Re:How hobbyist friendly is this field?Lil late, I used to work in the neurolab in 1998 and spent some time on the software for the BioMuse which was the first generation of the hardware behind this stuff. They have much more advanced technology out, but biocontrol is a good starting point. I haven't been out to the lab since I left so I'm not sure at all what they are using now.
Good luck with it.

Re:no chording?That doesn't really work, just in case you were wondering. I've done some interface extension research, and all the results point that tendon tension is too crude. We actually did a lot of studying on this, and the annoy thing about it is the tendons will be a different tension if the wrists are turned in a different position.
Another problem is that some people (for instance, myself) have enough skin and muscle over the tendons that you dont really get any signal from them whatsoever.
And the final problem that comes in, calibration is a bitch. You calibrate for one person and they use it, then another person and another. After dealing with calibration matrices for each and every person, with all of the possible rotation permutations it just becomes overly intensive to monitor each option.
A really promising approach is using dry electrodes to monitor EMG signals, these can be in the form of a tight bracelet and arm band. BioControl has some really cool stuff in this world. Such as a quarter-size diode that sits on your forehead and you move the mouse with your eye movement, it really actually does work well too.

Re:Oh, but if only...
I did some work using EMG signals to operate as a system controller. It gets to the point after calibration (which takes many many minutes) that you can control the signals with slight twitches instead of full motion. I think that haptics/gloves are more or less stupid unless it's a system that is designed to interpret natural movement and not a programmed controlling (Move your hand 4" up, then 2" right then 2" left and wiggle your thumb to right click). With EMG reads you can twitch.. slight muscle movements that are barely perceptible that become like second nature. That was the goal, my term working on this we never got a "functional" interface.. the mouse just got real jittery but it was a starting point.
If you are interested in fully interactive controls look at that technology - biocontrol has some cool toys to play with too -
BioControl Systems
BioControl Systems is one company I know of. I saw and played with their stuff back in '95 at a VR conference (MecklerMedia VRWorld '95)
BioMuse is one I played with. -

Hand in hand with tablets... (Off Topic)
eGlasses!
So PalmPilot made a concession with handwriting recognition and create Grafiti, or however you spell it, to speed up usage and adoption of the technology.
Imagine something similar, but to replace or supplement styluses! These glasse are either clip ons for regular glasses or a real pai, or if nothing else, a monocle, or something you strap on next to your eyes...
These things will register eye movement.
No more scrolling manually, no more clicks to page flip, to select text, to select links, etc.
Looking at a margin causes scrolling in that direction. If you squint too much, text gets enlarged. If you stare at a word, a popup with its definition and context can appear. Stare at a link, and you are transported there. Look at a button, and it's clicked. Look at an index, and get sent to the correct page. Page scrolling speed adjusts to your reading rate.
Wouldn't that be just cool?
I think it's very possible, see stuff on BioMuse to see more...
