[sci.electronics] Data Glove

I am doing a project using the Nintendo Power glove to control
a robot arm.  I was wondering if anyone has specs on this sucker
or knows where I should look.  This is my first post so I am not
sure about the distribution.  Thanks.

I asked the same question of the group yesterday, and a number of
people pointed that the July, 1990, issue of Byte had a review of the
power glove.  Here's a brief summary of the article, which is entitled
"Reach Out and Touch Your Data".

	The article reviews three gloves, the VPL DataGlove, the
Dextrous Hand Master, and the Power Glove.  The first two sell for
around $8000-$15000, depending on the options chosen; the power glove
sells for less than $100 (one poster found it for $70, with a $10
rebate certificate included).  The first two are professional quality,
have standard or quasi-standard interfaces, return high-accuracy data,
and are, in general, what you would choose for professional work; the
Power Glove, built with kids in mind, is, in the reviewer's opinion
the most robust of the three.

	The power glove incorporates two types of sensors, strain
gages and ultrasonic rangers.  There is one strain gage per finger
(not per finger joint) to measure finger flex.  The ultrasonic ranging
system consists of a pulse transmitter on the glove and a system of
ultrasonic detectors that mount on the TV.  A microprocessor converts
the raw data to provide information on flex of each finger, position
of the hand in front of the TV, and orientation of the hand with
respect to pitch and roll.

	If I understood things correctly, that information is then
converted to standard Nintendo game inputs.  I'm not sure whether the
intermediate information (amount of finger flex, hand orientation,
etc.) is thrown away, though that was the impression I got.

	The article also includes information on interfacing the Power
Glove to a PC.  This includes the necessary modifications to the
Nintendo connenctors, where to tap off 5-volt power for free, etc.  He
also includes a brief assembly language demo program.

	Want to know more?  Read the article!  If, in your
explorations, you discover anything the article failed to mention,
please let me know.

	Thanks to all the people who responded!  Hope this summary
helps.
