Solution Overview

Problem

Mobile terminals face errors in user input when grouping objects, such as selecting folders, due to the complexity of touch input methods, leading to inefficiencies in object organization.

Innovation Solution

A mobile terminal and control method that detect attribute information from touch inputs, allowing objects to be grouped based on the degree of touch input applied, using indicators to visually confirm grouping and enable easy reassignment to different groups through touch inputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If touch input methods are used for grouping objects, then object organization functionality is enabled, but user input errors increase due to complexity

Engineering Contradiction:
Improveobject organization functionalityVSAvoiduser input accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements visual feedback by displaying indicators on the display unit that correspond to different grouping categories. When a user applies touch input to an object, the system provides immediate visual feedback showing which category the object is being assigned to, allowing users to confirm their intended action and avoid misassignment errors.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent changes the parameter of touch input detection from simple binary touch/no-touch to detecting the degree or intensity of touch input. By measuring the magnitude of the touch (e.g., pressure level, duration, or movement distance), the system can distinguish between different grouping intentions and assign objects to appropriate categories more accurately.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple touch input methods are provided for folder selection, then grouping flexibility is improved, but operation complexity increases

Engineering Contradiction:
Improvegrouping flexibilityVSAvoidoperation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent makes the touch input detection mechanism universal by using a single unified method to handle multiple grouping scenarios. The same touch input detection mechanism can assign objects to different categories, modify existing groups, or cancel assignments, eliminating the need for separate complex procedures for each grouping operation.

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

Solution Approach 2:

The system performs self-service by automatically interpreting the user's touch input intent based on the detected degree of touch. The controller automatically determines the grouping action to be performed without requiring explicit user selection from multiple methods, reducing operational complexity while maintaining flexibility.

Inventive Principle:
Principle #25Self-service

AI summary

The present disclosure relates to a mobile terminal, and more particularly, to a mobile terminal in which a touch input is possible and a control method thereof. A mobile terminal includes a display unit and a control unit. The display unit enables a touch input thereon, and allows a plurality of objects to be displayed thereon. When a touch input for at least one of a plurality of objects is sensed, the control unit detects attribute information of the sensed touch input, and groups the touched object into a group corresponding to the detected attribute information, and displays, on the display unit, an indicator indicating that the touched object has been grouped into the group corresponding to the detected attribute information, together with the object.
