Location and size coordinates can be specified with up to 3 bytes. The byte order in decreasing significance - big-
endian. For example:
• 1 byte: location x = loc-x-byte1
• 2 bytes: location x = (loc-x-byte1 << 8) + loc-x-byte2
• 3 bytes: location x = (loc-x-byte1 << 16) + (loc-x-byte2 << 8) + loc-x-byte3
Location is signed, and size is not.
The location coordinate scale is one of two systems, depending on which detector is used:
• Physical: Robair Air and Core detectors: The unit is 0.1 mm. A coordinate value of 463 thus means 46.3 mm
from origin.
• Relative: Triangles and Shape Air detectors: Fraction of the largest screen dimension as fixed point with 14
bits after the radix point (q14). On a widescreen display, the horizontal axis ranges [0, 2

2 * 9/16[ ([0, 16383], [0,

The zForce AIR Touch Sensor uses Robair, thus the unit is 0.1 mm.
Size is in mm.
Confidence and pressure is fraction of full in percent.
