VRTK_HeadsetControllerAware

Overview

The purpose of Headset Controller Aware is to allow the headset to know if something is blocking the path between the headset and controllers and to know if the headset is looking at a controller.

Inspector Parameters

• Track Left Controller: If this is checked then the left controller will be checked if items obscure it's path from the headset.
• Track Right Controller: If this is checked then the right controller will be checked if items obscure it's path from the headset.
• Controller Glance Radius: The radius of the accepted distance from the controller origin point to determine if the controller is being looked at.
• Custom Right Controller Origin: A custom transform to provide the world space position of the right controller.
• Custom Left Controller Origin: A custom transform to provide the world space position of the left controller.

Class Events

• ControllerObscured - Emitted when the controller is obscured by another object.
• ControllerUnobscured - Emitted when the controller is no longer obscured by an object.
• ControllerGlanceEnter - Emitted when the controller is seen by the headset view.
• ControllerGlanceExit - Emitted when the controller is no longer seen by the headset view.
