A local video/projector business held a tradeshow yesterday with some
seminars from NEC, Epson, Smart etc. Some nuggets might be of interest.
Epson have a portable SXGA (1280x1024) document camera for about $500.
No backlit base; the camera (with light) just leans over the document.
NEC are saying that projectors are passÃ© and flat-screen displays ar
the way of the future. They are up to 80" (our projectors are set about
90" and maybe 120" in the auditorium), and they have a bezel-less display
one can tile (7mm between displays) to make big walls. Chained together
so one can drive them all from one video card, like at the airport.
Epson are saying that projector sales are up and will increase ...
One of them is saying the e-ink product will be here soon. Monochrome I
think - you write an image and it stays there with no power. Might
replace posters, advertising displays etc.
One of them is saying there will be flexible LED displays that you can
Someone was showing wireless "presentation remotes" that use a mouse
interface (no drivers required). Some have mouse functionality - a joypad
you can work with your thumb. I may buy one to play with, maybe for the
auditorium. The basic idea is you can do "next slide" without having to
use a table.
Memory sticks and SD cards for projectors seemed popular for road
warriors - you can put JPEGs on a card, stick in the projector, and show
slides without a laptop..
SMART were showing their smart whiteboard for use in a classroom. This is
a touch-sensitive screen or overlay with a magic pen tray, plus
application software. For K-12 their software looked quite impressive -
lots of drag-and-drop stuff. I believe there are packages for Windows,
Mac and Linux with progressivly less functionality (works as a mouse, at
the very least).
The screens come in various sizes for a projector (e.g short-throw
projectors that don't cast a shadow) also as overlays for common
flatscreen displays. They are typically smaller than our usual screen
size and would not work well with our tiled displays. The remote
presentation software is Windows-only and is not included in the basic
They also showed a wireless tablet, which I had not previously seen. This
has no display, just a writing surface so you can write on the smart
screen from a distance.
The basic functionality of the Smart board (being able to scribble on top
of a presentation or graph, save it to a file etc.) is included in the
tablet PC which I have available for load/evaluation, mentioned in a
