Peter Cohen of The Loop explains what the iPhone 4 gyroscope is all about and why you should care.
iPhone 4 adds a gyroscope – a device that measures orientation, rather than just velocity. Gyroscopes are commonly used in aircraft to measure pitch, roll and yaw, and the iPhone’s gyro is no different in this regard…
When the output of the iPhone’s gyroscope is paired with the output from the accelerometer, iPhone developers will now be able to create applications that can sense motion on six axes – up/down, left/right, forward/backward, combined with rotation around three perpendicular axes – pitch, yaw, and roll.
This will put iPhone 4 well ahead of the capabilities of other smartphones when it comes to playing games, as well as the Nintendo DS and the Sony PSP (Nintendo’s forthcoming 3D handheld system purportedly has similar features, though Nintendo has not, as of yet, formally introduced the device).
Gaming on the iPhone is about to be taken to a whole another level.
