Dual Transceiver Controller for Low Latency Wireless Gaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer simulation controllers, especially wireless ones, face significant latency issues due to inadequate solutions for wireless link performance, which affect the responsiveness of gamer input in computer games.
Innovation Solution
A computer simulation controller equipped with both Bluetooth and Wi-Fi transceivers simultaneously sends identical commands over both wireless channels, using the quickest arriving packet to ensure low latency and increased reliability, and negotiates the shortest path to the simulation console, whether local or remote, to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single wireless link (Bluetooth or Wi-Fi) is used for controller-to-console communication, then device complexity is reduced, but latency and reliability deteriorate due to inability to negotiate optimal transmission paths
Solution Approach 1:
The patent combines multiple wireless transceivers (Bluetooth and Wi-Fi) into a single controller device, enabling simultaneous operation of both communication protocols. This merging allows the system to leverage the strengths of each protocol - Bluetooth for low-latency local communication and Wi-Fi for high-bandwidth remote communication - thereby improving command transmission reliability without requiring the user to manually switch between protocols.
Solution Approach 2:
The controller is designed with multi-functionality by incorporating both Bluetooth and Wi-Fi transceivers, allowing it to operate across different communication scenarios (local and remote play). This universal design enables the controller to adapt to various network conditions and console locations, ensuring reliable command transmission regardless of whether the console is locally connected or accessed remotely via internet.
2Adaptability or versatility
If wireless transmission is used to enable remote play, then adaptability is improved, but latency increases due to network path variability
Solution Approach 1:
The system dynamically selects the optimal transmission path based on real-time network conditions and console location. When playing locally, Bluetooth provides low-latency direct communication. When playing remotely, Wi-Fi enables internet connectivity while the system negotiates the shortest available path through network routing. This dynamic adaptation ensures minimal latency regardless of play mode.
Solution Approach 2:
The dual transceiver system acts as an intermediary layer between the controller and console, providing multiple communication channels. The system can switch between direct Bluetooth connection for local play and Wi-Fi network path for remote play, effectively mediating the communication to minimize latency while enabling adaptability across different play scenarios.
3Reliability
If multiple transceivers are implemented to provide communication paths, then reliability improves, but device complexity increases
Solution Approach 1:
The controller automatically manages its own communication path selection and transceiver coordination without requiring external intervention. The system self-negotiates the optimal transmission path between controller and console, automatically switching between Bluetooth and Wi-Fi based on connection status and network conditions, thereby improving reliability while minimizing the complexity burden on the user.
4Speed
If Bluetooth is used for local communication, then latency is reduced, but adaptability to remote play deteriorates
Solution Approach 1:
The communication system is segmented into two distinct protocols serving different functions: Bluetooth handles low-latency local communication, while Wi-Fi handles high-bandwidth remote communication. This segmentation allows each protocol to be optimized for its specific use case - Bluetooth for speed in local play and Wi-Fi for adaptability in remote play - while the system seamlessly switches between them based on play mode.

AI summary
A computer simulation controller includes both a Bluetooth transceiver and a Wi-Fi transceiver. Player input to the controller generates commands that are sent using both transceivers, such that a receiving apparatus such as a game console or a web server can use the first-arriving one of the two commands to reduce latency.
