A System for Generating Musical Score Indicating the Hitting Hand for Drum Performance
On playing drums, it is important to master the correct stroking order. Drummers are required to learn the drum rudiment to
play drums efficiently. Generally, musical scores for drums do not have the annotation that indicates which hand drummers
use to stroke each drum, left or right. Although drum teachers handwrite such annotation on the musical score, there is not
the system that generates the musical score indicating the hitting hand on playing drums automatically. In this research,
we proposed the system that generates the musical score that indicates the hitting hand to stroke each drum. The proposed
system recognizes the hitting hand on the basis of the data of a gyro sensor that are embedded in the drum sticks and MIDI
message from an electronic drum. We constructed the prototype system and evaluated its effectiveness
A method to control LED blinking for position detection of devices on conductive clothes
Various wearable computing devices face problems with their power supplies, communication channels, and placement. Conductive clothes can resolve these problems, but it is still difficult to know the positions of devices on the conductive fabric. Therefore, we have devised a method to detect the positions of such devices by using a camera. To detect the positions our method blinks the LEDs on the devices according to their ID. Additionally, we propose several methods to shorten the time for detection. An experimental evaluation confirmed that compared with conventional method our methods reduce the time to detect the positions of the devices. © 2011 ACM
