Basic Guide to Projection Facilities in Large Classrooms

Which Rooms

The following rooms have computer and video projection equipment which make use of basically the same equipment and hence offer a similar environment.

Individual variations in each room are discussed below.

What Kind of Projection Equipment

With one exception, all projection devices are 3M 8030 LCD projectors which operate at a resolution of 640x480 but can also acccept 800x600 in compressed mode. For most applications, especially Netscape, the 800x600 mode will be quite good although all applications will look best in the native 640x480 mode.

Each LCD projector also accepts regular video and S-video input for video projection.

The projector is located so as to maximize the image size on the available projection surface. This means a 25 foot diagonal image which assures adequate viewing even in the back of the room. Each projector has a remote control to switch between either computer or video input as well as to turn on, focus and zoom the unit.

What Kind of Computer is Available

The basic networked platform which is available in these rooms is an IBM Thinkpad model 760-ELD (\eg a laptop). Each of these is equipped with the following:

Network connectivity and IP addresses will be accomplished when the PC is turned on and accesses the DHCP server (this should be transparent to the user). It is recommended that the faculty member who wishes to project networked applications (e.g. Netscape) makes use of the ThinkPad. We anticipate, however, that many faculty members will want to run their own applications and software. The easiest way to facilitate this would be if the indvidual faculty member has access to either their own laptop or a departmental laptop. All necessary cables are already present in the classroom. When this option is not available arrangements can be made (probably with the IMC) to install the software (see more below).

What do I have to Fiddle With

Because the ordered furniture (lecturns) have not yet arrived the final room configurations don't exist yet. The ordered furniture looks like this . As such, there is no good way to yet secure the laptops and hence they will be available on a checkout basis.

There are 4 things the faculty member must do to enable the system:


The laptop has a stiff trackball for its pointer. We anticipate this will be difficult to manipulate for a point and click presentation and hence will provide an external mouse (which you need to plug into the external mouse port on the side of the laptop prior to turning it on). We have two radio controlled external mice which will free up the instructor from having to be near the laptop during the course of a lecture. We will probably order more of these.

The Function F7 key on the lap top will send the video to the external projection device and can also display it simultaneously on the laptop or only on the lap top. The switch toggles between these modes. Pedagogically, it is a very bad idea (unless you are needing it for diagnostic purposes in which case you shouldn't let the class see what your fiddling with) to have a simultaneous display because most times the lecturer ends up talking to the monitor. It is much better to look at what the students are look at in the same way that one shouldn't lecture by looking down at an overhead projector. Use of the remote mouse means you can wander around the room. Any presentation which requires a lot of keyboard typing is a bad idea.

How do I turn everything off

Who To Blame for All of this

This is part of a long term project to upgrade our classrooms. This junk was paid for my the physical plant. The project was coordinated by Greg Bothun, Andrew Bonamici, John Chappell and Dale Smith. Send complaints or suggestions only to the first of the named individuals using this link

This upgrade project cost around 100K. We hope faculty use it and we would appreciate some documentation of this use. If no one uses the equipment (we care aslo about straight video projection, not just computer stuff) there is no reason for future upgrades.

Lighting Conrols

Each room is designed to have lighting control that does one of 3 basic functions:

The lighting control part of this project has not yet been completed in all cases. Please refer to the room specifically below.
