My Microsoft HoloLens Adventure - Updates on Studying

A couple of weeks ago I made a post on the study materials I planned on leveraging to learn how to program for the Microsoft HoloLens. Well this weekend was the first time I finally started really digging in and I quickly identified that the videos I intended to use may have been a bit off on exactly what I wanted to learn.

In an effort to be open and honest with everyone with my adventure I wanted to share this and point you towards the resources I’ve decided to leverage instead. As I had mentioned in the last post My Microsoft HoloLens Adventure – Preparing Study Resources I had looked over some Basics videos back in March when I first started looking into this, I haven’t really touched those since March as I was getting kind of board with it and it was all stuff I had done when I was in college.

My Microsoft Hololens Adventure - Preparing Study Resources

As I continue my adventure of learning how to program for the HoloLens, the first step is actually learning how to program! I am lucky enough that I took some programming classes while in College and I’ve done a lot of Scripting in Windows PowerShell – this helps me understand programming constructs. I just need to become more well-practices in the area of Object Oriented Programming and understanding the C# Syntax.

Basics:

To do this I actually started digging in a bit back in March covering some of the basics to refresh my memory. One of my favorite resources is the Microsoft Virtual Academy. I haven’t watched much but the first video I started watching was Bob Tabor’s C# Fundamentals for Absolute Beginners. As the subject says this is for absolute beginners so I’ve done a bit of skimming on a lot of the videos, but it gives a good introduction if you haven’t programmed before. I most likely will continue to skim these videos occasionally just to keep my mind fresh since I haven’t written a full blow application before.

Universal Apps:

The next video series I intend to watch is the Developing Universal Windows Apps with C# and XAML. The reason I am wanting to check with video out is my applications I want to have work across all Windows Platforms – this is something I’ve never done so it’ll be a challenge to pick it up. The nice thing about using this as a stepping stone is Universal Apps will not only work on HoloLens but also Windows 8+ Windows PC’s and Windows Phones.

HoloLens Apps:

When developing for the HoloLens there are two different types of app models, let’s explore each one.

2D Apps:

2D HoloLens apps will be the easiest ones to build – at least I think it will be for me. These apps are just like any other Windows Universal App, except the HoloLens will project the 2D App on a wall, or in front of you while using the HoloLens.

To make 2D Apps on the HoloLens I am intending to heavily rely on the Developing Uniersal Windows Apps with C# and XAML that is referenced under Universal Apps section.

In addition to the video the Microsoft Dev Center also has a couple of pages on building 2D Apps.

Building 2D apps Current limitations for apps using APIs from the shell

Holographic Apps:

Holographic Apps are a very new concept – this is what makes the HoloLens a truly magical experience. You will see 3D renderings throughout your house, office, or where ever you are using the HoloLens at.

To start developing for HoloLens you must understand the different ways to interact with the HoloLens. This includes

World coordinates Gaze input Gesture input Voice input Spatial sound Spatial mapping

To get a better understanding of the ways you interact with the HoloLens I suggest taking a look at the Development Overview video from Microsoft.

そろそろWindows10 Phoneも出そうなので、少々調べた小ネタをまとめていきます。

自分用のメモなのでわかりにくいところはごめんなさい。

PCのデスクトップ画面で全画面表示にしたい。

→以下のメソッドを呼び出せばよい。

Windows.UI.ViewManagement.ApplicationView.GetForCurrentView().TryEnterFullScreenMode();

やめたいときはこれを呼ぶ。

Windows.UI.ViewManagement.ApplicationView.GetForCurrentView().ExitFullScreenMode();

現在の画面の状態を取得するのは IsFullScreenプロパティとIsFullScreenModeプロパティを見ればよい。

参考：このあたり

コマンドラインからUWP APPを起動したい

cmd.exeを起動して以下のコマンドを実行する。

start [URI]

例えば、電卓を起動したい場合は

start calculator:

と入力し、実行すると電卓が起動する。

自分のアプリで対応する場合はmanifestに追記し、OnActivatedメソッドをオーバーライドしてあげる。

manifestを選択してマニフェストエディタを起動し、[宣言]のタブを選択

使用可能な宣言でプロトコルを選び追加する。

名前の部分に使いたいURIをコロンなしで設定する。

OnActivetedは引数のイベントで種類を判別してあげる。

URI起動の場合はイベントの種類が ActivationKind.Protocolになっているのでこれで判別してあげるとよい。

Convert Storage File to Byte Array in Universal Windows apps

This async function converts a storage file to a byte array.

https://gist.github.com/wtuts/d1393cf533a081149a24.js

It accepts a StorageFile as argument and returns a byte array for it.

Universal Windows App Project Setup

This tutorial is a part of the series on Building a Universal Windows app using MVVM pattern. In this tutorial we will setup a new project for building a Universal Windows app.

Setting up the Project

In Visual Studio click on New Project and choose Blank App (Universal Windows 8.1) from the existing Templates. If you are unable to find this template in your Installed templates list then head over…
