The Laser Aura: a prosthesis for emotional expression


We are studying the use of a 'laser aura' as a (wearable) prosthesis for enhanced emotional expression. The goal of such wearable display is to externalize subtle psycho-physiological states of the user by projecting minimalistic imagery in the immediate surrounding for others to see. In the present configuration, a 'laser aura' or 'laser halo' change its shape and dynamic behavior as a function of the user stress. Such iconic imagery (inspired by manga graphical representations) may give others an instant cue about the person psychological state (and thus function as the equivalent of online availability status in the real world). It may as well function as a biofeedback device, and help regain control of one's own body in stressful situations.
