Calibration settings
|
|||||||
The
calibration dialog is used to set the calibration settings for the current
device. |
|||||||
Function |
Description |
||||||
|
Shows/selects
the current calibration style. Each device can have more that one calibration
style which can be calibrated independently. Calibration styles can be
invoked/switched manually, from an application, a toolbar or a command line
interface. A
number of style names have been reserved to cater for unique calibration
features as follows: Custom2point: Does not enter full screen mode
but the top left and bottom right corners of the calibration area are used as
the calibration reference points. RXXXXxYYYY: If XXXX and YYYY match a video
resolution (e.g. 1024 x 768) the driver loads the calibration data associated
with the style. RotateNN: If NN matches a video rotation
(0,90,180,270) the driver loads the calibration data associated with the
style. If using a 90,180,270 style then a 0 style must also be defined
and calibrated in standard landscape mode. The
above two style definitions are only required if the video display shifts
position in the new video resolution or rotation. |
||||||
|
Add a
new calibration style. |
||||||
|
Remove
the selected calibration style. |
||||||
|
Indicates
the number of calibration points. The number of points determines the
calibration pattern used. 2 points uses the raw pointer device data, 4, 9 and
25 uses a calibration algorithm best suited to non-linear data whereas the
other patterns are best suited to linear data. If the device supports
EEprom calibration storage, and the EEProm option is enabled in this dialog
then the number of calibration points available will be restricted to those
allowed by EEprom calibration. |
||||||
|
Indicates
the percentage margin in from the edge of the visual display area from which
to draw the calibration points. |
||||||
|
Specifies
the number of seconds to wait for a calibration touch before canceling the
calibration procedure. 0 = no timeout. |
||||||
|
If
shown implies that calibration data can be stored in the controllers EEPROM.
If enabled the calibration data is stored on the controller. In some case
this will effect the calibration options available. E.g. some EEPROM storage
procedures will dictate the number and position of the calibration points. |
||||||
|
If enabled
a calibration check dialog is shown at the end of the calibration procedure.
The calibration confirm button must be selected (with the touch screen!) if
the new calibration data is to be used. |
||||||
or |
Pre
UPDD 4.1.10 - If enabled a beep will be generated on calibration touch. |
||||||
|
UPDD 4.1.10 onwards - Configure calibration sound options. |
||||||
Once
the calibration settings have been defined as required the device can be
calibrated by invoking the calibrate option from the UPDD Console control
area, as shown below: |
|||||||
|
Invoke
calibration procedure for the current device. Calibration points are shown to
be touched. The ESC key can be used to cancel calibration if required.
Calibration will timeout if calibration points are not touched within the
specific timeout period. Note: When calibrating for the
first time in a multi-monitor environment all devices will be calibrated in
such a way as to also set up desktop / touch device relationships. |
