HoloLens Blueprints

Adding the Box Collider

Once the GazeManager class and Cursor is in place, the next step is to identify the gaze able objects. As part of the requirement for this project, we discussed highlighting the Lenses and Speaker. To gaze at an object, the very first thing you need to do is add a Box Collider to the object. The Box Collider is one of the basic collision primitives in Unity. The ray can happen on the basis of the Collision on the object that you are looking at.

Our objective is to gaze on the Lenses and left-side speaker. So, our first job would be identifying them from Object Hierarchy and then adding Box Collider components.

1. Expand the HoloLens Game Object from Object Hierarchy.
2. Select lens_geo.
3. Navigate to Inspector Window |
