modFlosc is a modification for FLOSC, it allows you to create a virtual dead spot in your multitouch table. which is quite useful when you have a IR hotspot from your projector, we had a nasty blob in our setup caused by this hotspot, so i thought about a hack to avoid this area from the flash applications.
modFlosc basically works by taking in the coordinates for a rectangle, it takes in top left coordinates(x1,y1) and bottom right cooridates (x2,y2) and avoids the blobs detected from that area.
Following are the steps of how to use it
Step 1:
Run Tbeta or touchlib, background subtract, and you should obtain the irhotspot in the final detected image
Step 2:
- Run the file GET-HOTSPOT-COORDINATES.bat file
- Click Start
- You should be able to see a series of x,y,z numbers being detected
- These are the coordinates for the IR hotspot blob
- Here it is x=> 0.4921, y=>0.5167
- Note these values and close the modFlosc session and command prompt.
Step 3:
- Double click and open modFlosc.jar
- Now we take approximate values for (x1,y1) and (x2,y2) using the ir blob coordinates previously obtained
- The Red rectangle is the area which gets blinded
- Enter the approximated values into the modFlosc and press start
Step 4: If the blob still gets detected try increasing the range of x and y coordinates, which will in turn increase the size of the rectangle. that should do it
