I updated the W2TUIO application (key handling now corrected). Enjoy - still looking for more multitouch applications that will run on this great platform.
I’m still having trouble with false touches can seem to shake the problem and it hasn’t gotten better with the older ntrig driver. I’ll hope for more stable ntrig mt driver.
I didn’t rollback to older drivers - the problem is not appearing that much on mine lately. Conversely, I had emerging issues with the display driver (weird crashes, blackouts and delays in responses). Oh well, this is Beta-land......
A question to all those TUIO developers: In MT flash clients, the following touch info is displayed: ID, X, Y, A ==> what does the “A” mean (cf my initial snapshots) - acceleration? or contact area? Doesn’t really map to TUIO protocol elements....
@cerupcat:
???? I used 2Dcur profile specification as given at : http://mtg.upf.edu/reactable/?tuio “ /tuio/2Dcur set s x y X Y m “
from the other parameters on that page, motion accellaration is mentioned (scalar value? what use is that?) . However, I cannot find specifications for height or width (blob size? Hey I was looking for that as W7 Touch events do specify these).
BTW I am considering using the same protocol for Augmented Reality purposes (employing ARToolkit http://www.hitl.washington.edu/artoolkit/). BUT I’d rather have good, solid transformation matrices for 3D samples than euclidian angles (a pain in converting back and forth and lots of boundary conditions) . My strategy for now is to resort to plain OSC. A pity.....
can anyone confirm this will work on th HP TX2? are there any reasons to go with the dell xt? I want to buy one right now to work on this and adapt W2TUIO to an interface I made. The latitude seems a little on the slow side… small proc, small drives, generally slow configuration… the hp seems faster…
@ke: yes I am also interested whether HP TX2 owners can run this applet. In principle, it should be possible as n-trig releases similar beta drivers for this platform.
The only issue _might_ be calibration - people facing this problem please contact me and we can solve this in a few minutes…
I agree that performance wise, HP has better specs. However, the BIG advantage of the XT (and arriving XT2 now announced through gottabemobile.com ) is weight (1.7 kgs vs >2.2 kgs this is noticeable!). Plus availability of slice battery (HUGE PLUS in mobile environments!).
Hello joukev.I was really excited by your work while waiting for my HP tx2 to arrive.Now that it has I have a problem.Multitouch is not working
I am using Windows 7 beta with N trig beta drivers that support multi-touch,I’ve downloaded all the files;switched to Windows 7 Basic;started osc,maximized flash demo and started the tuio app but it still doesn’t work.I think the tuio registers the number of fingers I am using but it doesn’t register my input in the flash app.Can you please help me?
@UPDATE.Restarted PC did all that again and it works fine now.This really hs potential but does anyone know if there are any multitouch synths being developed that mimick the functionality of the kaoss pad?That would kick major ass..
Just got my XT, given that MT is also present in Vista, is there anyway to test these apps or still stuff within Vista, without upgrading to Win7...cheers
@Osiris: afaik the anwer is still negative. cf my post #41 (http://nuigroup.com/forums/viewreply/26527/). MT in vista is actually dealt on device-level and converted into regular pen/mouse/scroll events (N-trig applet etc) , while in W7 a true implementation of TOUCH events is supported by the operating system. The only ones that could enable better Vista MT behavior are n-trig themselves. I would give it a shot if I would have sources of the device drivers+firmware.
