The sense of touch

Overview of the experimental setup for tactile detection in a granular substrate. (a) Human experimental setup, showing a participant's finger scooping sand into a box filled with sand, with an LED strip guiding the path of movement and a cube buried in fixed positions. (b) Robotic experimental setup, including a UR5 arm with a tactile sensor and a cube buried in sand. (c) Schematic diagram of the scooping process. Credit: Queen Mary University of London.

New study: Humans are capable of “remote touch” and identify objects buried in sand before contact

Experiments indicate higher-than-expected tactile sensitivity; humans achieved 70.7% accuracy, and researchers see potential for robotics, assistive technologies, and searching in limited visibility conditions
