XR Focus Indicator for Head Motion Input Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for visualizing user interface elements in extended reality environments do not effectively convey to users that head motion controls are being used for selection, leading to unawareness of input success.
Innovation Solution
The method involves displaying a focus indicator that changes appearance and location in response to head pose changes, providing visual feedback within an extended reality environment to indicate selection progress and completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If head motion control is used for UI element selection without visual feedback, then the control mechanism remains invisible to users, but user awareness of input success deteriorates
Solution Approach 1:
The patent applies feedback by introducing visual indicators that respond to head motion inputs. The focus indicator changes appearance (e.g., color, size, or intensity) based on detected head pose changes, providing users with immediate visual confirmation that their head motion is being registered and processed for UI element selection.
Solution Approach 2:
The patent utilizes color changes as a specific form of visual feedback. The focus indicator transitions between different colors or color intensities to communicate the system's response to head motion, making the invisible control mechanism visible through chromatic variations that users can perceive.
2Loss of information
If visual feedback is provided for head motion input, then user awareness of input success improves, but the system complexity increases
Solution Approach 1:
The focus indicator serves multiple functions: it indicates which UI element is currently selected, provides visual feedback for head motion detection, and communicates input success status. By making this single element multi-functional, the patent reduces the need for additional separate components that would increase system complexity.
Solution Approach 2:
The patent merges the head motion detection feedback mechanism with the existing focus indicator that is already part of the UI. Instead of creating a separate feedback system, the head motion response is integrated into the visual appearance of the focus indicator, combining multiple functions into a unified element.

AI summary
In one implementation, a method for visualizing multi-modal inputs includes: displaying a first user interface element within an extended reality (XR) environment; determining a gaze direction based on first input data; in response to determining that the gaze direction is directed to the first user interface element, displaying a focus indicator with a first appearance in association with the first user interface element; detecting a change in pose of at least one of a head pose or a body pose of a user of the computing system; and, in response to detecting the change of pose, modifying the focus indicator from the first appearance to a second appearance different from the first appearance.
