Headlamps are a staple in virtually every nighttime outdoor activity. Modern headlamps are relatively simple devices: most consist of a button that controls a bright LED, and nothing more. More expensive headlamps are brighter, lighter, and may have a more complex user interface. Regardless of the interface, headlamps require the user to always be thinking about adjusting them when in variable conditions.

What if there was a headlamp that you didn't have to think about? Presented below is a concept for a "smart" headlamp that does all of the thinking for you:

The proposed sensors include:

- 8x8 infrared matrix sensor (detects analog heat signature of other people, fire, etc.)

- 8x8 time-of-flight matrix sensor (detects distance of objects closer than 4m)

- Several RGB light sensors to detect ambient light and other headlamps/lights

- 3-axis accelerometer, gyroscope, and magnetometer; barometer and temp sensor 

Because of the ubiquity of headlamps in so many activities, there isn't one preset that will work for every activity. You might want your headlamp to turn down when looking at another headlamp, but not the light of an oncoming car. To solve this problem, the headlamp can be equipped with Bluetooth and paired with a phone or sports watch to select the mode and change sensitivity.
