There's been a couple of suggestions to finger drums (see
link). I've had this idea for awhile but with spin on it.
Most ideas work on a buttons, so that when you tap your
fingers it closes a switch and works very much like a
traditional keyboard albeit in a glove. I suggest a similar
but the sensors mechanism would be accelerometers on each finger.
The advantages would be that authentic finger-on-counter
feel that all the old school finger drums strive for. If you
got a 2 axis accelerometer you could also detect your
fingers moving towards and away from your fist, for
actions such as playing different sounds in a grid layed out
on a table.
Alternatively I suggest a similar system but using Piezoelectric sensors that hear the vibrations and infer
volume etc from that. that way when you set up your book
as a bass drum and plate as a hi-hat the software can
automatically interpret these as different drums.

|[+] for the variant in para. 4. Basing the sound on
the actual mechanical ringing of the book, plate,
etc. is nifty. You'd wind up strolling around
tapping various objects to hear what they
sounded like. <link>
|Problem is, the pickup in the glove would tend to
lose mechanical contact with the object after the
initial transient, and before it had finished
ringing. You might need a sort of "dead" tapping
action, in which your finger tip, instead of striking
and rebounding, struck and remained in contact
a few 10s of milliseconds.
|Also, plenty of empirical DSP, but that's no
disadvantage: people would enjoy playing with
|I think you could get around the short contact, by
picking out the fundamental frequency which could
be calculated in just a few short wavelengths. I'm an
avid finger drummer and will always make the BD
sound with my thumb, and hi hats by clicking
fingernails. I think a piezoelectric sensor could
differentiate pretty fast between those waveforms.
