Augmented Reality Sound Mixer Demo – taterboy
October 8th, 2009 | Filed under: ActionScript 3, Audio, Flash, Flex

Here is one of the demos we built recently to show some possible uses of Augmented Reality and Flex. This demo uses the FlarToolKit to detect the instrument patterns and place a 3D plane on screen with Papervision 3D. For the main mixer we use mp3s and 2D animations to show the different audio tracks. 3D is the future, but for now the low polygon count does not stand up to fully illustrated 2D graphics yet. We are using the FlarToolKit more as an input device to turn on and off audio tracks and to change the volume.

The Possibilities:
This sample is just a seed for the possibilities of future technology in live performances, not tied to a computer, how different patterns could create cues for video, audio, lighting and effects. The sample also shows how layering different symbols in different order can change the dynamic of the user experience.

To use this demo you will have to print and cut out the markers from this PDF file.

Included Symbols:
Drum Track
Bass Track
Horn Track
Guitar Track
Volume Fader
Eject (not used)

Note: Make sure you have plenty of black ink, use mat paper or card stock for best results. Depending on the lighting and what is behind you may have to put a piece of white paper behind the marker to force the webcams contrast higher.

To start Jamming, show a track marker to your webcam to display or remove an audio track. You can use the Volume marker to lower the sound to 20% or raise it back to 100%. The first time a marker is shown to the camera, it adds a track or lowers the volume. If you show a marker to the camera again, the previous action from that marker will reverse.

Note: In our demo we start with the drum and bass tracks to build a good rhythm, then add the horn. It sounds OK. Then remove the horn and add the guitar lead. The horn and guitar are both lead tracks and were not really meant to play at the same time, but this is about expression so there are no rules.

Enjoy.
