  • Patent number: 11694300
    Abstract: Embodiments shifts the color fields of a rendered image frame based on the eye tracking data (e.g. position of the user's pupils). An MR device obtains a first image frame having a set of color fields. The first image frame corresponds to a first position of the pupils of the viewer. The MR device then determines a second position of the pupils of the viewer based on, for example, data receive from an eye tracking device coupled to the MR device. The MR device generates, based on the first image frame, a second image frame corresponding to the second position of the pupils. The second image frame is generated by shifting color fields by a shift value based on the second position of the pupils of the viewer. The MR device transmits the second image frame to a display device of the MR device to be displayed thereon.
