Solution Overview

Problem

The increasing size of touchscreens on mobile terminals makes it inconvenient for users to manipulate them with one hand, as certain regions become difficult to touch, leading to a need for a user-friendly screen interface that facilitates easier access to functions.

Innovation Solution

A mobile terminal with a touchscreen that outputs a movable button pad with function buttons, which can be shifted to a user-desired location, allowing for easier activation of functions, particularly designed to address the accessibility issues on large-screen devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the touchscreen size is increased to provide a wider view, then the display area is improved, but the ease of operation deteriorates due to difficult access to certain regions

Engineering Contradiction:
Improvetouchscreen display areaVSAvoidaccessibility to touchscreen regions
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent merges multiple function buttons that are distributed across different regions of the large touchscreen into a single consolidated movable button pad. This allows all essential functions to be accessed from one location, resolving the contradiction by maintaining large display area while improving operational accessibility through spatial consolidation of controls.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The button pad is designed to be movable rather than fixed, allowing it to be repositioned to different locations on the touchscreen based on user needs. This dynamic characteristic enables the interface to adapt to different usage scenarios, maintaining ease of operation despite the large static touchscreen area.

Inventive Principle:
Principle #15Dynamics

2Area of stationary object

If function buttons are distributed over a large area to utilize the wide screen, then the display capability is improved, but the ease of operation deteriorates due to difficulty in reaching distant buttons

Engineering Contradiction:
Improvescreen utilization areaVSAvoidbutton accessibility
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

Multiple function buttons that would traditionally be distributed across the large screen area are merged into a single movable button pad component. This consolidation allows full utilization of the wide screen for content display while集中izing all control functions in one accessible location, thereby improving ease of operation without sacrificing display capabilities.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A mobile terminal and controlling method thereof are disclosed, which facilitates a terminal to be used in further consideration of user's convenience. The present invention includes a touchscreen and a controller, if a 1st touch gesture is received through the touchscreen, outputting a movable button pad including at least one 1st touch button to the touchscreen in response to the received 1st touch gesture, the controller, if a prescribed one of the at least one 1st touch button is selected, enabling a prescribed function corresponding to the prescribed 1st touch button. Accordingly, in controlling a touchscreen having a relatively large size, the present invention can provide a touch screen control environment for enhancing user's convenience.
