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. The present disclosure illustrates various techniques and configurations to enable a series of dynamic workflows for the selection and presentation of content from an information system relevant to activities of a human user. The dynamic workflows used with the NeuroNode…
