Advanced Calibration – Drag mode

Advanced Calibration – Drag mode

Overview


DRAG MODE Calibration is for sensors with custom shapes and sizes, or for when the desired active area is smaller than the full-size sensor.
The DISPLAX Connect interface will be displayed on the entire screen, you must define the desired active area.
The below examples demonstrate the calibration of (1) a rectangular section to be the active, touch-responsive area within a sensor; and (2) a circular touch sensor such as the SKIN ROUND.
Other shapes are available for custom DISPLAX SKIN Sensors, such as triangular and eliptical, and the calibration process will follow the same steps, with the relevant shape selected.

To start the calibration process of custom size sensors, or specific areas within sensors, see the following examples.

Instructions

    1. Rectangle

  1. Select the CALIBRATION tab
  2. Select the relevant screen, if using more than one
  3. Select the Drag Mode
  4. Select Rectangle
  5. Click on CALIBRATE


  1. The screen will turn black and a message will be displayed "Please select the area"


  1. To select the area, left-click the mouse at any corner of the desired active area, then move the cursor on the diagonal towards the opposite corner
  2. Upon selecting the area, you will notice a transition from a red to a green shape. Red means that the area is too small for calibration


  1. When the area selected is not large enough, a message will be displayed: "The selected area is invalid, please select again"
  2. When the selected area is large enough to be calibrated, the selection turns green


  1. Upon releasing the left mouse button, you will have the option to move, rotate, and/or adjust the size of the selected area
  2. Once complete, press the Space bar to continue, or the R key to restart the process



  1. Upon pressing the Space bar, four calibration points and an instruction will be displayed,  "To start calibration, touch on the target until it disappears. Repeat the process for the remaining points."


2. Circle

  1. Select the CALIBRATION tab
  2. Select the relevant screen, if using more than one
  3. Select the Drag Mode
  4. Select Circle
  5. Click on CALIBRATE

  1. The screen will turn black and a message will be displayed "Please select the area"


  1. To select the area, left-click the mouse to start drawing a circular shape across the display
  2. Upon selecting the area, you will notice a transition from a red to a green shape. Red means that the area is too small for calibration
  3. When the area selected is not large enough, a message will be displayed: "The selected area is invalid, please select again"

  1. When the selected area is large enough to be calibrated, the selection turns green


  1. Upon releasing the left mouse button, you will have the option to move, rotate, and/or adjust the size of the selected area
Ensure to leave a black border between the edge of the display and the circle perimeter, +/- 2cm, so that all 4 targets are entirely visible inside the display. This does not mean touch will not work outside the selected area, it is purely for instructing the OS of the geometric calibration of the touch sensor.
  1. Once complete, press the Space bar to continue, or the R key to restart the process
  2. Upon pressing the Space bar, four calibration points and an instruction will be displayed,  "To start calibration, touch on the target until it disappears. Repeat the process for the remaining points."

3. Ellipse

  1. Select the CALIBRATION tab
  2. Select the relevant screen, if using more than one
  3. Select Drag Mode
  4. Select Ellipse
  5. Click on CALIBRATE


  1. The screen will turn black and a message will be displayed "Please select the area"


  1. To select the area, left-click the mouse to start drawing an elliptical / oval shape across the display
  2. Upon selecting the area, you will notice a transition from a red to a green shape. Red means that the area is too small for calibration
  3. When the area selected is not large enough, a message will be displayed: "The selected area is invalid, please select again"

  1. When the selected area is large enough to be calibrated, the selection turns green

  1. Upon releasing the left mouse button, you will have the option to move, rotate, and/or adjust the size of the selected area. 
If the sensor is covering the entire display, ensure to leave a black border between the edge of the display and the ellipse perimeter, +/- 2cm, so that all 4 targets are entirely visible inside the display. This does not mean touch will not work outside the selected area, it is purely for instructing the OS of the geometric calibration of the touch sensor.
  1. Once complete, press the Space bar to continue, or the R key to restart the process
  2. Upon pressing the Space bar, four calibration points and an instruction will be displayed,  "To start calibration, touch on the target until it disappears. Repeat the process for the remaining points."


4. Triangle

  1. Select the CALIBRATION tab
  2. Select the relevant screen, if using more than one
  3. Select Drag Mode
  4. Select Triangle
  5. Click on CALIBRATE


  1. The screen will turn black and a message will be displayed "Please select the area"

  1. To select the area, left-click the mouse to start drawing a triangular shape across the display
  2. Upon selecting the area, you will notice a transition from a red to a green shape (red means that the area is too small for calibration) and the instruction:
    1. "Please draw triangle"
    2. "Mouse movement will follow hypotenuse of clockwise triangle."
  3. When the area selected is not large enough, a message will be displayed: "The selected area is invalid, please select again"


  1. When the selected area is large enough to be calibrated, the selection turns green

  1. Upon releasing the left mouse button, you will have the option to move, rotate, and/or adjust the size and shape of the selected area

If the sensor is covering the entire display, ensure to leave a black border between the edge of the display and the triangle perimeter, +/- 2cm, so that all 4 targets are entirely visible inside the display. This does not mean touch will not work outside the selected area, it is purely for instructing the OS of the geometric calibration of the touch sensor.
  1. Once complete, press the Space bar to continue, or the R key to restart the process
  2. Upon pressing the Space bar, three calibration points and an instruction will be displayed,  "To start calibration, touch on the target until it disappears. Repeat the process for the remaining points."

Conclusion Notes


Upon touching all targets and completing the process, a message will be displayed: "Geometric calibration succeeded.", and you will return to the DISPLAX Connect interface.
 When selecting the calibration area, an error message may be displayed, "The selected area is invalid, please select again." The selection is too small, in which case a red shape is displayed. Increase the area size until the shape turns green.
