Sensors for Interaction

List of Sensors suitable for Interaction, categorized by different aspects:


Interface:

Resistance, voltage, current, capacitance, frequency, digital protocol, pwm, switch, open collector, logic level

Physical effect:

Pressure, Tension, Voltage, Current, Magnetism, Bend / flex, position, length, distance, presence, orientation, light, conductance (resistance), sound pressure, air pressure, fluid pressure, ultrasound, angle, radii (curvature)

Use as interface

Difficult to classify, thus incomplete:

location (2d, 3d), eye position, movement, forces and deformation, presence, ambient measurements. switches and buttons. incremental input (rotary or linear sliders, etc.)

Common Examples

writing: location + pressure mouse: location + digital pressure + wheel
