer, allowing the disabled the use of these machines. Furthermore, it is used to control one's personal environment by means of an infra-red transmitter. All of these options, scanned on a display, are accessed through a push-button.

摘要:

Motor-and speech-impaired people can have severe problems with communication. If speech is hampered, the use of computerized communication devices can be a solution. Key entry limitations due to motor impairments may result in very low communication speeds - less than three words a minute is not unusual.The research described here deals with speed enhancement on the basis of redundancy in language. Two uses are explored: prediction and automatic decoding in the case of keyboards with a small number of keys.Prediction means that characters, words and (parts of) sentences are predicted on the basis of text which is already typed in. A prototype system is being designed which combines the features of the PAL prediction system from Dundee and the WRITE-keyboard from Boston.Decoding refers to two-step selection systems with a small number of keys in which the second selection is done automatically by a computer program. Keystroke savings of 40 to 50% are possible.

摘要:

A UMIRTX robot, modified with limited end-effector sensors and a restricted but effective vision system, is currently used in a developmental education setting for severely physically disabled children. The low physical and cognitive abilities of the children involved in the project require a semi-autonomous robot with environmental sensing capability to operate in a task oriented mode. A variety of low-cost sensors including proximity, distance, force and slip sensors, have been investigated for integration in end-effectors for the RTX robot. The sensors employed on a modified end-effector are detailed and experimental results are presented. A design for an end-effector with integrated sensors is discussed. The integration of the sensor information into a high-level, task-oriented programming language is detailed and examples of high-level control sequences using sensor inputs are presented. Finally, the development of intelligent gripping strategies based on sensor information is discussed.
