Background & analysis
According to a Phys.org report on November 12, 2026, researchers have for the first time tracked the movement of a person's entire body using ultrasonic sound waves, relying on just an off-the-shelf smartwatch and a lightweight AI model. The report stresses that the approach removes any dependence on cameras, preserving privacy while still delivering whole-body motion tracking. The available material does not identify the research institution behind the work, the specific smartwatch model used, the name of the AI model, or its tracking accuracy, and no further developments have been published. The story therefore remains at this initial announcement stage.

How is heat calculated?About the methodHide
Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
