Problems solved by technology

[0003] However, using such a special mode to zoom in on a content item incurs additional steps and corresponding user input to prepare the display and the desired item for selection
Thus, utilizing such a mode undesirably increases the delay between the user's formation of a desire to select an item and the actual selection of that item

Embodiment Construction

[0016] figure 1 A schematic diagram of one embodiment of the user interface system 10 for locating target indicators displayed via the display system 14 is shown. User interface system 10 includes positioning module 18 , which may be stored in mass storage device 20 of computing device 22 . Positioning module 18 may be loaded into memory 26 and executed by processor 28 of computing device 22 to implement one or more of the methods and processes described in more detail below.

[0017] Computing device 22 may receive gaze tracking data 30 from gaze tracking system 34 and user input 40 from user actuatable input tracking system 42 . As described in more detail below, in various embodiments, gaze tracking system 34 may be located on a head-mounted computing device, tablet, notebook, smartphone or other mobile computing device, desktop computing device, stand-alone monitoring device, with or without an integrated display. computer, wall-mounted monitor, interactive whiteboard, g...

Abstract

Embodiments that relate to positioning a target indicator via a display system are disclosed. For example, one disclosed embodiment provides a method for positioning a target indicator using gaze tracking data having a coarse accuracy from a gaze tracking system of a computing device. Head pose data having a fine accuracy greater than the coarse accuracy is received from a head tracking system. Using the gaze tracking data, an approximate user gaze region within a display region is determined, and the target indicator is displayed at an initial location within the approximate user gaze region. A reposition input from the user is received. In response, subsequently received head pose data is used to calculate an adjusted location for the target indicator. The target indicator is then displayed at the adjusted location.

Description

Background technique [0001] Navigating electronic content to discover and select relevant portions of the content is a frequently performed task. In some examples, a gaze tracking system and associated eye-gaze interface may enable a user to navigate through content items displayed to the user via a display device. Some content items may be selectable by a user via an input device (eg, mouse, keyboard, or other mechanism). [0002] However, such gaze tracking systems may have limited accuracy and resolution. These limitations may negatively affect the user's experience with the eye-gaze interface. For example, effective interaction via an eye-gaze interface with limited accuracy can prove challenging when selectable content items are displayed at smaller sizes. In some cases, when two or more selectable content items are displayed close to each other and at a smaller size, it may be difficult or practically impossible to navigate to and select a desired item using an eye-ga...
