SAN JOSE, Calif. – Apple apparently tested a three-axis gyroscope from InvenSense in its iPad, but probably plans to use a similar device from STMicroelectronics in a future version of the tablet, according to an analysis by UBM TechInsights.
The Apple iPhone 4 was the company's first smartphone to uses a three-axis gyroscope, specifically the L3G4200D from STMicroelectronics. The chip is geared to provide more detailed position information than an accelerometer or GPS.
