A system includes a processor in communication with a set of bioelectrical sensors and a user interface device that monitors bioelectrical signals from a set of bioelectrical electrodes. Processor automatically adjusts one of: (i) a resting threshold； and (ii) a switch threshold that is greater than the resting threshold based 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. If so, the processor determines whether an amplitude of the bioelectrical signal subsequently is equal to or greater than the switch threshold. In response to detern1ining that the bioelectrical signal is greater than the s.vitch 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 infom1ation system relevant to activities of a human user.
