Called <a href=\"http:\/\/web.media.mit.edu\/%7Eankit\/bokode\/\" target=\"_blank\">Bokode<\/a>, the system uses the Bokeh optical effect which maps how rays entering an out-of-focus camera lens will converge onto the camera&#8217;s sensor.<\/p>\n<p>To see the details, you&#8217;ll have to watch the attached video, but in essense the &#8220;tag&#8221; consists of an LED with an encoded optical pattern and a small cheap lens. An out-of-focus camera will see the data on the tag&#8217;s pattern, whether it is a digital code, an image, text or whatever. What&#8217;s more, the camera can also determine the angle of the object by doing some tricky optical calculations (which I don&#8217;t understand yet).<\/p>\n<p>The tech is still in the development stage, but there is a development <a href=\"http:\/\/scripts.mit.edu\/%7Eraskar\/bokode\/index.php?title=Bokode_Collaboration_Page\" target=\"_blank\">WIKI<\/a> to exchange information among those interested in working more with it.
