Playin’ around with surround sound

Documentation for pan n’ tilt prototype. This setup allows the participant to control the movement and dispersal of sound in the room using the gyroscope. Each of the four corners of the gyroscope correspond to each of the four speakers in the room. The effect is immediate; for example, tilting the top right corner of the gyroscope downwards will increase the volume of the ‘front-right’ speaker (position when the participant faces the screen projection).

The accompanying graphics on the screen are a visual representation of the sound dispersal. The free-flowing polygon has 4 corners which correspond to the 4 speakers in each corner of the room. Tilting the gyroscope in one corner will alter the shape of the polygon and stretch it furthest in the same direction of the speaker. Conversely, keeping the gyroscope leveled will produce equal volume in all 4 speakers and the polygon will become a rectangle shape.

3D graphics and a more balanced sound increment (using the table object) could be applied for the next iteration of this prototype to enhance the experience.
