Hi, first post here. Yesterday i downloaded the PSSuite SDK, all seems fine, it seems to be a very nice API, well organized.
I'm currently developing an augmented reality game for Windows Phone 7 and, because of similarities of XNA and PSSuite, i wanted to port the game to this platform. But as far as i know, there doesn't seem to be available a Compass API and no way to get the rear camera feed of the Vita! Do you plan to add these features?

Have you looked through the Motion namespace and samples? I've not used them myself but I would've thought they had compas support in there... Not sure about Camera though. The SDK is still a littel raw so the team are always looking at adding new features.
AR is one area Sony are really pushing the Vita so I would've expected camera support.

I briefly looked at the Motion sample myself and tested it on Vita, and that gives absolute values for the x,y, and x device orientation, so that should cover the compass part, but unfortunately the camera's I think are still on the to-do list for the SDK.

The SDK has the Motion class that gives us a MotionData with only two properties:
- The accelerometer reading in the Acceleration property.
- The gyroscope reading in the AngularVelocity property.
These two, as far as i know, can't completely replace the compass. For an augmented reality game/app, we need to access the Camera, the Accelerometer and the Compass. The Gyroscope allows for a finer smooth step in the Compass reading, because the later can flutuate widly in strong magnetic environments.
I've checked the MotionSample and it only gives the output of the Acceleration and AngularVelocity, with no pratical example.
Does anyone have further info about this?

Thank you for your questions
> These two, as far as i know, can't completely replace the compass
Unfortunatley at this moment in time, there are no APIs to get the current oreientation (N/E/S/W) of the device.
> We need to access the Camera
We are aware that there are many possible AR games that people would like to make, which would require the gyros, compass and camera. We have no updates at this moment in time about the Camera feature request, but it has been acknowledged.
> Does anyone have further info about this?
How would you like to use the data? The accceleration will measure the rate of change of speed that the device is experiencing, and the agular velocity will report the rate of change of its angular displacement (rotation on the x,y,z axis).

Thanks for your answer. Sorry about the delay in this response.
My particular AR application is a 3D game that "lays on top" of the real camera feed. The player can point the Vita/phone anywhere like it was a binocular into the virtual world. The scenario is the real world around him, but filled with 3D objects. Sorry, but i can't reveal more thant this.
I currently have this tech working very nicely on the Windows Phone 7, because it's SDK gives me the Compass, Accelerometer and the Camera feed. My test phone (samsung omnia 7) doesn't have a gyroscope, but by carefully smoothing the compass input data, i can make the virtual motion fluid enough.
Look, i understand this maybe an odd scenario that very few developers will use (it's a bit tricky), but it is possible and playable on the Windows Phone, so why not on the Vita?
