Haptic (hap'tik) :
– adj.[Gr. haptein, to touch + ic]
– of, or having to do with, the sense of touch.

– You can both transmit and receive information
simultaneously
• Touch is a complex modality consisting of
several distinct sensory channels
– Skin, muscles, balance, orientation, pressure,
temperature, pain……
• Complexity leads to misunderstandings
The Sense of Touch in Computing
• Relatively unused in mainstream computing
– Implicitly – keyboards keys, casing of mouse….
– Explicitly – programmable touch
• Beginning to change - devices are emerging
– History – teleoperation devices
– New devices – cheaper, smaller, better…
• Haptics is a complex modality
– Better understanding required through research
– Confusing terminology clouds matters
Terminology
• Haptic
– Relating to the sense of touch.
• Kinaesthetic
– Meaning the feeling of motion. Relating to sensations
originating in muscles, tendons and joints.
• Tactile
