Haptic is the “science of applying tactile sensation to human interaction with computers”. The sensation of touch is the brains most effective learning mechanism –more effective than seeing or hearing –which is why the new technology holds so much promise as a teaching tool. With this technology we can now sit down at a computer terminal and touch objects that exists on “mind” of the computer. By using special input/output devices (joysticks, data gloves or other devices),users can receive feedback from computer applications in the form of felt sensations in the hand or other parts of the body. In combination with a visual display, Haptic technology can be used to train people for tasks requiring hand- eye coordinatio , such as surgery and spaceship maneuvers. In our paper we have discussed the basic concepts behind haptics along with the haptic devices and how these devices are interacted to produce sense of touch and force feedback mechanisms. Then, we move on to a few applications of Haptic Technology. Finally we conclude by mentioning a few future developments. Introduction:
Haptic technology, or haptics, is a tactile feedback technology which takes advantage of the sense of touch by applying forces,vibrations or motions to the user.This mechanical stimulation can be used to assist in the creation of virtual objects in a computer simulation, to control such virtual objects, and to enhance the remote control of machines and devices (telerobotics). It has been
described as "doing for the sense of touch what computer graphics does for vision". Haptic devices may incorporate tactile sensors that measure forces exerted by the user on the interface. 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. These objects are used to systematically probe human haptic capabilities, which would otherwise be difficult to achieve. These research tools contribute to the understanding of how touch and its underlying brain functions work. The word haptic, from the Greek ἅπτικός (haptikos), means pertaining to the sense of touch and comes from the Greek verb ἅπτεσθαιhaptesthai, meaning to contact or to touch. WHAT IS HAPTICS??
Haptics is Quite Literally The Science of Touch.
The origin of the word haptics is the Greek haptikos, meaning able to grasp or perceive. Haptic sensations are created in consumer devices by actuators, or motors, which create a vibration. Those vibrations are managed and controlled by embedded software, and integrated into device user interfaces and applications via the embedded control software APIs. You’ve probably experienced haptics in many of the consumer devices that you use every day. The
rumble effect in your console game controller and the reassuring touch vibration you receive on your smartphone dial pad are both examples of haptic effects. In the world of mobile devices, computers, consumer electronics, and digital devices and controls, meaningful haptic information is frequently limited or missing. For example, when dialing a number or entering text on a conventional touchscreen without haptics, users have no sense of whether they’ve successfully completed a task.With Immersion’s haptic technology, users feel the vibrating force or resistance as they push a virtual button, scroll through a list or encounter the end of a menu. In a video or mobile game with haptics, users can feel the...
