Ethics and video capture

UWIC Application for Ethics Approval
I have recently submitted an Ethics Approval Form to the Schools Ethics Committee to obtain permission to approach the public to capture video as well as observe and record users emotional response to the 'wall of video'. We are awaiting the Committees decision.

PHOTOGRAPHIC and/or VIDEO RELEASE FORM for research purposes
I have also written a video release form which asks subjects to sign the following statement... "I hereby grant permission to use any and all photographic imagery and video footage taken and any audio recorded of me on the date entered below, without payment or any other consideration. I understand that such materials may be published electronically or in print, or used in presentations or exhibitions. We will have to create something similar when we observe users experiencing the game."

Video Capture
The game needs 32 video clips to build the grid. They need to be captured in varying lighting conditions and with a range of gender, ages and race. This variety is essential to convince the participant of the game that they have been randomly captured by the game.
I have developed a method of creating short seamlessly looped video clips in order that they appear to be live.

1. Capture
Subject to remain still with minimum movement of body and arms but with a focus on recording breathing and blinking together with small head movements in order to convince the user of live feed video. 30 seconds are recorded whilst the subject watches a digital clock in the center of the screen. I have been using the iSight camera built into an Apple MacBook Pro laptop running iMovie software.

2. Edit
Select 6 or 7 seconds of video and repeat it in the timeline, reversing so that it becomes a seamless loop.

3. Export
Quicktime files are created at 160x120 pixels. No audio is included. Matt Leighfield compresses the file with Visual Hub and inserts them into the grid.
