Equipped with: • Student PCs• 1 Projector Screen• 1 Teacher PC• The Teacher screen is projected to the Projector
screen.• Synchroneyes, which broadcasts a teacher station
screen image to student PCs and lock them down. http://smarttech.com/us/Resources/Training/Archive+Products/SynchronEyes+7+software
Ideas for the New AV Setup
• Multiple screens• Project not only the screen of a PC or a laptop but
that of other mobile devices.• Broadcasting & recording classes• Supporting hybrid classes with the audience in
this room and another site with full participation from both locations
• Camera and Mic• Speakers
Renovation• 5 Different screens in the room• 2 Cameras front and back• 1 Wireless mic & 2 Speakers• Touchpad control panel • A variety of dongles to hook up many different
mobile devices• Height-adjustable instructor desk• A/V rack in the closet• Flexible system that users can assign any input
(outputs from the AV rack with 1 video card with 4 different outputs) to multiple different display screens.
We (= IT) thought this was a very flexible,
powerful, and awesome system!
until
we had instructors test it.
Issue 1.The mouse wire and the keyboard wire
were too short.
Solution: Replace with the wireless
keyboard/mouse.
Issue 2.The monitor on the
teacher station would go to sleep mode and
wouldn’t wake up.
Solution: Mark the power touch button.
Issue 3.The teacher station PC would go to sleep and won’t wake up with the
wireless keyboard/mouse.
Solution: Disable the sleep
/log-off mode.
Issue 4.The arrangement of screens didn’t make
sense.
Solution: Make it similar to the extended screen setup of users.
Issue 5.Too many screens &
Tiny Mouse Pointer in the Sea of Screens
Solution: Powershell script for a keyboard
shortcut to retrieve the mouse pointer.

Issue 6.How Do I Turn On and Turn Off the
System?
Solution: Change ‘Power’ to ‘Shutdown’ on the control panel.
Issue 7.“Too complicated, can I
go back to the old school way?”
Solution: ‘Computer only’ display forces all screens to mirror the
teacher screen.
• Option to make the new classroom function just like the old one.
• High technology features unused.• But better than the room avoided!• Also works well with Synchroneyes that has
difficult with handling the extended display.

Issue 8.Presets did not fit
the use cases.
Solution: More presets for important use
cases & name them accordingly.
Issue 9.Terms on the control
panel are not intuitive.
Solution: Rename them.
Put labels on the physical devices.
Hard to Remember• Preset 1
oRear LCD, Projector, Lectern - PC output 4
o Front Left, Front Right - PC output 3 • Preset 2
oRear LCD - PC output 1 o Projector - PC output 4 o Lectern - PC output 4 o Front Left- PC output 2 o Front Right - PC output 3
Lessons Learned• When you, your IT staff, your IT vendor all think
the new setup is pretty good, you may need a reality check with non-IT folks.
• People do not want to deal with technology for its own sake. Technology should be in the background to get non-technology things done, teaching in this case.
• Confusing terms are confusing. Make them intuitive.
• Going back to the old simple setup is better than no one using the new setup.
• Revise how-to instructions based upon the user feedback.
• Your IT staff and users all need training, more than once!
