# 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.
