    摘要: A method and system for monitoring the location of an oral care device (102) within the mouth of a user, includes: an oral care device (102) having a light source (104); an optical sensor (112) configured to receive light emitted by the light source and to receive light reflected from a user using the oral care device; a computing device (110) adapted to receive and process signals generated by the optical sensor, and programmed to: detect at least one facial feature of the user from the received light reflected from a user; estimate the location of the user's teeth according to the detected facial feature; determine a location of the light source according to the received emitted light; compare the location of the light source to the location of the teeth to estimate the position of the oral care device with respect to the teeth of the user.

    摘要: The invention relates to a device (1) and a method for determining a relational position of a mobile device (14, 14′). An embodiment provides for equipping the mobile device (14, 14′) with a light source (15) to project a light image on the subject (18) during use, while a camera equipped device (12) is observing the subject (18). The camera (13) is used to identify both landmarks (19) on the subject's face and the light image (17) allowing the position of the device (14, 14′) relative to the user (18) to be calculated. This system may use the computing power in the camera equipped device (12) for image analysis, and no advanced processing needs to be performed by the mobile device (14, 14′). Further, no communication between the mobile device (14, 14′) and the camera equipped device (12) is required to establish the relative position of the personal care device.
