Stroke Input Menu Navigation for Voice Assist Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In accessibility modes of electronic devices, users face inefficiencies when navigating through menu icons, requiring extensive time and effort to access desired functions, especially when using voice assist functions.
Innovation Solution
An electronic device with sensors, a touchscreen display, and a processor that outputs menu icons with sequence numbers, senses stroke inputs, identifies movement directions, and specifies menu icons based on these inputs, allowing for rapid execution of functions through voice guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a voice assist function sequentially moves to the next region to provide information, then information is provided on each region, but a lot of time and effort is repeatedly consumed to access a desired region from an arbitrary region
Solution Approach 1:
The patent segments the navigation process by dividing the menu icon grid into multiple regions and allowing users to directly specify target regions or icons within those regions, rather than sequentially moving through each region. This segmentation enables direct access to specific areas of the menu, significantly reducing navigation time and effort.
2Ease of operation
If all menu icons are passed sequentially to specify the last menu icon, then the desired menu icon is eventually accessed, but extensive time and effort are consumed
Solution Approach 1:
The patent implements preliminary action by allowing users to pre-specify target regions or menu icons before actual access is needed. The system divides the menu into regions and enables direct specification of target positions within those regions, so that when a user wants to access a specific menu icon, they can directly navigate to its region and specify the icon, rather than sequentially passing through all previous icons.
3Measurement precision
If a stroke input system divides a screen into multiple regions, then region specification becomes possible, but the system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the screen into multiple regions for stroke input processing. Each region can be independently identified and processed, allowing the system to determine which region a stroke input targets and handle the input accordingly. This segmentation improves measurement precision for region specification while managing system complexity through modular region handling.
