Haptic refers to technology that uses touch to control and interact with computers. A user may apply a sense of touch through vibrations, motion or force. Haptic technology is used mainly in creating virtual objects, controlling virtual objects or in the improvement of the remote control of machines and devices. The word haptic is derived from the Greek "haptikos," which means a sense of touch.
Haptic devices can measure reactive forces and bulk forces applied by a user.
The first use of a haptic device was in large modern aircraft that relied on servomechanism systems to operate control systems. Haptic technology can also be used to study the human sense of touch by enabling the creation of controlled virtual objects, which can be used to consistently investigate human haptic capabilities that are otherwise difficult to study.
Haptic technology is applied in the following fields:
- Teleoperation: Remote-controlled robotic tools that enable human operators to control remote or distant environments. Remote-controlled robotic tools, such as those used for dangerous tasks, are a standard example of this type of technology.
- Virtual Environments: Haptics are becoming very popular as an imperative part of virtual reality systems. Examples include simulators, control systems, devices and specialized models that allow for touch-based interaction with computers.
- Robotics: Robots manipulate the environment by relaying information to a central computer for processing and analysis.
- Cellular Devices: Haptic technology is gaining popularity in the mobile consumer technology field, where it is used to provide features such as vibration feedback on smartphone touch screens.
- Future Applications: Currently researchers are focusing on controlling and mastering tactile interaction with holograms and distant objects. If this research is successful it may result in applications and advancements in the field of gaming, movies, manufacturing, medical and other industries
