Abstract

An exploration of vibration during interaction with polarized texture G. Evreinov & R. Raisamo Department of Computer and Information Sciences, University of Tampere, Finland Abstract As vibration signals take place when a finger or stick rubs over the material they can be recorded through a single piezoelectric transducer. Diverse textures produce different sound patterns depending on density and gradient of texture elements as well as on friction force and relative speed of motion between stick and surface. Vibration patterns of arbitrary gestures along a texture have the specific envelope. These signals and their combinations could be used for data input, user authentication or to add new functions in conventional input devices like a mouse or keyboard. We have explored the ribbed textures similar to the dieaction grid. The 'vertical' and 'horizontal' components of the vibration frequency had difference in two times when: the step between ribs was 0.06 rnm, the slope angle of the ribbed tex
