Ultra-Low Power Wiimote for Your Wrist, Arm, Hand and Leg
The mystery is solved for Wiimote, the Wii controller, as STMicroelectronics has announced its three-axis acceleration sensors as the working principle behind the Wiimote’s motion sensing technology.
Driven by ST’s Micro Electro-Mechanical Systems (MEMS) technology, the Wii controller can respond to changes in direction, speed and acceleration, down to the most delicate movements. The controllers use embedded acceleration sensors to enable players’ wrist-, arm- and hand movements to interact with the games. Tilt measurements allow users to move characters, while the three-axis acceleration sensing easily transforms the controller into a virtual sword, gearshift or musical instrument.
Besides sucking up only tiny-weeny power, the Wiimote is also made to fence off temperature variations, vibration and shock.
The acceleration sensor’s miniature dimensions of 5×5x1.5mm3 significantly contribute to the user-friendly volume and weight of the TV-control-shaped hand-piece. The ultra-low power consumption of ST’s MEMS devices prolongs the battery life of the controller and the high thermal stability avoids unwanted motion sensing in varying temperature conditions. The robust design of the sensor also provides very high immunity to vibration and a shock resistance up to 10,000g.
If you are confused by the physics jargon, I can only give you 3 words, Just Use It!
