Hololens developing: How to use Holotoolkit and Understanding HoloToolkit (4), Show Gaze info on the Text

In last post, we put a text message on top-left corner of screen, now we are going to add a c# script onto the text, letting it show what the user is looking at

First add a tag to the cube, name is as "cool cube"

Create a "Scripts" folder and add a c# script ShowObjectName.cs

Edit the script in Visual Studio,

Save and assign this code to the Text

play the scene in Unity, you can see the text is now showing what the cursor is aiming at
