hololens

问题 I'm trying to create my own Unity project with speech recognition in Hololens. I copy pasted the instructions from tutorial. Literally copy pasted the SpeechManager.cs file and SphereCommands.cs file to my project but it won't budge. I tried putting some sounds in: KeywordRecognizer_OnPhraseRecognized to see if I get there (even before invoking anything), but I don't. I start the keywordRecognizer.Start() (also added sounds to make sure I was there) but I have no idea if it's working

问题 I need to change the expanding direction of the VerticalLayoutGroup. With the default behavior the group will expand downstairs. What i want is, that the group will expand upstairs. The expected behavior is described in this Video. (Link to the answer on stackoverflow https://stackoverflow.com/a/43192904/11236801) The solution on the link is, to rotate the LayoutGroup about 180°.

We are actually trying to update the height of the menu to the camera's frustum height, so that the menu always takes up exactly the vertical height of the camera's view. Is this the way towards a solution? What are we doing wrong that the new size does not match the cam' frustum height? We have

问题 I have a websocket server running on a pc connected to the pc through a switch. When I make a websocket client in the HoloLens with the IP of the server it doesn't connect. How come? I cannot ping the HoloLens emulator from the pc with the server but I can ping the pc running the emulator. 回答1: By default all interactions with the emulator are done through a 169.254.xxx.xxx address.

问题 I have planned to start building an application for the Hololens in a month from now. So right now, I am just in the preliminary design and feasibility check. (For the record I have built simple applications for the Hololens using Unity and also have used the camera for some image recognition) My main concern is methods of inputing data to my application. In a normal application you have GUI widgets such as spinners or sliders, if you want to enter a numberic number. How can I input numeric
