1. An obstacle notification system for a work machine, comprising:
a processor configured to:
dispose a frame line in a display, the frame line having a predetermined shape and representing a detection range for an obstacle,
determine whether the obstacle is within the detection range,
give a notification indicating a presence of the obstacle based on determining that the obstacle is present within the detection range,
receive an operation on the display for changing the detection range,
change a size of the detection range by changing the predetermined shape of the frame line based on the operation on the display,
determine whether start coordinates of the operation on the display are in the detection range in which the obstacle is present,
based on determining that the start coordinates of the operation on the display are in the detection range in which the obstacle is present, change the size of the detection range based on the operation, and
ignore the operation based on determining that the start coordinates of the operation on the display are outside the detection range.
