Hololens

Notes:

All the codes in the Microsoft Hololens Academy are based on the older version of HoloToolkit that used to include classes such as GestureManager and InteractibleManager. These classes are now combined into InputManager. For more info, take a look at this link https://github.com/Microsoft/HoloToolkit-Unity/tree/master/Assets/HoloToolkit/Input
KeywordManager is going to be deprecated. Instead, the use of InputSpeechSource is recommended. Voice recognition is only enabled when the object with this script attached is in focus. We can also use it as global keyword manager by attaching it to InputManager and registering it as global listener.
