DETECTING YOUR HEARTBEAT

The science behind Choice Compass is based on heartbeat patterns. These patterns reflect how the human body responds to conscious and subconscious feelings, including those related to decision making.

In order to measure your heartbeat patterns, Choice Compass uses either your smartphone’s camera itself or a compatible Bluetooth heart rate monitor (Polar, Elite HRV) to detect changes in the amount of blood flowing through your finger over time — these changes are related to your heartbeat patterns.

Choice Compass has algorithms that detect each heartbeat based on the variations in blood flow color. It then uses this to determine not only the average beats per minute (BPM), but the interval between beats, or the interbeat interval (IBI). It is the IBI that is of most interest to us as its patterns contain information about our body’s inner state.
