QNX Touch#

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.
