Blocks are one of my favourite musical gears from ROLI. Bought this one many years ago. Still use it. Love its modularity and the idea of enhancing a physical object with digital augmentations. Also, it looks beautiful!

A few people asked about my previous prototype: what would happen if you interacted with many boxes? Prototyped how it might look with different motion patterns.

Made a quick haptic feedback prototype for hand-tracking interactions with a voxel. Felt fun and engaging. It's another level of immersiveness (unfortunately, the video is not able to convey this).

One of the most requested features for BoxelXR was the ability to create volumes. Just finished the algorithmic part of the interaction. Will see soon how it works with the hands!

Here are my debugging scripts that I use for my previous demo. They are very useful. It not only helps test math and the correctness of algorithms quickly, but also forces you to decouple key systems of your app from each other to make it work.

Started experimenting with hand-tracking-based interactions for my little voxel editor – BoxelXR. There are many things to tune, but overall it feels good. Though it would require some decent work in sound design to compensate for the lack of haptic feedback.

Wrote an article about math I use to design and develop interactive experiences for AR/VR. I tried to focus on the practical aspects of it and keep it as simple as possible. Hope you will find it helpful!

Balanced Stepper III
Another interaction experiment with a stepper. The main idea behind this piece of UI is that the interaction mechanics favor restoring the balanced default value (zero in this example).

Made a Balanced Stepper. I was exploring a fusion between a slider and a stepper. Came up with an interesting interaction pattern.

Cross Product visualisation for Essential Math for Spatial Computing. I use it this operation a lot when I need to reconstruct some local 3D space base only two available directions.

The dot product has many powerful properties. My favourite one is this: when you multiply a normalised target vector by an arbitrary vector, you get a number, which you can use to scale the target vector and get a projection vector of the arbitrary vector onto the target one!

Tested some of the components of my VolumeUI library in VR. Thought it would be nice to add RGB corners to the backplate as well. So, did it. All components will support some types of RGB animations.
