Voice Prompt Association via Time Window Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in accurately associating voice inputs with corresponding prompts due to the time required to receive and process voice inputs, often resulting in incorrect prompt identification as subsequent prompts are provided during processing.
Innovation Solution
The electronic device defines input windows or durations for each prompt, allowing association of voice inputs with specific prompts by matching characteristic times with these windows, which can overlap, ensuring accurate prompt identification based on timing and importance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If the device processes voice inputs sequentially as prompts are displayed, then power consumption is reduced and display is minimized, but the device cannot accurately determine which prompt the voice input corresponds to
Solution Approach 1:
The system pre-calculates and stores time windows for each prompt before the voice input is processed. When a voice input is detected, the system checks which pre-defined time window contains the current time, thereby determining the corresponding prompt without needing to display all prompts simultaneously or use complex real-time analysis.
2Ease of operation
If the device displays all prompts simultaneously on the display, then the user can see all options at once, but the device cannot save power and the display requires continuous power consumption
Solution Approach 1:
Instead of displaying all prompts simultaneously, the system segments the prompt presentation into sequential time windows. Each prompt is displayed during its designated time window, and the system tracks which time window is active. This allows the display to be turned off or minimized while still providing prompt information through audio or other non-display channels.
3Use of energy by stationary object
If the device uses audio prompts instead of visual display, then power consumption is reduced and accessibility is improved, but the user cannot see visual cues for prompt selection
Solution Approach 1:
The system makes the prompt presentation mechanism universal by supporting multiple output channels (audio, visual, haptic) that can function independently. The same time window mechanism works for all channels, allowing audio prompts to be used without visual display while maintaining the ability to provide visual feedback when needed. This multi-functional approach ensures accessibility for users with visual impairments while preserving power-saving benefits.

AI summary
This is directed to processing voice inputs received by an electronic device while prompts are provided. In particular, this is directed to providing a sequence of prompts to a user (e.g., voice over prompts) while monitoring for a voice input. When the voice input is received, a characteristic time stamp can be identified for the voice input, and can be compared to periods or windows associated with each of the provided prompts. The electronic device can then determine that the prompt corresponding to a window that includes the characteristic time stamp was the prompt to which the user wished to apply the voice input. The device can process the voice input to extract a user instruction, and apply the instruction to the identified prompt (e.g., and perform an operation associated with the prompt).
