Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional two-dimensional video displays are used, then device complexity is reduced, but user immersion and suspension of disbelief deteriorate
Solution Approach 1:
The patent transitions from two-dimensional video displays to three-dimensional projected environments, creating immersive gaming experiences that surround users spatially. This dimensional change enables realistic environmental responses and enhances suspension of disbelief by eliminating the flat screen barrier between user and game world.
Solution Approach 2:
The patent introduces an intermediary tracking system using cameras and sensors to detect interface device positions and orientations. This intermediary layer enables the system to respond naturally to user movements, creating immersive experiences without requiring users to directly manipulate complex controls.
2Ease of operation
If directional targeting devices are fixed in stationary positions, then measurement precision is improved, but user freedom of movement deteriorates
Solution Approach 1:
The patent replaces fixed stationary positioning with dynamic tracking of interface devices as users move freely through three-dimensional space. The system continuously updates device positions and orientations in real-time, maintaining measurement precision while enabling complete freedom of movement within the gaming environment.
Solution Approach 2:
The patent substitutes mechanical encoder position feedback systems with optical and sensor-based tracking. This replacement eliminates the need for fixed mechanical mounting while maintaining or improving position detection accuracy through non-contact sensing methods.
3Ease of operation
If limited detection range is used, then device complexity is reduced, but environmental responsiveness and immersion deteriorate
Solution Approach 1:
The patent divides the detection system into multiple distributed cameras and sensors positioned throughout the environment. Each component handles a specific detection task, and the combined system achieves comprehensive environmental coverage with high responsiveness while keeping individual components manageable in complexity.

AI summary
There is provided an interactive device capable of providing input data to a computer program in response to user interactions, the interface device comprising a first position sensor reading a sensed location of the interface device having a free roaming movement in a three-dimensional space, a direction vector determination device determining a direction vector indicating an aiming direction, and a transmission system communicating aim information to an external device implementing the computer program. The transmission system may include a transmitter for the direction vector and/or a transmitter for the sensed location. The computer program can use the aim information and input data to support a projected 3D game environment or other application providing sensory feedback in response to the user interactions. Multiple interactive devices having unique identifiers may also be supported. The interactive device enables significant freedom to roam relative to implementing equipment, as compared to existing interactive devices having only a limited range of movement relative to implementing equipment.
