This iPhone pulse monitor was created to measure how people react to good design on a deeper level. Using the mobile phone's camera and flashlight, the Morpholio Project tracks the user's heart rate with a 3D printed clip-on device. While it is intended to gain insight into people's subconscious emotions, it could have other uses outside the design world. The field of health care is an obvious one.
The Morpholio Project's new platform uses a biofeedback medical technique called photoplethysmography (or PPG) to assess how design affects a person. PPG is what makes the iPhone pulse monitor work, by taking pictures of an illuminated part of the skin and analyzing the changes of color resulting from blood rushing through it. The 3D printed attachment is optimized to get the best picture placement.
