Aaremu

AARemu is a software tool enabling simulation of Augmented Reality by allowing an AR developer to record either an interactive 360 degree or a non-interactive free-form view of a location using the devices camera and orientation sensors (this functionality is provided by the ARemRecorder app). The ARCamera/ARCameraDevice classes which provides a mock implementation of the Android Camera API classes can then be used to preview the recorded scene instead of the live camera preview provided by the Android Camera class. The preview callback is analogous to the standard Camera preview callback except that the preview bytes provided in the callback are extracted from a file created by the recorder application. These preview bytes are passed to the development code via the same preview callback as provided by the standard Camera classes and can thus be processed by Computer Vision algorithms before being displayed by the client application. The frames are stored as individual video frames in RGBA format and not as video so the preview can be accessed in any direction. The tool is aimed at developers of mobile AR applications as it allows the developer to record view(s) of a given location and then debug and test the AR application in the comfort of a office or home without having to make extensive changes to the programming code.
