Thanks all ^^

Now that is a cool project. Kudos Sittiphol!

Great work, kind of similar to what Johnny Lee made using the infra red sensors, and wii remote, great that we have similar made available for our N95's.!

Excellent.

I have been toying with idea of doing a project using light as a positional aid to allow the phone to be positioned in space for while. Too slow!!!

But very nice work

Decisely impressive!!

Really nice work!!!

Really nice, it looks good!

Shit i'm really impressed with what i see. I think this can start to be a usefull addition for mobile phones as a presentation device. Cool work guy's

There seems a bit of a lag but otherwise it works!

Why do you need the "pen" ?

On Television the Weatherman uses just their finger and a "black-box" detects the smallest point furthest away (tip of finger) and makes that the active spot.

Your program does not need to use light from the pen. You can use just your finger. To make it easy paint a thimble green and stick it on your finger, then have the camera look for green.

Also make camera correct for "keystone" them you can move camera off to the side and out of the way.

You also need to make it work on white piece of paper (with NO Television). You hold camera (phone) in one hand, look at screen, draw on paper with finger and see result on phone's screen.

Once you get rid of the light-pen and the Television this will be portable (and popular). With character recognition and the ability to draw on cement (or blacktop) instead of white paper you can make easy to use "keyboard" for texting quickly.

Keep up the good work.

Hi Rob_C,

Thanks a lot for your suggestion. :)

The main reason that why I didn't track finger directly instead of track the light pen was N95 CPU is too low to make full image processing. For now, it can operate at only 5 fps (320x240x24bpp) with high optimization.

However, I will try my best to make it more usable than now. May be the way to write on the white paper with finger.

Thank you once again. :)

Good work ....

Its really interesting! Great work! :)

Regards
Gopal
