ARem is a software tool enabling simulation of Augmented Reality
    by allowing an AR developer to record a 360 degree view of a
    location using the devices camera and orientation sensors (this
    functionality is provided by the ARemRecorder app). The ARCamera
    class which provides an impostor of the Android camera class
    can then be used to preview the recorded scene instead of the live
    camera preview provided by the Android Camera class. The ARCamera
    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
    based on the current bearing returned by the orientation
    sensor(s). 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, RGB or RGB565 format
    and not as video so the preview can be accessed in both
    clockwise and anti-clockwise directions.

The tool is aimed at developers of outdoor mobile AR application
    as it allows the developer to record one or more 360 degree
    panoramas 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.
