Datagloves
There are a variety of gloves which can be used for capture
of hand motions. Common uses range from capture hand motions to be used
on a virtual character to puppeteering of a characterss facial expression
or humanoid or non-humanoid appendages.
Motion
Capture gloves range in price from roughly $1100 per pair up to approximately
$25,000 per pair. Differentiating factors include the number of joints
sensed. A five-sensor glove measures curl of each finger but cannot
differentiate the degree of movement per knuckle. Basically, the 5 sensor
gloves record the curl of each finger, from open palm to closed fist.
Sixteen sensor glove record each finger joint and add 'adduction' (recording
how close or far apart each finger is). 22 Sensor gloves measure motions
of the palm, including more complex motions of the palms.

supplies Datagloves from Fifth
Dimension Technologies (5DT) and Cybergloves from Immersion
3D.
5DT Data Glove 14 Ultra
Similar features to the 5DT Data Glove 16 but with newly designed sensors. These gloves offer a much better fit than the 5DT Data Glove 16 or 5DT Data Glove 5, for much greater accuracy. Features new wireless circuitry (included) as well. Cost is approximately $12,000 per pair.

5DT
Data Glove 5
Measures finger flexure (1 sensor per finger) and the orientation
(pitch and roll) of the user's hand. It can emulate a mouse as well
as a baseless joystick. The system interfaces with the computer
via a cable to the serial port (RS 232 - platform independent).
It features 8-bit flexure resolution, extreme comfort, low drift
and an open architecture. The 5DT Data Glove 5-W is the wireless
(untethered) version of the 5DT Data Glove 5. |
The wireless
system interfaces with the computer via a radio link (up to 20m distance)
on the serial port (RS 232). Right- and left-handed models are available.
One size fits many (stretch lycra). Features: Affordable quality Extreme
comfort Open architecture Mouse emulation mode Right/Left hand versions
VR program drivers 8-bit flexure resolution One size fits many Built-in
tilt sensor High update rate Bundled software Low drift.
The
5DT Data Glove 16
Currently a 14-sensor data glove that measures finger flexure
(2 sensors per finger) as well as the abduction between fingers.
It is the higher-end version of the 5DT Data Glove 5. Features:
Affordable quality Extreme comfort One size fits many Automatic
calibration - minimum 8-bit flexure resolution Platform independent
- serial port interface (RS 232) Cross-platform drivers Bundled
software High update rate On-board processor Low crosstalk between
fingers Wireless version available (5DT Data Glove 16-W) Quick "hot
release" connection. |
