Learning Spaces Guidelines
AV & Teaching Station: 23
Where it is most appropriate to utilise a data/video projector as the
primary display technology care should be taken to ensure that:
for ceiling-mounted projectors that the stability of the image
will not be effected by footfall in the room above nor its
proximity to other services such as HVAC
for ceiling-mounted projectors that the filter can be
periodically cleaned, ideally without the need for specialist
access equipment
for wall-mounted projectors that the stability of the wall is
sufficient to render a stable image that will not be effected
by the closure of nearby doors etc.
In spaces where there is not space to accommodate sliding ‘column’
whiteboards, nor separate projection screen and a whiteboard
alongside each other, a hybrid projection/dry-erase board should
be used. In these instances the projector used should be of the
Ultra Short Throw (UST) type. UST projectors, whilst limited in
terms of maximum image size, have the benefit of not suffering
from a ‘hot spot’ reflecting back to users. In smaller learning spaces
UST projectors also have the advantage that the instructor will not
obstruct the projector beam if standing infront of the board nor be
dazzled by it.
Below is a table showing the advantages/disadvantages of different
learning space display solutions:

Security measures should be in place to protect the projector such
as an anti-tamper alarm or anti-theft bolt fixings.
