My Touch arrived. Installation was at first a snag; plugging in the second camera started giving me blue screens due to weirdness with a USB driver. Switching it to a separate set of USB inputs took care of that, though. Actual setup pretty straightforward. I was wondering why there was no indication on how to get started pairing the controllers and was having to turn to Google, but Oculus Home noticed the second camera and led through the process of pairing and such. Also pretty friendly about telling how you should adjust the angles of your cameras. I had them pointing much too much towards me in the center.
My limited area of use is already a problem, though. In the future when using this I'll move away the tables I have my keyboard/mouse/etc. on as much as possible, but when doing the intro demo I was running into them all the time. Try to pick up one of the disks from the robot, smack into a table. Having the Guardian thing on was interesting for a bit, in as much as now it was possible to see in game when I'd be knocking on the shelving immediately to my left. Since I'm in a pretty small area, though, being surrounded by a blue grid a very short distance away was pretty annoying so I turned it off.
Picking things up feels a bit ham-handed; since the grip acts as three of your fingers, it feels kind of like wearing mittens, though these mittens at least allow the index finger to be separate. Probably the most fun things I've yet run into are where I had to use two hands together in a natural way. Like holding a firework in one hand, shaking open a lighter with the other, then lighting the fuse. Or holding a slingshot in one hand, and using the other hand to pull back and shoot it.
One of the earliest Riff apps, Ocean Rift, has new Touch controls. After trying some of the other demos the lack of matching finger positioning stuck out. With gamepad you'd use the analog stick to change the direction of swimming, with a button each for going up and going down. Touch replaces that with two alternate methods. You can either use the triggers in a crude approximation of swimming that's more pushing or pulling yourself around the ocean, or you can aim in a direction and use the grip to activate hand propellers which will move you in that direction. No new creature interactions.
