Dynamic calibration systems and methods for wearable heads-up displays

Abstract

Systems, methods and articles that provide dynamic calibration of eye tracking systems for wearable heads-up displays (WHUDs). The eye tracking system may determine a user's gaze location on a display of the WHUD utilizing a calibration point model that includes a plurality of calibration points. During regular use of the WHUD by the user, the calibration point model may be dynamically updated based on the user's interaction with user interface (UI) elements presented on the display. The UI elements may be specifically designed (e.g., shaped, positioned, displaced) to provide in-use and on-going dynamic calibration of the eye tracking system, which in at least some implementations may be unnoticeable to the user.

Description

BACKGROUNDTechnical Field[0001]The present disclosure generally relates to wearable heads-up displays, and more particularly, to calibration systems and methods for eye tracking systems of wearable heads-up displays.Description of the Related Art[0002]Wearable Heads-Up Displays[0003]A head-mounted display is an electronic device that is worn on a user's head and, when so worn, secures at least one electronic display within a viewable field of at least one of the user's eyes, regardless of the position or orientation of the user's head. A wearable heads-up display is a head-mounted display that enables the user to see displayed content but also does not prevent the user from being able to see their external environment. The “display” component of a wearable heads-up display is either transparent or at a periphery of the user's field of view so that it does not completely block the user from being able to see their external environment. Examples of wearable heads-up displays include: ...

AI Technical Summary

Benefits of technology

The invention is about a wearable heads-up display device (WHUD) that can display user interface (UI) elements on its display. The device can detect the user's gaze location by using glint information and a known location of the display. The display can be populated with multiple UI elements that are arranged to maximize the distance between them or minimize the similarity between vectors that join pairs of UI elements. The technical effect of this invention is to provide a more efficient and user-friendly interface for wearable displays by optimizing the placement of UI elements on the display.

Problems solved by technology

A wearable heads-up display is a head-mounted display that enables the user to see displayed content but also does not prevent the user from being able to see their external environment.

Independent of their performance limitations, many of the aforementioned examples of wearable heads-up displays have struggled to find traction in consumer markets because, at least in part, they lack fashion appeal.

Most wearable heads-up displays presented to date employ large display components and, as a result, most wearable heads-up displays presented to date are considerably bulkier and less stylish than conventional eyeglass frames.

A challenge in the design of wearable heads-up displays is to minimize the bulk of the face-worn apparatus while still providing displayed content with sufficient visual quality.
