Community Software Update

Taha Bintahir and Paul D'Intino release touchWorldWind beta:

This enables multi-touch in Nasa World Wind which lets you zoom from satellite altitude into any place on Earth. Leveraging Landsat satellite imagery and Shuttle Radar Topography Mission data, World Wind lets you experience Earth terrain in visually rich 3D, just as if you were really there. Virtually visit any place in the world. Look across the Andes, into the Grand Canyon, over the Alps, or along the African Sahara.

This multitouch plugin is designed to provide a more Natural User Interface, where the user can naturally navigate through the environment using standard predefined gestures. This plugin allows the user to pan, zoom, rotate and tilt the globe, and lets you experience Earth terrain in visually rich 3D.

Georg Kaindl releases Touch'e Beta 3:

First (and probably coolest) is native support for the format the NUI Group Flash demo apps use to receive tracking data (e.g. it’s outputting the format that tools like “flosc” create from TUIO output, but doing this directly in the app, obviating the need for the adapter server). This means that using a Flash demo with Touché is now as simple as launching Touché, then launching the Flash demo - it will connect to Touché automagically, without having to worry about anything.

Also, you can now (optionally) choose a thresholding filter based on distance from a reference color. This is very useful if your touch blobs are not necessarily brighter or darker (luminance-wise) than the background, but have a distinct color instead. Alternatively, you could use this to “abuse” Touché into being a color marker tracker for non-multitouch projects.

Another new thing is the ability to specify a maximum blob displacement between matched blobs in two consecutive frames, which is useful against the not-so-rare (especially if you’re using a camera at about 30fps or less, and multiple people are working on the multitouch table simultaneously) case that a finger is lifted off in the same video frame that another one is put down - if the blobs’ distance is larger than the threshold, they will not be matched, but a “touch up” and “touch down” call will be delivered instead. If you find that this is causing trouble with very fast motions, you can make the threshold higher (or lower, if the issue described in this paragraph still pops up).
