Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bending sensors are used to track body movements in virtual worlds, then measurement precision of body angles is improved, but device complexity increases due to integration of sensor processing systems
Solution Approach 1:
The patent introduces a virtual world processing apparatus as an intermediary component that specializes in processing bending sensor data. This mediator converts raw sensor readings into meaningful control information for virtual objects, thereby improving measurement precision while containing the complexity within a dedicated processing module rather than distributing it throughout the entire system.
Solution Approach 2:
The patent extracts the sensor processing function into a separate, dedicated virtual world processing apparatus. By taking out the complex sensor data processing from the general game console system and placing it in a specialized component, the main system remains simpler while still achieving high measurement precision for body angles.
2Adaptability or versatility
If multiple bending sensors are integrated to capture comprehensive body motion, then adaptability of motion tracking is improved, but device complexity increases
Solution Approach 1:
The virtual world processing apparatus is designed with multi-functionality to handle various types of bending sensors and multiple sensed locations. It can process data from different sensor configurations and adapt to various motion tracking requirements, thereby improving adaptability while managing complexity through a universal processing platform.
Solution Approach 2:
The patent segments the motion tracking system into multiple bending sensors placed at different body locations, with each sensor independently measuring local angles. The virtual world processing apparatus then integrates these segmented measurements to achieve comprehensive body motion capture, improving adaptability while distributing the sensing complexity across multiple simple sensor units.
3Speed
If real-time processing of bending sensor data is implemented, then speed of interaction is improved, but use of energy increases
Solution Approach 1:
The virtual world processing apparatus performs preliminary processing of bending sensor data by pre-calculating angle values and preparing control information in advance. This preliminary action reduces the computational burden during real-time interaction, thereby maintaining fast response speed while reducing the energy required during actual gameplay.
Solution Approach 2:
The system implements continuous processing of sensor data through the virtual world processing apparatus, which maintains a steady stream of control information generation. This continuous action optimizes energy usage by avoiding intermittent high-power processing bursts, thereby achieving real-time interaction speed with more efficient energy consumption.

AI summary
A virtual world processing apparatus and method are provided. An angle value is obtained by measuring an angle of a body part of a user of a real world using sensor capability, which is information on capability of a bending sensor, and is transmitted to a virtual world, thereby achieving interaction between the real world and the virtual world. In addition, based on the sensor capability and the angle value denoting the angle of the body part, control information is generated to control a part of an avatar of the virtual world, corresponding to the body part, and then transmitted to the virtual world. Accordingly, interaction between the real world and the virtual world is achieved.
