How to access trackpad or DPAD input controls in unity application?

In my project I made an unity android application support for ODG glasses R7. There are two modes for taking input controls in ODG glasses , one is cursor mode and other is selector mode. In selector mode there is a trackpad or DPAD for input controls.

Swiping the Track Pad up, down, left, or right function in the same manner as standard 4-way arrow keys on a keyboard, allowing the user to select items, buttons , navigate through the interface, or scroll. So the thing is that when I run my application on ODG glasses he should not get access to selector mode and not able to access the left, right, up and down swipe events!!

Can anyone help me out how to access the trackpad in ODG for unity application!!
