What if the touchscreen of your smartphone or tablet could touch you back? What if the touch was as integrated into our ubiquitous technology as sight and sound?
The answer is Haptic technology . Yeah, the scientist is working on a technology that literally give you the feel of a touch thus it is a leap forward in virtual reality.
Let us understand how some of the haptic equipment works :
The PHANTOM interface from SensAble Technologies was one of the first haptic systems to be sold commercially. Its success lies in its simplicity. Instead of trying to display information from many different points, this haptic device simulates touching at a single point of contact. It achieves this through a stylus which is connected to a lamp-like arm. Three small motors give force feedback to the user by exerting pressure on the stylus. So, a user can feel the elasticity of a virtual balloon or the solidity of a brick wall. He or she can also feel the texture, temperature, and weight. The stylus can be customized so that it closely resembles just about any object. For example, it can be fitted with a syringe attachment to simulate what it feels like to pierce skin and muscle when giving a shot.

Now let’s talk about how you feel the graphics and keys on your smartphone screen.
This is done piezoelectric actuators .
Piezoelectric is a material which produce voltage difference when a pressure applied to it.
For example quartz , this material is present on your analog watches.
In Greek piezo means pressure
This image depicts how haptic technology performs in your mobile.
Microsoft research center Asia is performing some methods to indulge this technology in their smartphone .
Applications of Haptic Technology
It’s not difficult to think of ways to apply haptics. Video game makers have been early adopters of passive haptics, which takes advantage of vibrating joysticks, controllers, and steering wheels to reinforce on-screen activity.
Graphical user interfaces, like those that define Windows and Mac operating environments, will also benefit greatly from haptic interactions. Imagine being able to feel graphic buttons and receive force feedback as you depress a button.
Training with haptics is becoming more and more common. For example, medical students can now perfect delicate surgical techniques on the computer, feeling what it’s like to suture blood vessels in an anastomosis or inject BOTOX into the muscle tissue of a virtual face.
Aircraft mechanics can work with complex parts and service procedures, touching everything that they see on the computer screen And soldiers can prepare for battle in a variety of ways, from learning how to defuse a bomb to operating a helicopter, tank or fighter jet in virtual combat scenarios.
Haptic technology is also widely used in teleoperation or telerobotics. In a telerobotic system, a human operator controls the movements of a robot that is located some distance away. Some teleoperated robots are limited to very simple tasks, such as aiming a camera and sending back visual images. In a more sophisticated form of teleoperation known as telepresence, the human operator has a sense of being located in the robot’s environment.
The scientist can present virtually at mars and feel the texture of the soil.
This technology is on the way just keep alive and enjoy it.
LIVE LONG AND PROSPER!
