How to

  1. To use the AR app you’ll need a computer with access to the Internet (to download the app to your computer) and a webcam (built-in or external);
  2. The app doesn’t need constant access to the Internet so you can download and prepare it at any location and then use it offline;
  3. The app requires an installed browser – the browser also works offline. We suggest to use Mozilla Firefox (https://www.mozilla.org/pl/firefox/new/) – from experience it works best to open the app;
  4. The app can be downloaded here: https://dl.dropboxusercontent.com/u/3617370/D-ID_Workshop.zip. It’s 146 MB so the downloading can take some time.
  5. After the download is finished, please open the folder where it was saved (usually this is the “Downloads”, in the folder structure under folder [your username] under folder Users on your hard disk);
  6. To use the app we need to extract the archive, so we need a special software to do so, f.i. WinRAR (http://www.winrar.pl/winrar/pobierz ) or 7zip (http://7-zip.org.pl/);
  7. Click with right mouse button on the file and choose “Extract all”. Then chose a destination folder to place the extracted files. Default it will create a folder “D-ID Workshop” under your “Downloads” folder. Since the unpacked folder is 150 MB this might take some time;
  8. In your new folder you’ll see two subfolders: “D-ID_Workshops_AR”, where the AR app is located; “movies (session 5)”, where are 40 numbered folders: participants recordings can be placed;
  9. Open “D-ID_Workshops_AR” folder;
  10. Inside there are three key elements: AR markers in .pdf format to be printed (markers 1-40 in folder “Markers”), a video converter (“FlvConverter” file) and the app itself (“showcase” file); don’t worry about the FLARToolkit folder;
  11. Before using the app you need to print the markers from the “Markers” folder so each participant has one unique marker. Print them on A4-sheets, one marker per page;
  12. Now import your recordings into the app. Follow the instructions from the section “Instruction for the use of the conversion software for AR”;
  13. After we have printed markers and have imported the recordings into the app, we open the “showcase” file by double clicking on it;
  14. You’ll now see a window containing heads marked from 1 to 40;
  15. Click on the head marked 1;
  16. A new window will appear. If you will be asked for permission to give access to webcam and microphone, please click “Agree”. In the window we will now see the view from our camera. If you were asked for permission it is wise to right-click on the screen on which we see ourselves, chose “Settings” and select the “Remember” option – this way the software won’t ask for permission each time you open a new window;
  17. Marker 1 corresponds to head 1, marker 2 to head 2, marker 3 to head 3 etc. The recording of participant 1 corresponds to marker 1 and head 1. So the first participant will have to show marker 1 in the view that was opened by head 1 to evoke their recording in AR;
  18. Now test the app. Show the marker to the camera. Hold marker so that you don’t cover its frame with your fingers. Try to hold it parallel to the camera (don’t tilt it in front of camera). Try to hold it steady so the paper won’t bend;
  19. When you hold the marker properly, in its place the recording will appear. You need to hold the marker firmly to the end of the recording, otherwise the recording will stop;
  20. After the recording has been shown to the end, you click “Back” in the browser and choose a head with a different number;
  21. The app is very responsive to any sheet movement and light changes, so the app needs to be tested in the class room setting where it will be used during workshops to see whether it works well;
  22. It is good to have a uniform background in camera view when the participants are confronting themselves by means of the app. You’ll need to place the computer in such way that the light doesn’t shine directly into the camera and doesn’t light up the sheet with marker too much. Use all the light you can in the class room – it can’t be too bright for the app.
