Optical measurement device and a method for an optical measurement

A method for a reflectance-based optical measurement, the method comprising:

• removably coupling a smaller than palm size reflectance-based optical measurement (RBOM) accessory to a personal mobile processing device in a cableless configuration;
• outputting light to a surface portion of a user for measurement;
• detecting the output light reflected from said surface portion of the user as a signal;
• transmitting the detected signal to the personal mobile processing device for deriving from the detected signal, saturation of peripheral oxygen (SPO2) information of the user;
• and
• correlating a quality of the detected signal with an amount of pressure applied on the RBOM accessory by:
• computing an area under waveforms of detected signals corresponding to a variety of applied pressure amounts, and determining an optimum pressure to correspond a largest computed area, from the variety of applied pressure amounts.
