Voice-Command Content Retrieval for Limited-Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack efficient methods for user-specific content retrieval and management using voice commands, particularly in devices with limited display capabilities, and do not effectively handle dynamic updates or user preferences.
Innovation Solution
A remote system processes voice commands to identify user topics, stores them in a database, and proactively searches for relevant content, providing it through audio or visual output based on user requests, with mechanisms for adding, removing, and managing topics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice commands are used for content retrieval in devices with limited display capabilities, then ease of operation is improved, but information delivery completeness deteriorates
Solution Approach 1:
The system segments content delivery into multiple channels: audio output for primary information delivery and display output for supplementary visual information. This allows voice commands to remain the primary interaction method for devices with limited displays while still providing comprehensive content through combined audio-visual delivery.
Solution Approach 2:
The system is designed to function universally across different device types by adapting its output delivery mechanism. It can deliver content through audio alone, display alone, or both simultaneously, making it suitable for smartphones, tablets, smart speakers, and other devices with varying display capabilities.
2Adaptability or versatility
If the system proactively searches for and stores content related to user topics, then adaptability to user preferences is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by proactively searching for, retrieving, and storing content related to user topics before the user explicitly requests it. When a user mentions a topic, the system automatically searches for related content, stores it in a database, and makes it readily available for future retrieval, thereby adapting to user preferences in advance.
Solution Approach 2:
The system provides self-service functionality by autonomously managing the content lifecycle. It automatically searches for content, stores it in the database, retrieves it when needed, and deletes it after delivery without requiring manual user intervention for each step, thereby reducing the operational burden on users.
3Measurement precision
If the system manages dynamic topic updates and content lifecycle, then user-specific content retrieval accuracy is improved, but system complexity increases
Solution Approach 1:
The system implements feedback mechanisms by monitoring user interactions with delivered content and using this information to refine future content retrieval. When users request additional content or indicate interest in specific topics, the system adjusts its search and retrieval strategies to improve accuracy for subsequent content delivery.
Solution Approach 2:
The system dynamically manages the content lifecycle by continuously updating the database with new content, removing outdated content, and adapting retrieval strategies based on current user needs. Topics and their associated content are maintained in a dynamic state, allowing the system to respond to changing user preferences and information requirements.
Data Source
AI summary
This disclosure describes, in part, techniques for identifying user-specific content items and/or time-based content items, as well as techniques for providing the content items to the user. For instance, a remote system may receive first audio data from an electronic device, where the first audio data represents a request to identify content related to a topic. The remote system can then store the topic in a database and use the topic to identify the content. Later, the remote system can then receive second audio data from the electronic device, where the second audio data represents a request for the content. The remote system can then send third audio data to the electronic device that represents at least a portion of the content.
