Optotrak 3020 motion capture system

Manufactured by Northern Digital

Sourced in Canada

The Optotrak 3020 Motion Capture System is a high-precision, non-contact measurement device designed to capture and analyze three-dimensional motion data. The system employs an array of infrared cameras to track the positions of specialized markers attached to a subject or object, providing real-time, quantitative data on the movement and kinematics of the target.

Three-Dimensional Kinematic Analysis of Lip and Jaw Movements

High-quality audio and video recordings were obtained for the analysis of phonetic accuracy. Simultaneously, three-dimensional kinematic data were collected at 250 samples/second using a three-camera Optotrak 3020 motion capture system or 3D Investigator motion capture system (both Northern Digital Inc., Waterloo, Ontario, Canada). Small (6 mm) infrared light emitting diodes (IREDs) were attached with anti-allergenic medical adhesive to each participant’s upper lip, lower lip, and a lightweight splint under the chin at midline to approximate jaw movement. Five additional IREDs were used to create a three-dimensional head coordinate system in order to subtract head motion artifact (Smith, Johnson, McGillem, & Goffman, 2000 ). A time-locked acoustic signal was collected at 16,000 samples/second to confirm that movement records aligned with target nonword productions.

Humerus Fracture Motion Tracking

Check if the same lab product or an alternative is used in the 5 most similar protocols

An Optotrak 3020 Motion Capture System (Northern Digital Inc, Waterloo, Ontario, Canada) was used to measure 3D translations and rotations of the fractured fragment relative to the body of the humerus, throughout experimentation. This motion tracking system has an accuracy of 0.1 mm and a resolution of 0.01 mm at a distance of 2.25 m [6 (link), 7 (link), 14 (link), 16 (link)]. Two LED-motion flags were attached to each specimen, one to the proximal humerus and the other to the distal fractured fragment (Fig. 3). Seven points on each side of the fracture, that is, on both the proximal humerus and distal fragments, were digitized to determine critical fracture surface positions in space (Fig. 4). Motion was sampled throughout position changes of the forearm.Fig. 4

3D Gait Kinematics Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols

Gait kinematics were measured with an Optotrak 3020 Motion Capture System (Northern Digital Inc., Waterloo, Ontario, Canada). 3D coordinates were obtained from infrared light emitting markers placed bilaterally on the foot (fifth metatarsal head), ankle (lateral malleolus), knee (lateral joint space), hip (greater trochanter), pelvis (iliac crest), and shoulder (acromion process). Wearing their usual comfortable shoes, subjects were asked to walk for 3-5 trials along the 10 foot laboratory walkway as quickly and safely as possible. Walk velocity was computed using a custom-made MATLAB (The MathWorks Inc., Natick, Massachusetts, USA) program. Individuals who regularly used an ankle-foot orthosis or an assistive device for safety were permitted to use it during all walking trials.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
