Abstract: A display system, a method for processing a trajectory point sequence, a storage medium, and a device are provided. The display system includes a display, a processor, and an input component. The processor is configured to control the display to display an interaction interface; receive a trajectory point sequence input by a user by means of the input component; generate a first content based on the trajectory point sequence and control the display to display the first content; recognize a first identification sequence included in the trajectory point sequence, to determine a first feature identifier corresponding to the first content; determine a cluster relationship of the first content according to the first feature identifier; generate a display region in a preset format according to the cluster relationship; and control the display to display the display region on the interaction interface.
