Modern interactive games continually strive for improved immersion in order to engage with the user better. Traditionally the way this immersion is achieved is through the use of improved visuals, novel controller interfaces or more recently through the use of wearable sensors. However, these approaches typically require additional hardware to function and may result in hygiene issues. This study presents a method that requires no physical contact and uses a camera to estimate heart rate for improved interactivity with the user. By capturing a live video feed containing the subject and analysing the colour space changes found in their forehead region, an estimated heart rate can be derived. The estimated heart rate can then be used to regulate the gaming environment or serve as an additional controller interface, which provides a more immersive experience. The results show the method is feasible and may prove useful in other affective computing systems.
