  • For nearly forty years, the keyboard and mouse have been the primary means to interact with computers.
  • Now, new devices are appearing on the market that take advantage of motions that are easy and intuitive to make, allowing us an unprecedented level of control over the devices around us. Cameras and sensors pick up the movements of our bodies without the need of remotes or handheld tracking tools.
  • It is already common to interact with a new class of devices entirely by using natural gestures.
  • ...10 more annotations...
  • The Microsoft Surface, the iPhone and iPod Touch
  • , the Nintendo Wii, and other gesture-based systems accept input in the form of taps, swipes, and other ways of touching, hand and arm motions, or body movement
  • These are the first in a growing array of alternative input devices that allow computers to recognize and interpret natural physical gestures as a means of control.
  • As the underlying technologies evolve, a variety of approaches to gesture-based input are being explored. The screens of the iPhone and the Surface, for instance, react to pressure, motion, and the number of fingers touching the devices
  • Gesture-based interfaces are changing the way we interact with computers, giving us a more intuitive way to control devices.
  • urrently, the most common applications of gesture-based computing are for computer games, file and media browsing, and simulation and training
  • Because it changes not only the physical and mechanical aspects of interacting with computers, but also our perception of what it means to work with a computer, gesture-based computing is a potentially transformative technology.
  • The distance between the user and the machine decreases and the sense of power and control increases when the machine responds to movements that feel natural.
  • The kinesthetic nature of gesture-based computing will very likely lead to new kinds of teaching or training simulations that look, feel, and operate almost exactly like their real-world counterparts.
  • Larger multi-touch displays support collaborative work, allowing multiple users to interact with content simultaneously

  • Over the years we've seen plenty of surface and gestural interface computing systems and prototypes, but nothing mass-market -- nothing consumable, if you will.
  • Microsoft aims to change all that with Surface, its first foray into surface / gestural interfaces; arriving in the form of a 30-inch table-like display, Microsoft envisions its eventual uses as pervasive as imaginable, like ordering beverages from your restaurant table and silently scanning your wine bottle's RFID tag to automagically present information on the vineyard and vintage.

  • A Gesture Based Interface for Human-Robot Interaction Stefan Waldherr, Roseli Romero, and Sebastian Thrun Service robotics is currently a pivotal research area in robotics, with enormous societal potential
  • Service robotics is currently a pivotal research area in robotics, with enormous societal potential
  • This paper describes a gesture interface for the control of a mobile robot equipped with a manipulator
  • ...2 more annotations...
  • The interface uses a camera to track a person and recognize gestures involving arm motion
  • Two alternative methods for gesture recognition are compared: a template based approach and a neural network approach. Both are combined with the Viterbi algorithm for the recognition of gestures defined through arm motion (in addition to static arm poses).

  • 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.
  • ...2 more annotations...
  • 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.

  • Gesture recognition is a topic in computer science and language technology with the goal of interpreting human gestures via mathematical algorithms. Gestures can originate from any bodily motion or state but commonly originate from the face or hand.

      Gesture based computing can also be referred to as gesture recognition. This sentence briefly describes the defintion of this feature.
  • Gesture recognition can be seen as a way for computers to begin to understand human body language, thus building a richer bridge between machines and humans than primitive text user interfaces or even GUIs (graphical user interfaces), which still limit the majority of input to keyboard and mouse.

      This sentence provides numerous ways in which gesture based computing can be beneficial to the environment.
  • Gesture recognition enables humans to interface with the machine (HMI) and interact naturally without any mechanical devices. Using the concept of gesture recognition, it is possible to point a finger at the computer screen so that the cursor will move accordingly. This could potentially make conventional input devices such as mouse, keyboards and even touch-screens redundant. Gesture recognition can be conducted with techniques from computer vision and image processing.
  • ...10 more annotations...
  • Gesture recognition is useful for processing information from humans which is not conveyed through speech or type. As well, there are various types of gestures which can be identified by computers.
