Multimodal Biosensing

Different measurement modalities have complementary tradeoffs in detail, speed, and spatial precision. Multimodal biosensing is promising but technically difficult because interpreting many signals and acting within milliseconds remains unresolved. Multimodal biosensing measures many physiological signals at once to infer user state more richly than a single sensor could. Candidate biosensing signals include brain activity, eye data, heart activity, skin response, respiration, and blood-flow measures. Multimodal biosensing aims to estimate state variables such as stress, mood, vigilance, arousal, awareness, and attention rather than decode specific thoughts.
