The sensorimotricité platform of Paris Descartes University is on 7th floor in Saints-Pères. It is operational since November 2007. The platform has 200 m2 local room including a large room  used to record the subjects, a waiting room, a bathroom with a WC, a doctor’s office, a researcher’s office and an engineer’s office. Our 4 partners are the CNRS, INSERM, Paris Descartes University and IFR Handicap. We have had 500 000€ since 2007 to equip the platform. A Motion Capture and Movement Analysis system is available in the platform. It includes 6 units of 3D active motion capture device Codamotion CX1 for measuring body movement, 32ch Delsys EMG high-performing device Trigno Wireless System for the muscle activity detection, 2 force platforms AMTI for the pressure centre measure. One Immersion 3D visual projection system provides the visual input during a movement. The equipments are used for research to investigate motor control and sensorimotor transformations in healthy Human, in high-level athletes, in astronauts and patients. Different medical field are concerned in the latter case:  ENT, psychiatry, neurology, rehabilitation. The users are the researchers from the EPST, coach, members of the space agency and PU-PH from various hospital departments. They have published altogether more than fifty papers in various journals since the opening of the sensorimotricité platform.

The scientific projects on the platform can require either a CPP, an authorization from the CERES if minimally invasive or are reviewed by the staff of the platform if they are not invasive at all. The platform allows studies on populations of various age, from infants to senior.


Codamotion Système capture de mouvement 3D

Codamotion CX1 Technical Datasheet

The CX1 sensor unit is at the heart of every Codamotion 3D system for indoor applications.

Uniquely, the CX1 combines three motion sensing MLA’s into one unit. This allows a standalone CX1 unit to make a complete 3D measurement without reference to any other units. It also means that the unit can be pre-calibrated and sealed. All the user does is to point the unit at the action.

Advanced Technology

Each Masked Linear Array (MLA) measures the pattern produced when the flash of an active marker casts a shadow on its sensor array through a grid of lines (the mask). Its extreme accuracy comes from measuring patterns of illumination across its whole array surface, not just the fraction used when, for example, a focused dot falls on a 2D camera array.The MLA doesn’t suffer from non-linear distortions caused by camera lenses and has an acceptance angle of over 75 degrees, allowing more measurement volume in less space, with sensor units placed closer to the action for added accuracy.

Summary Specifications (3D measurement from a single CX1 Unit)

● Physical Dimensions Weight of unit: 5kg Dimensions (L x W x D): 800x112x80mm

● Resolution Standard deviation in position of a static marker at 3m range (axes as Figure 2): ˃ 0.05mm (X and Z axes) ˃ 0.3mm (Y axis) Resolution as fraction of field of view: ˃ 1:70,000 (X and Z axes) ˃ 1:12,000 (Y axis)

● Sampling Rates vs. Marker Numbers ˃ 100Hz for 56 markers ˃ 200Hz for 28 markers˃ 400Hz for 12 markers˃ 800 Hz for 6 markers

● Real-Time Latency ˃ 0.5 milliseconds for applications using CODA SDK.˃ 5-10 milliseconds using Codamotion Analysis or ODIN software suites.

● Capture Volume ˃ The linear capture range expands at approximately 1.6 x the distance from the CODA unit. Maximum accuracy is achieved between 2.0m and 4.5m from the unit, as in Figure 3. ˃ The total capture volume within which maximum accuracy is maintained = 75 cubic metres.

Il est important de noter qu’eu égard aux contraintes réglementaires, la plate forme a en fait deux usages. D’abord, elle sert à mettre au point des protocoles, qui sont ensuite transférés en milieu clinique. Ensuite, elle peut héberger des études qui sont entièrement réalisées sur place.
