Segment Velocity
Segment velocity is an interesting biomechanics parameter, particularly for sports applications. In this tutorial, we focus on what segment velocity actually is, the different ways we can report it, and the meaning of the associated data.
Compute Model Based Data: Segment Velocity
In order to calculate segment velocity, the most reliable method is to use Compute Model Based Data. As one of the model based items available in the command, segment velocity can be calculate with respect to different segments using the resolution coordinate system of choice.
Compute Model Based Data: Segment Center of Gravity, Proximal Joint, and Distal Joint
One of the key features of Visual3D is the ability to track landmarks accurately. However, as you build your pipelines, you may be interested in knowing the relative position of a point on a segment. In this tutorial, we show you how to use Compute Model Based Data to obtain the coordinates of the center of gravity, proximal joint, and distal joint of a segment. We also show you how to do this with respect to another segment, and show you some tricks by creating virtual segments in your biomechanical model.
Segment Center of Gravity, Proximal Joint, and Distal Joint
Tracking specific positions of a segment, can be a very useful skill in biomechanics. In this tutorial, we explain why track the position of the segment center of gravity, proximal joint, and distal joint.
Compute Model Based Data: Joint Power
A common but misunderstood biomechanical calculation is joint power. As a feature in Compute Model Based Dataj we have scientifically validated methods to obtain it. However, it is important to understand that both of these model based items are to calculate scalar values. In this tutorial, we explore how to use Joint_Power and Joint_Power_Scalar and explain the difference between them.
Joint Power
Joint power can be a difficult concept to interpret that is often used in biomechanics. In this tutorial, we aim to shed some light on what joint power is, and how it is genuinely very useful to consider regardless of what biomechanical field you are in.
Joint Velocity
Joint velocity is often used in biomechanics to understand the kinematics between body segments. However, it is not quite as simple to interpret as just taking the first derivative of joint angle. There are several factors to consider, including understanding resolution coordinate systems, so we used this tutorial to highlight what joint velocity is.
Compute Model Based Data: Joint Velocity
The features in Compute Model Based Dataj offer a lot of scientifically validated calculations. However, it is also important to understand how to apply them. When it comes to joint velocity, it is no different, so in this tutorial, we explain how to set up the command to get the data you want.
