Abstract: An electronic device having a display on one side of the device and one or more image sensors on the opposite side of the device captures image data using the one or more image sensors. The display displays a portion of the captured image data on the display and a first graphical object overlaid on the displayed portion of the captured image data. A user gesture is detected using the one or more image sensors. In accordance with a determination that the detected user gesture meets a set of criteria, a position of the graphical object is updated based on the user gesture or is the first graphical object is replaced with a second graphical object. In accordance with a determination that the detected user gesture does not meet a set of criteria, the display of the first graphical object is maintained.
