![]() ![]() The accelerometer selected for the application is Freescale’s MMA7260Q, a low-g three-axis device with a g-select option that can be used to chose a range of ☑.5, ☒ ±4 or ☖g. “It is measuring gravity, so it can use both the X and the Z for that type of rotation and when it is tilting forward, it can use the Y and the Z for getting accurate tilt measurements,” says Michelle Kelsey, marketing manager for Inertial Sensors, Freescale Semiconductor. However, the accelerometer has a non-linear tilt output, so using the third axis for the X and Z or the Y and Z measurements provides more accurate tilt data. For this application, tilt recognition could have been done with a two-axis accelerometer. With the user balancing on the board, the accelerometer provides tilt feedback data regarding the motion and translates the measurements into a character in the game on either a skateboard or snowboard that tilts in the same direction. ![]() The accelerometer’s location in an actual board allows players to really get into the game. Qmotions-Xboard full-motion game controller uses a three-axis accelerometer developed by Freescale that measures body movement and converts it into full body action. At the 2007 Consumer Electronics Show (CES), Qmotions and Freescale Semiconductor showed attendees how to become an integral part of a snow- or skateboarding game. ![]() One of the more visible applications in 2006 was Nintendo’s Wii. The cost is low enough that new interactive games have been developed using accelerometers for motion detection. Now that low-cost accelerometers exist, they are being applied for motion detection and stabilization in a variety of consumer electronics products from cameras to hard disk drives. Carmakers and their suppliers created the low-cost semiconductor accelerometer business based on the requirement for these sensors in airbag systems. However, once new sensors exist, sometimes it is all fun and games, especially for users of some of the newest toys that take advantage of built-in sensing capabilities. The initial applications that drive sensor companies to invest in the research to bring new technologies to market are frequently in automotive, medical, industrial or military/aerospace.
