Daniel here again! This time around, I’ll talk a bit about how we handled integrating the UI Widgets into the data model for Planetarium, and what this means for you.

The first iteration of Widgets we released to developers was cut almost directly from a set of internal interaction design experiments. They’re useful for quickly setting up a virtual reality interface, but they’re missing some pieces to make them useable in a robust production application. When we sat down to build Planetarium, the need for an explicit event messaging and data-binding layer became obvious.
