A multimodal haptic device for rendering cutaneous and kinesthetic tactile cues of a target, and method for rendering cutaneous and kinesthetic tactile cues of a target

2025

Abstract

A multimodal haptic device for rendering cutaneous and kinesthetic tactile cues of a target, including an actuator configured to contact a body part; a support movable unit, to move the actuator in one or an opposite direction of a force, the actuator including a contact region, configured to receive the force, and an adaptive region, around the contact region and substantially flat at rest; a controller configured to: set a first actuation input to raise the adaptive region relative to the contact region, wherein, in use, the haptic softness tactile cue is rendered by a surface of the raised adaptive region contacting the body part; drive the support movable unit to move the actuator in the one or opposite direction, the haptic kinesthetic tactile cue of the target rendered by another force applied to the body part by the actuator in the opposite direction.

Actuator

An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a "mover". An actuator requires a control device (controlled by control signal) and a source of energy. The control signal is relatively low energy and may be electric voltage or current, pneumatic, or hydraulic fluid pressure, or even human power. Its main energy source may be an electric current, hydraulic pressure, or pneumatic pressure.

Proxemics

Proxemics is the study of human use of space and the effects that population density has on behavior, communication, and social interaction. Proxemics is one among several subcategories in the study of nonverbal communication, including haptics (touch), kinesics (body movement), vocalics (paralanguage), and chronemics (structure of time). Edward T. Hall, the cultural anthropologist who coined the term in 1963, defined proxemics as "the interrelated observations and theories of humans use of space as a specialized elaboration of culture".

Force

In physics, a force is an influence that can cause an object to change its velocity, i.e., to accelerate, unless counterbalanced by other forces. The concept of force makes the everyday notion of pushing or pulling mathematically precise. Because the magnitude and direction of a force are both important, force is a vector quantity. It is measured in the SI unit of newton (N) and often represented by the symbol F.
