Solution Overview

Problem

Conventional virtual key input devices on information communication terminals lack the ability to utilize their background space effectively for user customization and business purposes, failing to provide an interactive UX-based business model.

Innovation Solution

A method and system that allows users to select, design, and create personalized background images for virtual key input devices, combining transparent skin input units with background skins, enabling the display of various business contents such as advertisements and E-learning materials, and allowing users to control the use environment for personal or business purposes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a virtual keypad is provided in software occupying a large display space, then the device provides diversity of tools and intuitive UI, but the background space is not utilized in a business way

Engineering Contradiction:

Improvevirtual keypad functionalityVSAvoidunused display space

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent applies color and transparency changes to the virtual keypad background by implementing a transparent background design that allows underlying content to be visible. The controller adjusts the transparency level of the virtual keypad background, enabling it to transition between opaque and transparent states, thereby utilizing the display space for both input functionality and background content display simultaneously.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent implements multi-functionality by making the virtual keypad background serve dual purposes: maintaining input device functionality while simultaneously displaying background images, advertisements, or other content. The transparent background allows the same display area to fulfill both the input interface role and the content display role, maximizing the utility of the limited screen space.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of manufacture

If conventional skin modification techniques are used, then skin data can be stored in external memory, but the technique does not provide a business mode based on UX and is not related to virtual keypad

Engineering Contradiction:

Improveskin data storageVSAvoidbusiness model applicability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamics by making the virtual keypad background adaptable and changeable through user selection and controller adjustment. The background can dynamically switch between different images, transparency levels, and business content based on user preferences and service provider configurations, transforming the static virtual keypad into a flexible interface that adapts to different business modes and user experiences.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces an intermediary controller that mediates between the virtual keypad, background images, and service providers. The controller manages the transparency settings, selects appropriate background content, and coordinates between user input and business content display, enabling the integration of business modes with the virtual keypad interface.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Area of stationary object

If the virtual keypad background is made transparent, then background content can be displayed, but the visibility of keypad boundaries may be reduced

Engineering Contradiction:

Improvebackground content visibilityVSAvoidkeypad boundary definition

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

The patent applies local quality by differentiating the transparency properties of different regions within the virtual keypad interface. The background area maintains high transparency for content visibility, while the keypad boundaries and key areas retain sufficient opacity or visual distinction to ensure proper definition and user interaction. This localized variation in transparency quality resolves the conflict between background visibility and boundary definition.

Inventive Principle:

Principle #3Local quality

AI summary

A method for providing a background image to a virtual key input device for display on an information communication terminal thereof supporting a touch user interface (TUI). The method includes receiving, via the information communication terminal, a selection of settings by a user for a virtual key input unit, generating the virtual key input unit using the selected settings, the virtual key input unit being transparent, receiving, via the information communication terminal, a selection of background contents by the user for the virtual key input unit, and generating a background skin based on the selected background contents, and combining the transparent virtual key input unit and the background skin.
