Display Apparatus Automatic Mode Switching via Pointer Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses require manual user intervention to switch operation modes, which may not accurately reflect the user's intention, especially when interacting with image objects on the screen.
Innovation Solution
A display apparatus that automatically switches operation modes based on the detected position of a pointer, using a detecting section to determine if the pointer is within a predetermined range of an image object, and adjusts the mode accordingly, with features like line drawing and notification to enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual menu operation is used to switch operation modes, then the user can control the switching process, but the user intention may not be accurately reflected and the operation becomes complex
Solution Approach 1:
The display apparatus automatically determines whether to switch operation modes by detecting pointer position and determining whether an image object is present, eliminating the need for manual menu selection. The system serves itself by making intelligent decisions based on detected conditions, thereby simplifying operation while accurately reflecting user intention through contextual awareness.
Solution Approach 2:
The system continuously monitors pointer position and image object presence, using this feedback to automatically determine mode switching. This closed-loop feedback mechanism ensures that mode switching accurately reflects user intention based on real-time contextual information, resolving the contradiction between simple operation and accurate intention recognition.
2Reliability
If automatic mode switching is implemented, then user intention is better reflected, but the system complexity increases
Solution Approach 1:
The patent extracts the mode switching decision logic from manual user operation and embeds it in the display apparatus itself. By taking out the complex decision-making process from the user and implementing it within the system, the apparatus achieves accurate intention recognition while managing complexity internally through structured detection and determination processes.
3Ease of operation
If line drawing is performed during pointer movement, then user interaction is enhanced, but wait time increases when determining mode switching
Solution Approach 1:
The display apparatus performs preliminary line drawing during pointer movement before the mode switching determination is complete. By starting the drawing action in advance and continuing it while waiting for the determination result, the system enhances user interaction quality without causing noticeable delay, as the drawing proceeds concurrently with the determination process.

AI summary
A display apparatus includes a display section configured to display, on a display surface, a screen of an application program running on an information processing apparatus, a detecting section configured to detect the position of a pointer, a receiving section configured to receive a determination result concerning whether the position is present within a predetermined range including an image object, a drawing section configured to draw, when an operation mode is a first mode, a line corresponding to a track of the position, a second transmitting section configured to transmit, when the operation mode is a second mode, the information indicating the position to the information processing apparatus, and a switching section configured to switch, when the operation mode is the first mode, the operation mode to the second mode when the receiving section receives the determination result indicating that the position is within the predetermined range.
