This friendliness was not obtained at the expense of the functionalities and adaptation capabilities of the software. For instance, Movia includes a wizard allowing to define easily the configuration of the measurements to do. Movia also incorporates intuitive editors that can be used to define various views of the data captured (video, curves, graphs,...), in cases where the default views presented by Movia will not give plein staisfaction. |
Movia
includes a highly flexible feedback system allowing to monitor in real time the signals to capture and of course the video. This feedback mechanism can also be employed to present to the subjects informations during the expériments, like the forces vectors coming from platforms and overlayed to the video.

Acquired data can now be processed and/or displayed on some graphics of different types (y=f(temps), y=f(x),...) and the videos in parallel.
Cursors handled by the user allow to point a precise moment on the graphics and the videos, Movia guaranteeing permanently the correspondance
between the displayed images and the moment pointed on the graphics. Movia also integrates tools to analyse videos that allow to zoom in and out,
to make 2D measures on static images (angles, distances). .

When GenICam cmaeras from IDS are used with Movia, retro-reflective markers can be localized in 2D in real time. Their 2D trajectories and the kinegrams can be displayed in overlay of the video. Angles defined by the markers could be computed and displayed in graphs and also in overlay of the video. |

Movia is an open software containing many possibilities of impression, of data export and import under various forms. It can also import 3D data supplied by motion capture systems like SAGA-3RT, plantar pressure measurements (footscan) and temporal events (ProtoKinetics,...). External modules could easily be written (using Matlab, Excel, C/C++, .Net, ...) so that to increase the processing capabilities. These multiple techniques of data exchange constitute an efficient way to extend with no limits the possibilities of Movia and to answer to the demands of each user. |
