Basic idea Basic idea

Haptics, is the technology of adding the sensation of touch and feeling to computers.

A haptic device gives people a sense of touch with computer-generated environments, so that when virtual objects are touched, they seem real and tangible.

Understanding and enabling a compelling experience of Presence not limited to "being there", but extended to "being in touch" with remote or virtual surroundings.

• Common interface devices like mouse and joystick are only input devices. No feedback.

• Haptic devices are input-output devices.

Conclusion Conclusion

The next important step towards realistically simulated environments that have been envisioned by science fiction authors.Large potential for applications in critical fields as well as for leisurely pleasures. Haptic devices must be smaller so that they are lighter, simpler and easier to use.
