To be able to understand the descriptions given in this section, it is suggested to first get acquainted with the definitions explained in Parameter Overview.

Use Case

This method of configuring sensor module(s) can be used to get one or multiple touch areas on a larger screen or on a large projected area, further referred to as Screen.

Illustrations                    


Introduction

  1. A Touch Sensor Module can be mounted on four sides of a screen and with the connector to either the right or the left (PCB or silver side down) but we recommend mounting it with the silver side towards the screen, as the touch area is then closer to the screen.

    This will give a total of eight different configurations.

    It is possible to mount a sensor module "on" or "in" the screen. However this will cover/block part of the screen and is therefore not a part of this example.

    1. Top: Sensor module on top of the screen facing down.
    2. Bottom: Sensor module on bottom of the screen facing up.
    3. Right: Sensor module on right side of the screen facing left.
    4. Left: Sensor module on the left side of the screen facing right.

HID Display Size

HID Display Size is the physical size of the screen in tenths of millimeters (1/10 ; 1 mm = 10)

Configurations With Multiple Sensor Modules

If you would like to configure multiple sensors modules for touch on different parts of the screen, please use the settings above for each sensor. If you would like to make this setting with Neonode Workbench, please use the Workspace designated for multiple sensor modules. If you would like to create your own solution, the zForce SDK can be used to implement this.
