In one implementation, a method of accessing shared data among processes is performed by a device including processor(s), non-transitory memory, and an image acquisition interface. The method includes obtaining image data acquired by the image acquisition interface. The method further includes determining pose data based at least in part on inertial measurement unit (IMU) information measured by the image acquisition interface. The method also includes determining a gaze estimation based at least in part on eye tracking information obtained through the image acquisition interface. Based at least in part on characteristics of processes, the method includes determining an arrangement for the image data, the pose data, and the gaze estimation. The method additionally includes determining an access schedule for the processes based at least in part on at least one of: the arrangement, the characteristics of the processes, and hardware timing parameters associated with the device.
