Adding a graphics layer for computer presentations

[LARRY NIEBUR <lniebur@INS.INFONET.NET>]

I have seen tablets that can be connected to a computer that will allow a
graphical layer to be added to a displayed image so that circles, underlines,
arrows, etc. can be used for emphasis.  They seem especially effective when
color graphics are drawn for emphasis while displaying the image on a
big screen to present to a group of people.

I know Minnesota Western sells an LCD display panel with this option, and also
sells a graphics tablet by itself to use with lcd panels from other vendors.
They definitely are on the expensive side.

Will all who are familiar with this type of device please share their
experiences, costs, and sources for purchasing or getting more information?

TIA!

Larry
