When I wrote “Touchability,” it had already been a while since a buddy had shown me a haptic mouse he was working on. For example, you could feel an actual bump when the mouse enters and leaves an object (a real version of what developers sometimes call rollover). Force feedback was such an obviously good thing that I didn’t even mention then the cool stuff that’s now happening in this area.
As much as I think physical touchability is good, I want to be clear that I want to make Croquet applications be emotionally touchable, too. I want to capture what it is that makes things seem (be?) real. Even without physical force feedback, it should still be fun to fondle stuff because of active visual and aural responses and good 3D design.
To be sure, I’d love to add to the effect with more sensory stimulus. There are huge possibilities, and I hope folks will explore them. This stuff is cool. There’s someone working on stereo display for Croquet. Others working on large screens in public spaces. I don’t doubt that we’ll see Croquet on small or cheap devices. There’s plenty of room for innovation.
