Solution Overview
Problem
Users face difficulties in quickly selecting or setting user interfaces on mobile terminals due to complex physical interfaces, and touch screens become inconvenient as they are covered by fingers or stained from frequent use.
Innovation Solution
A mobile terminal control apparatus and method using a plurality of touch sensors on the rear of the device, allowing users to select or set functions without covering the screen, with a touch recognition unit and execution unit to display and execute user interfaces based on finger touches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen is used on the front surface of the mobile terminal, then the user can select functions through GUI without physical buttons, but the screen becomes covered by fingers during operation and becomes stained from frequent touching
Solution Approach 1:
The touch sensor is extracted from the front surface and relocated to the rear surface of the mobile terminal. This allows users to operate the device by touching the rear surface while viewing the front display, eliminating the problem of fingers covering or staining the display screen.
Solution Approach 2:
The interaction surface is moved from the two-dimensional front display area to the rear surface, creating a separate input dimension. Users can touch the rear surface to control functions while the front screen remains visible and unstained.
2Ease of operation
If physical user interface elements are provided on the mobile terminal, then the user can easily select functions, but the user interface becomes complicated and difficult to quickly locate specific functions
Solution Approach 1:
Physical mechanical buttons and switches are replaced with a touch sensor system that works in conjunction with a graphical user interface displayed on the screen. This reduces the number of physical components while maintaining ease of operation through intuitive graphical selections.
3Ease of operation
If the front surface is made into a touch screen for direct interaction, then the user can control functions directly, but the user must release the device to touch the screen which is inconvenient
Solution Approach 1:
The touch functionality is extracted from the front display surface and placed on the rear surface, allowing users to maintain their gripping position and control the device without releasing or repositioning their hand.
Solution Approach 2:
The rear touch sensor acts as an intermediary input mechanism that translates rear-surface touches into front-screen control actions, enabling indirect but convenient control while maintaining a secure grip.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible control of user interfaces without covering the screen, preventing stains and allowing convenient operation by recognizing finger touches and pressure changes, optimizing user input and output processing.
Implementation Method 1
a plurality of touch sensors on a rear of the mobile terminal, a touch recognition unit recognizing a touch of a finger sensed by at least one of the plurality of touch sensors
Data Source
AI summary
A mobile terminal control apparatus and method is disclosed. The mobile terminal control apparatus includes a plurality of touch sensors formed on a rear of the mobile terminal, a touch recognition unit recognizing a touch of a finger sensed by the plurality of touch sensors and displaying a user interface on a front screen of the mobile terminal according to the recognized touch of the finger, and an execution unit recognizing a change in the touch of the finger, and executing the displayed user interface on the basis of the result of the recognition. The mobile terminal may control user interfaces of a mobile terminal without fingers overlapping a screen of the mobile terminal.
