Mobile Terminal Note Input via Overlay Display Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals lack the ability to effectively display touch trajectories corresponding to user inputs, especially when switching between screens, which hinders the usability of prompt note functions.
Innovation Solution
A mobile terminal with a control method that overlays a second layer on the screen to display touch trajectories, allowing users to input notes seamlessly without changing the primary screen display, using a controller to manage touch inputs and layer visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screen display is changed to show touch trajectories, then the note input function is improved, but the primary screen functionality and visibility deteriorate
Solution Approach 1:
The patent introduces a second layer that is superimposed on the first layer (primary screen). This layering approach allows touch trajectories to be displayed in an additional dimension without replacing or obscuring the primary screen content. The second layer can be transparent or translucent, enabling simultaneous visibility of both the primary screen display and the touch trajectory annotations, thus resolving the contradiction between improving note input and maintaining screen visibility.
Solution Approach 2:
The second layer acts as an intermediary between the user's touch input and the primary screen display. Instead of directly modifying the primary screen to show touch trajectories (which would obscure content), the patent uses this intermediate layer to carry the trajectory information. This mediator layer can be selectively activated and deactivated, allowing users to input notes while preserving the underlying screen content for reference.
2Ease of operation
If a second layer is overlaid to display touch trajectories, then the note function is enhanced, but the device complexity increases
Solution Approach 1:
The second layer is designed to serve multiple functions: it displays touch trajectories for note input, maintains transparency to show underlying content, and can be selectively activated or deactivated. This multi-functionality reduces the need for separate systems for each function, thereby managing complexity while enhancing the note-taking capability.
Solution Approach 2:
The controller automatically manages the second layer's visibility and interaction based on user input detection. When touch input is detected, the system automatically activates the second layer to display trajectories; when touch input ceases, the layer can be deactivated. This automated self-management reduces the burden on users to manually control complex layer settings, effectively managing device complexity through intelligent automation.

AI summary
A mobile terminal including a wireless communication unit configured to wirelessly communicate with at least one other terminal; a display configured to display a first screen layer corresponding to one of a back screen of the mobile terminal and an execution screen of an application installed on the mobile terminal, and to display a second screen layer corresponding to a note function of the mobile terminal; and a controller configured to control the display to selectively display the second screen layer based on an input request for requesting the second screen layer, to receive a touch input on the first or second screen layers and to execute a function corresponding to the received touch input on the first or second screen layers.
