Radial gesture navigation
Systems and methods for radial gesture navigation are provided. In example embodiments, user input data is received from a user device. The user input data indicates a continuous physical user interaction associated with a display screen of the user device. An initial point and a current point are detected from the user input data. A radius distance for a circle that includes the current point and is centered about the initial point is determined. An action is selected from among multiple actions based on the radius distance being within a particular range among successive ranges along a straight line that starts at the initial point and extends through the circle. Each range among the successive ranges corresponds to a particular action among the multiple actions. The selected action is performed in response to detecting a completion of the continuous physical user interaction.
