The invention discloses a cursor anti-shake method. The method includes: acquiring theoretical displacement of a cursor displayed in a display interface of head-mounted display equipment in a detection period and generated by responding to movement of the head-mounted display equipment according to the preset detection period; judging whether an absolute value of the theoretical displacement is less than a first preset distance or not; if yes, updating display position of the cursor in the display interface according to the theoretical displacement; if not, maintaining the display position ofthe cursor in the display interface unchanged. Correspondingly, the invention further provides a cursor anti-shake device, a storage medium and the head-mounted display equipment. By adopting the embodiments of the invention, shaking of the cursor due to shaking of the head-mounted display equipment can be prevented.
