This invention relates to the field of smart terminal technology and discloses a display device and a display control method. The display device includes a display and a controller configured to: when playing first media data with first media data parameters in a first projection window of a projection interface, in response to a second operation command for playing second media data in a second projection window, acquire second media data parameters of the second media data; if it is determined that the second media data does not meet the projection conditions, stop receiving the first media data and control the display to play the second media data in the second projection window; if it is determined that the second media data meets the projection conditions, control the display to continue playing the first media data in the first projection window and play the second media data in the second projection window. Applying this solution can improve the user's projection experience.

The invention discloses a pupil and reflected light spot adaptive tracking method and system fusing multiple sensors, and belongs to the field of eye movement tracking signal processing. The eye movement tracking device generates cornea reflection light spots and collects images and events of the eyes; respectively obtaining a light spot template, a light spot coordinate list and a pupil fitting ellipse according to the image; in the eye movement tracking stage, events are screened according to the pupil fitting ellipse and the light spot template, and pupil events and light spot events are obtained; according to the pupil event, sequentially obtaining a pupil moving direction angle and a light spot event template at the current moment, and further obtaining a light spot candidate position; screening the light spot candidate positions according to the light spot coordinate list at the previous moment so as to update the light spot coordinate list and the light spot template; and finally, comparing pupil fitting ellipse axis length changes at two moments before and after, and judging whether eye movement tracking is ended or not. According to the invention, by fusing the frame image and the event stream, pupil and light spot tracking with high precision and high time resolution is realized.
