Haptic feedback in VR aims to simulate the sense of touch and allow users to interact with virtual objects as if they were real.

Electromagnetic actuators, piezoelectric actuators, and shape-memory alloys are all widely used technologies for haptic feedback in VR.

Designing haptic feedback systems for VR involves addressing multiple challenges, including size and weight constraints, accurate simulation of touch, and minimizing latency.

VR haptic feedback has potential applications in various domains, including medical training, gaming, and remote collaboration.

Haptic illusion refers to the phenomenon where users perceive virtual objects as having physical properties and can interact with them as if they were real.

Achieving a realistic haptic experience in VR requires a combination of high-resolution actuators, accurate modeling of virtual objects, and minimizing latency.

Current VR haptic feedback technologies face challenges such as high cost, limited range of sensations, and difficulty in creating realistic experiences for all users.

Researchers are actively exploring various areas to advance VR haptic feedback, including soft robotics, brain-computer interfaces, and ultrasound haptics.

Mid-air haptics refers to the technology that enables users to perceive haptic sensations without direct physical contact with virtual objects.

HaptX Gloves are a VR haptic feedback device that utilizes electromagnetic actuators to provide users with a sense of touch and physical interaction in virtual environments.

Haptic-visual conflict refers to the situation where users perceive a discrepancy between what they see and what they feel in VR, leading to discomfort and a diminished sense of presence.

TeslaSuit is a VR haptic feedback device that employs shape-memory alloys to generate tactile sensations and provide users with a sense of physical interaction in virtual environments.

Electrotactile haptics refers to the technology that utilizes electrical signals to stimulate the skin and create tactile sensations, allowing users to perceive virtual objects without physical contact.

SenseGlove Nova is a VR haptic feedback device that utilizes piezoelectric actuators to provide users with tactile sensations and enable them to interact with virtual objects as if they were real.

Airborne haptics refers to the technology that utilizes pressure waves in the air to create tactile sensations, enabling users to perceive virtual objects without physical contact.
