The patent details a method by which Kinect will measure a user's body proportions to determine their age.
"The age group of a person in a field of view of the camera can be determined based on metrics of a 3D body model," the patent states. "The metrics are particularly indicative of age group.
"Based on the age group, a profile of the user is automatically updated with various parental control settings which control access to the electronic media device."
The software can block specified content from users under a certain age as well as alter the displayed image on-screen if a minor is seen in the Kinect's field of view. The patent describes parental controls applying to both games and live TV, a feature that will be added in the next Xbox 360 dashboard update.
Like the existing parental settings, the Kinect parental controls could also be disabled entirely in the system's menu.
Microsoft has not commented on when or if the Kinect parental controls will be implemented. The patent was filed on March 29 this year and made public on September 29.
