Improved Autocorrelate Events pipeline operation

Location: Pipeline Tools pane > Events & Timebar > Autocorrelate Events pipeline operation > Advanced Properties > Correlation Method

You can now choose the correlation method to automatically place events at the correct location in the time bar. check

To choose the required correlation method:

1. With a trial loaded in Nexus, in the Pipeline Tools pane, either
   • Expand Events & Timebar and add the Autocorrelate Events pipeline operation to the current pipeline.
     or
   • Select the Plug-in Gait Dynamic pipeline and then select the Autocorrelate Events operation.
2. With Autocorrelate Events selected, in the Properties pane, ensure that Advanced properties are displayed and then click in the Correlation Method field to select from the options:
   
   
   
   • Legacy
     Maximizes sum(xy)/(sum(x^2)+sum(y^2))
   • Least Squares
     Minimizes sum(x^2-y^2)/n
   • Pearson Coefficient
     Maximizes sum((x-<x>)(y-<y>)/sqrt((x-<x>)^2 (y-<y>)^2)
     
     Where <x> indicates the mean of x over the sample range
     
     
3. Ensure the other properties are as required and then run the pipeline.

Ability to identify selected Blue Trident devices in the 3D workspace

In the 3D Perspective view pane, Nexus 2.10.1 indicates the Blue Trident devices you've selected so that you can identify which set of axes correspond to each device when the names of the devices are not visible.

When a Blue Trident is selected, the color of the border around the label of the selected device changes from white to the color selected in the General View Options (see below), in the following example, blue (the default color).

Blue Trident devices that aren't selected are displayed with a white border.

To change the color for selected devices:

• In the Options dialog box (F7), select General View Options in the left column and in the Properties on the right, under General Colors click the Selected color to change it.

For a description of the other features and enhancements that have been released since Nexus 2.0, see the other Nexus What's New PDFs.

Full integration of Blue Trident sensor (IMU) data

Location: System Resources tab > Devices

Blue Trident is the latest Vicon Inertial Measurement Unit (IMU).

Nexus 2.10 provides full integration of Blue Trident sensor data, enabling you to:

• Use a higher number of sensors (up to 18) than was previously possible.
• Stream and capture Blue Trident data including global angles.
• Synchronize your IMU sensor data to your Vicon system:
  
  • Use hard sync for a high degree of precision, and with high sensor counts (Vicon Beacon required)
  • Use soft sync via Bluetooth, for systems where no Beacon is present
• Within Nexus, align IMUs to the Vicon world.

For information on how to use Blue Trident sensors with Nexus 2.10, see:

Vicon Nexus User Guide

• Configure Vicon IMUs
• Work with Vicon IMUs

To find out more about Blue Trident sensors, see the Vicon video, Capture.U Tutorial - Unboxing Blue Trident, available on YouTube.

Ability to include Tobii Eye Tracker

Location: System Resources tab > Devices > Add Digital Device > Add Tobii Pro Glasses 2

Nexus 2.10 lets you directly integrate a Tobii Eye Tracker in your Vicon system, enabling you to output eye tracker position and gaze direction, with binocular gaze tracking.

For information about setting up and using Tobii Pro Glasses 2 with Nexus, see Use Tobii Eye Tracker with Nexus in the Vicon Nexus Reference Guide.

Stream data in Open Sound Control format

Location: System Resources tab > Local Vicon System > Advanced properties > OSC Stream section

Nexus 2.10 enables you to stream data from Nexus over UDP using the Open Sound Control format, so that you can access live data in your OSC server application.

For more information, see OSC Stream section in the Vicon Nexus Reference Guide.
