FALT was a project designed to give visual ambient feedback to users playing PC Games.

Equipment – PC, Arduino, Ikea 'Dioder' (Multicolor LED light set)

A pre-defined section of screen was used as the indicator. Most often this area was the Health Bar, the HP values were tracked either by pixel color or position (depending on the game). That info was fed into an Arduino; attached to the Arduino were 2 sets of tri-color LEDs. The LEDs were positioned behind and around the monitor to give an ambient glow. When HP decreased the lights would transition from green to red indicating low health and a greater sense of danger and urgency. Player response and feedback was monitored and recorded, player reported feeling more immersed in the gaming experience and more accurately aware when they were in danger, leading to faster reaction times.
