iPhone Developer Craig Hunter on Palm’s WebOS SDK

Craig Hunter:

While the webOS SDK allows access to raw accelerometer data, it’s limited to a 4 Hz sampling rate (that’s four samples per second). Applications like gMeter and greenMeter need 50-100 Hz to even be practical, and most games need at least 20 Hz for smooth inputs that won’t lag too far behind typical graphics framerates. A low rate of 4Hz is not usable for dynamic motion where high fidelity is desired. Accelerometer support in the webOS is suitable for detecting basic movement of the phone for interface rotation, but that’s about it.
