be used to test for a flexed (closed) gesture, and the minimum value of the two
will be used to test for an unflexed (open) gesture.

6.8. Auto-Calibration

The driver can provide sensor outputs in an automatic, linearly calibrated
fashion. During every update, the raw value read from the sensor is compared
to the current minimum and maximum raw values (raw

min

and raw

max

) as set by

the functions

fdSetCalibrationAll()

,

fdSetCalibration()

or

fdResetCalibration()

. If the current minimum and maximum values are

exceeded, they are overwritten. The upper and lower calibration values are
therefore continuously pushed "outwards". The normalized output is given by
the first order equation

,

.

val

=

(F-1)

which is in [0...Max]. The value of Max is set by the functions

fdSetSensorMaxAll()

and

fdSetSensorMax()

. Doing a few flexing

movements with the hand quickly sets the operating values for

raw

min

and

raw

max

, and calibrates the glove.

The auto-calibration process can be ignored by simply regarding only the raw
sensor outputs. It would be up to the application developer to provide a suitable
calibration process.

Note that calibration is mandatory, especially with the high-end gloves

which contain no hardware calibration possibilities.
