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
