MyEyedro User Guide
A Display Group is a grouping of Device data sources (sensors) for display. Display Groups provide flexibility when presenting data collected from various sensors. They allow sensors (of the same type) from multiple Devices to be separated or combined for presentation in the MyEyedro Plugins.
A Device is a physical or virtual device containing one or more sources of data (i.e. sensors). Please see Appendix B for a list of supported devices.
Simply put, Devices are used to collect data and Display Groups are used to display the collected data.
