Hello All,

I want to know if anyone used TrackIR for interactive whiteboard setups like Johnny Lee's wiimote based solution.

The posts are usually about using wiimote instead of TrackIR for gaming purposes but I couldn't find the opposite: using TrackIR instead of wiimote for interactive whiteboard.

If you tried this, can you tell how it did perform? If you didn't try this, can you tell me where to start? Which SDK should be downloaded? Is TrackIR right for such project?

Any thoughts are appreciated, thanks.

It's possible that you could use the TrackIR in this sort of application. The OptiTrack Camera SDK has the capability of getting the appropriate information from a TrackIR, however please keep in mind that as it is outside the bounds of it's intent, technical support for TrackIR in the Camera SDK is not generally guaranteed. However, if you were to use the Camera SDK with an OptiTrack camera, we are available for technical assistance.

Thanks Mike.

Does TrackIR provide the coordinates of the IR light sources or does it stream each frame and let the PC find the coordinates?

If it does stream the frames, where does the "resolution enhancement" occur? In driver or in TrackIR itself?

One last question: Does the camera SDK has built-in tracking library or I have to code it?

The Camera SDK will stream frames of data from the TrackIR. Those frames contain the X,Y locations of each retro-reflective or IR light source as well as other information. Additionally, you get the frame buffer if you'd like to display something for the user.

The resolution enhancement refers to the quality of the X,Y locations which have sub-pixel accuracy.

The Camera SDK does have a build in tracking library that can track the vector clip or the track clip pro.
