3.1 Normal Use Setting
• Set the proportion of the spot (20%~80%): Refers to the sensitivity of touch
reaction. The larger the value is, the lower the sensitivity becomes.
• The brightness coefficient (0~250): Refers to the sensitivity of camera CCD
sensor. The larger the value is, the higher the sensitive becomes.
• Pen touch: Only IR pens will be recognized by the touch screen.
• Finger touch: IR pens and fingers will both be recognized by the touch
screen.
Note: The default values for proportion of the spot and brightness coefficient are
different under pen touch mode and finger touch mode. Users can adjust these
values according to their preferences.
3.2 Auto Calibrate Setting
• Average brightness (0~255): Adjusts the brightness of camera images. Refers
to the sensor's measurement of overall brightness from the "black and white
checkerboard" used during the automatic calibration process. The larger the
value is, the brighter the image will be.
• Light gray (0~255): Adjusts the contrast of camera images. Refers to the
overall contrast of the "black and white checkerboard" used by the calibration
software during the automatic calibration process. The larger the value is, the
greater the contrast between the black area and the white area in the "black
and white checkerboard" will be.
• Recording video: Record the auto calibration progress and save the file. In
the event that auto-calibration fails, users can provide this recorded video to
customer service.
3.3 Other Setting
• Focal length: For PS750 series, the default throw ratio is 0.15:1.
• Rear projector: If your projector is a rear projector, please choose this setting.
(Not for PS750 series)
4.
Auto Mask Clutter (Ctrl + Shift + A): The program will mask all interfering light
automatically. When the single touch (mouse) is functioning abnormally, Auto
Mask Clutter will mask all interfering light.
5.
Manual Mask Area: Click Manual Mask Area when the curser is functioning
abnormally. When the single touch (mouse) is functioning abnormally, Manual
Mask Area will mask interference spots.
6.
Manual Calibration: Execute calibration manually when Automatic Calibration
fails or the cursor location and IR pen/finger position are not aligned.
7.
Automatic Calibration: Execute calibration automatically.
