There are actually two transformations applied: 1) device rotation (rotate whatever portrait / landscape the user selects to one "standard internal" orientation) and 2) yaw/tilt/roll transformation - which is either a preset, or individual, or individual locked. So the presets do not work on different device orientations but after 1) has been applied. This makes the whole process a lot easier to understand when coding this stuff.gplracerx wrote:I like the new accelerometer calibration. The internal camera setting worked like a charm. You might have a little too much yaw in the LHT and RHT presets, though. It looked like about 45 degrees. Using a forced calibration on the individual setting solved that problem, but a straight ahead portrait preset like the internal camera straight ahead landscape preset would be nice.
For the actual angles used for tilt and yaw, please check illustration #4 in LapTimer's new Quick Reference. It animates through RHT, LHT, video and motorbike presets. Like any "one size fits all" approach, the presets are finally always wrong. But they will be better than an individual calibration being off by accident... For advanced users with a fixed mount, a locked individual calibration is the best approach.
