Such encounters are becoming increasingly difficult. With a growing number of people turning to Kindles and other electronic readers, and with the Apple iPad arriving on Saturday, it is not always possible to see what others are reading or to project your own literary tastes. You can’t tell a book by its cover if it doesn’t have one.
In computing, a pointing device gesture is a way of combining pointing device movements and clicks which the software recognizes as a specific command. Pointing device gestures can provide quick access to common functions of a program.
Gesture based computing is referred to as pointing device gesturing. In this sentence, numerous ways are provided to show the functions of this technology.
The first pointing device gesture, the "drag," was introduced by Apple to replace a dedicated "move" button on mice shipped with its Macintosh and Lisa computers.
Dragging involves holding down a pointing device button while moving the pointing device; the software interprets this as an action distinct from separate clicking and moving behaviors.
Unlike most pointing device gestures, it does not involve the tracing of any particular shape. Although the "drag" behavior has been adopted in a huge variety of software packages, few other gestures have been as successful.
A major drawback of current gesture interaction solutions is the lack of support for two necessary user interface design principles, feedback and visibility.
Devices that can accept multiple simultaneous inputs (like using two fingers on the Apple iPhone or the Microsoft Surface to zoom in or out) and gesture-based inputs like those used on the Nintendo Wii have begun to change the way we interact with computers.
The sentence briefly describes the definition of gesture based computing.
A number of mobile applications use gestures. Mover lets users flick files from one phone to another; Shut Up, an app from Nokia, silences the phone when the user turns it upside down; nAlertme, an antitheft app, sounds an alarm if the phone isn't shaken in a specific, preset way:
This article describes a basic definition of gesture based computing and provides its readers with technology and applications that are equipped with this feature.
