Wearable Display Field of View and User Interface Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computing devices face challenges in providing an intelligent, efficient, and intuitive user interaction experience, especially when dealing with media items that exceed the display size, requiring innovative solutions for navigating and interacting with information.
Innovation Solution
The system includes instructions for a display device to manage a field of view and user interface, allowing movement and alignment based on input data, enabling users to interact with media items through gestures and sensor inputs, and dynamically adjusting the display to maintain an unobstructed view while allowing access to menu items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the media item is zoomed or magnified to provide sufficient detail, then the detail visibility is improved, but the media item becomes too large to fit entirely on the display element
Solution Approach 1:
The media item is divided into multiple portions, with only a field of view portion displayed at a time on the display element. This allows the entire media item to be virtually expanded beyond the physical display boundaries while maintaining detailed visibility of the current portion.
Solution Approach 2:
The system transitions from displaying the entire media item in a single two-dimensional space to using a virtual three-dimensional space where the media item can be panned and zoomed. This allows detailed views without being constrained by the physical display area.
2Measurement precision
If the display element shows only a portion of the media item, then the detail visibility is improved, but the user must navigate or move throughout the media item to view different portions
Solution Approach 1:
The user interface elements (menu items, controls) are merged with the media item display in an integrated overlay. This allows users to access navigation and interaction functions without leaving the media item context, simplifying the overall interaction model.
Solution Approach 2:
The field of view and user interface elements are made dynamic and movable relative to the media item. Users can pan and zoom the field of view to different portions of the media item, and the UI elements adapt their positions accordingly, making navigation more intuitive and efficient.
3Ease of operation
If menu items are displayed at a top portion of the window, then the user interface is provided, but the menu items may obstruct the view of the media item
Solution Approach 1:
The user interface elements are overlaid on the media item in a layered dimensional space rather than occupying the same two-dimensional display space. This allows both the media item and UI elements to be visible simultaneously without mutual obstruction.
Solution Approach 2:
The user interface elements are dynamically positioned and can be moved independently from the field of view. When the field of view moves to different portions of the media item, the UI elements can be repositioned to maintain accessibility while minimizing obstruction of the current view.
4Area of stationary object
If the field of view is moved throughout the media item to view different portions, then the media item coverage is improved, but the user interface alignment becomes complex
Solution Approach 1:
The system introduces a coordinate transformation intermediary that automatically manages the alignment between the field of view and user interface elements. This intermediary layer handles the complex calculations of positioning and alignment, shielding users from the underlying complexity while enabling seamless panning and zooming.
Solution Approach 2:
The field of view and user interface elements are merged into a unified coordinate system that moves together. This ensures that UI elements remain properly aligned with the media item content regardless of field of view position, simplifying the alignment management.

AI summary
A non-transitory computer-readable medium includes instructions stored thereon for causing a display device to display a field of view of a media item and a user interface over the media item. The field of view defines a reference point and the user interface defines a perimeter. The medium also includes instructions for processing input data for controlling relative movement of one or more of the field of view, the media item, and the user interface. In addition, the medium includes instructions for causing the display device, responsive to the input data, to move the user interface relative to the field of view and the media item, provided that the reference point is within the perimeter. The medium also includes instructions for causing the display device, responsive to the input data, to move the field of view relative to the media item, provided that the reference point is outside the perimeter.
