Feedback Node

The Feedback Node triggers a UI-Overlay, which covers the whole smartphone screen and displays feedback to the user. Therefore its recommended use is for especially important textual feedback, where a simple red blinking outline would not be sufficient. In the node, a header text and the feedback text have to be specified. The overlay stays open until the user has read it and taps Understood; while it is open, the interaction buttons are hidden.

From the didactic perspective, this is intended to be used to provide feedback to the user of the training: Telling the user what they did wrong or what they could do to continue. For more detail, read our publication on the TrainAR interaction concept and didactic framework: "TrainAR: A Scalable Interaction Concept and Didactic Framework for Procedural Trainings Using Handheld Augmented Reality"
