you're at the park, it's a beautiful day the light is shimmering off the lake. if we outfit you with one or two electromagnetic sensors (in a headband for example) to what extent can we describe the way you feel in that moment? using neural signals and/or signals generated by muscular activity? can we communicate your state to other people?
to what extent can we infer mental and physical states from sensor data? what kinds of applications might leverage the real-time transmission of psychophysical states?
