This stuff is awesome! Both of us never did an exercise like this before and my love for drawing on white boards only got better. As we understand that readers cannot read our scribbling on the board we made an electronic version of our mind map.
We sure did think of a variety of things, but a Bing search for similar devices revealed a few interesting pieces of tech. There was a company, which tried to make a device that could electronically simulate smell! They shut down as there was no market for those devices. One of the papers we studies researched on the feasibility of an inflatable mouse that can perform gestures using pressure sensors!
The air hockey analogy can bring up a whole new gripping pattern. Even gestures could be easy with a grip like that and who wouldn’t love an elevated mouse 🙂
