7.2.12 Scenario
Depending on the type of measurement you will carry out, select the type of scenario that will ensure
the best results, and minimize post-processing. The scenarios available include:
Single Level
This scenario assumes that the subject will be walking on level terrain
Multi Level
This scenario assumes that the subject will be walking on terrain or varying height,
e.g. climbing stairs.
Pelvis Fixed
This scenario assumes that the subject will remain in a seated position, e.g. in a
car. This means that the pelvis will remain at a preset height. Small amount of
motion of the pelvis is accepted.
Pelvis Fixed
Tight
This scenario assumes that the subject will remain in a seated position, e.g. in a
car. This means that the pelvis will remain at a preset height. No motion of the pelvis
is accepted.
Soft Floor
This scenario is used if it can be assumed that the feet will slightly decrease in
height, during the time between the feet contacting the ground and leaving it, e.g.
grass, or soft carpet.
7.2.13 Accept Systems
From this drop-down menu, select the type of hardware connected to MVN Studio. This is set to “Any”
as default, making it easy if only one system is connected. It is also possible to specify MVN Link or
MVN Awinda.
7.2.14 Sync Settings
With MVN Awinda, the dialogue to configure the sync settings is in the MVN System configuration.
To configure the Sync Station which is the method for synchronizing MVN BIOMECH Link with third
party devices, the sync settings are configured via “Insert configuration” “Sync Station”.
It is worth noting that sync with MVN Awinda is tighter than with MVN Link due to the tight control
of the Awinda Station over the MVN Awinda System.
Click the icon: to configure the sync settings.
For detailed information regarding sync settings, refer to section 23.
7.3 Configuring the Video Camera
If a video camera is to be used, select “Video Camera” from the “Add Configuration” list. Note that before
this can be configured, The MVN reference camera, must be plugged into the mains power supply and
to the network connector of the pc or laptop in use. MVN Studio should automatically detect the camera
(if not, use the command “Scan for cameras”). If using a MVN (BIOMECH) Link system, connect the
camera Ethernet cable into the Access Point and connect the AP directly to the Computer via Ethernet.
7.3.1 Configuration
Changing the video configuration is effectively changing the frame rate.
MVN Studio supports VGA, video data will always be in color, with a resolution of 640 x 480.
To avoid flickering due to artificial lighting related to the mains frequency (50 Hz in Europe, 60 Hz in
USA), select the appropriate frame rate (25 or 50 fps for Europe or 30 or 60 fps for USA).
Note that unless using a high performance computer with a fast HDD, it is advised that a lower frame
rate is chosen (25 or 30 fps).
