Introduction to haptics

Haptic, is the term derived from the Greek

word, haptikos, which means ’the sense of touch’.

Haptic feedback

• Tactile feedback• Force feedback

Basic idea behind haptics

• Haptic is the technology of adding sensation of touch and feelings to computer

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

Classification of haptics

How technology works

Haptic devices

• 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.

• Some of haptic devices are….

Cyber glove

• It allows users to touch, feel and manipulate • 3-D objects in virtual environments.

Phantom device

PHANTOM® interface

from Sensable Technologies

Haptic applications

• Medical• Gallery exhibition• Tele presence• Gaming

In medical surgical training

In gallery exhibition

In gaming

Tele presence

Research on future haptic application

• Future applications of haptic technology cover a wide spectrum of human interaction with technology. 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.[The medical industry stands to gain from virtual and telepresence surgeries, which provide new options for medical care. The clothing retail industry could gain from haptic technology by allowing users to "feel" the texture of clothes for sale on the internet. Future advancements in haptic technology may create new industries that were previously not feasible or realistic.

Advantages

• Communication is centered through touch and the digital world can behave like the real world.

• Medical field simulators allow would be surgeons to practice digitally, gaining confidence in the procedure before working on breathing patients.

• With haptic hardware and software, the designer can maneuver the part and feel the result, as if he/she were handling the physical object.

Technology downsides

• Haptics applications can be extremely complex, requiring highly specialized hardware and considerable processing power.

• The complexity also means that many haptics projects rely on fixed installations of equipment and are not easily portable.

• The precision of touch requires a lot of advance design.

conclusion

• We finally conclude that Haptic Technology is the only solution which provides high range of interaction that cannot be provided by BMI or virtual reality. Whatever the technology we can employ, touch access is important till now. But, haptic technology has totally changed this trend. We are sure that this technology will make the future world as a sensible one.
