Designing haptic interactions

A bit of Taxonomy

  • Somatosensory systems

  • Somesthetic senses:

    • sense of touch
    • proprioception
    • haptic perception
  • Haptic feedback
- Kinesthetic - Tactile

Types of tactile receptors

  • Mechanoreceptors
  • Thermoreceptors
  • Nociceptors
All sharing the same channel Gate Control Theory running cool water on a burned area = less pain

Tactile receptors

Two-point discrimination

Do we have the same tactile sensitivity everywhere?
