Human Recognition Performance of Simple Spatial Vibrotactile Patterns on the Torso
IEEE World Haptics Conference (IEEE WHC), 2023 · pp. 20–27
At a glance
Which simple spatial patterns remain distinguishable when several torso actuators vibrate together?
Investigating which simultaneous vibration patterns people can recognize on the torso, toward a practical vocabulary for haptic vests.
The approach
Sixteen on/off patterns are tested in front, back, and horizontal torso configurations. The study compares recognition across layouts and numbers of active motors.
Key takeaways
High overall recognition
Recognition accuracy exceeds 91%, with performance varying by the number of active vibrations.
A measurable tactile vocabulary
Estimated information transfer is 3.48–3.66 bits, equivalent to roughly 11–12 perfectly distinguishable patterns.
Patterns grounded in perception
The results inform sets of distinguishable patterns for torso-based communication through haptic vests.
