Hololens developing: How to use Holotoolkit and Understanding HoloToolkit (3), Add a Text on the screen

Before we introduce Gaze, I want to put a text string on the top-left corner of the screen in order to show any message, for example, when the are looking at the cube, we want to show the user the cube's name from the text message.

Steps:

1)      Add a text to the Hierarchy

=> 

let's talk a little bit about this Canvas, if you click Canvas and check its properties:

you can find the "Render Mode" is set to "Screen Space - Overlay" which means, the Canvas and its children(like Text) will always fit whatever the user see from screen, here it's our hololens view

The "Render Mode" could be set to other values, but we are not interested for now, if you want more detail, please check unity website

Click Text and change the properties to be like this:

change the parameters, make sure you can see the text message on the top-left corner of the screen

done, next chapter we will make a c# script to let the message show what the user is looking at
