Publication number: 20240103632Abstract: Aspects of the subject technology relate to providing gesture-based control of electronic devices. Providing gesture-based control may include determining, with a machine learning system that includes multiple machine learning models, a prediction of one or more gestures and their corresponding probabilities of being performed. A likelihood of the user's intent to actually perform that gesture may then be generated, based on the prediction and a gesture detection factor. The likelihood may be dynamically updated over time, and a visual, auditory, and/or haptic indicator of the likelihood may be provided as user feedback. The visual, auditory, and/or haptic indicator may be helpful to guide the user to the correct gesture if the gesture is intended, or to stop performing an action similar to the gesture if the gesture is not intended.Type: ApplicationFiled: September 18, 2023Publication date: March 28, 2024Inventors: Matthias R. HOHMANN, Anna SEDLACKOVA, Bradley W. GRIFFIN, Christopher M. SANDINO, Darius A. SATONGAR, Erdrin AZEMI, Kaan E. DOGRUSOZ, Paul G. PUSKARICH, Gergo PALKOVICS
