This video will show you how to build the rig: http://www.youtube.com/watch?v=BrV3Zhp7gPQ&feature=plcp

1. Set up your own lab using a DIY mounted device
You should have:
1. 5, 6, 7 and 11-whole Meccano strips.
2. 2 Meccano trunions (the yellow pieces).
3. Meccano nuts and bolts.
4. 1 jubilee clip.
5. Some BluTak.
6. One USB extension cable.
7. 1 Meccano wrench.
8. 1 allen key.
9. 1 screw driver.
10. 1 Hue HD USB webcam.
11. 1 Philips USB webcam.
12. 1 Windows XP computer.
13. AMCap, and application that comes with the Hue HD webcam and allows
you to display more than one webcam feed on your computer screen.
14. Camtasia Studio, a screen recording and edition software. You can replace
Camtasia Studio with any other screen recording application able to
capture audio.
How to set up your lab:
1. You will build a phone rig using the Meccano, the jubilee clip, the BluTak
and the Hue HD webcam. Bernard will help you with that.

2. 2. Once the rig is ready and you have the participant’s mobile phone attached
to it, attach the USB extension camera to the Hue HD webcam and plug it
to the computer.
3. Plug the Philips webcam to the computer.
4. Double-click the AMCap icon on the Desktop. AMCap will open and show
the Philips webcam feed. This is the camera you will use to capture the
participant's face, so point towards where she/he will be sitting. Reduce the
size of the window a little bit.
5. Double-click the AMCap icon on the Desktop again. A second AMCap
window will open and show an error message. Don't worry about it: just
click 'OK'.
6. In the second AMCap window, which is all black, open the Devices menu
and select the HUE HD Webcam. You should see the Hue HD webcam
feed displaying on the AMCap window now. Point the webcam to the
mobile phone screen: you will see it is upside down. You will fix that next.
7. Open the Options menu and select the Video Capture Filter option. In the
Settings tab, check the 'Image mirror' and 'Image flip' checkboxes. Then
click the 'Apply' button, then the 'OK' button to dismiss the dialog. The
mobile phone screen should now display in the right direction. Adjust the
position of the camera to make sure you are capturing the whole mobile
phone screen and keypad (if it has one). Manually focus the camera by
turning the lens left or right. If the screen is too bright, reduce the
brightness of the mobile phone screen.
8. Arrange the two AMCap windows so that they are next to each other
without overlapping. You should have the face of the participant in the
smaller window, and the mobile phone screen in the bigger window.
9. Open Camtasia Studio. You will get a trial message: don't worry about it,
just click the 'Cancel' button.
10. Select the 'Record the screen' option. Make sure that 'Full screen' is
selected, 'Webcam' is off, and 'Audio' is on. Click the arrow next to the
'Audio on' button and choose the 'Microphone (Philips SPC 1000NC
Webcam)' option. It will give you the best audio you can get in this old
computer.
11. Give the phone to someone in your group to do a quick recording test and
click the big red 'Rec' Camtasia button.

3. 12. Play a bit with the phone and say something to make sure audio is being
captured. After a minute or so press F10 on the keyboard to stop the
recording. Camtasia will give you a preview of the recording. Click the
'Shrink to fit' option in the Camtasia player to see the full video on the
screen. If you are happy with the video, click the 'Save and edit' button.
Select the .avi format and save the video on the Desktop as 'test'.
Well done! Your lab is set up. You are ready to run a real test.
