MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202621025363 A) filed by Maulana Azad National Institute Of Technology Bhopal on March 03, 2026, for Method And System For Hands-Free Cursor Control Using Head Rotation And Blink Detection.
Inventors include Chouhan, Chaitanyaadityasingh; Yadav, Kuldeep Singh; Das, Sujoy; and Srivastava, Namita.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: A hands-free cursor control system (100) and method (500). The system (100) includes a video acquisition module (116) configured to acquire image frames of a user's face, a facial-landmark detection module (118) configured to detect facial landmarks from each frame, a head-rotation module (120) configured to determine head-rotation indicators based on positional relationships among the facial landmarks, a neutral-zone evaluation module (122) configured to compare head-rotation indicators with neutral-zone thresholds and determine rotational movement for cursor actuation, a motion-smoothing module (124) configured to apply temporal filtering to generate smoothed motion inputs, a cursor-movement module (126) configured to convert smoothed motion inputs into cursor- movement commands, a blink-detection module (128) configured to detect blink events by evaluating an eye-aspect ratio, a blink- action module (130) configured to generate command inputs in response to blink events, and an operating abstraction interface (110) configured to provide commands to a host operating system.
