Claim 14:
15. A personal care device comprising one or more sensors, at least one processor, and memory, the memory having stored therein computer-executable instructions configured to cause the personal care device to perform steps comprising:
obtaining, via the one or more sensors, sensor data with respect to a human body surface on which a digital 3-dimensional model is based, wherein portions of the human body surface correspond to reference points in the digital 3-dimensional model;
based at least in part on the sensor data obtained via the one or more sensors, calculating a relative location of the personal care device relative to the reference points in the digital 3-dimensional model; and
determining a true position of the personal care device with respect to the human body surface based at least in part on image data of the personal care device in use, pre-determined physical dimensions of the personal care device, and the relative location of the personal care device, wherein the image data of the personal care device is captured by one or more cameras of a computing device separate from the personal care device; and
based on the true position of the personal care device, performing application of a cosmetic product, or detection of a skin feature, or administration of a therapy.
