Abstract
Active touch sensing: finger tips, whiskers, and antennae
Highlights
Active touch can be described as the control of the position and movement of tactile sensing systems by reaching out and exploring—sensing by “touching” as opposed to being touched
Ackerley et al (2012), demonstrated using fMRI that different brain areas are functional in active touch tasks compared to passive touch ones
The whisker, or vibrissal, system of small mammals is an important model of active touch sensing
Summary
Active touch can be described as the control of the position and movement of tactile sensing systems by reaching out and exploring—sensing by “touching” as opposed to being touched. The first section of articles covers various aspects of human touch. As with all active touch systems, humans move their fingertips through a sequence of exploratory movements that yields the most information from the task. These movements depend on both the task in hand and prior experience.
