Gesture Recognition
Gesture recognition is a topic in computer science and language technology with the goal of interpreting human gestures via mathematical algorithms. It is a subdiscipline of computer vision. Gestures can originate from any bodily motion or state but commonly originate from the face or hand. Current focuses in the field include emotion recognition from face and hand gesture recognition. Users can use simple gestures to control or interact with devices without physically touching them. Many approaches have been made using cameras and computer vision algorithms to interpret sign language. However, the identification and recognition of posture, gait, proxemics, and human behaviors is also the subject of gesture recognition techniques. Gesture recognition can be seen as a way for computers to begin to computer processing of body language, understand human body language, thus building a richer bridge between machines and humans than primitive text user interfaces or even GUIs (graphic ...

Pose (computer Vision)
In computer vision and robotics, a typical task is to Object detection, identify specific objects in an image and to determine each object's position and orientation (geometry), orientation relative to some coordinate system. This information can then be used, for example, to allow a robot to manipulate an object or to avoid moving into the object. The combination of ''position'' and ''orientation'' is referred to as the pose of an object, even though this concept is sometimes used only to describe the orientation. ''Exterior orientation'' and ''translation'' are also used as synonyms of pose. The image data from which the pose of an object is determined can be either a single image, a computer stereo vision, stereo image pair, or an image sequence where, typically, the camera is moving with a known velocity. The objects which are considered can be rather general, including a living being or body parts, e.g., a head or hands. The methods which are used for determining the pose o ...

Time-of-flight Camera
A time-of-flight camera (ToF camera) is a range imaging Range imaging is the name for a collection of techniques that are used to produce a 2D image showing the distance to points in a scene from a specific point, normally associated with some type of sensor device.

Structured Light
A structured light pattern designed for surface inspection An Automatix Seamtracker arc welding robot equipped with a camera and structured laser light source, enabling the robot to follow a welding seam automatically Structured light is the process of projecting a known pattern (often grids or horizontal bars) on to a scene. The way that these deform when striking surfaces allows vision systems to calculate the depth and surface information of the objects in the scene, as used in structured light 3D scanners. ''Invisible'' (or ''imperceptible'') structured light uses structured light without interfering with other computer vision tasks for which the projected pattern will be confusing. Example methods include the use of infrared light or of extremely high frame rates alternating between two exact opposite patterns. Structured light is used by a number of police forces for the purpose of photographing fingerprints in a 3D scene. Where previously they would use tape to extract ...

Wired Glove
A wired glove (also called a dataglove [Oxford English Dictionary] or cyberglove) is an input device for human–computer interaction worn like a glove. Various sensor technologies are used to capture physical data such as bending of fingers. Often a motion tracker, such as a magnetic tracking device or inertial tracking device, is attached to capture the global position/rotation data of the glove. These movements are then interpreted by the software that accompanies the glove, so any one movement can mean any number of things. Gestures can then be categorized into useful information, such as to recognize sign language or other symbolic functions. Expensive high-end wired gloves can also provide Haptic technology, haptic feedback, which is a simulation of the sense of touch. This allows a wired glove to also be used as an output device. Traditionally, wired gloves have only been available at a huge cost, with the finger bend sensors and the tracking device having to be bought se ...

Tangible User Interface
A tangible user interface (TUI) is a user interface in which a person interacts with digital information through the physical built environment, environment. The initial name was Graspable User Interface, which is no longer used. The purpose of TUI development is to empower collaboration, learning, and design by giving physical forms to digital information, thus taking advantage of the human ability to grasp and manipulate physical objects and materials. One of the pioneers in tangible user interfaces is Hiroshi Ishii (computer scientist), Hiroshi Ishii, a professor at the Massachusetts Institute of Technology, MIT who heads the Tangible Media Group at the MIT_Media_Lab, MIT Media Lab. His particular vision for tangible UIs, called ''Tangible Bits'', is to give physical form to digital information, making bits directly manipulable and perceptible. Tangible bits pursues the seamless coupling between physical objects and virtual data. Characteristics # Physical representation ...
