  • Patent number: 11899408
    Abstract: A pointer controller includes at least one processor; and a display that includes a pointer. The at least one processor is configured to control the display so as to display an elapsed time, switching between (i) a first display mode for display of the elapsed time cumulatively by causing, upon resumption of display, movement of the pointer that inherits a previous display time and (ii) a second display mode for display of the elapsed time non-cumulatively by causing, upon resumption of display, movement of the pointer that does not inherit the previous display time. The movement of the pointer controlled by the at least one processor is such that the first display mode and the second display mode differ from each other in a way of movement that indicates how the pointer moves.
