AARemu (https://github.com/donaldmunro/AARemu) 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 rotational sensors. The ARCamera

class which provides an impostor or mock 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 and precise seeks to bearing

locations are possible instead of to a video keyframe.

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.

This is the AARemu sample application which is a simple sample providing playback of 360 degree recordings made with ARemRecorder (also available on Play). To start playback drag the interface drawer on the left edge of the app out and click the Open button. The Open dialog allows selection of a recording made with ARemRecorder. To select a recording scroll down the ListView or type in the first few characters of the name of the recording in the TextView at the top of the dialog then click OK (the recordings are assumed to reside on Documents/ARRecorder). Hold the device at a constant vertical angle and rotate the device to playback the recording using the rotational sensors to find the frame matching the current bearing. The Review button allows reviewing the recording by ignoring the sensors and instead cycling the display between specified angles without having to rotate the device.
