Exploratory Procedures

Exploratory procedures are stereotyped movement patterns that people use when examining objects through touch to identify specific properties. Defined by Lederman and Klatzky in tactile perception research, these are hand and finger configurations that do not correspond to random gestures but are systematically associated with perceiving particular object attributes. For example, people perform lateral motion (rubbing) to assess texture, static contact to sense temperature, and enclosure (grasping) to judge shape and volume. Understanding exploratory procedures is important for designing tactile accessibility tools such as interactive 3D printed models and tactile graphics, as these natural behaviors must be accommodated and distinguished from intentional interactive gestures.
