Optotrak system

Manufactured by Northern Digital

Sourced in Canada

The OPTOTRAK system is a motion capture technology that utilizes optical tracking to precisely measure the three-dimensional position and orientation of objects. The system is designed to capture the movement of targets attached to objects, providing real-time data on their spatial coordinates.

Eye movements were recorded for 5 s from the onset of each trial.
The 3D positions of the right hand were recorded using an OPTOTRAK system (Northern Digital, Waterloo, Ontario, Canada) sampling the two infrared emitting diodes (IREDs) on the participants hand at a rate of 100 Hz for a minimum of 5 s from the onset of each trial.

Kinematic Analysis of Lower Limb

Infrared emitting diodes were placed on the right ankle (lateral malleolus), right knee (fibular head), right hip (greater trochanter) and the right shoulder (acromion process) and measured at 120 Hz by a 3-camera Optotrak system (Northern Digital, Inc.) placed approximately 4 meters behind the subject. Platform angle was recorded midway between medial/lateral extremes of the platform and in line with the axis of rotation of the platform. These data were stored on a personal computerfor offline analysis.

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.
