Display Device Indicator Routing for Error Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with multiple input indicators face complications in preventing operation errors due to diversification of input functions, leading to uncertainty in user operations.
Innovation Solution
A display device that includes an acquisition unit, detection unit, generation unit, display unit, designation unit, and control unit to differentiate between two types of indicators, allowing for the generation and display of images based on their positions, enabling the user to distinguish between drawing and other operations, and switch the supply destination of information to prevent unintended inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple indicators with different functions are used simultaneously, then input function diversity is improved, but operation reliability deteriorates due to complicated operation contents and increased operation errors
Solution Approach 1:
The patent segments the functionality of multiple indicators by assigning dedicated processing paths for each indicator type. The detection unit identifies whether the indicator is a first or second indicator, and the control unit routes the indicator information to different processing destinations based on the indicator type, thereby segmenting the complex multi-indicator operations into manageable, error-free pathways
Solution Approach 2:
The patent introduces an intermediary detection unit that acts as a mediator between the multiple indicators and the control unit. This detection unit specifies the position and type of each indicator, serving as an intermediate processing layer that prevents direct confusion between different indicator functions and ensures reliable routing of indicator information
2Adaptability or versatility
If multiple indicators with different functions are used simultaneously, then input function diversity is improved, but device complexity increases due to need for differentiated processing
Solution Approach 1:
The control unit is designed with universal functionality to handle both first and second indicators through a unified architecture. Rather than creating separate dedicated processing units for each indicator type, the control unit can adaptively process different indicator types by receiving type identification information from the detection unit and routing accordingly, thereby reducing overall system complexity while maintaining input function diversity
3Adaptability or versatility
If information from second indicator is supplied to generation unit for attribute change, then input function diversity is improved, but ease of operation deteriorates due to potential confusion with first indicator operations
Solution Approach 1:
The patent applies local quality by providing indicator-specific processing pathways within the unified control unit. When a second indicator is detected, the control unit specifically routes its information to the generation unit for attribute changes, while first indicator information follows a different path. This localized processing approach ensures that each indicator type receives appropriate handling without interfering with others, maintaining operational simplicity despite functional diversity

AI summary
A display device includes: an acquisition unit which acquires a first image from an image supply device; a detection unit which specifies a position of the indicator and whether the indicator is a first indicator or a second indicator; a generation unit which generates a second image based on the specified position and generates a third image by superimposing the second image on the first image; a display unit which displays the third image; a designation unit which designates either the generation unit or the image supply device as a supply destination of information indicating a position of the second indicator; and a control unit which supplies the information indicating the position of the indicator to the generation unit if the detected indicator is the first indicator, and supplies the information indicating the position of the indicator to the supply destination if the detected indicator is the second indicator.
