Solution Overview

Problem

Current portable devices lack an efficient method to dynamically change screens based on user input through continuous touch movements within text areas, such as speech bubbles, limiting interactive functionality in applications like chatting.

Innovation Solution

A portable device and method that detect continuous touch movements within text areas on the screen, recognize the selected text, and change the application screen accordingly, utilizing a processor and communication unit to transmit control commands for text recognition and screen changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional touch input methods (single tap, click) are used, then the operation is simple and easy to understand, but the interactive functionality and screen switching capability are limited

Engineering Contradiction:
Improvescreen switching capabilityVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies dynamics by transforming static touch points into dynamic continuous movement gestures. The system detects and responds to continuous touch movements (swipes, drags, flicks) rather than single static taps, enabling dynamic screen switching and text selection based on the direction and duration of the movement. This resolves the contradiction by adding versatility through movement-based interaction while maintaining ease of use through intuitive gesture recognition.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces another dimension to touch interaction by adding movement trajectory and directionality to the traditional point-based touch model. Instead of interacting with text or screens through single-point contact, users can perform continuous movements (swiping left/right/up/down, flicking) that add spatial dimensionality. This enables new interaction modes like selecting text by dragging, switching screens by flicking, or navigating menus by swiping, thereby enhancing versatility without significantly complicating the operation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If text recognition and continuous movement detection are added, then the interactive functionality is enhanced, but the device complexity increases

Engineering Contradiction:
Improveinteractive functionalityVSAvoidprocessing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by using a unified continuous movement detection mechanism to achieve multiple interaction goals: text selection, screen switching, and gesture-based commands. The same touch movement detection system serves various purposes depending on context (e.g., horizontal swipe selects text, vertical swipe changes screens, flick activates notifications). This approach enhances interactive functionality while avoiding the need for separate processing systems for each function, thereby managing device complexity effectively.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system employs self-service by automatically recognizing and executing actions based on the detected touch movement patterns without requiring additional manual input. The processor automatically identifies the type of gesture (swipe, flick, drag), determines the intended action (text selection, screen change, notification), and executes it autonomously. This reduces the need for complex user input sequences and manual configuration, enhancing functionality while keeping the processing logic streamlined and manageable.

Inventive Principle:
Principle #25Self-service
