Vehicle Voice Assistant Task Handling for Multi-Action Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice assistant systems require multiple individual requests and communications for performing a series of actions, which is inconvenient and inefficient, particularly when interacting with vehicle functions.
Innovation Solution
A control system that integrates a task handler to perform multiple actions simultaneously, reducing the need for separate invocations and communications, allowing combined responses for user requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individual requests are used to perform a series of actions, then each action can be executed independently, but the communication overhead and user convenience deteriorate
Solution Approach 1:
The patent combines multiple individual action requests into a single batch request that can be processed together. The system allows users to submit multiple actions in one communication cycle, and the server processes them as a batch, returning multiple results in a single response. This merging approach reduces the number of communication rounds while maintaining the reliability of individual action execution.
Solution Approach 2:
The system performs preliminary processing by pre-defining action templates and parameters that can be reused across multiple actions. When a user submits a batch request, the system has already prepared the processing framework, allowing for faster execution of multiple actions compared to handling them individually. This preliminary setup reduces the communication and processing overhead.
2Ease of operation
If multiple individual requests are used to perform a series of actions, then each action can be processed separately, but the system complexity and communication overhead increase
Solution Approach 1:
The patent implements a universal batch processing interface that can handle multiple different types of actions through a single request structure. The system defines a standardized action template that can accommodate various action types (such as media playback, device control, information queries) within the same communication framework. This multi-functional approach simplifies user operation while managing system complexity through standardization.
3Productivity
If separate invocations are used for each action, then precise control over each action is achieved, but user convenience and efficiency deteriorate
Solution Approach 1:
The system merges multiple action invocations into a single batch request that users can submit at once. This combining approach allows users to execute multiple actions with a single voice command or input, significantly improving productivity and user convenience. The system processes the batch request and returns results for all actions in one response cycle.
