1. Set up your own lab using Mr. Tappy, a ready-made
mounted device
You should have:
1. Mr. Tappy, a ready-made mounted device developed by Bowmast User
Experience and Design Research. Read about it at http://www.mrtappy.com/
2. 1 Logitech USB webcam.
3. 1 Hue HD USB webcam.
4. 1 screwdriver.
5. 1 Macintosh computer.
6. WebCam Monitor, the application that comes with the HUE HD webcam.
7. ScreenFlow, a screen recording application for Mac OSX.
How to set up your lab:
1. Build Mr Tappy following the instructions youʼll find inside its bag.
2. Attach the Logitech USB webcam to Mr Tappy using the tripod mount screw
and the screwdriver.
3. Mr Tappy requires you to stick some velcro to the back of the testing mobile
phone to attach it to its flat platform. Donʼt worry: you donʼt need to do that to
your phone. Weʼll give you a mobile with some velcro in it.
4. Plug the Logitech USB webcam to the Macintosh computer.
5. Go to the Applications folder and open the application called WebCam
Monitor.

2. 6. You should now see the image coming from the Logitech camera displayed in
the computer screen. This camera should point towards the mobile phone
screen.
7. If the image from the webcam is showing upside down, simply loosen the
camera screw and turn the camera around until the image displays in the
right direction.
8. Plug the HUE HD webcam to the Macintosh computer. You will use this
second webcam to capture your participantʼs face, so point it towards the
place where he/she will be sitting.
9. Go to the Applications folder and open the application called
ScreenFlow. ScreenFlow will display a small window to configure the
recording. Select the following options:
• Check the ʻRecord Video from:ʼ option and in the dropdown menu
select the ʻUSB 2.0 Cameraʼ
• Check the ʻRecord Audio from:ʼ option and in the dropdown menu
select the ʻBuilt-in Microphoneʼ
10. Do a test recording to make sure your set up is working. Someone from your
group should play the participantʼs role. When you are ready, click the red
circular button in ScreenFlow to start the recording, and ask the dummy
participant to play with the phone for a bit and say something to make sure
you are capturing audio. After a few seconds, press shift+command+2 to stop
the recording.
11. Click the play button in the ScreenFlow player to view the recording. If you
are happy with it, click the File menu, select the ʻExportʼ option, enter ʻtestʼ as
the file name and save the recording in the Desktop. Make sure you set the
Preset value to ʻWeb - Highʼ and the ʻScale byʼ option to 100%. When the
export finishes, check that the file plays properly and then close the
ScreenFlow player window.
Well done! Your lab is set up. You are ready to run a real test.
