I glanced at the paper but I didn’t immediately see any references to latency. Am I missing something?

@Jarno:

The paper is available at:
http://www.cmst.curtin.edu.au/publicat/

It’s from 2007:
* Woods, A.J., Rourke, T., (2007) “The compatibility of consumer DLP projectors with time-sequential stereoscopic 3D visualisation“, presented at Stereoscopic Displays and Applications XVIII, published in Stereoscopic Displays and Virtual Reality Systems XIV, Proceedings of SPIE Vol. 6490, San Jose, California, 29-31 January 2007.

Hello Bor,
I would be very interested to have that list as well, might it be possible for you to send it to me?

Or perhaps anyone else has it?

thanks laurence – no problem

can you tell me the model of the firewire camera?

hope things are going well!

Hey Kevin, unfortunately I did not do any latency measurements between the Firewire camera and the USB camera.

do you have any latency metrics for the “new firewire camera” (model?) vs the phillips spc900nc?

i’m looking for a low-latency camera

thanks!

I’ve worked several years developping stereoscopic applications… I have a list of projectors and their latency. I will send it to you.

interesting concept about the latency and projectors…the greater latency on short throw kind of makes sense though. i think 100ms is unacceptable user input delay for anything in real-time…

@gravano 2nd post.

I do agree that snapping the photo tile on every area would make the game more interesting.
About the dragging, when you’re using a multitouch table or the TUIO simulator tiles will be moved to the top layer. When using a mouse this does not happen, I’ll see if I can fix that .

Nice work I have some BLMT improvements for you.

Check your email.

maybe an idea to have the pieces that you drag as the top layer, because right now they are floating under the piece that you have put in the correct area

another thing I would apply is snap an piece of the photo to every area, even if it is not the right area, coz else you just drag it around the screen and let go of it at every area, which is not that exciting

in that case you would need the pieces of the puzzle outside the frame you are going to put them in if you know what i mean

i like the different stages of difficulty

keep up the good stuff

interesting! nice to see you started the topic on nuigroup, think it will be very useful!

the puzzle game looks really nice, gonna try it out now
