Hello!

Comes time to perform a backup of some of the sutff I’ve learned about Hololens and HoloToolkit. This one is related to a basic feature in any app

Present a menu and select an item. In Hololens using AirTap

The idea is to view a board with different options, and the option selected will be displayed in a top 3D text

In previous posts I have already commented on how to create a Unity3D project and how to import the HoloToolkit. From here, the following steps would be

• Delete default assets: Main camera & Directional light
• Save Scene
• Adjust UWP projects settings to be Hololens capable
  • Project Settings / Player
  • Project Settings / Quality
  • File / Build Settings
• Import HoloToolkit
• Add Assets
  • Main Camera
  • Spatial Mapping
  • Cursor With Feedback
• Create Empty and Rename > Managers
  • Add Components
    • Gaze Managers
    • Gaze Stabilizer
    • Gesture Managers
    • Hands Manager
  • Add Assets
• Create Empty and Rename > HoloCollection
  • Add Assets
    • Add Cube, add SAD image to cube
    • Add Cube, add HAPPY image to cube
    • Add Sphere, add SAD image to sphere
    • Add Sphere, add HAPPY image to sphere
    • Add 3D Text, name “TextResult”

The components hierarchy should be similar to the following

And now is the moment to create some interaction feature. So a single script called “EmojiSelector” will do the magic

In this script I would add a couple of lines in the OnSelect operation. This operation is is called from the GestureManager when performing an AirTap on a selected item. The Script obtains the item selected from the GazeManager and if it is valid, displays the name in the Text called “ResultText” 3D.
