Abstract

This paper describes a study that investigates tilt-gesture depth on a Bluetooth handheld music controller for activating and deactivating music loops. Making use of a Wii Remote's 3-axis ADXL330 accelerometer, a Max patch was programmed to receive, handle, and store incoming accelerometer data. Each loop corresponded to the front, back, left and right tilt-gesture direction, with each gesture motion triggering a loop 'On' or 'Off' depending on its playback status. The study comprised 40 undergraduate students interacting with the prototype controller for a duration of 5 minutes per person. Each participant performed three full cycles beginning with the front gesture direction and moving clockwise. This corresponded to a total of 24 trigger motions per participant. Raw data associated with tilt-gesture motion depth was scaled, analyzed and graphed. Results show significant differences between each gesture direction in terms of tilt-gesture depth, as well as issues with noise for left/right gesture motion due to dependency on Roll and Yaw values. Front and Left tilt-gesture depths displayed significantly higher threshold levels compared to the Back and Right axes. Front and Left tilt-gesture thresholds therefore allow the device to easily differentiate between intentional sample triggering and general device handling, while this is more difficult for Back and Left directions. Future work will include finding an alternative method for evaluating intentional tilt-gesture triggering on the Back and Left axes, as well as utilizing two 2-axis accelerometers to garner clean data from the Left and Right axes.
