Haptic technology is like exploring the virtual world with a stick. The computer communicates sensations through a haptic interface –a stick, scalpel, racket or pen that is connected to a force-exerting motor. In combination with a visual display, haptics technology can be used to train people for tasks requiring hand-eye coordination, such as surgery and space ship maneuvers.

Haptic technology
- 3. Introduction Haptic technology, or haptic, is a tactile feedback technology which takes advantage of the sense of touch by applying forces, vibrations, or motions to the user. Haptic technology has made it possible to investigate how the human sense of touch works by allowing the creation of carefully controlled haptic virtual objects.
- 4. Design Haptics are enabled by actuators that apply forces to the skin for touch feedback, and controllers. The actuator provides mechanical motion in response to an electrical stimulus.
- 5. Commercial Application • In 2008, Apple's MacBook and MacBook Pro started incorporating a "Tactile Touchpad" design with button functionality and haptic feedback incorporated into the tracking surface. • Tactile haptic feedback is becoming common in cellular devices.
- 6. Haptic technology in Game • Haptic feedback is commonly used in arcade games, especially racing video games. In 1976, Sega's motorbike game Moto-Cross, also known as Fonz, was the first game to use haptic feedback which caused the handlebars to vibrate during a collision with another vehicle. • In 2007, Novint released the Falcon, the first consumer 3D touch device with high resolution three- dimensional force feedback; this allowed the haptic simulation of objects, textures, recoil, momentum, and the physical presence of objects in games.
- 7. Arts and Design Touching is not limited to feeling, but allows interactivity in real-time with virtual objects. Haptic are used in virtual arts, such as sound synthesis or graphic design and animation. The haptic device allows the artist to have direct contact with a virtual instrument that produces real- time sound or images.
- 8. Haptic in Robotics • The Shadow Hand uses the sense of touch, pressure, and position to reproduce the strength, delicacy, and complexity of the human grip. • The first PHANTOM, which allows one to interact with objects in virtual reality through touch, was developed by Thomas Massie while a student of Ken Salisbury at MIT.
- 9. Future Applications Current research focuses on the mastery of tactile interaction with holograms and distant objects, which if successful may result in applications and advancements in gaming, movies, manufacturing, medical, and other industries. Future advancements in haptic technology may create new industries that were previously not feasible or realistic.
- 10. Holographic Interaction Researchers at the University of Tokyo are working on adding haptic feedback to holographic projections. The research uses ultrasound waves to create acoustic radiation pressure, which provides tactile feedback as users interact with the holographic object.
- 11. Medical Applications • As of 2003, researchers at Stanford University were developing technology to simulate surgery for training purposes. Simulated operations allow surgeons and surgical students to practice and train more. Haptic technology aids in the simulation by creating a realistic environment of touch. • The researchers, led by J. Kenneth Salisbury Jr., professor of computer science and surgery, hope to be able to create realistic internal organs for the simulated surgeries.
- 12. Conclusion Advances in hardware will provide opportunities to produce haptic devices in smaller packages, and haptic technology will find its way into increasingly common place tools.
