Mouse
The
MovAlyzeR and ScriptAlyzeR systems
are designed to record and analyze with
a mouse as an input device.
If you use your mouse (default
device) as movement recording device, no drivers need
to be installed. Press the left mouse key to produce movements.
Before you begin recording
using the mouse, it is necessary that you calibrate
the device to obtain the correct device resolution
in cm and sampling frequency in Hz and update these
values in the Experiment Settings > Input Device
Settings for each experiment using it.
Refer to MovAlyzeR
Help >
Experiment Settings > Input
Device Settings for the procedure.
Tablet/Digitizer
A
digitizer records pen movements with extremely high accuracy.
Pen movements are more ergonomic than mouse movements.
If you have a Wintab-compliant
digitizer, you can download and install the
manufacturer's Wintab driver. MovAlyzeR uses the
device-independent Wintab tablet driver provided
by your digitizer manufacturer.

National
Instruments DAQPad
Data Aquisition Systems like NI DAQPad, connected to a
force application system through a device interface,
can be used to record force data using the GripAlyzeR.
For
Example, the Gripper device
from Neuroscript (consisting
of an upper grip unit, lower grip unit and a load unit)
can be used as an input device by connecting it through
a device interface and NI DAQPad data
acquisition device.
Refer
to
GripAlyzeR help
for driver installation
Before you
begin recording using the gripper with GripAlyzeR,
it is necessary that you update the resolution in cm
and sampling frequency in Hz in the Experiment
Settings > Input
Device Settings for each experiment using it.
For the gripper device from NeuroScript, the typical
sampling frequency is 256 Hz and the resolution is 1
N.
Also, additional
Input Device Settings need to be updated at Settings > Select
Input Device > DAQPad
Settings before conducting an experiment.

Gripper - Grip Force Measurement
Device
(Used in cojunction
with GripAlyzeR - a MovAlyzeR suite
item)
Bimanual
grip-force coordination can be quantified using a device
measuring the grip forces in left and right hands and
the simultaneous pulling force to separate the upper
and lower force transducers. The task compares to holding
a marker pen in one hand and pulling the cap off with
the other hand. The grip and pulling forces show a highly
proportional increase while increasing the pulling force.
The first prototype is by Alberts et al., 1998. (Click
Here for the abstract).
Gripper Hardware
Setup
The
gripper hardware (consisting of an upper grip unit,
lower grip unit and a load unit) can be used as an input
device by connecting it through a device interface and
National Instruments DAQPad data acquisition device.
The
gripper device is to be used in conjunction with NeuroScript's
GripAlyzeR.
The software communicates with the gripper device through
the NI DAQPad and the device interface to acquire force
sensor data. GripAlyzeR can be used to conduct and record
trials in an experiment, analyze, quantify and plot
the results.
Gripper
Trial Execution |
 |
A
typical gripper task consists of pulling the upper and
lower grip units apart (a magnet holds them together).
While pulling the units apart, apply pressure on the
upper and lower grip sensors using the left and right
hand thumbs, as shown in the above diagrams.
The
gripper consists of two units with each possessing a
force sensor for the thumb. The upper and lower units
are held together with a magnet of a programmable force.
For
more information on the gripper device and testing and
installation, refer to the GripAlyzeR
online help.

the gripper device from NeuroScript, please contact us.
