Display device viewer gaze attraction

A computing device for attracting a gaze of a viewer of a display device, the computing device comprising:

• a gaze attraction program executed by a processor of the computing device, the gaze attraction program configured to:
• control the display device to display a target object;
• monitor a gaze location of the viewer using gaze tracking data from a gaze tracking system;
• control the display device to display a guide element moving along a computed dynamic path that traverses within a predetermined region adjacent to the gaze location of the viewer and leads to the target object;
• using the gaze tracking data, determine if a gaze trajectory of the viewer is within a path divergence threshold of the computed dynamic path;
• if the gaze location of the viewer is within the path divergence threshold of the computed dynamic path, then control the display device to continue displaying the guide element moving along the computed dynamic guide path to the target object;
• and
• if the gaze location of the viewer diverts from the computed dynamic path by at least the path divergence threshold, then control the display device to discontinue the guide element moving along the computed dynamic path.

In a head-mounted display device worn by a viewer, a method for attracting a gaze of the viewer, the method comprising:

• controlling the head-mounted display device to display a target object;
• using gaze tracking data from a gaze tracking system of the head-mounted display device to monitor a gaze location of the viewer;
• controlling the head-mounted display device to display a guide element moving along a computed dynamic path that traverses within a predetermined region adjacent to the gaze location of the viewer and leads to the target object;
• using the gaze tracking data to determine if a gaze trajectory of the viewer is within a path divergence threshold of the computed dynamic path;
• if the gaze trajectory of the viewer is within the path divergence threshold of the computed dynamic path, then controlling the head-mounted display device to continue displaying the guide element moving along the computed dynamic guide path to the target object;
• and
• if the gaze trajectory of the viewer diverts from the computed dynamic path by at least the path divergence threshold, then controlling the head-mounted display device to discontinue displaying the guide element moving along the computed dynamic guide path to the target object.
