Use of a laserpointer as control device
Note: This experiment is now obsolete. See Gesture based control using a Laser pointer and Image Recognition
I wanted to be able to control the videoplayback of the mediacenter (hooked
to my tube projector) without any extra remote control. The remote control
of the tube projector has a built-in laser pointer. I used a ultra-cheap
4 euro CMOS-camera and some self-programmed quick'n'dirty image recognition for the task.
The target with play/pause, file select, next, prev:
The target with the laserdot inside the previous box:
What the software sees thru the eyes of the crappy cmos-cam, notice the
very bright spot from the laser pointer (pictures cropped + strange jpeg artifacts):
Selecting buttons (no visual feedback to free some cpu cycles for media playback):
You don't have to aim before you "click". Just turn on the pointer pointing
somewhere random, and guide it to the box you want to select. Boom.

Can you open your program source?
Thanks,[ Dan | 15.12.06 18:02 ]
It would be really cool if you could open source your software.[ Arminius | 16.12.06 15:29 ]
Cool. Can i use this as remote keyboard? :)[ mnt | the codeninja, 16.12.06 15:38 ]
I made the mistake once to offer sources and drowned in support-emails of people that did not even have an compiler installed or did not know how to use the DirectX-headers.
No thanks.[ AzurusNova | 17.12.06 06:31 ]
Is there any particular software that could be freely avalible to fiddle around with and further develope on this?[ Tricky | 18.12.06 02:53 ]
This is sweet! Do you have any plans to release the code for this program, source or compiled?[ patliveground | 18.12.06 19:05 ]
a great trick would be to hook this up to a vhs or a DVD
go hackers go!!!!![ Varund | 29.01.07 06:27 ]
Nice one buddy! Did you use Matlab to simulate the program? It has some powerful algorithms and can turn the progie into C++ code too. I am just at the beginning of it, so when I come across something more productive to contribute, ill let you know. I think you can send in the sourse to a few people who understand what they are doing, since most of the times its the n00bs who download stuff and have no clue on how its installed/compiled.
Keep it going![ mnt | the codeninja, 20.02.07 00:13 ]
Matlab can generate c++ code? Nice.
