application software reduce the data

intensity of) defined areas of 2D data

visible to MX Cameras in a Vicon MX

system. By default, .vtt files are saved to

the active Session folder of the open

database. Similar functionality is provided

by the .xcp file in Nexus. Also see

MX Camera, Threshold grid, and .xcp file.

W

Walking speed A temporal parameter

used in gait analysis for the speed of the

current foot based on stride time and

stride length. Also see Gait analysis,

Stride length, and Stride time.

Wand See Calibration wand.

WEEE compliant Vicon hardware that

complies with Directive 2202/96/EC

concerning the disposal of Waste

Electrical and Electronic Equipment

(WEEE). This European Commission

Directive provides for the disposal of

certain equipment that may not be

treated as household waste. Also see

RoHS compliant.

Workspace The area in the view pane

in which data can be viewed and

manipulated. The type of workspace

displayed depends on the type of view

pane selected. Also see View pane and

3D Workspace.

Workspace axes A visual

representation in some Vicon application

software of the X, Y, and Z axes in the

global coordinate system. These axes are

specified as part of the system calibration

process. They can be visualized in the

3D Workspace. Also see 3D Workspace,

Global coordinate system, and System

calibration.

Workstation Vicon application software

for data acquisition and processing of

optical motion capture. It contains

functionality to set up, calibrate, acquire,

verify, edit, and process motion data from

Vicon systems as well as analog data

from third-party devices such as EMG and

force plates. It also controls capture of

digital reference video and real-time data

streaming.

Workstation is the core motion capture

and processing software for life sciences

applications. A range of plug-in software

is available to extend Workstation

functionality. Also see Plug-in, PECS,

Plug-in Modeler, and SIMM export plug-

in.

X

.x1d file A binary file with extension

.x1d, which contains unprocessed data

from analog data capture in Vicon Nexus.

By default, .x1d files are saved to the

active Session folder of the open

database. Similar functionality is provided

by the .vad file in earlier Vicon application

software. Also see Nexus and .vad file.

.x2d file An XML file with extension

.x2d, which contains 2D camera data

previously captured in Vicon MX systems.

This can be a mixture of unprocessed

grayscale blobs, calculated centroids, and

coordinates data. By default, .x2d files

are saved to the active Session folder of

the open database. Also see Centroid,

Coordinates data, Grayscale blob, and

Vicon MX.

.xcp file An XML file with extension

.xcp, which contains the calibration

parameters and threshold data specified

for Vicon cameras and supported third-

party digital video cameras in Vicon

Nexus. This file is created during the

MX Camera and DV camera calibration

processes and used when data from

these cameras is processed. A copy of the

.xcp file is saved to the active Session

folder of the open database. Similar

functionality is provided by the .cp and
