What is Simi Motion® ?

Simi Motion provides an extensive platform for motion capture and 2D/3D movement analysis. Simi Motion can be tailored to the needs of the specific user. A range of configurations are possible to suit customers who would prefer to conduct quick and simple analyses as well as for those of a more scientific background, wishing to solve complex problems.

What makes Simi Motion® unique?

In comparison to the majority of products available on the market, Simi Motion uses no infrared technology but utilizes image based techniques. High quality video recordings with high frame rates and high resolutions are captured and saved using synchronized industrial cameras. Using the latest algorithms of image processing, Simi Motion can capture motion in detail and calculate 2D/3D data. As with the other systems, Simi Motion has marker based automatic tracking to calculate marker positions. It is however also possible to track using markerless methods, such as pattern matching or silhouette tracking using no markers. The years of research and development which Simi has invested in this area have enabled research, for which infrared systems simply do not suffice.

 

The operator of Simi Motion is able to use affordable industrial cameras. With Simi Software you receive the best data quality and operation speeds available. Image based technology is the future of movement analysis and Simi is the market leader in this area.

In which variations can I buy Simi Motion® ?

Simi Motion has a highly modular format, meaning that the software and setup can be adapted to suit your needs.

The three main variations of this product are:

  • 2D Analysis (simple use and quick results, 2D measurements)
  • Simple 3D Analysis (simple 3D configurations in the middle price range. High data quality for simple problems)
  • Complex 3D Analysis (for the most scientific requirements and complex measurements)

 

What is the operational procedure of Simi Motion® ?

Simi Motion offers the complete range of recording, processing, editing and analysis of data. The individual steps comprise of …

  1. Movement recordings with synchronised cameras, in addition to the logging of data from supplementary measuring devices such as EMG, force plates and others (if available)
  2. 2D or 3D movement data capture through the tracking of joint centres, with or without the use of markers.
  3. Movement data calculations (position, path, velocity, acceleration etc.)
  4. Movement and sensory data processing for the individual calculation of analysis parameters and evaluation
  5. Data analysis and reporting
  6. Data exportation into further programmes when necessary

 

 

  • inverse kinematics report 1
  • inverse kinematics report 2

What results do I get from Simi Motion® ?

Scientifically precise movement data for kinematics and kinetics (position, speeds, accelerations, angles, distances, etc) with synchronised data from additional measurement devices such as EMG measurements or force plates. This data can be processed further to obtain additional analysis parameters (further angles, mathematical calculations, filtered and rectified EMG data, phases, events, etc) according to requirements.

 

All results and calculations can be displayed in standard reports or in individual report drafts, but can also be stored in ASCII, C3D and other formats, to allow straight forward transportation into other programmes. For 3D animations, it is also possible to export files in certain 3D formats such as bvh, maya, lws and Filmbox.

In Simi Motion, it is possible to integrate a multitude of different data measurements which are key in movement analyses. The following equipment and brands are compatible with Simi Motion.

 

Analogue Equipment

Simi Motion can record any analogue signal through a suitable A/D Adapter in synchronisation with movement data from the video.

 

Digital Equipment

Equipment which produces digital signals can in general not be recorded directly by Simi Motion. The majority of equipment can however be synchronised with a hardware trigger, and the data can then be imported into Simi Motion. Digital equipment can be bound via your SDKs directly with Simi Motion, but success can vary with each individual case.

 

example of EMG data

EMG

Both digital and analogue equipment is available for EMG measurement. The recommendations above apply to the two different signal types. Brands which have been frequently used and well integrated include Noraxon, Mega Electronic, BioVision, Delsys and Myon.

force plate measurement data

Force Plates

Force plates provide analogue signals in most cases, and can therefore be directly recorded using Simi Motion. Typical brands are Kistler, AMTI oder Bertec.

data of foot pressure measurement

Foot Pressure Equipment

Foot pressure measuring equipment can be synchronised and then displayed in Simi Motion via the use of a hardware trigger. Equipment produced by Novel, Medilogic, RSScan, Tekscan, Parotec and Zebris have been integrated with our software in the past.

   

EEG

Even EEGs can be integrated and reported with Simi Motion. We have previous experience integrating equipment from Brain Products.
