Display Control Device Superimposing Message Screen on Operable Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display control devices struggle to provide an intuitive user interface when messages are displayed to users, as existing methods often restrict user interactions without clear indication, leading to confusion about operable and inoperable objects during message display.
Innovation Solution
A display control device that determines the size and position of a secondary display screen based on the necessity of user interaction with objects on the primary screen, allowing the secondary screen to be superimposed on the primary screen in a manner that does not obscure operable objects, and indicates inoperable objects during message display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a message is displayed on the display screen, then the user is notified of the event, but the user interface becomes difficult to understand and operate
Solution Approach 1:
The display screen is segmented into multiple regions: a message display region for showing notifications and an object display region for showing operable objects. This segmentation allows the message and objects to be displayed separately, preventing the message from obscuring the objects and maintaining ease of operation while still delivering notifications effectively.
Solution Approach 2:
Different regions of the display screen are assigned different functions with distinct visual characteristics. The message display region has specific display properties (such as background color, text style) that differ from the object display region, allowing users to easily distinguish between notifications and operable elements, thus improving interface understandability.
2Illumination intensity
If the message display screen is made large to ensure visibility, then the message is more noticeable, but it obscures the operable objects on the first display screen
Solution Approach 1:
The display area is divided into distinct segments: a message display region and an object display region. The message can be displayed prominently in its designated region without necessarily obscuring the objects, as they occupy separate spatial areas on the screen.
Solution Approach 2:
Instead of competing for the same two-dimensional space, the message and objects are arranged in different spatial regions or layers on the display screen, allowing both to be visible and accessible simultaneously through spatial differentiation.
3Ease of operation
If the message display screen is made small to preserve object visibility, then the objects remain accessible, but the message becomes less noticeable
Solution Approach 1:
By segmenting the display into dedicated message and object regions, the message can be displayed at an optimal size in its region without being constrained by the need to keep objects fully visible, as the objects occupy their own separate region.

AI summary
A display control device includes a display that displays a first display screen including an object that is operable, an operation inputter that receives an operation on the object, and one or more controllers, wherein when detecting an event in a state where the first display screen is displayed, the one or more controllers determine a size of a second display screen including a message based on the event in accordance with whether it is necessary to operate the object on the first display screen, and perform control of displaying the second display screen on the display such that the second display screen is superimposed on the first display screen.
