Health tracking device

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of a wearable user device, cause the one or more processors to:
• identify a set of images captured from different orientations or positions;
• receive sensor data from a spectrometer sensor of the wearable user device;
• utilize the set of images to determine a volume of a portion of a user;
• and
• provide, via a user interface, information based on the volume of the portion of the user and the sensor data.

A method comprising:

• identifying, by a device, an image of a user;
• identifying, by the device, sensor data obtained by a spectrometer sensor of the device;
• performing, by the device, a pattern recognition analysis on the image of the user;
• determining, by the device, that the user is in a comfort state based on performing the pattern recognition analysis on the image of the user;
• correlating, by the device, the comfort state with the sensor data to determine a recommendation for the user;
• and
• providing, by the device, information regarding the recommendation.
