Abstract
A system for use by persons who may have muscular incoordination and/or spasticity or the like is provided with means for controlling the disabling of a function producing means depending upon the person's motor capability. A disabling circuit is responsive to an actuation of any of a variety of input interface means whereby subsequent actuations of the input interface means prior to the expiration of a variable, predetermined disabling time interval produce no function.
Claims3
A method of communication and/or control for persons who are handicapped including reducing the probability of error due to insufficient motor control, muscular incoordination spasticity and the like, comprising:
- a. establishing for every function in a multiplicity of functions a unique combination of designators;
- b. generating a pair of complete man-machine language output signals representative of two of said unique designators;
- c. providing at least one actuatable interface means for selectively generating said output signals upon at least a dual actuation of said input interface means;
- d. connecting utilization means to the pair of output signals for producing a function commensurate with actuation of said input interface means,
- e. disabling said producing means for a time delay interval which may be selectively varied whereby said producing means is rendered impervious to subsequent actuations of said input interface means prior to expiration of the time delay so that spastic or other extraneous movements by the handicapped operator causing inadvertent actuations of said input interface means do not produce undesired functions.
