Motion detection is one of the key technologies that many portable devices are taking advantage of today. Motion sensing in the smartphone market is used to change the orientation of the screen depending on how the device is held and for controlling video games.
The iPhone was one of the first devices to take advantage of an accelerometer to control some phone functions. InvenSense has announced what it calls the world's first motion processing unit dubbed the MPU-3000. The device features an integrated digital 3-axis gyro and a digital motion processor hardware acceleration engine.
The new chip is aimed at the smartphone market and provides features for motion processing from 250 to over 2000 degrees per second. The device also supports gesture user interface control. The MPU-3000 is small at 4x4x0.9mm and uses I2C or SPI interfaced. The little chip is priced under $4 each, presumably in bulk.
