Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional input apparatus is used as a controller that only transmits control signals unilaterally to a simulation apparatus, then the device complexity is reduced, but the realism of board movement in virtual space is insufficient
Solution Approach 1:
The patent implements a feedback mechanism where the simulation apparatus determines tilt directions and angles based on user posture and virtual space state, then sends control signals back to the tilt mechanism to physically move the board. This closed-loop feedback system creates realistic board movement that responds dynamically to both user actions and environmental conditions, resolving the contradiction between simplicity and realism.
Solution Approach 2:
The simulation apparatus acts as an intermediary that processes both user input (force and moment data) and virtual environment state, then generates appropriate tilt commands. This intermediary layer coordinates between the physical input apparatus and virtual space, enabling realistic board movement without requiring direct complex wiring between all components.
2Reliability
If the board only responds to user input without environmental interaction, then the ease of operation is improved, but the realism of board sport experience is insufficient
Solution Approach 1:
The patent makes the board dynamically responsive by having the tilt mechanism continuously adjust board orientation based on real-time simulation of both user posture and virtual environment state. The board is no longer statically controlled but dynamically adapts to changing conditions, creating authentic board sport experience while maintaining natural operation through force sensing.
Solution Approach 2:
The simulation apparatus provides feedback about environmental conditions (road surface state, virtual space configuration) and integrates it with user input to determine board tilt responses. This feedback loop enables the board to react realistically to environmental factors while still being controllable by user actions, resolving the contradiction between operational simplicity and experiential realism.
3Reliability
If the tilt mechanism is controlled solely by user input without considering virtual space state, then the device complexity is reduced, but the realism of board interaction with environment is insufficient
Solution Approach 1:
The simulation apparatus serves as an intermediary that integrates both user input data (force and moment) and virtual environment state information, then generates appropriate tilt commands. This intermediary processing layer enables realistic board-environment interaction by coordinating physical input with virtual world conditions without requiring direct complex integration in the hardware.
Solution Approach 2:
The system implements feedback where the simulation apparatus continuously monitors both user actions and environmental state, then adjusts tilt mechanism commands accordingly. This feedback mechanism enables the board to respond realistically to environmental conditions (such as road surface variations) while maintaining a relatively simple hardware architecture through intelligent software control.

AI summary
An interface apparatus for providing a user with a board sport experience in a virtual space includes: a board on which the user is to board; a tilt mechanism that supports the board from below such that the board is tiltable; a force sensor that is provided to the board or the tilt mechanism and that detects a force and a moment which are applied from the user to the board; and an input and output section that provides a signal indicative of the force and the moment to a simulation apparatus configured to generate the virtual space and that acquires, from the simulation apparatus, a control signal for controlling the tilt mechanism so as to tilt the board.
