Solution Overview

Problem

Existing Augmented Reality (AR) services on mobile devices require users to manually select an application icon from a start screen, which is inconvenient and does not allow for intuitive switching between AR and other screens.

Innovation Solution

A mobile communication terminal with a camera and touch screen that detects predetermined events, such as tilting, to automatically change from a prior screen to an AR service screen by capturing and rendering images with augmented information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually select application icons from a start screen to access AR services, then the system can provide comprehensive service options, but user convenience and operation speed deteriorate

Engineering Contradiction:
ImproveUser convenienceVSAvoidTime to access AR service
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-configuring AR service activation conditions (such as detecting specific gestures, tilts, or environmental triggers) before the user needs to access the service. When the condition is met, the AR service automatically activates without requiring the user to manually search for or select the application icon, thereby reducing access time and improving convenience.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The AR service system implements self-service by automatically detecting user intentions through sensors (camera, gyroscope, accelerometer) and autonomously activating the service based on predefined conditions. This eliminates the need for users to manually navigate the start screen and select icons, as the system serves itself by interpreting user context and initiating the appropriate service automatically.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If the system requires manual selection of AR service from start screen, then application organization is maintained, but screen switching intuitiveness deteriorates

Engineering Contradiction:
ImproveScreen switching intuitivenessVSAvoidScreen transition mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system replaces the mechanical interaction of manually tapping icons on a start screen with sensor-based detection mechanisms (camera vision, gyroscope tilt detection, accelerometer motion sensing). This substitution enables more intuitive screen switching by interpreting natural user actions (like tilting the device or pointing with a finger) as triggers for service activation, making the transition feel more natural and less arbitrary.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The screen switching mechanism becomes dynamic by responding to real-time sensor input rather than static icon selection. The system continuously monitors sensor data (device orientation, motion, environmental features) and dynamically transitions to the AR service screen when appropriate conditions are met, creating a flexible and adaptive user experience that adapts to user behavior patterns.

Inventive Principle:
Principle #15Dynamics

AI summary

A method of changing into a screen of an Augmented Reality (AR) service in a mobile communication terminal including a camera is provided. The method of changing into a screen of an AR service in a mobile communication terminal includes displaying a prior screen different from an AR service screen, detecting a predetermined event to change display of the prior screen to the AR service screen, driving the camera if the predetermined event has been detected, capturing an image using the camera, and displaying the AR service screen rendered based on the image captured by the camera.
