Offsetting Touch Input to Prevent Finger Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In portable game machines with touch panel displays, the small screen size makes it difficult for players to select and position objects accurately due to finger obstruction, leading to reduced visibility and interest in the game.
Innovation Solution
The implementation of finger contact detecting and position computing means, object display position computing, and display form change mechanisms to maintain a visible gap between the finger and selected objects, ensuring clear visibility and accurate object positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display size is made small to fit in portable devices, then the portability is improved, but the visibility of objects on screen is worsened due to finger obstruction
Solution Approach 1:
The patent extracts the harmful effect of finger obstruction by separating the object display position from the finger contact position. The computing means calculates a display position that is offset from the detected finger position, effectively removing the obstruction problem while maintaining the small display size for portability.
Solution Approach 2:
The patent introduces computing means as an intermediary between the finger contact detection and object display. This intermediary processes the finger position information and determines an appropriate display position that avoids obstruction, allowing the system to maintain both small size and good visibility.
2Speed
If the object is displayed at the position contacted by the finger, then the response speed is improved, but the visibility of the object is worsened because the finger blocks the view
Solution Approach 1:
The patent removes the conflict between response speed and visibility by extracting the object display from the exact finger contact position. The computing means determines a nearby display position that maintains quick response while eliminating the visual obstruction caused by the finger.
Solution Approach 2:
The patent applies local quality by adjusting the display position based on the local condition of finger contact. Instead of a uniform display position, the system dynamically adjusts the object position relative to the specific finger contact location, ensuring visibility while maintaining responsiveness.
3Measurement precision
If the player repeatedly moves the object to find the correct position, then the positioning accuracy is improved, but the time consumption increases and player interest decreases
Solution Approach 1:
The patent applies preliminary action by pre-calculating the optimal display position based on the detected finger contact position. The computing means determines the appropriate object position in advance, eliminating the need for repeated player adjustments and reducing time consumption while maintaining positioning accuracy.

AI summary
A portable game machine with a display which also serves as a touch panel type input portion is comprised of means for detecting a contact between a finger of a player and a screen, means for computing a coordinate position of the finger on the screen, means for computing and determining the coordinate position where the object to be displayed on the display is displayed so as to separate a predetermined distance from the coordinate position of the finger and to create a gap between the object displayed on the display and a periphery of the finger contacted with the screen, and object display means for displaying the object at the computed and determined coordinate position on the display.
