HISTORYIn the early 1960s, users could move a light-emitting pen tocontrol the Sketchpad computer-aided design system. Severalsubsequent commercial systems also worked with light-emittingpens. Research into camera-based computer vision for gesturerecognition began in earnest in the early 1990s at places suchas the Massachusetts Institute of Technology Media Lab,Japan’s Advanced Telecommunications Re- search InstituteInternational, and the University of Zurich. Since then, a fewcompanies have sold gesture-recognition software. Until now,though, the technology hasn’t had a significant commercialimpact.
INTRODUCTIONGesture Recognition is a topic incomputer science and languagetechnology with the goal of interpretinghuman gestures via mathematicalalgorithms. Gestures can originate fromany bodily motion or state but commonlyoriginate from the face or hand. Currentfocuses in the field include emotionrecognition from the face and handgesture recognition. Many approacheshave been made using cameras andcomputer vision algorithms to interpretsign language.
USES OF GESTURERECOGNITIONTECHNOLOGY Sign language recognition Directional indication through pointing Control through facial gestures Alternative computer interfaces Immersive game technology Virtual controllers Affective computing
INPUT DEVICES Depth-aware cameras. Stereo cameras. Controller-based gestures. Single camera
CORE COMPETENCY Hand Tracking and MouseReplacement Dynamically tracks users hand,converting to mouse movement. Allows for multi-touchinteractivity. Full-Body Tracking andImmersion Puts the user in the screen. Analyzes and reacts to users fullrange of motion. Provides breakthrough healthsolutions.
