Abstract: An eyeball tracking method and a virtual reality device are disclosed. The eyeball tracking method is applied to the virtual reality device, the virtual reality device comprises at least two cameras, and shooting areas of the cameras are partially overlapped. The eyeball tracking method comprises the steps of: acquiring images captured by at least two cameras at a same moment; superimposing overlapping areas in the images to obtain a target image including an eyeball area; and performing eyeball tracking according to the target image. The accuracy of eyeball tracking can be improved.

Abstract: Disclosed are a near-eye display device, an eye command recognition method and a readable storage medium. The near-eye display device includes: an eyeglass frame, a lens and a transparent electrode layer; the lens is provided on the eyeglass frame, the transparent electrode layer is provided on a surface of the lens, and the transparent electrode layer is configured to detect capacitance changes at the position of the human eye. The eye command recognition method includes: controlling the transparent electrode layer of the near-eye display device to obtain capacitance information at the position of the human eye; determining motion of the human eye based on the capacitance information; and converting the determined motion of the human eye into control commands for controlling the near-eye display device.
