To start Capture.U and choose the way in which you want to collect data:

On your iOS device, start Capture.U.
If you need to upgrade the firmware for your Blue Trident sensors, the sensors are displayed with a yellow warning symbol and a warning message is displayed. For more information, see Update IMU firmware.
Tap to choose a collection mode, or to access the Learn components.

Your choice of collection mode depends on the number of sensors you want to use, the range you require and the type of output you want:

For unlimited range and up to 20 sensors, with reference video data directly from the device, choose To Sensor. After you have captured the data, download it to your computer with Capture.U Desktop for further analysis.
For data that is saved directly to your device (where the capture range is constrained by the Bluetooth^® range of the device), choose To Device or Real-Time Insight mode.
To explore Apple’s ARKit video-based visualization (the iOS device must be compatible with Apple ARKit 3), choose AR Visualization mode.
For access to the Learn mode components, choose Education for an interactive guide that explains how each sensor works and its outputs; or Practice for practical applications involving common human movements, and help in understanding and analyzing IMU outputs.

Note
In all collection modes, there may be a lag in data frames (a small offset) between sensors when starting collection, but the data will be synced.

The modes are explained in more detail in the following sections:

Important
If you plan to collect global angles, after the sensors are attached to a subject, allow a few seconds for onboard calibration to initiate before starting the movement that is to be collected.
