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.

Abstract: A system includes a processor in communication with a set of bioelectrical sensors and a user interface device that provides functionality to monitor one or more bioelectrical signals from a set of bioelectrical electrodes. Processor automatically adjusts a selected one of: (i) a resting threshold; and (ii) a switch threshold that is greater than the resting threshold based at least in part on a trend of the bioelectrical signal. The processor determines whether an amplitude of the bioelectrical signal is less than the resting threshold. In response to determining that the amplitude is less than the resting threshold, the processor determines whether an amplitude of the bioelectrical signal subsequently is equal to or greater than the switch threshold. In response to determining that the bioelectrical signal is greater than the switch threshold, the processor triggers the user interface device with a switch signal.
