In some aspects, a device includes a processor coupled to a camera module, a display, and a memory. The processor can be configured to cause the display to output a graphical user interface element including a first region. The processor can also receive, from a user input surface, a first input type including movement of an input element relative to the user input surface. The processor can control a first imaging operation based on the first input type and cause the first region to move relative to the user input surface while the first input type is received. The processor can control a second imaging operation based on a second input type, and the second input type can be received after the first input type. The second input type can include a selection of the first region by the input element. ## Claims ### Claim 1 A device comprising: a memory; and a processor coupled to an image sensor, a display having a user input surface, and the memory, the processor configured to: cause the display to output a graphical user interface, the graphical user interface including a first element;
