A4.13
Texture and material perception
Cards in this group · 4
- A4.13.1Texture perception depends on relative motion between finger and surface; static contact resolves little
- A4.13.2Fine texture is coded mainly through the vibratory channel, coarse texture mainly through spatial pressure distribution
- A4.13.3Scanning speed changes vibration frequency, so the same texture feels different at different speeds
- A4.13.4Touchscreens simulate texture with local friction or vibration — both are indirect encodings, not literal reproduction
