Upper-Arm Pointing Interface Using Orientation and Muscle Pressure

The patent replaces the mechanical mouse operation system with a physiological sensing system. Instead of requiring manual manipulation of mouse buttons and movement, the system uses pressure meters and orientation measurers to detect muscle movements and arm orientation, converting these physiological signals into cursor control commands. This substitution enables individuals with motor impairments to control the cursor through natural arm movements rather than requiring fine manual motor control.

The patent introduces an intermediary system consisting of pressure meters and orientation measurers that mediate between the user's physiological state and the computer control system. These sensors act as intermediaries by detecting muscle pressure and arm orientation, then translating them into meaningful control signals for cursor movement and button clicks, bridging the gap between impaired motor control and computer interaction requirements.

The patent applies universality by designing a system where pressure meters and orientation measurers serve multiple functions. The same sensor array can detect both subtle muscle movements for cursor control and larger arm movements for navigation, adapting to different user needs whether the user has partial motor control or is an amputee. This multi-functional approach reduces the need for separate specialized devices for different impairment types.

The system utilizes parameter changes by detecting variations in pressure and orientation parameters from muscle movements. The pressure meters measure changes in pressure magnitude and distribution, while orientation measurers track changes in arm angle and position. By monitoring these dynamic parameter changes rather than requiring static manual input, the system enables control for users with varying degrees of motor impairment.
