摘要： According to the invention, a system for presenting graphics on a display device is disclosed. The system may include an eye tracking device and a graphics processing device. The eye tracking device may be for determining a gaze point of a user on a display device. The graphics processing device may be for causing graphics to be displayed on the display device. The graphics displayed on the display device may be modified such that the graphics are of higher quality in an area including the gaze point of the user, than outside the area.

摘要： Visualizable data (Din) are obtained that represent a scene (S) with at least one object (110, 120, 130). The visualizable data (Din) describe the scene (S) as seen from a position (P). First and second measures (L1; L2) are determined, which represent extensions of one of the objects (110) in a smallest and a largest dimension respectively. An object aspect ratio (R) is calculated that represents a relationship between the first and second measures (L1; L2). Based on the object aspect ratio (R), a selection margin (M) is assigned to the object (110). The selection margin designates a zone outside of the object (110) within which zone the object (110) is validly selectable for manipulation in addition to an area (A11) of the object (110) shown towards a view (V) thereof as seen from the position (P). Thus, it is made easier to manipulatable the visualizable data (Din) in response to user input, for instance in the form of gaze-based selection commands.

摘要： Disclosed is a method for switching user input modality of a displaying device displaying an interactable region. The displaying device is in communication with a first input modality and a second input modality. The first input modality is an eye tracker configured to determine gaze data of a user and the second input modality is an input modality other than an eye tracker configured to determine a pointing ray. The first input modality is selected as the input modality of the displaying device. The method comprises determining whether the pointing ray of the second input modality is intersecting with the interactable region. The method further comprises, based on the determining switching the input modality of the displaying device to the second input modality when the pointing ray of the second input modality is intersecting with the interactable region.

摘要： According to the invention, a system for presenting graphics on a display device is disclosed. The system may include an eye tracking device for determining a gaze point of a user on a display device. The system may also include a graphics processing device for causing graphics to be displayed on the display device. The graphics displayed on the display device may be modified such that the graphics in an area including the gaze point of the user have at least one modified parameter relative to graphics outside the area. The size of the area may be based at least in part on an amount of noise in the gaze point over time and at least one other secondary factor.

摘要： An augmented reality, virtual reality, or other wearable apparatus comprises an eye tracking device comprising an image sensor, a lens, and one or more processors. In some embodiments, the lens comprises a marker, and the one or more processors are configured to receive an image from the image sensor, wherein the image shows the marker, determine a distance from the image sensor to the marker based on the image, and change a calibration parameter of an eye tracking algorithm based on the distance. In some embodiments, the one or more processors are configured to receive image data from the image sensor, wherein the image data corresponds to an image as observed through the lens, determine a level or pattern of pincushion distortion in the image based on the image data, and change a calibration parameter of an eye tracking algorithm based on the level or the pattern of pincushion distortion.
