Hitachi CP-TW2503 Projector Review - Interative Setup & Use

Posted on August 27, 2014 by Jarrod Buckley
HITACHI CP-TW2503 PROJECTOR:  Setup and Use of the projector's Interactive Features, called IWB by Hitachi, are described in this section.

Hitachi refers to the interactive functions as IWB, which may stand for "Interactive White Board", but that's just my guess.

Before the IWB function can be used it must be setup and that can be done through the projector's Advanced Menu (shown below).

From this menu select "IWB Mode" and from the IWB Mode menu that is then displayed, as seen in the photo below, turning on the IWB function with the desired  operating mode (i.e., either standalone or connected to a computer) and for the specific video input being used (e.g., HDMI-1, HDMI-2, etc.).

Note:   Once you have completed this initial setup of the IWB function you can select the IWB Mode, including turning IWB on or off,  for the current video input by pressing the IWB button on the remote.

Next the interactive pen location must be calibrated to the screen positions.  This can be done using automatic calibration or manual calibration (see IMB menu below).  Note that the automatic calibration function is only available when the projector has been connected to a computer, via HDMI or VGA and also via USB, and set to operated in the "with PC" IWB mode (see above).  Manual calibration must be used when the projector is operated in "standalone" IWB mode.

When manual calibrate is selected, the projector displays a series to 16 calibration images with each having a "bullseye" target (as shown in the photo below) that the user must touch the tip of interactive pen against.  Each screen has one point indicated and the 16 images identify 16 calibration points placed in a 4 x 4 grid across the screen surface.

Note: After doing the manual calibration, I found the accuracy of the light pen position relative to the image to be excellent with under 1/2 inch difference between drawing location and the actual pen position.

Finally, when you are ready to start to use the IWB function for drawing (I used the standalone mode) you can popup the drawing menu, as shown below, to select such things as line drawing and color.

Finally you are ready to go.  The projector is supplied with two pens and up to four total can be used at one time, meaning up to four people can the drawing on the whiteboard at one time.  Below is an example of my simple line annotations over one of our standard test images.
