Evaluating a mobile spontaneous eye blink tracker for use in tele-presence HRI as a low bandwidth social communicative cue

Research suggests that the rate at which humans spontaneously blink their eyes over time is strongly related to their underlying cognitive state. The ability to present the real time blinking behaviour of a human teleoperator via a robot proxy therefore potentially offers observers a low bandwidth - yet salient - cue as to the cognitive state of the teleoperator.
