A method for aligning a removably attachable skin analysis device to a mobile device is disclosed. The method is particularly applicable to skin analysis devices comprising a housing that defines a housing aperture, the housing aperture comprising a housing aperture center and wherein the housing aperture is centered on a camera of the mobile device when the skin analysis device is in an aligned position, and the method includes capturing, with the camera, a current position image, wherein the current position image comprises at least a portion of the housing aperture, processing the current position image to determine if the current position is the aligned position and communicating a message from the processing.

Systems and methods for assessing PPG signals generated based on transdermal optical data can include a computing device generating a color intensity signal using an acquired sequence of transdermal images of a subject. The computing device can compute a signal quality metric of the color intensity signal. The computing device can provide an indication of a quality of the color intensity signal for display on a display device associated with the computing device. The indication of the quality of the color intensity signal can be determined based on the signal quality metric.

A triage system that determines whether a user is likely to have contracted a disease based on sensor data received from a user device (e.g., a smartphone or activity tracker). Each symptom is identified by comparing sensor data to a predetermined baseline and comparing the difference to a predetermined symptom threshold. Because direct measurement of symptoms using the sensors available to the user may not be feasible or sufficiently accurate, the triage system also uses surrogates the identify certain symptoms. For example, a fever may be identified using heart data, a cough or shortness of breath may be identified by analyzing recorded sound, fatigue may be identified by analyzing the movement of the user device, and loss of smell or taste may be identified by recording sound and using speech detection algorithms to identify phrases in the recorded sound indicative of loss of smell or taste.
