They obey hand gestures
Ever thought you could flip channels on the TV with a hand clap or move documents on a computer monitor with hand gestures? All this is possible now.
HAVE you ever imagined how life would be without your good ol’ keyboard? Well, the familiar keyboard and mouse method of interacting with your PC could soon be a thing of the past. Researchers have now developed a novel way of using a computer that uses hand gestures. In gesture recognition technology, a camera reads the movements of the human body and communicates the data to a PC that uses the gestures as input to control devices or applications. Jaspreet Bindra of Microsoft India says, “It is but natural that our interaction with computers will move more and more towards voice recognition and gestures, they will be able to read facial expressions and become more intuitive. Essentially, the way we interact with computers stands to change dramatically, and the day we communicate with them just as we do with other human beings is no longer the substance of science fiction.”
Prashanth Adiraju of Intel concurs. “Over the next few years, tremendous changes will be unleashed and this will drive a whole new way in which we interact with computers. Physical keyboards could disappear, as gesture recognition technology allows messages to be typed in thin air — virtual keys get projected in front of you.”
No remote control
TV viewers would no longer need a remote control to flick through the channels. A TV system from JVC can change channels or turn off and on by listening for particular sounds, such as a handclap. Hitachi TVs in Japan let people turn on their screens, scan through channels and change the volume on their sets with hand motions.
Gesture technology could also be used as a next generation control system for video gaming. Nintendo’s Wii console’s motion-sensitive controller allows players to act on the screen by waving the pad around. Kinect has brought a magic to gaming as it is the incarnation of a new generation of natural user interfaces. The Razer Hydra lets you extend your natural body motion directly into the game. Taiwanese researchers have come up with a lock that can be opened with gestures.
After hour sales
Fraunhofer Heinrich Hertz Institute has developed a large monitor wired to motion-tracking technology. When window shoppers point to the item of their interest, accompanying information will be displayed on the monitor.
Gesture technology could also help the physically disabled, enabling them to interact with a computer without a mouse and keyboard. It could also help people suffering from repetitive strain injury.
Drive safely
Using this technology, drivers could operate their car radios and navigators easily. It can also offer safety benefits, since commands can be made without taking the driver’s eyes off the road. Researchers are investigating multimodal interfaces for scenarios involving multiple co-present users interacting with large vertical 2D or 3D displays from a distance. Sriganesh Madhvanath of HP Labs India says, “A simple example of this in the home environment is photo sharing on a TV, where one or more users may walk through a collection of their vacation pictures with friends or family members. ”
