For each test user, there are two full-length videos: one from the external video camera and one from the session capture on the device.
Since the full video files are too large to upload, you will hand these in separately on a USB stick, together with scans of the signed consent forms, and a file containing a mapping of the test user's real names to their TPid and first name alias. These files will not be released or published.
The short video clips illustrating findings, with blurred or pixelated faces, are considered to be part of the TA Report and are uploaded with the report.
Obtain a USB stick, 16 GB should usually be sufficient.
Format the stick as NTFS or exFAT.
Make a directory gT-XX-ta-full-videos, where T-XX is the number
of your tutor and group. For
example, g1-05-ta-full-videos for Group 1-05.
Our preferred video format is MP4 (H.264 video with AAC audio).
If your external video camera does not record in MP4 with the above
codecs, we will try to play any of the following formats: MPEG-4 with
other video or audio codecs (.mp4), MPEG-1 or MPEG-2
(.mpg), QuickTime (.mov), Matroska
(.mkv), and WebM (.webm). Please do not use
any obscure or proprietary video or audio codecs.
If we have difficulties playing your external video files, you may have to convert your videos into a different format and hand them in again.
Create a subdirectory external-videos containing the five
full external videos from the tripod-mounted external video camera,
one per test user as follows:
gT-XX-ta-full-videos/
external-videos/
tp1-ext.mp4
tp2-ext.mp4
...
tp5-ext.mp4
Export the full session capture video for each test user as MP4 (H.264 video and AAC audio) in no larger than FullHD (1920×1080) resolution.
The full session capture video should include the user's audio and unobscured facecam.
Create a subdirectory session-videos containing the five
full session capture videos, one per test user as follows:
gT-XX-ta-full-videos/
session-videos/
tp1.mp4
tp2.mp4
...
tp5.mp4
Scan the signed consent forms as PDF, in colour if appropriate.
These must be scans in reasonable quality, a photo is not acceptable!
Fill out the file users.html so that it contains the
mapping of the real names of the test users to their TPid and first
name alias.
Create a subdirectory private containing the five scanned
consent forms and the file users.html as follows:
gT-XX-ta-full-videos/
private/
tp1-consent.pdf
tp2-consent.pdf
...
tp5-consent.pdf
users.html
Your directory structure should look something like this:
gT-XX-ta-full-videos/
external-videos/
tp1-ext.mp4
tp2-ext.mp4
...
tp5-ext.mp4
private/
tp1-consent.pdf
tp2-consent.pdf
...
tp5-consent.pdf
users.html
session-videos/
tp1.mp4
tp2.mp4
...
tp5.mp4
Copy the entire directory gT-XX-ta-full-videos
onto the USB stick to hand in.
Label the USB stick with "HCI 2023" and your group number "GT-XX" using a sticky label (and small writing!).
Bring your USB stick with you to hand in at the third client meeting (M3).
Unfortunately, I am unable to return the USB stick to you. A 16 GB USB stick now costs around €3 (check at Geizhals), i.e. around €1 per group member. I think that is not unreasonable, especially considering the time and effort it would take me a) to copy all the videos over to alternative media and b) to organise dates and times for you to collect your sticks.
The USB sticks you hand in will be securely erased or destroyed one year after handing in.
Set a reminder, so that you remember to delete your own copies of the personal data of your test users (full video recordings, scans of signed consent forms, mapping of real names to IDs and aliases), including any backups, one year after handing in.
Keep your own local copies for at least six months in case there are any issues with reading your USB stick or appeals regarding grading.
