Pointing Device Distance Adjustment for Accurate Aiming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pointing devices for home-use game machines face challenges in adjusting to varying user environments, such as different television screen sizes and distances between the display and the controller, leading to inaccurate aiming due to fixed configurations.
Innovation Solution
A storage medium with a program that adjusts the pointing device by determining the appropriate distance between the input apparatus and the display apparatus based on the display surface width, calculating the current distance, and notifying the user through visual, auditory, or vibrational cues to ensure accurate alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pointing device uses a fixed configuration for light emitting elements and display positioning, then the device structure is simple and easy to manufacture, but the device cannot adapt to varying use environments such as different television screen sizes and distances
Solution Approach 1:
The patent implements dynamic adjustment of the pointing device configuration by allowing the light emitting elements to be positioned at multiple predetermined locations rather than fixed positions. The control unit dynamically selects which light emitting elements to activate based on the detected display apparatus characteristics (screen size, distance), enabling the device to adapt to varying use environments without requiring physical reconfiguration or complex mechanical components.
2Measurement precision
If the pointing device uses predetermined fixed positions for light emitting elements, then the manufacturing process is simple, but the device cannot accurately point to the intended direction on the display screen for different screen sizes and distances
Solution Approach 1:
The patent changes the operational parameters of the light emitting elements based on detected display characteristics. The control unit calculates the appropriate light emitting element positions and activation patterns based on the screen size and distance to the display apparatus, thereby achieving accurate aiming for different configurations without requiring complex manufacturing processes or physical adjustments.
3Reliability
If the pointing device uses a fixed configuration, then the device structure is simple, but the gun controller points in a direction largely deviated from the direction instructed by the player in varying use environments
Solution Approach 1:
The patent implements a feedback mechanism where the imaging unit detects the display apparatus (screen size, distance), and the control unit uses this information to adjust which light emitting elements are activated and their effective positioning. This closed-loop feedback ensures that the pointing direction accurately reflects the player's intended direction regardless of the varying use environment, without requiring complex manual configuration adjustments.

AI summary
A pointing device includes a controller for pointing a position on a display surface by imaging an imaging objective such as two markers positioned with a predetermined interval therebetween in a vicinity of the display surface of a monitor. With the pointing device, a width of the display surface and the interval between the markers are obtained to determine an appropriate distance between the controller and the monitor. Further, a current distance between the controller and the monitor (markers) is calculated. Relation between the current distance and the appropriate distance is notified by such as image display or sound output. For example, an image indicating the appropriate distance and an adjustment image varying in size in conjunction with the current distance are displayed on the monitor.
