Touch Screen Lock State Contact Group Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable electronic devices with touch screens face issues of accidental function activation due to their compact size, leading to a dull user interface in the lock state, which does not enhance user experience or convenience.
Innovation Solution
The method involves displaying contact groups on the screen while in a user-interface lock state, allowing users to select and interact with contact images through touch inputs, enabling the activation of specific functions by moving these images into a designated ring, thereby enhancing user interaction and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a touch screen technique is used to integrate a keyboard with a screen to save cost and area, then the electronic device becomes more compact and cost-effective, but the user may inadvertently touch screen keys to execute specific functions by accident
Solution Approach 1:
The system performs preliminary action by automatically activating the user-interface lock state after detecting a predetermined period of non-operation, or by manually setting the lock state when the user does not need to operate the device. This prevents accidental function activation before it can occur.
Solution Approach 2:
The touch screen dynamically switches between locked and unlocked states based on user interaction. When locked, the screen prevents input functions; when unlocked, it allows normal operation. This dynamic state change resolves the contradiction between compact design and accidental activation prevention.
2Device complexity
If a single picture file is used as the background in the user-interface lock state, then the implementation is simple, but the background looks dull and the usage fun is not effectively improved
Solution Approach 1:
The patent merges multiple contact images into a single background composition during the lock state. Instead of displaying individual contact images separately, it combines them into one cohesive background image, maintaining implementation simplicity while enhancing visual appeal and user experience.
Solution Approach 2:
The background image serves multiple functions: it maintains the simple single-image implementation structure while simultaneously displaying multiple contact images, providing both aesthetic appeal and functional information access during the lock state.

AI summary
A method of providing a background of an electronic device, and an electronic device and a computer program product using the method are provided. The method includes displaying one or more contact groups for selection while the electronic device is in a user-interface unlock state, detecting a touch input applied to a contact group of the one or more contact groups on or near the touch screen, and in response to detecting the touch input applied to the contact group on or near the touch screen, selecting the contact group to display a contact image of a contact in the contact group on the touch screen while the electronic device is in a user-interface lock state.
