Wearable Virtual-Space Display Scaling for Intuitive Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices struggle to efficiently manage and switch between multiple virtual spaces, providing an intuitive and energy-efficient user experience for augmented and virtual reality applications.
Innovation Solution
A wearable device with a display that sizes and distances visual objects representing different virtual spaces based on the number of applications and entries, allowing selective display and interaction with these spaces using input methods, and conditionally activating hardware components for power efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple virtual spaces are displayed simultaneously with equal visual prominence, then users can access multiple virtual spaces, but the display becomes cluttered and user interface complexity increases
Solution Approach 1:
The patent applies asymmetry by displaying visual objects of different sizes to represent different virtual spaces. The first visual object is displayed at a first size while the second visual object is displayed at a second size that is different from the first size, creating an asymmetric display hierarchy that reduces clutter while maintaining accessibility to multiple virtual spaces.
Solution Approach 2:
The patent applies local quality by giving different visual characteristics to different visual objects based on their corresponding virtual spaces. Each visual object has distinct size properties and can be positioned at different distances, allowing users to differentiate between virtual spaces through localized visual variations rather than uniform display elements.
2Adaptability or versatility
If all hardware components remain active to support multiple virtual spaces, then functionality is maintained, but power consumption increases
Solution Approach 1:
The patent applies periodic action by selectively activating hardware components based on user interaction patterns. The processor identifies when a second virtual space is selected and activates relevant hardware components at that period, rather than keeping all components continuously active, thereby reducing overall power consumption while maintaining functionality.
Solution Approach 2:
The patent applies extraction by isolating and activating only the specific hardware components needed for the currently selected virtual space. When the second virtual space is selected, the system extracts and activates the subset of hardware components required for that space, leaving other components inactive to conserve energy.
3Ease of operation
If visual objects are displayed at uniform size and distance, then display simplicity is maintained, but user ability to distinguish and prioritize virtual spaces decreases
Solution Approach 1:
The patent applies asymmetry by displaying visual objects at different sizes and distances to enhance user ability to distinguish and prioritize virtual spaces. The first visual object is displayed at a first size and the second visual object at a second size, with the first visual object positioned at a first distance and the second at a second distance, creating visual hierarchy that improves distinguishability.

AI summary
A processor of a wearable device may be configured to cause the wearable device to: display a first visual object corresponding to a first virtual space using a first size based on the number of applications linked to the first virtual space and a first distance related to the number of times of entering the first virtual space; display a second visual object corresponding to a second virtual space using a second size based on the number of applications linked to the second virtual space and a second distance related to the number of times of entering the second virtual space; and in response to an input of selecting one of the first visual object and the second visual object, display at least a part of a virtual space corresponding to the visual object selected by the input.
