VR Drums

by Chihiro SAKAI

ABSTRACT

The user can beat the drum set in the CG space by moving the drumsticks in the real world. The real-world drumsticks are equipped with accelerometers, which can detect tilt in three directions each in roll, pitch and yaw.Feature point of it is only using accelerometers to achieve a portable system. Motion capture system isn’t used in this system, so drum set type selection is determined by the angle of the sticks. Also, whether the drum set is beaten or not is determined by acceleration.

IMPLEMENT

When the user swings the drumsticks within a specific area, the drum set specified for that area is sounded and the color of the drum set in the CG space changes. The drum set area is specified by the yaw and pitch angles. In the diagram below, when the yaw angle exceeds 50 degrees, the drumstick enters the region where the sound is played. And , the same mechanism is used for the pitch angle, showing an example where the sound is played when the pitch angle exceeds 30 degrees.
