Visual Character Theme Input for Mobile Station Key Sequences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile stations lack the ability to allow users to customize font size and color for characters during input, resulting in a monotonous display experience.
Innovation Solution
A character input method that allows users to select a visual character theme, adding visual effects such as different backgrounds, fonts, and animations to characters, using a mobile station with a memory for storing themes, a key input unit, controller, and display unit to implement these effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mobile stations use fixed font size and color for character display, then device complexity is reduced and ease of manufacture is improved, but user customization capability and visual appeal deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-defining multiple visual character themes in the system memory before user input. Each theme contains predetermined font types, sizes, and color schemes. When a user selects a theme, the system immediately applies the pre-configured display parameters, avoiding the need for real-time customization calculations and reducing computational complexity during character input.
Solution Approach 2:
The patent implements parameter changes by allowing users to select from predefined sets of display parameters (font type, size, color) organized as visual themes. Instead of enabling continuous adjustment of each parameter independently, the system changes parameters in discrete, pre-configured combinations, thereby providing customization capability while maintaining manageable system complexity.
2Ease of operation
If mobile stations display monotonous key-input data with assigned font shape and size, then ease of operation is maintained and interface simplicity is preserved, but user engagement and visual interest deteriorate
Solution Approach 1:
The patent applies segmentation by dividing the display system into distinct visual theme modules, each containing a specific combination of font type, size, and color parameters. Users can select from discrete theme segments rather than adjusting individual parameters, maintaining interface simplicity while providing visual variety through theme switching.
Solution Approach 2:
The patent implements universality by creating visual themes that can be applied across different input contexts (dialing, messaging, etc.). A single theme selection provides universal customization for all character displays, eliminating the need for separate settings in different applications while enhancing visual engagement.
3Adaptability or versatility
If mobile stations use single unicolor background image, then device complexity is minimized and manufacturing is simplified, but visual appeal and user personalization capability deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-configuring coordinated background images and foreground character styles as integrated visual themes. Each theme includes a specific background image paired with matching font characteristics, allowing users to personalize display appearance without the system needing to handle background and character settings separately, thus managing complexity.

AI summary
Disclosed is a apparatus and a method for displaying various character effects on a character input screen of a mobile station using a differentiated graphic element according to a key input signal. In the method a visual character theme set by a user is displayed in a character input mode, and a character input effect corresponding to the visual character theme is shown according to a key input signal. Accordingly, since the mobile station can show a visual character input effect in every key input sequence by allowing the user to select a desired visual character theme in advance, an entertaining effect is added to a user interface of the mobile station.
