HAPTIC INTERACTION

INTRODUCTION:

A haptic interface is a force reflecting device which allows a user to touch, feel, manipulate, create and/or alter simulated 3D objects in a virtual environment” haptic. (Adjective Grk: haptein) having to do with the sense of touch; tactile haptics = touch, tactile, force-feedback, using force/resistance, texture, heat, vibration.

PRINCIPLE BEHIND IT:

Force display technology works by using mechanical actuators to apply forces to the user. By simulating the physics of the user’s virtual world, we can compute these forces in real-time, and then send them to the actuators so that the user feels them.

POTENTIAL BENEFITS:

  •    Reduction in fatigue
  •   Increase in productivity and comfort
  •   Decreased learning times
  •  Large reductions in manipulation errors.

Device turns computer into means for touching virtual objects

Like a high-tech version of a child’s interactive “touch and feel” book, this computer interface lets users feel a virtual object to learn its shape, and whether it’s rough as sandpaper, hard as rock or hot as fire. Plenty, if you’re in the business of creating new ways for humans and computers to interact. One of the stickiest problems in developing advanced human-computer interfaces is finding a way to simulate touch. Without it, virtual reality isn’t very real.

Now a group of researchers at MIT‘s Artificial Intelligence Laboratory have found a way to communicate the tactile sense of a virtual object — its shape, texture, temperature, weight and rigidity — and let the user change those characteristics through a device called the PHANToM haptic interface
