A data processing apparatus includes avatar monitoring circuitry to receive gaze data for a first user associated with a first avatar in a virtual reality environment, the gaze data for the first user indicative of a gaze point for the first user with respect to the virtual reality environment, in which the avatar monitoring circuitry is configured to select one or more objects in the virtual reality environment in dependence upon the gaze data for the first user and to store first avatar information for the first avatar indicative of one or more of the selected objects, input circuitry to receive gaze data for a second user indicative of a gaze point for the second user with respect to the virtual reality environment, and processing circuitry to generate one or more images for the virtual reality environment for display to the second user, in which the processing circuitry is configured to: select the first avatar in dependence upon the gaze point for the second user with respect to the first avatar; and generate the one or more images to include at least one graphical element indicative of the first avatar information in response to the selection of the first avatar.
