Zero Shutter Camera

Zero Shutter Camera is a native Google Glass application that triggers a camera snapshot at special moments for the wearer by continuously monitoring the wearer's physiological state over a Bluetooth connection.

Prototype concept and implementation

Zero Shutter Camera is a prototype to show a potential of using wearer’s physiological signals as inputs. (This work was presented at ACM UIST 2014.)
