I'm Peter and Nice to meet you!

Hi Peter,

Likewise, it's nice to meet you!

My friend's company is working on a miniature camera (2-3mm across) that shows dentists exactly what's going on inside the tooth as a dentist performs a root canal. From what I understand, such procedures are very haphazard right now, and dentists often drill much more than they have to.

I visited a research lab in Colorado last month and got to try out a surgical pen device. It was really cool. Unfortunately, I can't seem to find it on Google, but I can email the guys and find out what it's called, if you're interested. The tip of the pen was connected to a mechanical arm that applied resistance to the pen's movement based on the pen's location. They had a demo setup where you can poke a virtual cow. When the pen is far away from the virtual cow, there's no resistance in movement, but when the pen gets close to the cow the pen's movement is resisted in such a way that makes it feels like you're poking a virtual cow. I'm not a cow-poking expert, but based on my experience poking steaks, I can say it was pretty realistic. Doing something with that device connected to some 3D visual input devices would make an interesting MRSD project.
