A method for eye tracking calibration comprising: under control of a hardware processor: identifying an eye calibration target (1282, 1354) at a fixed location in a world space associated with an environment of a user; instructing a wearable device of the user configured to be worn on the head of the user to render a virtual reticle (1284, 1352) in a rig space associated with the wearable device of the user, wherein the virtual reticle (1284, 1352) and the eye calibration target (1282, 1354) are viewable through a display of the wearable device, and wherein the rig space has a spatially fixed relation to the wearable device; characterized in that the method further comprises: obtaining head pose data of the user; determining a current head pose of the user based on the obtained head pose data; determining a relative position of the virtual reticle (1284, 1352) with respect to the eye calibration target (1282, 1354) based at least partly on the user's current head pose; determining whether the virtual reticle (1284, 1352) aligns with the eye calibration target (1282, 1354) based at least in part on the relative position of the virtual reticle with respect to the eye calibration target; and in response to a determination that the virtual reticle aligns with the eye calibration target, instructing an inward-facing imaging system of the wearable device to acquire eye calibration data. under control of a hardware processor: identifying an eye calibration target (1282, 1354) at a fixed location in a world space associated with an environment of a user; instructing a wearable device of the user configured to be worn on the head of the user to render a virtual reticle (1284, 1352) in a rig space associated with the wearable device of the user, wherein the virtual reticle (1284, 1352) and the eye calibration target (1282, 1354) are viewable through a display of the wearable device, and wherein the rig space has a spatially fixed relation to the wearable device; characterized in that the method further comprises: obtaining head pose data of the user; determining a current head pose of the user based on the obtained head pose data; determining a relative position of the virtual reticle (1284, 1352) with respect to the eye calibration target (1282, 1354) based at least partly on the user's current head pose; determining whether the virtual reticle (1284, 1352) aligns with the eye calibration target (1282, 1354) based at least in part on the relative position of the virtual reticle with respect to the eye calibration target; and in response to a determination that the virtual reticle aligns with the eye calibration target, instructing an inward-facing imaging system of the wearable device to acquire eye calibration data. identifying an eye calibration target (1282, 1354) at a fixed location in a world space associated with an environment of a user; instructing a wearable device of the user configured to be worn on the head of the user to render a virtual reticle (1284, 1352) in a rig space associated with the wearable device of the user, wherein the virtual reticle (1284, 1352) and the eye calibration target (1282, 1354) are viewable through a display of the wearable device, and wherein the rig space has a spatially fixed relation to the wearable device; characterized in that the method further comprises: obtaining head pose data of the user; determining a current head pose of the user based on the obtained head pose data; determining a relative position of the virtual reticle (1284, 1352) with respect to the eye calibration target (1282, 1354) based at least partly on the user's current head pose; determining whether the virtual reticle (1284, 1352) aligns with the eye calibration target (1282, 1354) based at least in part on the relative position of the virtual reticle with respect to the eye calibration target; and in response to a determination that the virtual reticle aligns with the eye calibration target, instructing an inward-facing imaging system of the wearable device to acquire eye calibration data. obtaining head pose data of the user; determining a current head pose of the user based on the obtained head pose data; determining a relative position of the virtual reticle (1284, 1352) with respect to the eye calibration target (1282, 1354) based at least partly on the user's current head pose; determining whether the virtual reticle (1284, 1352) aligns with the eye calibration target (1282, 1354) based at least in part on the relative position of the virtual reticle with respect to the eye calibration target; and in response to a determination that the virtual reticle aligns with the eye calibration target, instructing an inward-facing imaging system of the wearable device to acquire eye calibration data.
