-==== System improvements ====
+==== Gadget/system improvements ====
 Andrés and Omar have been showing the gadget a lot lately, both at outside presentations and at open houses, so Omar has made a lot of small gadget-related fixes.
-(these all apply to the system more generally -- so the gadget is paying off for the normal ceiling systems as well -- but have been particularly acute or frequent with the gadget, because it has more tags at the fringe, it moves more, it has less RAM, etc)
+These all come together to make the gadget feel much more like the computational flashlight we want it to be:

       * does this break the projector?
   * Calibration not reliable?
+    * -> "camera occlusion seems to be a big problem (i don't really feel this but it could be the position from which I was presenting)"
+    * -> "My arms kept getting in the way. I think more than occlusion, the tag masking wasn't working great for some of the programs I had out and that was getting misinterpreted as being an occlusion problem."
+    * -> "yeah, if you're leaning hard on tag masking I think you need 1mm accuracy -- often I would say that tweaking exposure is the key thing (and there's a lot we could do in the UI to support making better calibration, too)"
   * Daniel: Would be good to pre-print:
     * Recalibrate card
