Pointing Device Coordinate Consistency Across Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users may experience a change in feeling when operating a pointing device between different application programs, such as a game and a web browser, due to differences in the behavior of the designated position image.
Innovation Solution
A computer system with a coordinate designation system that produces base data for calculating position coordinates, allowing the system to function as a position coordinate obtaining unit and designated position image display unit, enabling seamless activation and display of the designated position image across different application programs, including notification of position coordinates between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user switches between different application programs (e.g., game application and web browser), then the user can access multiple functions, but the behavior of the designated position image changes between applications, causing confusion
Solution Approach 1:
The first application program acts as an intermediary that notifies the second application program of the position coordinates obtained by the first position coordinate obtaining unit. This mediator role ensures that the second application program receives and uses the same position coordinates, maintaining consistent designated position image behavior across different applications when activated from the first application program
Solution Approach 2:
The system segments the coordinate obtaining functionality into two separate units: a first position coordinate obtaining unit in the first application program and a second position coordinate obtaining unit in the second application program. This segmentation allows each application to have its own coordinate obtaining mechanism while still ensuring consistency through the notification mechanism when switching between applications

AI summary
To prevent a user from sensing change in feeling of operation of a pointing device. There is provided a computer system control method for controlling a computer system having a coordinate designation system for producing base data for calculating position coordinates, the method comprising the steps of obtaining the position coordinates calculated based on the base data; when a predetermined application program is activated from another application program, obtaining position coordinates notified by the other application program, and showing a designated position image on a display screen based on the position coordinates obtained; and when the predetermined application program is activated from an operating system, showing the designated position image on the display screen based on the position coordinates obtained at the step of obtaining the position coordinates.
