Many console dance mats have large arrows that can be pressed with the feet, perhaps from a sitting position. How about repurposing one of these to provide mouse input? Using something like Joy2Key, and Keyboard mouse controls, such a device could be mapped to mouse input.

Why would developers make an app that's restricted by an interface that would work on a phone and not a desktop? Essentially they would still have to write two different apps, or at least two different interfaces. Metro didn't seem to take off on the desktop so I don't think universal apps with similar interfaces will either, desktop users don't want them and writing apps that essentially only benefit a small userbase is not effective use of resources.

I have a relative that could use something like this, I hope it becomes affordable and readable for them soon.

I'm sure there are good reasons to datamine and bad reasons as well. Some goals yield benefits to many while others are more selfish. The question is if there can be more good done or more bad, and if the benefits outweigh the pitfalls. What are we wiling to sacrifice? Are our desires important enough to risk the pitfalls? Do we think we can account for the pitfalls and protect ourselves against them, or are we just being arrogant and blindsiding ourselves?

Why am I asking you?

Same here, without it stuff just looks choppy and pans are jittery.

Just spent a good deal of time looking for solutions for Linux and I can't seem to find one, that's too bad. SVP is windows-only :(

A lot of people get caught up using these services and wind up judging the people they follow whether they troll them or not, even if snarky thoughts aren't expressed, they're still made, just from scrutinizing so much on such a scale. Just don't go on there every day and take it easy, it'll be better for your mind as well as your exposure to vitriol.

There won't be much to do on/with Windows for the Pi 2, the only thing people will be porting to it is the same open source software that's on Linux for the Pi, buy why take all the work to do that and accomplish basically the same thing that's already possible with Linux? Practice for developers I guess, but I don't see what new opportunities having Windows on the Pi will do, it's not like that will bring along the Windows software ecosysytem. It will be the same ecosystem we already have on Linux, except piece by piece and not everything will be there for a while. It will be easier and faster to get up and running with Linux on the Pi. Will Windows even be able to catch up in this niche that's already so well served?
