Co-located Networked Game Devices Shared Coordinate Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive gaming technologies lack the ability to effectively utilize co-located, networked devices to provide a rich, location-aware and direction-aware gaming experience, where devices can share and project their positions and orientations in real-time, enhancing the gaming environment.
Innovation Solution
The implementation of a system where co-located, networked interactive game devices share a common reference coordinate frame, using communication technologies like Bluetooth or Wi-Fi, to project and maintain device states, allowing each device to determine the relative positions and orientations of other devices, enabling an enriched interactive gaming experience through shared device states and sensor data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If co-located networked devices share device states using communication technologies, then the interactive gaming experience is enriched with real-time position and orientation awareness, but the device complexity and communication requirements increase
Solution Approach 1:
The system segments the gaming experience into individual device states (position, orientation, time) that can be independently maintained and shared. Each device processes its own sensor data locally and only exchanges essential state information with other devices, reducing communication overhead while maintaining rich interactive capabilities
Solution Approach 2:
The device state sharing mechanism is designed to be universal and adaptable to various gaming scenarios. The same coordinate frame transformation and state sharing infrastructure supports different game types (e.g., Laser Tag, virtual maze navigation), allowing the system to maintain versatility without proportionally increasing complexity
2Measurement precision
If devices project relative positions and orientations into local coordinate frames in real-time, then measurement precision of player locations is improved, but the computational requirements and processing time increase
Solution Approach 1:
The system establishes a common reference coordinate frame beforehand that all devices agree upon. This pre-defined coordinate system allows devices to directly transform their local sensor readings into the shared frame without complex real-time calculations, maintaining measurement precision while reducing processing time
Solution Approach 2:
The system transforms physical sensor parameters (accelerometer readings, gyroscope data) into standardized coordinate frame parameters (position, orientation angles). This parameter transformation enables precise position and orientation determination while using efficient mathematical operations that minimize processing time

AI summary
An interactive game environment includes two or more co-located, networked, direction and location aware interactive game devices. The game devices share a common reference coordinate frame (e.g., a three-dimensional Cartesian coordinate frame). Each game device maintains its own device state (e.g., position, orientation, time) in the reference coordinate frame. Each interactive game device shares its device state with the other interactive game devices using communication technology (e.g., Bluetooth, Wi-Fi, cellular). Each interactive game device can use the device states of the other interactive game devices to project the relative positions and orientations of the other interactive game devices into a local, fixed coordinate frame of the interactive game device. These projections allow each interactive gaming device to know the position and orientation of the other interactive game devices in an interactive game environment defined by the reference coordinate frame.
