    Abstract: A line-of-sight detection device capable of achieving further improvement in line-of-sight detection accuracy, achieving low latency, and achieving low power consumption is provided. There is provided a line-of-sight detection device including an imaging element, an illumination unit that illuminates an eyeball with a plurality of beams of illumination light, an optical element that guides respective beams of reflected light in a plurality of directions from the eyeball caused by the plurality of beams of illumination light to a direction of the imaging element, an optical system that causes the imaging element to non-selectively receive the beams of reflected light in the plurality of directions from the eyeball, and a calculation unit that converts, on the basis of the beams of reflected light in the plurality of directions from the eyeball received by the imaging element, the beams of reflected light into information of eyeball movement and/or positional information of a pupil.

    Abstract: An information processing apparatus according to an embodiment of the present technology includes a line-of-sight estimator, a correction amount calculator, and a registration determination section. The line-of-sight estimator calculates an estimation vector obtained by estimating a direction of a line of sight of a user. The correction amount calculator calculates a correction amount related to the estimation vector on the basis of at least one object that is within a specified angular range that is set using the estimation vector as a reference. The registration determination section determines whether to register, in a data store, calibration data in which the estimation vector and the correction amount are associated with each other, on the basis of a parameter related to the at least one object within the specified angular range.

    Abstract: A display processing device includes a control unit (180) that causes a display device to display a spatial object indicating a virtual space. The control unit (180) determines movement of a user in a real space on the basis of a signal value of a first sensor, determines whether or not the user of the display device is gazing at the spatial object on the basis of a signal value of a second sensor, and controls the display device such that visibility of the virtual space indicated by the spatial object is changed on the basis of the determination that the user is gazing at the spatial object and the movement of the user toward the spatial object.
