Using one Tablet to Drive another ?

[dave_newell]

AT our school we have fixed tablets at the teacher desk hardwired to a video projector. We would like to allow pupils to drive the tablet and use Windows Journal. At the moment they have to come to the front of the room to present. We are testing a Wacom Wireless pen tablet that can be passed around the room but the students cannot see what they are writing without looking up.
Is there a better way ?
i.e. what suggestions are there for having a 2nd tablet PC pased around the room and using the write on screen to control the teachers' Tablet PC

Does anyone have any experience to share ?

Hey Dave, I found a nifty program called "tableau" that vin essentially transfer your mouse movements and clicks to another computer.

You will not have pressure sensitivity, though.

tableau is EXACTLY what I've been looking for for ages! :) thanks triple_dude.

unfortunatly i wish it supported absolute positioning (where pixels on the tablet would be mapped to the big screen in the same position) and right now brushing in photoshop gets a very jaggy line... i wonder if using a ethernet cable to network both computers increases the quality of the line.

I ask my self why there isn't a app out there with all these features by now.

The reason why the lines are jaggy is because there isn't sub-pixel precision when the pixel data is transfered over.

So the network speed is not the culprit.

There is also a way to get absolute positioning by using VNC's (try TightVNC for a spin if you're a keener ;)) and simply mirroring the screen of the slave computer on your master tablet PC.

Unfortunately, there doesn't seem to be a way to simulate pressure sensitivity on a computer (I've been looking for ages and haven't come across anything viable), even though I can obtain the current pressure of the pen... If there's any programmers out there who knows how to simulate the pressure sensitivity of a pen instead of simulating a mouse click, then please give me a shout!
