conicScape

conicScape consists of a finger ring and a color camera hooked to a color tracker.

the ring is made of silicon. placed inside is a high brightness surface mount red LED and enough power to turn it on.

the color camera constantly monitors the position of the red light emitted by the ring using a simple pattern recognition algorithm.

the algorithm approximates a circle out of the acquired frames. it calculates the radius and the centre coordinates of the circle and uses them as input to determine the user's position in the 3D space. the code is available here. for this prototype, it uses MAX/MSP/JITTER to get the input and produce the output.

the output is a simple boring sound. the closer the user is to the camera, the louder the sound, moving from left to right controls the stereo pan and going up and down changes the pitch of the sound.

further versions of coniscape should be coded as a stand alone input device using its own device drivers.
