HAIR: HAptic feedback with a mobile AIR jet

Abstract

Haptic devices are dedicated to render virtual tactile stimulation. A limitation of these devices is the intrusiveness of their mechanical structures, i.e. the user need to hold or wear the device to interact with the environment. Here, we propose a concept of new tactile device named HAIR. The device is composed of a computer vision system, a mechatronic device and air jets that stimulate the skin. We designed a first prototype and conducted a preliminary experiment to validate our concept. The interface enables a tactile interaction without using physical contact with material devices, providing better freedom of movement and enhancing the interaction transparency.

A bilateral rehabilitation method for arm coordination and manipulation function with gesture and haptic interfaces

“…Some other haptic interfaces are more focus on transparency, which can be adapted for rehabilitation in a promising way [18]. In this paper, a bilateral arm rehabilitation method has been designed for training therapy of patients with motor dysfunction, specially focusing on the cooperation of upper limbs and dexterous manipulation of the impaired hand.…”

Evaluating Ultrasonic Tactile Feedback Stimuli

“…Tactile sensations can be rendered to interactive spaces in 3D. Technologies such as pressurized air jets [16] or air vortex rings [18] can provide strong but rough feedback with some inherent time lag. Lasers [8,11] or electric arcs [17] are possible for very precise short range feedback.…”

Sampling Strategy for Ultrasonic Mid-Air Haptics

“…Researchers adopt different technologies and methods to develop mid-air tactile displays. One approach is to use pressurised air to convey tactile stimuli either in the form of air jets [28] or air-vortices [24]. This approach does not allow for multi-points stimulus.…”

“…Mid-air haptics is a growing field which aims to move the interaction from touch surfaces to touchless interactive spaces in 3D. Hence technologies such as air-jet [28], air-vortexes [24], laser [12,22], electric arc [25], and ultrasonic-phased array [3,7] were developed to provide mid-air tactile feedback to the user, without requiring augmentation with extra wearables. Among those technologies, ultrasonic phased arrays are particularly proficient at rendering a range of complex tactile patterns on the user's palm or fingertips.…”
