An artificial reality system is described that renders, presents, and controls user interface elements within an artificial reality environment, and performs actions in response to one or more detected gestures of the user. The artificial reality system includes an image capture device configured to capture image data representative of a physical environment, a head-mounted display (HMD) configured to output artificial reality content, a gesture detector configured to identify, from the image data, a gesture comprising a configuration of a hand that is substantially stationary for at least a threshold period of time and positioned such that a thumb of the hand and at least one other finger form approximately a circle or approximately a circular segment, a user interface (UI) engine to generate a UI element in response to the identified gesture, and a rendering engine to render the UI element as an overlay to the artificial reality content.
