Support touch input for QNX

The Unity QNX Player supports input via touch devices. To enable this, make sure you meet the following prerequisites and operating system configuration requirements.

Prerequisites

• QNX Image has the required touch libraries and utilities installed.
• Touch configuration is set up for touch devices (QNX 7.0 doc / QNX 7.1 doc).
• mtouch (QNX 7.0 doc / QNX 7.1 doc) service is running.

Configure QNX touch scaling

As the QNX Unity player requires the touch coordinates to be in screen coordinates, configure the following setup in the scaling.conf file:

1. Configure the QNX scaling.conf (QNX 7.0/QNX 7.1) file to use screen coordinates. For example, if you have a 1366x768 display, set mode:scale for the display resolution to scaling.conf: 1366x768:mode=scale.
2. Restart the mtouch service.

Verify your setup

If you have installed the events (QNX 7.0/QNX 7.1) utility on the QNX image, you can use it to verify if the touch service is set up correctly. The reported coordinates (pos) should be in the range [(0,0), (DisplayWidth, DisplayHeight)].

If the coordinates are outside the range, check if the scaling mode in scaling.conf is correct and the touch device specific parameters in the mtouch.conf (QNX 7.0/QNX 7.1) file are matching the used device.
