Haptic technology

The term Force Feedback (English; haptic technology in the English language or haptics, ie haptic technology) or force feedback means a used in input devices for computer feedback of force to the user.

In control systems

The principle of force feedback is used in some equipped with fly- by-wire aircraft, since there is no direct transfer of force from the control surfaces of the aircraft to the controls of the pilot and thus important, tangible information for the pilot to be produced artificially. In the haptic mediation of physical characteristics of the controlled object in the control element is called an active actuator part.

Also gripping arms / manipulators of remote-controlled submersible robot (Remotely Operated Vehicle ) are partly provided with Force Feedback. The mechanical feedback of force on the operated by the pilot master arm more precise control is made possible. The technique is still very prone to error and requires further development.

Force feedback is already used in the automotive field, for example, how to use the iDrive from BMW or force feedback gas pedal Continental Temic.

In the computer simulation,

Force - feedback systems are used as man-machine interface versatile use in industry and science. One application is the remote control of robots with force feedback, so that the operator can feel the touch of time and avoids damage. Application is, for example, the remote control of robots in the nuclear industry, especially for repairs, dismantling old reactors for contaminated areas and disposal of radioactive material. Another application is the remote control of robots with repair work in space, for example at the International Space Station.

In medical Force Feedback is particularly on training simulators for training in the clinical field use. Rehabilitation and robot-assisted surgery systems to support medical professionals are more applications.

In the field of virtual reality technology is used to support installation, testing and virtual training in the development and planning of scale models.

In computer games

Some hardware of computer games can give the player a mechanical feedback on events in the game. The input device vibrates for example in clashes or the firing of weapons. Also increasing the resistance to movement of the input device in specific directions, depending on the situation is possible.

Most are vibration patterns for different game situations available to produce a realistic impression. One in a racing game colliding with a wall car can eg a short, sudden jerk or produce in a long curve, a constant centering force, while the fire a fully automatic firearm can be loaded in a first-person shooter with persistent vibrations.

The first game took advantage of the stationary 1986 arcade game Out Run the Force Feedback for mechanical feedback through the steering wheel. Later this was introduced for game consoles, such as with controllers for the PlayStation or the Rumble Pak by Nintendo.
