Abstract: This document describes techniques that enable facilitating user-proficiency in using radar gestures to interact with an electronic device. Using the described techniques, an electronic device can employ a radar system to detect and determine radar-based touch-independent gestures (radar gestures) that are made by the user to interact with the electronic device and applications running on the electronic device. For the radar gestures to be used to control or interact with the electronic device, the user must properly perform the radar gestures. The described techniques therefore also provide a tutorial or game environment that allows the user to learn and practice radar gestures in a natural way. The tutorial or game environments also provide visual feedback elements that give the user feedback when radar gestures are properly made and when the radar gestures are not properly made, which makes the learning and practicing a pleasant and enjoyable experience for the user.
