A feedback loop is a system where outputs are fed back into the system as inputs, increasing or decreasing effects. Often feedback and self-correction lead to adjustments varying with differences between actual output and desired output.

• Smart Watches Encouraging “More Steps” To Get Lazy People To Walk

Another example of a feedback loop is the regulation of your body temperature. The body’s temperature is monitored by the brain, and if the temperature falls outside of the normal range, the brain signals the body to take action to warm up or cool down. The body then takes action to raise or lower its temperature, and the feedback loop continues until the body’s temperature is back within the normal range.
