Solution Overview

Problem

Users face difficulty in efficiently utilizing the various functions provided by electronic devices, particularly in photographing, due to complex user interfaces and the need for intuitive communication methods.

Innovation Solution

An electronic device and method that recognize an object corresponding to a hand gesture in a preview image and display a photographing screen with the target object, allowing for intuitive selection and locking of objects for photographing, with notifications and vibrations guiding the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional user interface methods are used for photographing, then the device can provide multiple functions, but users find it difficult to efficiently use all the functions

Engineering Contradiction:

Improveease of photographing operationVSAvoidcomplexity of user interface

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically recognizes objects in the preview image and locks them as target objects without requiring manual selection by the user. The device serves itself by autonomously identifying and selecting photographing targets based on object detection algorithms, eliminating the need for complex manual interface operations.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical selection operations with automated computer vision and object recognition systems. Instead of requiring users to manually tap or select objects on the screen, the system uses image processing algorithms to automatically identify and lock target objects, substituting mechanical user interactions with automated digital recognition.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If manual object selection is required, then the user can control the photographing target, but the photographing process becomes time-consuming

Engineering Contradiction:

Improvephotographing efficiencyVSAvoidtime for object selection

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary object recognition and locking actions automatically before the user needs to photograph. The object detection and target locking occur in advance based on the preview image, so when the user initiates photographing, the target is already selected and ready, eliminating the time-consuming manual selection process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides real-time feedback by displaying the recognized target object in the preview image and locking it automatically. This feedback mechanism allows the user to see immediately which object has been selected and confirmed, enabling rapid confirmation or adjustment without time-consuming manual selection procedures.

Inventive Principle:

Principle #23Feedback
