3D Buttons and Sliders

Here is a quick video explanation of the HitArea and DragArea render engines.

The engines can track when a pointer enters and leaves them, and the DragArea engine also reports back the pointer's relative position--handy for sliders, etc.

More Fake 3D

Here's more work on faking three dimensions on a flat plane.

Again, this only works from the perspective of the ball, so one person needs to hold it fairly near their point of view to get the effect. And, from the brief demo we did at the workshop, sometimes people need a few minutes to adjust to the effect before they feel like they're navigating space.

At this point, it seems like more of a fun demo or a parlor trick. One really good suggestion we got recently, though, was that we could give participants a button, say on a Wiimore, that would allow them to assume the first person perspective if more than one person is navigating the space. That might help share the experience a bit better.

Faking 3D on a Flat Plane

We were experimenting with different ideas for how to represent the third dimension you have access to with the SMALLab installation. This is a trial using a camera viewpoint that tracks the position of the ball as you move through a space with it. It fools you into thinking that a 3d world is changing at your feet.

It's not a perfect solution. It only works for one person, and there are limits to how high you can pretend the Z-axis goes. Still, it's an interesting way of looking at the problem, and it might open more doors later on.
