With change in technology, everything around us has changed.
Size of computers, memory, display everything has changed. Now computers are
made in touch screen modes. With so many changes in technology, Computer mouse
will be dead after some time. We are limited to two-dimensional movements but
now researchers in US have developed the 3D touch.
It is a ‘thimble’ like device that sits on the end of your
finger and enables you to interact with virtual world in three-dimensional
fashion. This intelligent device interacts with computer and sensing its
position accurately in three-dimensions. The device uses three types of
sensors, a 3D accelerometer, a 3D magnetometer, and a 3D gyroscope to perform
its task. This combination of sensors allows the data from each sensor to
compared and combined to produce a far more precise estimate of orientation
than a single measurement alone. The 3D touch has an optical flow sensor that
measures the movement of device against a two-dimensional surface.
The device works by responding a set of programmed mouse like
gestures, like selecting and dragging, finger tap, and click. These gestures
allow the user to interact with objects in three-dimensions within the
interface of the computer. A wire to an Arduino controller, which combines the
data from all sensors and is then streamed to a laptop, connects the device. The
team is now looking into taking the device from wired to wireless.
It will be small, unobtrusive, and easily portable. It will
also work with existing devices like desktop PC, laptops. Along with this if,
you have two devices then it can be worn on each hand to enable ‘multitouch’
interaction. Nguyen and Banic from the University of Wyoming in US have created
this 3D touch device.
