In the RightBooth settings there is an option to select 'Button' as the user input method. This lets you to provide your users with a USB button to control the RightBooth session.
Asking your users to press a button is often an easier option than asking them to click the mouse or press the spacebar on the keyboard.
RightBooth software installer version 1.0.7 (or later) includes a USB button configuration file: rightbooth.ubn which you will find in your RightBooth installation folder. You can load this file into the USB Button Configuration Utility in order to set your USB button to work correctly with RightBooth.
The configuration utility can be downloaded from www.usbbutton.com.
