You have to use IMixedRealityInputHandlerand as a result of this OnInputUp and OnInputDown. This should work also witout any colliders. I'm using this to differentiate between spatial mesh and everything else. Clicking into empty space also triggers OnInputUp and Down.

The simplest thing to do is to use File.WriteAllText method https://docs.microsoft.com/en-us/dotnet/api/system.io.file.writealltext?view=netframework-4.7.2

Obviously there are many ways that could work but it is good to stick to the simplest solution.

There are a number of ways of detecting a hold. For just a generic hold gesture, you can inherit and use the IHoldHandle interface. If you want to get an updated state, you should either use the IManipulationHandler or the INavigationHandler interface.

If you are testing in the editor, use the manipulation handler instead as you can't test the navigation in the editor but it works on the HoloLens.

Your UI Element needs to have a collider, and you need to use the raycast to detect if your ui element is being hit by the raycast. In the hololens the only way that I know of to detect that an element or game object has been hit is using gaze.

Edit: Upon clarification of the problem, you need to make sure that the layer that the raycast is able to hit is only the layer your button is on.

The question asks about detecting if a button is clicked, and the comments bring more understanding of the full problem, but the nature of the question is asked from the perspective of the person asking the questions's experience with other systems not from the understanding of how Hololens and Unity work together, to give the answer you are looking for is not possible because it's the wrong question. Everything in unity is essentially a game object, but they all can sit on different and multiple layers at the same time in the scene, you can see the layers in the top right in unity. The answer to resolve the problem is to specify the layer that the button is on, and that layer is not shared with other game objects which is not default behavior in Unity. When you are doing the raycast, you need to ignore all of the other layers, then you will no longer interact with the background objects behind the button. The link I included tells you how to do that. Once you have done that you would use the airtap event wired to the button like any other game object.

Here is a link on how to work with layers in Unity.

Trying to give you an answer ... hope it helps. I'm a beginner too and I don't have necessary rep for comments, so feel free to ask anything after this =)

As I have understood, you have "Hider" attached to the cube and "ShowAll" attached to the cylinder. Than you need to populate the public list _MyGameObjects by dragging/dropping the cube in the unity editor.

Since the hiding part works, you could use OnInputClicked for the showing part too, since the cylinder you tap on exists (only the cube appears/disappears).

Note: as mentioned in the documentation here, even if you setActive(true) a GameObject with a deactivated parent you will NOT see the object on the scene.

Again, hope it helps =)
Cheers.
