| # Tool Area |
| # Raw width field measures approx. 1 unit per millimeter |
| # of tool area on the surface where a raw width of 1 corresponds |
| # to about 17mm of physical size. Given that the display resolution |
| # is 10px per mm we obtain a scale factor of 10 pixels / unit and |
| # a bias of 160 pixels. In addition, the raw width represents a |
| # sum of all contact area so we note this fact in the calibration. |

| # Pressure |
| # Driver reports signal strength as pressure. |
| # A normal thumb touch while touching the back of the device |
| # typically registers about 100 signal strength units although |
| # this value is highly variable and is sensitive to contact area, |
| # manner of contact and environmental conditions. We set the |
| # scale so that a normal touch with good signal strength will be |
| # reported as having a pressure somewhere in the vicinity of 1.0, |
| # a featherlight touch will be below 1.0 and a heavy or large touch |
| # will be above 1.0. We don't expect these values to be accurate. |
