Abstract: Techniques for controlling light sources used in eye tracking are described. In an example, an eye tracking system generates a first image and a second image showing at least a portion of the user eye illuminated by a predetermined set of illuminators of the eye tracking system. The eye tracking system determines a first position of a glint in the first image and a second position of the glint in the second image. Each of the first position and the second position is relative to a pupil edge. The eye tracking system predicts a third position of the glint relative to the pupil edge based on the first position and the second position. Further, the eye tracking system determines, from the predetermined set, an illuminator that corresponds to the glint and determines, based on the third position, whether to power off the illuminator to generate a third image of at least the portion of the user eye.

Abstract: 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.
