Presentation Apparatus Mode Differentiation via Button State Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing presentation apparatuses fail to differentiate between application mode and presentation mode on the screen display, leading to user misidentification of the operation mode, especially when not all applications support annotation functions.
Innovation Solution
A presentation apparatus and method that utilize a first holding unit for parts data including type, location, and size of component parts, and a second holding unit for selection rules to change the drawing state of components in presentation mode, with a processing unit generating images to distinguish between application and presentation modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transparent window is overlaid on the application window to enable annotation, then the annotation function is added to the application, but the button appearance does not change leading to misidentification of operation mode
Solution Approach 1:
The patent applies color changes to buttons during presentation mode to indicate their inoperable state. Specifically, buttons are displayed in a grayed-out or dimmed state when the system is in presentation mode, providing visual feedback that distinguishes the current operation mode from application mode while maintaining the annotation functionality.
Solution Approach 2:
The patent introduces an intermediary layer (transparent window or overlay) that sits between the application window and the user interface elements. This intermediary layer enables annotation functionality while allowing the underlying application interface to remain visible, and it coordinates with the button state management to provide mode indication.
2Adaptability or versatility
If screen capture of application window is performed for annotation, then annotation can be performed on captured image, but button appearance remains unchanged causing user to mistakenly identify presentation mode as application mode
Solution Approach 1:
The patent uses color changes or visual state changes of buttons to indicate presentation mode. When the system enters presentation mode, buttons are visually distinguished (e.g., grayed out, dimmed, or highlighted) to communicate to the user that the system is in a different operational state where application interactions are limited.
Solution Approach 2:
The patent implements visual feedback mechanisms that provide real-time information about the current operation mode to the user. The button appearance changes serve as feedback that the system has transitioned to presentation mode, allowing users to understand the current state without confusion.
3Device complexity
If application mode and presentation mode are not differentiated on screen display, then the interface remains simple, but users cannot distinguish the current operation mode leading to erroneous operations
Solution Approach 1:
The patent employs color changes as a simple yet effective visual indicator to differentiate between operation modes. By changing the appearance of buttons or interface elements based on the current mode, the system provides clear mode indication without significantly increasing interface complexity.
Solution Approach 2:
The patent applies dynamic changes to the interface based on the current operation mode. The button appearances are dynamically adjusted according to whether the system is in application mode or presentation mode, providing intuitive visual cues that help users understand the current state and prevent erroneous operations.
Data Source
AI summary
A presentation apparatus stores parts data that includes parts data that includes type, location, and size of component parts that are displayed within a selected screen area, together with a selection rule that depicts the type of the component part that is to change a drawing state when the presentation apparatus is running in a presentation mode. When executing a presentation process, the apparatus selects a component part from the parts data, according to the selection rule, processes the selected screen area by changing an image of the selected component part, and generates the image to be used in the presentation.
