How to do Sanako Oral Exams with large classes, but few licenses: A workaround using partial classroom layouts

When you open the Study1200 tutor, a dialogue comes  up which lets you select you the “classroom layout’. What this actually means – since the physical classroom (LRC layout) is obviously immutable –, is: which computers do you want the Study1200 to connect.

The “template classroom” (this happens to be just  the default name within Sanako) tries to connect all students logged in on computer in COED434  to the teacher from the “corridor” (= where Study1200 leaves all computers that it knows of, but that you do “into” want to let into the classroom; the corridor has link in the bottom center of the Study1200 teacher window, and it flashes if there is a change “in “ the corridor Stuy1200 wants to make you aware of) that the Study1200.

However, beyond the 20th client (first come, first serve), this will fail because of licensing restrictions, and a grey exclamation mark will appear in the classroom layout in the Study1200 window for these student icons.

The “left-half”and “right-half” layouts that I created load only the computers in either the left or right half of the COED434 classroom (each without the wall/window-facing computers at the very edges) into the classroom layout (other logged-in students will remain in the “corridor”, linked in the bottom center of the tutor interface, if you want to add select students – note that the student icon will not appear on screen in their approximate physical position in the classroom.

You can also bring up the dialogue from which you can choose classroom layout after the initial startup of the  tutor: Go to top menu: file / classroom layout. A 45-second screencast of this switching  our classroom layouts in Sanako Study 1200 is available for download (requires Windows Media player).

In the screencast, you can see how the visual layout on screen reflects the physical layout in the classroom (the number labels on top of our computer monitors appear (optionally) in seat numbers): rotate by 90% clock- or counterclockwise (I wish we would have not only more licenses, but also a higher screen resolution. Stay tuned).

This technique of splitting the classroom, unloading and loading half of it at a time, you can exploit for administering oral exams consecutively with class sizes (current maximum is 25/30, depending on level) that exceed the number of licenses we have (currently 20 + teacher).

This technique of excluding computers from connecting to the teacher we could also use to merge the listening station computers, even though they have a different audio hardware configuration (analog headsets only, no Sanako headsets with built-in sound card and disabled on board sound) into the main software image without consuming valuable licenses – not without other problems.

How to configure a re-imaged (syspreped) Sanako Lab 300

2009/09/17 1 comment

1.    On each of the 30 student computers in the main lab MH441, log in as user “llc-staff”.

2.    In the Windows taskbar, click “start”, “run”, type: “c:\Program Files\Sanako\Lab\Lab300\duo\config.exe”, click “OK”.

3.    In the “Media Assistant Duo” window that opens, change the field “Workstation number” to the last (one or two: omit leading zeros) digit(s) of the white label at the edge of the monitor that you are working at:

4.   

5.    Click button “Finish”, then restart the computer.

Bonus hint:

If your lab goes down again in the middle of the term, check whether your IT department has set up new computers on the sub-network whose network names conflict with the Crossroad naming scheme of the Sanako Lab 300, as seen in the above dialogue and set in the Lab 300 crossroad settings dialogue. 

Digitization of the SAVILLE analogue Conference interpreting recording facility: Lecture/Floor recording and CCTV streaming

The original conference interpreting lab setup had no provision for digital video recording of the lecture/floor. A workaround used on of the booth VCRs for analogue recording, with video form an ELMO dome cameras and audio from a lectern microphone – an audio installation which ran in parallel to the main DSI conference interpreting facility (and covered only the lectern, not the conference table).

A home-brew add-on was based on a consumer handheld digital camera for video. Experiments with different add-on microphones for audio from the lectern and floor were less than successful.

The DIS system however provides an audio out of the lectern an/or floor audio, as well as the capability for the conference administrator to open or mute floor microphones and for the technical administrator to set the maximum number of open microphones, and control their gain.

For the digitization of this system, I used

  1. an already retired standard university student lab computer
  2. to which I added an old spare ATI All-in-Wonder video card
  3. to which I connected a TEVION home TV switch as a poor man’s (~5£) video splitter into which I fed
  4. the (hitherto unused) DIS audio out balanced stereo, using an RCA adapter, as well as
  5. the ELMO video, using  a coax to RCA adapter (video signal was split into the ATI as well as back into the original SAVILLE Kramer AV switch).

While originally coming with its own digitization software, the ATI All-in-wonder also works well with Windows Media Encoder.

Two wme configuration files were created:

  1. capturetestaticomposite_pal-l_480x320works.wme(find this file on the computer connected to the central rack, then double-click it in order to start Windows Media Encoder, then click the Record button in the top menu – no custom GUI was deemed necessary for this non-student operated recording)  for recording to files that can be played with Windows media player, whether on Windows or on Mac OS X.
  2. streamtest480x320_15fps_pal.wme (again, simply find this file on the central rack computer, then double-click it) for streaming CCTV live to the back office. An onsite admin office was one of the usual features of a teaching lab which was missing in this installation. CCTV allows to keep an eye on teaching activities in the conference interpreting lab, proactively spot support needs ands absorb feature requirements which instructors tend to have problems articulating (or even seeing the need for articulating).
