Skin Tone Scanning and Cosmetics in 3D Skin Tone Color Space

A system comprising:

• a plurality of cosmetic products, each cosmetic product being associated with at least a skin tone identifier in a three-dimensional skin tone color space;
• a handheld scanning device that comprises a mobile communication device and a sensor assembly, wherein the handheld scanning device comprises a mobile communication device and a sensor assembly, the sensor assembly comprises a client side, a device side opposite to the client side, and one or more lenses on the client side, the mobile communication device comprises a scanner display on a front side and a scanning sensor on a back side, opposite to the front side, and the device side of the sensor assembly is attached to the back side of the mobile communication device so that while client side of the sensor assembly is directed toward a customer's skin of a customer, the scanning sensor and the one or more lenses are operatively coupled to perform scans of the customer's skin while the scanner display remains visible on the front side;
• a battery, enclosed within the handheld scanning device, that powers the handheld scanning device;
• the handheld scanning device is configured to determine a final skin tone result, determining the final skin tone result comprising:
• to determine the final skin tone result, while the client side of the sensor assembly is directed toward the a customer's skin at a first location, performing a first scan to generate a first intermediate result reflective of the first location, wherein the final skin tone result for the customer is unavailable for display on the scanner display after the first scan and before a second scan has been performed,
• while the client side of the sensor assembly is directed toward the customer's skin at a second location, performing the second scan to generate a second intermediate result reflective of the second location,
• using the first and second intermediate results, calculating the final skin tone result that is reflective of the first and second locations, and
• displaying the final skin tone result on the scanner display, wherein the final skin tone result references the three-dimensional skin tone color space, and each skin tone in the skin tone color space comprises three values or parameters to indicate its position in the skin tone color space;
• and
• the handheld scanning device is configured to determine a final skin condition result, determining the final skin condition comprising:
• to determine the final skin condition result, while the client side of the sensor assembly is directed toward the customer's skin at a third location, performing a third scan to generate a third intermediate result reflective of the third location, wherein the final skin condition result for the customer is unavailable for display on the scanner display after the third scan and before a fourth scan has been performed,
• while the client side of the sensor assembly is directed toward the customer's skin at a fourth location, performing the fourth scan to generate a fourth intermediate result reflective of the fourth location,
• using the third and fourth intermediate results, calculating the final skin condition result that is reflective of the third and fourth locations, and
• displaying the final skin condition result on the scanner display.
