Abstract: A controller is communicatively coupled to the one or more user input devices, such as sensors or electrodes, a user interface device, and one or more switch-controlled devices. The controller presents a configuration user interface on the user interface device including selectable configurations for access modes. The controller assigns one or more of the user input devices according to a current selected configuration of an access mode. The controller detects a volitional user input corresponding to a change in a particular signal detected by a particular user input device and switches the switch-controlled device based on the detected user input. In one or more embodiments, the system includes one or more biosignal electrodes attachable to a user and/or mechanical, positional, or other switch technologies. In one or more embodiments, the system includes one or more sensors for detection of movement, gestures, eye tracking or other input.

Abstract: A method, human interface device, and computer program product that provide improved multilevel switching from each bioelectrical sensor with inclusion of switch filtering based on extraneous events (e.g., spasms). A biosignal is received from a sensor device by an electronic processor of a first electrode switch device. In response to determining that the amplitude of the signal has changed from less than a first switch range to greater than the first switch range and less than the second switch range, the electrode switch device communicates a first switch signal to control the human interface system. In response to determining that the amplitude of the biosignal has changed from less than the second switch range to greater than the second switch range, the electronic switch device performs one of: (i) ignoring the instance and (ii) transmitting a second switch signal to control the human interface system.
