Abstract
A handheld personal care device having one or more light emitting elements and one or more light receiving elements is disclosed. Each of the light receiving elements is configured to receive light and output a respective measurement signal representing measurements of the received light. The handheld personal care device also has a control unit to estimate a position and/or an orientation of the device relative to a subject. The light emitting elements and the light receiving elements are arranged on the device such that, depending on the position and/or the orientation of the device relative to the subject, at least one of the light receiving elements can receive light emitted by at least one of light emitting elements and reflected by a reflective surface in the environment of the subject. The control unit estimates the position and/or the orientation of the device relative to the subject based on an analysis of the respective measurement signals of the light receiving elements.
