Explanation
A hand prosthesis controlled remotely or by thought.
Real-world example
A robotic surgical hand controlled by a physician from a remote location.
Practical applications
- Teleoperation: manipulating objects remotely via a robotic hand
- Precision surgery: operating with miniature remote-controlled instruments
- Hazardous environments: handling radioactive or explosive substances
- Body extension: adding extra grasping capabilities
Applications in virtual reality
Avatar with exohand
- Controlling a robotic arm via movements in VR
- Haptic feedback from the remote hand's sensations
- Applications in industrial telepresence
Example: A technician in France repairs equipment in Japan via a robotic avatar
Exohand simulation
- Training on robotic arm manipulation
- Designing and testing control interfaces
- Training in robotic surgery
Example: Training a surgeon on Da Vinci robot procedures in VR
VR scenario
In a nuclear maintenance simulator, you wear a VR headset and control a robotic arm equipped with an exohand to manipulate fuel rods. Every movement of your real hand is replicated by the mechanical hand, and you feel the resistance and weight of the manipulated objects through haptic gloves.
Why it matters in professional VR
- Advanced telepresence: going beyond mere visualization to remote physical action
- Safety: operating in environments that are lethal to humans
- Training: learning teleoperation without risking expensive equipment
- Accessibility: enabling people with reduced mobility to perform physical tasks
