VR Accessory Descriptor Interface for Third-Party Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality systems have limited compatibility with non-official or third-party accessories, restricting user interaction and experience due to poor recognition and processing of input-output data from diverse accessory kits.
Innovation Solution
A virtual reality system that includes a head-mounted display and a processing device capable of collecting descriptor information from accessory kits, obtaining accessory type identification, and processing input-output data to enable seamless interaction with various accessories, including official and third-party devices, through wireless communication and standard packet formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the virtual reality system uses limited official accessories only, then the system stability is improved, but the adaptability deteriorates
Solution Approach 1:
The patent implements a universal accessory interface system that allows the VR system to work with multiple types of accessories (official and third-party) through a standardized communication protocol. The processing device collects descriptor information from various accessories and identifies their types, enabling the system to handle different accessory functions (buttons, sensors, feedback outputs) through a unified interface, thus achieving multi-functionality while maintaining system stability
Solution Approach 2:
The system dynamically adjusts its operation based on the detected accessory type by changing processing parameters. When descriptor information is collected from an accessory, the system identifies the accessory type and modifies its data processing accordingly, allowing stable operation across different accessory configurations without requiring dedicated handling for each accessory type
2Adaptability or versatility
If the virtual reality system supports multiple accessory types, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent introduces an intermediary descriptor information system that mediates between diverse accessories and the VR processing system. Instead of directly handling complex accessory-specific protocols, the system uses standardized descriptor information as an intermediate layer to identify and process accessories. This intermediary approach simplifies the system architecture by providing a uniform interface for accessing accessory capabilities regardless of their original complexity
Solution Approach 2:
The system segments accessory information into standardized descriptor fields that can be independently processed. By collecting descriptor information in structured segments (accessory type, capabilities, parameters) rather than handling complete accessory-specific data streams, the system reduces processing complexity while maintaining support for multiple accessory types
Data Source
AI summary
A virtual reality system includes a head-mounted display and a processing device. The head-mounted display is configured for displaying a virtual reality content. The processing device is coupled to the head-mounted display device and communicated with an accessory kit. The processing device is configured to collect descriptor information from the accessory kit, obtain an accessory type identification of the accessory kit from the descriptor information, and process input-output data of the accessory kit according to the accessory type identification. The input-output data corresponds to interaction between at least one virtual reality object in the virtual reality content and the accessory kit.
