Samsung patents radar system that tracks hand gestures from multiple people
This patent describes a method using radar sensors to identify and track hand movements from several users at the same time. The system first locates the users, then switches between different radar settings to capture detailed gesture data for each person within specific zones.
In the filing’s own words
An embodiment includes a method of multi-user gesture recognition includes determining positions of a plurality of users based on a first radar information from at least one radar, determining a plurality of regions of interest for the plurality of users based on positions of the plurality of users, in a first duty cycle of a plurality of duty cycles, obtaining a second radar information using a first radar configuration that includes a first set of parameters for gesture recognition at a range of distances based on the plurality of regions of interest, in a second duty cycle, obtaining a third radar information using a second radar configuration, and detecting a first user gesture from a first user of the plurality of users and a second user gesture from a second user of the plurality of users based on the second and third radar information.
What exactly they claim (claim 1)
1. A method of multi-user gesture recognition, comprising: determining positions of a plurality of users based on a first radar information from at least one radar; determining a plurality of regions of interest for the plurality of users based on positions of the plurality of users; in a first duty cycle of a plurality of duty cycles, obtaining a second radar information using a first radar configuration that includes a first set of parameters for gesture recognition at a range of distances based on the plurality of regions of interest; in a second duty cycle of the plurality of duty cycles, obtaining a third radar information using a second radar configuration that includes a first radar mode for a first time period and a second radar mode for a second time period based on the plurality of regions of interest, wherein the first radar mode includes the first set of parameters for gesture recognition at the range of distances and the second radar mode includes a second set of parameters for gesture recognition within a closer range of distances; and detecting a first user gesture from a first user of the plurality of users and a second user gesture from a second user of the plurality of users based on the second radar information and the third radar information.
