Claim 7:
8. A non-transitory computer-readable medium having stored thereon computer-executable instructions configured to cause a computer system comprising one or more computing devices to perform steps comprising:
obtaining a digital 3-dimensional model of a human body surface, wherein portions of the human body surface correspond to reference points in the digital 3-dimensional model;
obtaining image data of a personal care device and image data of the human body surface on which the digital 3-dimensional model is based, wherein the image data of the personal care device and the image data of the human body surface is captured by one or more cameras of a computing device separate from the personal care device;
based at least in part on the image data of the human body surface, calculating a relative location of the personal care device relative to the reference points;
determining a true position of the personal care device with respect to the human body surface based at least in part on the image data of the personal care device, pre-determined physical dimensions of the personal care device, and the relative location of the personal care device; and
based on the true position of the personal care device, cause an interaction of the personal care device with the human body surface, wherein the interaction includes application of a cosmetic product or administration of a skin therapy.
