Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional voice assist technologies on mobile devices struggle to effectively broadcast content information from non-focusable elements on webpages, leading to missed information during voice broadcast operations.

Innovation Solution

A voice broadcast method and apparatus that identifies non-focusable nodes with text information and no subnodes, determines their text length, and performs node reconstruction through merging or segmentation based on content size to ensure complete voice broadcast, using a voice broadcast instruction to search for target nodes on a webpage interface and broadcast their text content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If directional buttons are used to guide focusable elements for voice broadcast, then the voice broadcast function can be supported on button mobile phones, but content information of non-focusable elements is missed

Engineering Contradiction:

Improvevoice broadcast function supportVSAvoidcontent information of non-focusable elements

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent segments the webpage content into focusable elements and non-focusable elements, then applies different handling strategies. For non-focusable elements, it extracts text content directly without requiring focus, thereby preventing information loss while maintaining compatibility with directional button guidance for focusable elements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a universal voice broadcast mechanism that works for both focusable and non-focusable elements. The system can handle different types of elements through a unified interface, allowing the voice broadcast function to cover all content types on the webpage rather than being limited to only focusable elements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Loss of information

If all text content on webpage is broadcasted sequentially, then complete information is provided, but navigation efficiency decreases for visually impaired users

Engineering Contradiction:

Improvecompleteness of content informationVSAvoidnavigation efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

Instead of broadcasting all text content uniformly, the patent applies partial action by selectively broadcasting only relevant text content from non-focusable elements. It determines whether to broadcast based on element characteristics and user context, providing sufficient information without excessive detail that would slow down navigation.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The patent applies different quality levels of information delivery to different parts of the webpage content. Focusable elements receive standard voice broadcast treatment, while non-focusable elements receive selective text extraction based on their relevance and type, optimizing the information density for each local region of the webpage.

Inventive Principle:

Principle #3Local quality

AI summary

A voice broadcast method includes: generating a voice broadcast instruction when a voice broadcast operation is received; according to the voice broadcast instruction, starting from a current focus node, detecting nodes from a current web page interface, and when a target node is determined, broadcasting text content of the target node, wherein the target node is a node with text information, has no sub-nodes and does not respond to an operation event.
