This project centres around eradicating potentially dangerous medical design bias. SONO provides a service that allows any medical device to be calibrated to any skin tone and therefore work accurately and inclusively.

The service consists of two devices; the scanner and the pulse oximeter. The scanner uses individual typology angle to scan and categorise the skin tones into six different types. It then syncs to the secondary device of the pulse oximeter and this then changes its brightness accordingly by getting brighter the darker the skin tone. This family of products is the perfect balance of consumer and medical design and is one touchpoint within a larger system that can help eradicate skin tone based medical implicit bias.
