Head-Mountable Display Gesture Navigation and Cropping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted displays (HMDs) lack intuitive navigation and editing capabilities, particularly in three-dimensional spaces, making it difficult for users to efficiently interact with and manipulate objects within a Z-axis oriented display (ZAOD) environment.
Innovation Solution
A head-mountable device (HMD) configured with a hand-movement input device that receives head-movement and hand-movement data to pan and zoom objects on a display, allowing users to activate a cropping mode and generate a cropped image of viewable objects for further operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional navigation methods are used on HMDs, then the display can show information, but the ease of operation deteriorates due to lack of intuitive interaction in 3D space
Solution Approach 1:
The patent replaces traditional mechanical input devices (buttons, knobs, joysticks) with natural body movements (head gestures, hand gestures) to control the display. Head movements control panning and zooming, while hand gestures enable object selection and navigation in 3D space, making the interface more intuitive and easier to operate.
Solution Approach 2:
The patent extends the traditional 2D display interface to a 3D interactive environment. Users can navigate through depth (Z-axis), rotate objects in 3D space, and interact with virtual objects positioned at different distances, adding a third dimension to the user interaction model.
2Adaptability or versatility
If detailed object manipulation is enabled, then the functionality improves, but the device complexity increases due to multiple navigation and editing modes
Solution Approach 1:
The patent implements a universal gesture-based control system where a single hand gesture input device can perform multiple functions including panning, zooming, object selection, navigation, and editing operations. This multi-functional approach reduces the need for separate controls for each function while maintaining high versatility.
Solution Approach 2:
The system dynamically adapts its behavior based on the current view and user actions. The interface automatically adjusts navigation options, display parameters, and interaction modes according to the user's position in 3D space and the object being viewed, providing appropriate functionality without requiring manual mode switching.
3Adaptability or versatility
If cropping mode is added for image manipulation, then the versatility improves, but the ease of operation may worsen due to additional interface requirements
Solution Approach 1:
The patent merges the cropping function with the existing gesture-based navigation system. Users perform cropping operations using the same hand gestures already familiar from navigation, combining multiple functions (navigation and cropping) into a unified interaction paradigm rather than adding separate controls.
Solution Approach 2:
The system provides automated cropping based on user gestures. When users perform zooming or panning gestures, the system automatically identifies the region of interest and prepares cropped images, reducing the need for manual cropping operations and simplifying the user interface.
Data Source
AI summary
Methods, apparatus, and computer-readable media are described herein related to displaying and cropping viewable objects. A viewable object can be displayed on a display of a head-mountable device (HMD) configured with a hand-movement input device. The HMD can receive both head-movement data corresponding to head movements and hand-movement data from the hand-movement input device. The viewable object can be panned on the display based on the head-movement data. The viewable object can be zoomed on the display based on the hand-movement data. The HMD can receive an indication that navigation of the viewable object is complete. The HMD can determine whether a cropping mode is activated. After determining that the cropping mode is activated, the HMD can generate a cropped image of the viewable object on the display when navigation is complete.
