Mobile Terminal Rear Input Unit for Layered Application Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals require cumbersome operations to access and control applications on lower layers while maintaining functionality on upper layers, leading to inefficiencies in multitasking due to the need for frequent layer switching and complex command inputs.
Innovation Solution
A mobile terminal design featuring a rear-surface user input unit that allows intuitive control of applications on lower layers by integrating a rear input unit with the display unit, enabling flicking, rotating, and touch inputs to manage multiple layers without changing the upper layer's display state, allowing seamless access and control of lower layer applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user switches to access an application on the lower layer, then the user can control the lower layer application, but the upper layer application must be deactivated and the layer switching becomes complex
Solution Approach 1:
The input device is segmented into two distinct parts: a front surface input unit for controlling the upper layer application and a rear surface input unit for controlling the lower layer application. This segmentation allows independent control of different layers without requiring full layer switching, thereby simplifying the operation while maintaining access to lower layer applications.
2Ease of operation
If the user switches layers to control lower layer application, then the lower layer application can be controlled, but the operation time and steps increase
Solution Approach 1:
The system prepares both upper and lower layer applications to run simultaneously in advance. The rear surface input unit is pre-configured to send control commands directly to the lower layer application without requiring layer switching. This preliminary preparation eliminates the time-consuming layer switching process while enabling direct control of the lower layer application.
3Adaptability or versatility
If multiple applications are executed on one screen, then multitasking is enabled, but the control of lower layer applications becomes difficult
Solution Approach 1:
The control interface is extended from a two-dimensional screen to a three-dimensional structure by adding a rear surface input unit. This dimensional extension allows the user to access and control lower layer applications through a spatially distinct input path, making multitasking more intuitive and easier to operate while maintaining simultaneous execution of multiple applications.

AI summary
A mobile terminal including a display unit arranged on the front surface so multiple pieces of visual information corresponding to multiple layers, respectively; and a front-surface input unit so a control command is input into the front-surface input unit and a rear input unit arranged on the rear surface so the control command is input into the rear input unit; and a controller to apply a function corresponding to an input to first visual information displayed on a first layer, and activate a second layer arranged under the first layer while maintaining a state in which the first visual information is displayed on the first layer in response to input to the rear input unit.
