摘要
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.
