Another target I’d like to accomplish is to provide an api for generating custom parameterised EyeTracktive pupil tracking headsets. OpenSCAD can theoretically produce .stl or .png images via the cmd line, but it requires a lot of cruft to get this to work (an XServer or xvfb) – so wouldn’t it be nice if there…

Unity style/VrActivityTheme not found in AndroidManifest.xml bug?!?
If you run into the obscure and painful problem that Unity tells you the “style/VrActivityTheme not found in AndroidManifest.xml” then fear not. You do not need to spent half a day trying to track down the problem. At some point you probably (temporarily) added Google’s DayDream as a supported VR Device in the Unity Player…
Why it is tricky to use a VR Reticle as an input mechanism
As long as we don’t know where each individual eye is looking, a reticle may appear to be in two places at once, or one view of the reticle may be suppressed. In some cases this may be acceptable, when the user has the option to close one eye of their choice and position the…
Tales From the Trenches – Upgrading Unity 2018 to 2019. Where’d the TrackedPoseDriver go?!?
I decided it was time to move onto the 2019 version of Unity. I tried upgrading the project automatically and was immediately met with a compile error : “The type or namespace name ‘SpatialTracking’ does not exist in the namespace ‘UnityEngine’ (are you missing an assembly reference?)”. This in turn meant that the TrackedPoseDriver wasn’t…
EyeSkills Newsletter – Design. Code. Refactor. Rinse. Repeat. 09.04.2019
Thanks! Thank you to Gregory Taschuk for his 20EUR donation to the EyeSkills PayPal Pool! The pool has already paid for a simple 3D printer to help prototype parts for the eyetracktive.org headset. If we can get another 150 EUR in the pool in the next six days (to bring it to 500 EUR) I would…
EyeSkills Newsletter – Prototyping Madness 20.03.2019
Hiya! So much has happened in the last two weeks that I barely know where to begin…. but I must begin with a wave of gratitude. First of all, I would like to express my heartfelt gratitude to Holger Hahn and Andreas Freund, who have both donated to the project (https://www.paypal.com/pools/c/8byPUuuQ1D). I’m utterly blown away.…
Struggling with a serialization error?!?
For some reason, I can run my current Unity spike on the laptop, but not on the phone. I finally managed to find some indication of what might be going wrong by attaching the debug process to the phone (having built a development version with script debugging) and restarting the app. Conclusion : Assemblies break…
The second Hackademy weekend.
The energy, the passion, the determination of this team never ceases to amaze me. More amazing progress. Let’s start talking about hardware: My focus was on continuing the work to produce a new central component for Google Cardboard (v2) capable of supporting eye tracking. This is an intermediate design – laser cut from card, with…
A quick note on Unit Testing in Unity
The Unity/VR learning curve hadn’t left me space to tackle unit testing until now. Well, it had, but my initial encounter was so bad that I decided to leave it until I had a little more time to look again. Well, at the moment I’m building out the basic structures for handling a more fluid…
