This wiki documents how to conduct a recording session with a test subject in the Rajinder (Raj) Koul Alternative & Augmentive Communication Lab located in CMA 2.266 CSD Research Lab #8.

CMA 2.266 Lab 8 has been outfitted with (3) data analysis carrels and an ADA-accessible subject testing workstation which will be used to conduct usability and outcome-based therapy testing for subjects (potentially wheelchair-bound) who use speech technology assistance devices. These testing sessions will be video recorded for post-test analysis. 

Set up before the Subject Arrives

Log into the PC at DESK-L84 using your EID and password.
Click <Window> > Blackmagic Design > Media Express

You can pin this App to your taskbar so it is easy to find

later by right-clicking on the App and choosing "Pin to taskbar"

In Media Express,

  1. Click on the Log and Capture tab
  2. Click on the ! button next to Name. This will force the program to prompt you for a filename each time you start recording. This avoids having a number of recordings named "Untitled 01"
  3. Confirm "V", "1", and "2" tracks are highlighted red and that you see the audio levels moving as you talk. Note that the audio levels are delayed by about a second. If you have on your headphones, you will also hear your voice delayed by about a second.



During the session

Click the Capture button to start recording.

When prompted for the file name, use this naming convention:

Last Name 2 Initials / First Name 2 Initials / Underscore / Year / Month / Day

for example, a subject named David Jaffitz being recorded on the 26th of July in 2018 would be:

JaDa_20180726

Using this naming convention causes all our files to sort alphabetically by subject and by date recorded.

Confirm you see the red arrow moving and the time on the recording duration advancing to ensure your recording is in progress

Click the Capture button to stop recording.
