Tablet Mapping

Tablet to Display Mapping

This is atopic for MovALyzeR.

The procedures and tests for display mapping options for various tablets are described in this section. Perform all the different tests to completely understand the procedure.

* Driver Settings

* MovAlyzeR settings

* Printing Elements/Stimuli Real Size


Driver Settings

First verify the driver properties: Control Panel > YourTabletDriver (Eg., Wacom) > Properties > Mapping/Speed tab.

o Reset all to default values if you have previously changed some settings (for Wacom tablets: click 'Reset Tablet to default').

o Verify that the entire tablet is mapped to the entire display and the aspect ratio is to-fit.

In Wacom: Tablet area = Entire tablet; Display Area = Entire Display; Aspect = Proportional; Orientation = Landscape.


MovAlyzeR Settings

Since the Wintab Driver does NOT pass its mapping properties on to MovAlyzeR, any kind of mapping must be done ONLY in MovAlyzeR.

MovAlyzeR > Settings > Select Input Device > Tablet Mapping

A. Choosing the Tablet area

o Specify the width and height of the display in cm.

o Tablet width and height: The height and width of the portion of the tablet to be used, measured from the bottom left corner of the recording window.

1. To use the entire tablet, specify the original width and height of the tablet.

2. To use a portion of the tablet, specify the size of the tablet as the area required instead of the actual area.

For example, suppose the actual size of the tablet is width =12" and height = 12". If a mapping of tablet width = 12" and tablet height = 9" from the bottom left corner is needed, specify 30cm (12") and 22.5cm (9") in Tablet size boxes.

Effectively you have a tablet mapping as below:

NOTE: MovAlyzeR will read only the mapped part of the tablet.

B. Mapping Options

NOTE: In this section, the term 'Tablet' will refer to the tablet area mapped as in the section above (Entire or Portion).

1) Tablet to Entire display

Settings: Choose options 'Entire Desktop' and 'Proportional' > click ok to save and close.

Corresponding Experiment Settings:

Test:

2) Tablet to Recording Window

Settings: Choose options 'Recording window' and 'proportional' > click ok to save and close.

The entire tablet is mapped to the recording window as follows:

Corresponding Experiment Settings:

Experiment > right click > Experiment settings > Recording

Option (1): Check option 'Maximize recording window'.

The recording window expands during recording and the tablet is mapped proportionally to this.

Option (2): Check option 'Make recording window real-size' (REAL SIZE TARGETS).

In experiments with visual feedback, it is crucial that the size of the targets on the computer display and the tablet are real-size. Additionally, the recording on the tablet when visually fed back should reflect the actual sizes of the strokes.

Test:

For Option (1)


Printing Elements/Stimuli Real Size

To print a stimulus in real-size on paper (i.e., the same size as on the digitizer), so that subjects can perform writing tasks with direct visual feedback instead of displaced visual feedback via the display, MovAlyzeR needs to know the actual sizes of the x and y axes produced by the particular printer.
