Environmental control system for the handicapped
First Claim
1. A method for providing a handicapped user with control over his environment comprising the steps of(a) presenting, one at a time in a predetermined sequence, a first set of options to said user;
- (b) selecting one of said options within said first set in response to user manipulation of a control having first and second active positions in synchronism with the time said one option is presented to said user;
(c) presenting one at a time, in sequence, a further set of options different from said first set of options to said user in response to said selecting step (b);
(d) subsequent to said step (b), repeating said presenting step (a) in response to further user manipulation of said same control to said first active position;
(e) selecting one of said options within said further options set in response to further user manipulation of said same control to said second active position in synchronism with the time said one of said further options is presented to said user; and
(f) controlling the operation of an appliance in response to said selecting step (e).

Abstract
An environmental control system for the handicapped provides a user interface which is totally integrated and programmable. An audible nested control option selection structure organizes logically related tasks and subtasks together so the user can access the tasks and subtasks in a natural fashion--providing an easy to learn user interface that is user friendly, minimizes frustration in accomplishing desired tasks, and also minimizes the time required to perform even complex control operations. Enhanced user interface features, including time encoding of control switch functions and synthesized speech prompting, further increases ease of operation and functionality. Interaction between different control channels allows the user to perform different tasks simultaneously. Enhanced telephone line manipulation is provided, including off-line assembly of telephone numbers for dialing which can be stored and easily accessed by the user through the unified audible sub-menu structure. Sharing of common hardware for multiple functions minimizes system cost, increases reliability and makes the system easier to use.

10. A method for providing a handicapped user with control over his environment comprising the steps of:
-
(a) providing said user with an input switch having first and second alternate active positions and a third, inactive position; (b) audibly prompting said user with a sequence of options defined by a predetermined root control sequence; (c) selecting one of said root control sequence options in response to user actuation of said input switch to one of said active positions in synchronism with the time said one option is presented to said user; (d) audibly prompting said user with a sequence of sub-options associated with said option selected by said selecting step (c); (d) repeating said prompting step (b) in response to further user actuation of said input switch in said first active position; (e) selecting said one of said sub-options in said sub-option sequence in response to further user actuation of said input switch in said second active position in synchronism with the time said one sub-option is presented to said user; and (f) controller at least one operating parameter of an appliance in response to said selecting step (e). - View Dependent Claims (11)

12. An environmental control system for providing a handicapped user with control over his environment, said system of the type adapted for connection to a user-operable input switch having first and second alternate active positions and a third, inactive position, said system comprising:
-
means for providing a root control sequence including plural control options and for providing plural sub-function control sequences corresponding to and associated with said plural root control sequence control options, each of said plural sub-function control sequences including plural control sub-options ; prompting means connected to said storing means for prompting said user one at a time with a sequence of audible prompts corresponding to said root control sequence control options; processing means, connectable to said input switch, for; (a) selecting a sub-function control sequence corresponding to a first root control sequence control option in response to user actuation of said input switch substantially in synchronism with the time the audible prompt associated with said first root control sequence option is provided by said prompting means, said prompting means audibly prompting said user with said sub-option control sequence in response to said selecting by said processing means, (b) selecting one of said plural control sub-options in response to user actuation of said input switch to said first active position substantially in synchronism with the time said audible prompt associated with said one control sub-option is provided, and (c) controlling said prompting means to again prompt said user one at a time with said sequence of audible prompts corresponding to said root control sequence control options in response to user actuation of said input switch to said second active position; and function performing means connected to said processing means for performing a predefined function associated with said one control sub-option in real time in response to selection of said one control sub-option by said processing means. - View Dependent Claims (13)
