Every once in a while, I’ll try my luck with landscape sketches in gouache. I like gouache because it allows painting opaquely, and together with my small watercolor kit, it’s still convenient enough to carry around.
Pocket Observatory at Make Munich! Slipped in at the very last minute, and probably had the tiniest desk in the hall. But the response was great, I am still totally overwhelmed by the positive response and all the enthusiasm. A huge THANK YOU to everyone who came over to check out the app on Gear VR! Nice people, great conversations, useful feedback, and even more ideas for future development. After two days working the desk non-stop (together with my wonderful GF) I feel a little spent but very inspired 🙂
On 3/16, Pocket Observatory has been released to the Oculus App Store for Gear VR! It has taken a lot longer than expected, but in the end, the additional iterations and feedback have improved the product tremendously. Of course, this is only version 1 – there are tons of additions on my list already, and I am open to suggestions 🙂
Here’s a link to the product page in the store.
The past few weeks I’ve been working away on a really exciting feature for the upcoming Gear VR version of Pocket Observatory: You will be able to invite a friend (on the Oculus platform) and start a voice chat beneath the stars! GPS coordinates are exchanged between the app instances, so players can visit each other’s GPS locations. This is currently under review, and will hopefully be up in a few weeks in the Oculus Store.
To my knowledge, this is the very first social VR astronomy app ever! I’ve been thinking about this for quite a while during initial development, but didn’t realize how easy it would be to integrate using the Oculus platform SDK. Mind you, setting up peer-to-peer networking can still be nerve-wrecking, given the unreliable nature of network communication, but still… managed to pull this off in just a few weeks. Happy!
Check out the updated page at https://pocketobservatory.com for the details. Here’s a screenshot of the chat UI: (thinking about avatars and a shared space experience, too, but that’s for later.)
Now that I’ve gained some experience with Virtual Reality and my astronomy app, I’m thinking educational software for VR could be a worthwhile field for future projects. So I’ve started tossing ideas about, one of which involves playing with molecules in a VR environment.
Just finished and submitted the iPhone / Google Cardboard version of Pocket Observatory! It really paid off to use Unity – porting from Android with the Oculus SDK to iPhone with GoogleVR turned out to be really easy.
Here are the quirks I encountered, might be useful to know if you’re embarking on a similar project:
- In Gear VR, system messages (e.g., asking for permissions) are displayed properly and can be confirmed while you’re in VR. On the iPhone, a standard system dialog pops up. To deal with location service permissions, I trigger the message from within a special startup scene, before entering VR mode in the main scene.
- Texture compression support has to be adjusted with the platform. On the iPhone, compression defaults to PVRTC, which requires square textures. The Unity importer stretches non-square textures to make them compressible with PVRTC. This results in awful artifacts, so I had to go over the compressions options for all of my (non-square) textures.
- Make sure the text for camera use permission is set in the iOS player settings – in GoogleVR, there is a UI button to allow the user to switch viewers. This will activate the phone’s camera in order to scan the QR code on the viewer. Not setting the text will result in an app crash.
- Unfortunately, the Cardboard app doesn’t run in the simulator – there is no suitable architecture of the gvr library, so the app crashes at startup. I guess it would be possible to build the library from source, but haven’t tried that yet.

Haven’t posted as many updates here as planned, because I was terribly busy finishing implementation. But I have started
- an Instagram channel (@pocketobservatory)
- and a Tumblr blog, just to share the IG posts to the web: pocketobservatory.tumblr.com
Now it’s all about finishing materials for submission to the Oculus store, and setting up a landing page, etc. Coming soon!
Yes, I have decided on a name for my upcoming Gear VR astronomy app: Tadaa – Pocket Observatory! Seems it is getting to a decent stage… it’s hard to stop adding features when new ideas pop up every five minutes, but this all has to wait for future releases. Now, it’s all about polishing and optimizing!
I found a really, really helpful guide to optimizing Gear VR apps on the Oculus developer blog: https://developer3.oculus.com/blog/squeezing-performance-out-of-your-unity-gear-vr-game/. This certainly saved me a few headaches.
Here’s a very first video impression of the app: https://youtu.be/G4tHM2v0NyY I was actually wondering how I could do a video such as this, but it turned out to be super easy: Integrate the platform menu provided with the OVR toolkit, and the function is available in the platform menu by pressing the back button 🙂
Slowly, but steadily, it’s coming together. Since my upcoming stargazing app is also featuring a nice landscape and daylight, I am currently spending quite some time adjusting lighting and the complexity of the scene. After all, this has to run with a steady 60 fps on the Galaxy S6 with the Gear VR headset.
Mind you, the scene is not complex by today’s standards, but hey, this is still a phone!
