Unless you’ve been living under a rock, you should be fascinated (or at least intrigued?) by VR. Check out some articles that gave me inspiration: From product design to virtual reality by Jean-Marc Denis A month designing in VR by Julius Tarng Designing for virtual reality by ustwo After some investigation, turns out it’s actually not that hard to make a VR app, even if you don’t have any 3D or coding experience. Just to give you an example, here is . an app I made using this method Tools you need: A VR headset (I have , but others will work just fine.) Google Cardboard (Download and install the free version) Unity (Download from the section. I’m using Android as an example, but iOS should work as well.) Android SDK SDK Tools Only (Download from Github repo) Cardboard Unity SDK An (Download from Github repo) auto walk script made by Jupp Otto The app we’ll be making is a simple virtual environment tour. You can toggle auto walk using the trigger in your VR headset. Step 1: Create a virtual environment Open Unity. Create a project in the pop up window. No need to modify any settings at this point. I’ll be using this free asset created by , but you can use whatever asset you like. Open the URL, click “Open in Unity”. Unity will load it in the panel. Then click “Download” (Unity doesn’t allow downloading asset directly from the web page). Forest Environment Patryk Zatylny Asset Store After the download is finished, you’ll see a pop up.

Optionally you can add your app icon in the section. Click “Build” in the Build Settings window. During the process, you might get asked to select the root Android SDK folder. Unzip the file you downloaded and select that folder. You might also get asked to update SDK. Just confirm to update. After the build is finished, you can install the app on your Android phone, test it out with you VR headset, or even upload it to Google Play Store! (Sometimes when you rotate your head the camera doesn’t rotate with you. Exiting and reopening the app should fix it. It might have something to do with the SDK version & Android version. Let me know if you find out more details about this bug.) Icon Android SDK You are done! That wasn’t too hard, was it? Rambles Manage your expectations. It’s unlikely that you can build the next or on your first attempt. Start with something small and keep building on top of it. Lower your expectations, under-promise and over-deliver.

There needs to something like “Squarespace for VR” to lower the barrier and get more people involved.
