STMicroelectronics and Ball-IT Oy, a provider of advanced real-time wireless sensor solutions, have announced a novel MEMS-based wireless motion-control device. This golf ball-sized object can operate as a free-hand personal computer mouse, compass, measuring tape, pedometer and a 3D-object controller.

Enabled by ST's Micro-Electro-Mechanical Systems (MEMS) technology, which uses standard semiconductor technology to mass produce precise micron-sized structures that interact with the physical world, Ball-IT's wireless ball controller responds to changes in position, direction, speed and acceleration, down to the most delicate movements and translate those movements into immediate on-screen action. The ball is also sensitive to pressure, so its motion-sensitive user interface includes squeeze-prompted commands.

The small dimensions and ultra-low power consumption of ST's three-axis digital acceleration sensor contribute to the user-friendly size and weight of the smart ball and prolong its battery life.

"ST's strengths in MEMS and leadership in micro-machining technologies result in the market's best combination of sensor resolution, size, power and cost characteristics," said Johannes Väänänen, Chairman of Ball-IT. "ST's accelerometers fit perfectly with our real-time wireless sensor technology to create a compelling case for the adoption of motion-based user interfaces in a wide range of personal electronic devices."
