Touchscreen Web Content Selection by Priority Levels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of information processing devices like multifunction peripherals (MFPs) often inadvertently select unintended web contents due to visual limitations, especially when using fingers instead of a mouse, leading to erroneous selections and additional work.
Innovation Solution
An information processing apparatus with a display control unit that determines the selection of web contents based on priority levels set for objects within a defined range of the pressed coordinate point, using a priority order table to ensure the intended content is selected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user operation is performed on a web content displayed on a touch panel, then the web content can be selected, but erroneous selection of unintended web content may occur due to visual limitations
Solution Approach 1:
The patent introduces an intermediary processing layer between the user's touch input and the web content selection. When a touch operation is detected, the system performs intermediary processing to determine the actual selection target by analyzing the relationship between the touched position and surrounding web content elements, rather than directly selecting the content at the exact touch coordinates. This intermediary step prevents erroneous selections by resolving ambiguities in user intent.
2Reliability
If the selection target is changed to a smaller web content located within a predetermined distance, then erroneous selection is reduced, but the complexity of the selection logic increases
Solution Approach 1:
The patent changes the parameters of the selection logic by introducing a priority level system and spatial relationship analysis. Instead of simply selecting based on proximity or size, the system evaluates multiple parameters including the touched position, positions of surrounding web content, size relationships, and priority levels. This parameter-based approach provides a systematic framework that reduces erroneous selections while maintaining manageable complexity through structured evaluation criteria.

AI summary
In order to offer better user experience, provided is an information processing apparatus including at least one memory and at least one processor which function as a display control unit that performs control to display a screen including a first object and a second object different from the first object, a first obtainment unit that obtains a pressed coordinate point which is a coordinate point on the screen where an input operation on the screen by a user is performed, and a determination unit that makes a determination as to an object selected by the input operation by comparing a first priority level set for a type of the first object disposed within a predetermined range from the pressed coordinate point and a second priority level set for a type of the second object disposed within the predetermined range.
