Head Pose Control for Near-Eye Display Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted devices with near-eye displays face challenges in providing effective touch input due to their positioning close to the user's eyes, making it difficult to control device settings.
Innovation Solution
The use of head pose information to adjust scalar quantities of device settings, such as speaker volume or display brightness, by updating visual representations of sliders on the display, allowing users to control settings without physical touch input through changes in yaw, roll, and pitch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If near-eye displays are positioned close to the user's eyes, then the display visibility and immersion are improved, but the ability to provide touch input deteriorates
Solution Approach 1:
The patent replaces the mechanical touch input system with a gaze-based control system. Sensors detect the user's gaze direction and head pose to determine user intent, substituting the need for physical contact with the display surface. This allows full utilization of the near-eye display's visual capabilities while enabling control through head movements rather than tactile interaction.
Solution Approach 2:
The patent introduces gaze detection technology as an intermediary between the user and the display control functions. The sensor system acts as a mediator that translates gaze direction into control commands, enabling users to interact with the display without direct contact. This intermediary layer resolves the contradiction by providing a non-contact control method that works seamlessly with the near-eye display positioning.
2Area of stationary object
If the display is positioned near the eyes, then the field of view and user experience are improved, but the accessibility for control deteriorates
Solution Approach 1:
The patent substitutes mechanical control interfaces (buttons, touch surfaces) with a gaze-based control mechanism. This allows the display to maintain its optimal near-eye positioning for maximum field of view while enabling users to control device settings through natural head movements and gaze direction, eliminating the need for physical accessibility to control elements.
Solution Approach 2:
The patent makes the gaze detection system serve multiple functions: it detects user attention, determines control intent, and enables device setting adjustments. This multi-functional approach allows the system to maintain the near-eye display configuration for optimal field of view while providing universal accessibility for control through a single, integrated gaze-based interface.

AI summary
A head-mounted device may use head pose changes for user input. In particular, a display in the head-mounted device may display a slider with an indicator. The slider may be a visual representation of a scalar quantity of a device setting such as volume or brightness. Based on head pose changes, the scalar quantity of the device setting and the position of the indicator on the slider may be updated. The direction of a head movement may correspond to the direction of movement of the indicator in the slider. The scalar quantity of a device setting may only be updated when gaze input from a user targets the slider. The slider may be displayed in response to gaze input targeting an icon associated with the slider.
