Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gaming systems face limitations in motion detection due to infrared communication range and accuracy, and accelerometers only measure acceleration, restricting motion sensing to a few directions.
Innovation Solution
A gaming object equipped with an orientation sensor that generates orientation data and an actuator that generates interaction data, transmitted via RF signals to a game console, allowing for more precise motion tracking and interaction with interactive items on a display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If IR communication is used to detect controller direction, then the system can detect orientation, but the communication range is limited and reliability decreases when the controller is too far, too close, or angled away from the IR sensor
Solution Approach 1:
The patent introduces an RF transceiver as an intermediary communication mechanism between the gaming controller and game console. Instead of relying directly on IR communication which has limited range and angle requirements, the system uses RF signals as a more reliable communication channel that can transmit orientation data and interaction data over greater distances and with broader angular tolerance, thereby resolving the contradiction between measurement precision and communication reliability
Solution Approach 2:
The patent replaces the IR optical communication system with an RF electromagnetic communication system. This substitution allows the gaming controller to maintain orientation detection capability while communicating reliably over extended ranges and various angles, eliminating the line-of-sight constraints and distance limitations inherent in IR communication
2Adaptability or versatility
If accelerometers are used to detect motion, then the system can sense movement, but only acceleration is measured limiting detection to a handful of directions
Solution Approach 1:
The patent combines multiple sensing technologies within the gaming controller: orientation sensors (such as gyroscopes and accelerometers) work together with RF transceivers and actuators. This merging of sensors allows the system to capture both linear acceleration and rotational orientation data, providing comprehensive three-dimensional motion detection that overcomes the directional limitations of accelerometers alone
Solution Approach 2:
The gaming controller is designed as a multi-functional device that performs orientation sensing, motion detection, wireless communication, and user interaction detection simultaneously. The orientation sensor suite provides universal motion detection capability across all three spatial dimensions, while the RF transceiver enables versatile data transmission to the game console, making the controller adaptable to various gaming scenarios

AI summary
A gaming object includes an orientation sensor that generates orientation data in response to the orientation of the gaming object. An actuator that generates interaction data in response to an action of a user. A transceiver sends an RF signal to a game device that indicates the orientation data and the interaction data. The game device generates display data for display on a display device that contains at least one interactive item, and wherein the at least one interactive item is interactive in response to the orientation data and the interaction data.
