    <p>In a multi-touch environment, how does gesture recognition work? What mathematical methods or algorithms are utilized to recognize or reject data for possible gestures?</p> <p>I've created some retro-reflective gloves and an IR LED array, coupled with a Wii remote. The Wii remote does internal blob detection and tracks 4 points of IR light and transmits this information to my computer via a bluetooth dongle. </p> <p>This is based off <a href="http://johnnylee.net/projects/wii/">Johnny Chung Lee's Wii Research</a>. My precise setup is exactly like the graduate students from the Netherlands displayed <a href="http://www.cs.rug.nl/~isenberg/VideosAndDemos/Vlaming2008PTI">here</a>. I can easily track 4 point's positions in 2d space and I've written my basic software to receive and visualize these points. </p> <p><a href="http://i40.tinypic.com/x517yg.png">alt text http://i40.tinypic.com/x517yg.png</a><a href="http://i42.tinypic.com/nao9x.png">alt text http://i42.tinypic.com/nao9x.png</a><a href="http://i43.tinypic.com/65d1zp.png">alt text http://i43.tinypic.com/65d1zp.png</a></p> <p>The Netherlands students have gotten a lot of functionality out of their basic pinch-click recognition. I'd like to take it a step further if I could, and implement some other gestures.</p> <p>How is gesture recognition usually implemented? Beyond anything trivial, how could I write software to recognize and identify a variety of gestures: various swipes, circular movements, letter tracing, etc.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
