1. An improved method of selecting an element of a group comprising steps of:
- (a) serially scanning the elements of the group at a rate which is proportional to a user controlled continuously variable volitional signal;
(b) stopping said serial scanning step under an ambient condition.(c) selecting the said element of the group by changing the user controlled volitional signal in a direction or magnitude different from that which is applied under scanning step (a).

Abstract
A method and apparatus allows a user to scan through a predetermined character set through the implementation of a continuously variable volitional signal, and for selecting a specific character. The scanning rate is proportional to the user controlled volitional signal.

12. A communication method, for use by handicapped individuals for selecting an element of any array, comprising steps of:
-
(a) serially scanning the elements of the group at a rate which is proportional to a user controlled continuously variable volitional signal; (b) stopping said serial scanning step under an ambient condition. (c) selecting the said element of the group by changing the user controlled volitional signal in a direction or magnitude different from that which is required for said scanning step (a). - View Dependent Claims (13, 14, 15)

16. An apparatus for aiding handicapped persons in selecting an element of an array, comprising:
-
means for sequentially generating coded signals corresponding to the array elements; means for serially scanning the elements of a group at a rate which is proportional to a user controlled continuously variable volitional signal; means for selecting said element of an array upon signal threshold limits, switch closeure, or the combination of a multiplicity of applied control sources. - View Dependent Claims (17, 18, 19, 20)
