Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gaming controllers lack the ability to intuitively simulate complex movements and impacts, such as striking musical instruments or engaging in sword-fighting, due to their limited input mechanisms.
Innovation Solution
Incorporating a three-axis accelerometer arrangement in the controller to detect movements and orientations, allowing for the generation of inputs that simulate the timing and strength of impacts, which can be translated into aural, visual, and tactile feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional cross-switches, joysticks, and buttons are used for controller inputs, then the controller structure remains simple and easy to manufacture, but the ability to simulate complex movements and impacts is limited
Solution Approach 1:
The patent replaces traditional mechanical input mechanisms (cross-switches, joysticks, buttons) with an accelerometer-based detection system. The accelerometer arrangement detects controller movement characteristics to determine impact moments and swing strength, substituting mechanical input methods with a sensor-based system that provides enhanced simulation capability while maintaining relatively simple controller structure.
2Measurement precision
If an accelerometer arrangement is added to detect movements and orientations, then the simulation precision of impacts and swings is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent utilizes the accelerometer's ability to detect changes in motion parameters (acceleration, orientation) to determine impact moments and swing strength. By monitoring parameters such as acceleration thresholds and movement characteristics, the system achieves precise detection of impact events without requiring complex additional sensors or mechanisms.
3Adaptability or versatility
If multiple sensors and complex input mechanisms are used to enhance simulation capability, then the realism of gaming experience is improved, but the ease of operation and controller simplicity deteriorate
Solution Approach 1:
The accelerometer-based system allows the controller to automatically detect and interpret impact moments and swing strength through its own movement characteristics. The controller essentially detects its own motion state, eliminating the need for complex button combinations or intricate input mechanisms, thereby maintaining ease of operation while achieving realistic simulation.

AI summary
An example system and method is provided for detecting a moment of impact and/or strength of a swing based on moving a hand-held device including an accelerometer arrangement. A moment and a magnitude of simulated striking of the object are determined based on one or more accelerometer arrangement outputs resulting from the moving of the hand-held device. Using one or more of aural, visual and tactile outputs, the striking of the object is simulated in accordance with the determined moment of simulated striking and the determined magnitude of the simulated striking.
