This one’s got us raising an eyebrow: an app that figures out not only the distance to an object, but its speed — for a buck.
From the app’s press release:
Employing the device’s three-axis gyro and basic trigonometry establishes distance. Speed and laps are measured using the motion sensing of the video camera, timing the interval between the object entering and leaving the frame. The app is compatible with iPhone 3Gs, iPhone 4, and iPod touch 4.
We’re assuming that though SpeedClock is compatible with the 3Gs, it must deliver somewhat less-accurate results on it as there’s no gyro. We’re also assuming the app isn’t all that accurate for a number of reasons, not the least of which is that the app requires the user to guesstimate the distance from the iPhone to the object. But who knows, maybe one day the tech’ll get there; somehow the idea of state troopers aiming iPhones instead of radar guns seems somewhat more cuddly.
