For our clients, we use a sled with three cameras attached: face, screen, and keypad. These are tiny security cameras with different lenses on them. We run the three cameras, plus a wideshot camera, into a portable quad mixer (targeted at the security folks, again, but works fine for us). We then record the four images. Synchronization is very difficult. My photo specialist explained it to me once, and I don't have it fully integrated. The explanation included the fact that different cameras run at slightly different speeds, causing mismatches to accumulate. I've got a presentation up on slideshare on usability testing, it includes some pictures of different setups. http://www.slideshare.net/barbaraballard/mobile-usability-testing -- Barbara Ballard [EMAIL PROTECTED] 1-785-838-3003 ________________________________________________________________ *Come to IxDA Interaction08 | Savannah* February 8-10, 2008 in Savannah, GA, USA Register today: http://interaction08.ixda.org/ ________________________________________________________________ Welcome to the Interaction Design Association (IxDA)!
