Explanation
A wearable hand device that transmits virtual touch sensations.
Real-world example
Feeling the rough texture of a virtual wall through a specialized glove.
Practical applications
- Touch simulation: feeling the shape, texture, and hardness of virtual objects
- Finger resistance: sensation of gripping a solid object
- Fine motor training: learning precise manipulations
- Rehabilitation: motor exercises with tactile feedback
Types of haptic gloves
Vibration gloves
- Vibrating motors on the fingers and palm
- Simple but effective feedback
- Moderate cost (a few hundred euros)
Example: bHaptics TactGlove
Force feedback gloves
- Exoskeleton that blocks finger movement
- Sensation of gripping a solid object
- High cost (several thousand euros)
Example: HaptX Gloves, SenseGlove
VR scenario
A surgeon practices a suturing technique in VR. Thanks to haptic gloves, they feel the resistance of the thread, the tension of the tissue, and the "click" when the knot is properly secured. This tactile memory transfers to the operating room.
Why it matters in professional VR
- Haptic gloves fill the missing link in VR: the sense of touch
- Essential for training where manual sensation is critical
- A rapidly evolving market: costs are dropping and precision is increasing
