Personalized Voice Prompting for Camera Subject Age Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intelligent terminals lack personalized prompting for photographing, as they typically emit a single prompt tone regardless of the subject's age or completeness in the framing interface, failing to cater to diverse user needs.
Innovation Solution
A method and apparatus that determine the age range of the photographed subject and adjust voice prompt messages based on pre-set age ranges and correspondence relationships, with additional considerations for subject completeness and gender, allowing for tailored prompting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single prompt tone is emitted for all users, then the device complexity is reduced and ease of operation is improved, but the adaptability to different user needs deteriorates
Solution Approach 1:
The patent segments the user base into different age groups (children, teenagers, adults, elderly) and provides different voice prompt messages for each segment. The system divides the prompting function into age-specific sub-functions, allowing tailored communication without requiring complete system redesign for each user type.
Solution Approach 2:
The patent applies local quality by making the voice prompt messages age-specific rather than uniform. Different age groups receive prompts with appropriate tone, content, and style (e.g., gentle prompts for elderly, enthusiastic prompts for children), optimizing the user experience for each local segment while maintaining a unified system architecture.
2Adaptability or versatility
If age-specific voice prompt messages are implemented, then the adaptability to different user needs is improved, but the device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-categorizing users into age groups and pre-defining appropriate voice prompt messages for each category. The system prepares the prompting strategy in advance based on detected age, rather than generating complex real-time decisions during operation, thus reducing runtime complexity.
Solution Approach 2:
The patent changes the parameter of voice prompt characteristics (tone, content, style) based on the age parameter of the user. By making the prompt messages dynamic and adjustable according to age, the system achieves high adaptability without requiring complex structural changes, merely parameter adjustments within an existing framework.
3Measurement precision
If comprehensive user characteristics are analyzed for prompting, then the measurement precision of user needs is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent extracts only the most critical user characteristic (age) for the prompting function, rather than analyzing all possible user attributes. By focusing on age as the key determining factor and ignoring less relevant characteristics, the system achieves sufficient measurement precision for its purpose while keeping detection complexity low.

AI summary
The present disclosure relates to a prompting method and apparatus for photographing. The method includes: obtaining a target state characteristic of a target photographed subject in a current framing interface of a terminal; and determining a target voice prompt message corresponding to the target state characteristic. With this method, it is possible to obtain the target state characteristic of the target photographed subject in the current framing interface of the terminal, and thus determine the target voice prompt message corresponding to the target state characteristic, thereby prompting a user with the target voice prompt message. Different target photographed subjects and target state characteristics may correspond to different target voice prompt messages, instead of prompting all the users with the same prompt message. Thus, different prompting needs of different users can be satisfied through targeted output of the target voice prompt message.
