Computer Coordinating Area Curvimeter

I mentioned before about the area measuring device right? see th pictures bah. It's fatisnating to me. ha.

This is the picture of the whole device, I use this to measure the area of each room which requires air conditioning. so that we can size up the air con.

So we use this MANIFYING pointer and "DI" "DI" "DI" the perimeter of the area, any strange odd area also can, no problem one, curve, straight, anything also can.

After the area is closed, it will "DI-DI" and HEY PRESTO! we can get the area and the perimeter through the LCD screen.
