Identifying Virtual 3D Geometric Shapes with a Vibrotactile Glove

Abstract

The emergence of off-screen interaction devices is bringing the field of virtual reality to a broad range of applications where virtual objects can be manipulated without the use of traditional peripherals. However, to facilitate object interaction, other stimuli such as haptic feedback are necessary to improve the user experience. To enable the identification of virtual 3D objects without visual feedback, a haptic display based on a vibrotactile glove and multiple points of contact gives users an enhanced sensation of touching a virtual object with their hands. Experimental results demonstrate the capacity of this technology in practical applications.

A Modular Transradial Bypass Socket for Surface Myoelectric Prosthetic Control in Non-Amputees

“…Using a multichannel array for sEMG requires more surface area, but provides more signals that can be used to provide intuitive control of a high-degree-of-freedom prosthesis. Another consideration is the ability to perform sensorimotor integration experimentation, where the intact hand must be accessible for providing various forms of noninvasive vibrotactile or electrotactile substituted sensory feedback [17], [23], [24]. For these reasons, a bypass socket should preserve as much access to the intact limb as possible.…”

SwarmTouch: Guiding a Swarm of Micro-Quadrotors With Impedance Control Using a Wearable Tactile Interface

“…force vector, vibration, and contact state [19]. However, vibration motors, which are easy to control, are widely applied in Virtual Reality [20], [21]. We applied eccentric rotating mass (ERM) vibration motors which deliver the dynamic state of the swarm in the form of tactile patterns.…”

Need for Touch in Human Space Exploration: Towards the Design of a Morphing Haptic Glove – ExoSkin

“…These gloves, embedded with multiple sensors and trackers, have been mainly used for applications involving object selection and manipulation in virtual environments. Some of these glove-based systems also have actuators mounted to provide haptic feedback to the user's hands [5,22,32].…”

“…Nevertheless, due to their complexity, not all technologies have been exploited in glove designs. Vibration actuators are most common as they are small and lightweight [5,22]. The Teletact and Teletact II gloves [32] use air pressurized bladders to create force feedback in the palm.…”

“…The second type uses vibration actuators and has been implemented not only in glove-based systems but many other prototype devices [2]. Although vibrations generate a 'buzzing' sensation, they can be used to produce different textures [21] and even 3D shapes [22]. The third method of producing tactile sensations is by creating lateral skin deformation using a simple comb-like system [10,20].…”
