 The recent advances in MEMS and low-power wireless technologies have enabled the introduction of new context aware game controller. Different types of inertial based game controllers have recently be introduced, such as the Nintendo Wiimote and the PS3 Sixaxis. Similarly, the miniaturised e-AR sensor can be used as a human-computer interface for games. By positioning the sensor on the user’s ear, the orientation of the head as well as the body can be captured by the e-AR sensor for controlling the games. Compared to other devices, the e-AR sensor is much more intuitive to use and brings real physical involvement into the game itself.
e-AR is a low power, miniaturised ear-worn activity recognition sensor that has a unique bio-inspired design inspired by the semicircular canals of the inner ear. This means that the sensor is highly sensitive, easy-to-wear, and non-intrusive. The device allows the detection of a range of indices including gait cycle, steady/unsteady locomotion, acceleration, and spinal/joint shock wave transmission.
To demonstrate the unique features of the e-AR sensors, two open-source games, namely Tux racer and Never ball, have been augmented to use the e-AR sensor as the user interface. By wearing the e-AR sensor, a user can play the game by moving his/her head or body, and the penguin (in Tux racer) or the ball (in Never ball) will follow the movements accordingly.
