Title
(EN) ROBUST RADAR-BASED GESTURE-RECOGNITION BY USER EQUIPMENT
(FR) RECONNAISSANCE GESTUELLE À BASE D'UN RADAR ROBUSTE PAR UN ÉQUIPEMENT UTILISATEUR
Abstract
(EN)
Systems and techniques are described for robust radar-based gesture-recognition. A radar system (104) detects radar-based gestures on behalf of application subscribers. A state machine (2000) transitions between multiple states based on inertial sensor data. A no-gating state (2002) enables the radar system (104) to output radar-based gestures to application subscribers. The state machine (2000) also includes a soft-gating state (2004) that prevents the radar system (104) from outputting the radar-based gestures to the application subscribers. A hard-gating state (2006) prevents the radar system (104) from detecting radar-based gestures altogether. The techniques and systems enable the radar system (104) to determine when not to perform gesture-recognition, enabling user equipment (102) to automatically reconfigure the radar system (104) to meet user demand. By so doing, the techniques conserve power, improve accuracy, or reduce latency relative to many common techniques and systems for radar-based gesture-recognition.

La présente invention concerne des systèmes et des techniques pour une reconnaissance gestuelle à base d'un radar robuste. Un système radar (104) détecte des gestes à base d'un radar pour le compte d'abonnés d'une application. Une machine à états finis (2000) passe d'un état à l'autre parmi de multiples états sur la base de données de capteur inertiel. Un état de non déclenchement (2002) permet au système radar (104) de délivrer des gestes à base d'un radar aux abonnés de l'application. La machine à états finis (2000) comprend également un état de déclenchement logiciel (2004) qui empêche le système radar (104) de délivrer les gestes à base d'un radar aux abonnés de l'application. Un état de déclenchement matériel (2006) empêche le système radar (104) de détecter l'ensemble des gestes à base d'un radar. Les techniques et les systèmes permettent au système radar (104) de déterminer quand il n'est pas nécessaire d'effectuer une reconnaissance gestuelle, permettant à un équipement utilisateur (102) de reconfigurer automatiquement le système radar (104) pour répondre à la demande de l'utilisateur. Ainsi, les techniques conservent la puissance, améliorent la précision ou réduisent la latence par rapport à de nombreuses techniques et de nombreux systèmes communs pour la reconnaissance gestuelle à base d'un radar.
