A phone vibrates in your hand. A shirt seam fades from awareness. A mug feels warm, then ordinary. Touch is not one sense but a coordinated system for pressure, texture, vibration, temperature, pain, itch, movement, and body position.
How Touch Works is a no-background guide to somatosensation for curious teens and adults. It follows everyday contact from skin mechanics and specialized receptors through nerves, spinal pathways, body maps, prediction, action, social context, and haptic technology without equations or health promises.
- Trace tactile events from physical change to signal, perception, action, and meaning.
- Understand pressure, texture, vibration, temperature, nociception, pain, itch, proprioception, and body maps.
- See how active exploration, expectation, context, consent, accessibility, prosthetics, and digital haptics shape touch.
- Use 54 black-and-white diagrams designed for print readability.
- Try optional, low-risk observations that are not tests, diagnosis, or treatment.
For self-study, homeschool enrichment, parent-teen reading, introductory neuroscience curiosity, accessibility and design interest, and readers following the six-volume sense series.
