Innovation Solution
A portable gaming device with a display, joystick, and position sensor that integrates signals from both components using weighted aggregation and dynamic scaling functions to enhance control accuracy and immersion, allowing users to maneuver the device and joystick simultaneously for precise interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touchscreen interface is used for control, then the interface is easy to operate, but the control precision deteriorates because the user's finger is larger than the pixel
Solution Approach 1:
The patent combines multiple control interfaces (touchscreen, accelerometer, gyroscope, joystick) into a single hybrid control system. The touchscreen provides easy operation for general navigation, while the accelerometer and gyroscope provide precise control for positioning and aiming, resolving the contradiction between ease of operation and control precision.
Solution Approach 2:
The control device is designed to perform multiple functions through different input methods. The same device can be used for coarse positioning via touchscreen, precise aiming via accelerometer/gyroscope, and manual override via joystick, making it universally applicable for various control scenarios without sacrificing either ease of operation or precision.
2Ease of operation
If an accelerometer-based interface is used for aiming, then the interface is intuitive, but the control precision deteriorates due to hand tremors
Solution Approach 1:
The patent merges accelerometer-based intuitive control with joystick-based precise control. The accelerometer provides intuitive motion-based aiming, while the joystick offers stable, tremor-resistant manual control. Users can switch between or combine these methods depending on the situation, resolving the precision issue caused by hand tremors.
Solution Approach 2:
The system dynamically adjusts control sensitivity and integration methods based on detected motion patterns. When steady aiming is detected, the system can apply smoothing algorithms to reduce the impact of minor tremors. When rapid movement is detected, the system switches to more responsive control modes, optimizing precision across different operational states.
3Stability of the object's composition
If a stationary screen is used for display, then the display is stable, but the user immersion deteriorates because the user cannot move around
Solution Approach 1:
The patent implements dynamic display orientation that automatically adjusts the screen rotation and orientation based on the device's physical orientation in space using accelerometer and gyroscope data. This allows the display to remain stable and readable while adapting to different user positions and movement, enhancing immersion without sacrificing stability.
Solution Approach 2:
The system adds the spatial dimension to the display experience by enabling the screen to rotate and orient in three-dimensional space according to device orientation. This transforms the static two-dimensional display into a dynamic spatial interface that adapts to user movement, improving immersion while maintaining display stability through software-based orientation management.
4Speed
If joystick signal overrides position sensor signal, then the control response is fast, but the usability deteriorates because users cannot use both controls simultaneously
Solution Approach 1:
The patent merges joystick control with position sensor (accelerometer/gyroscope) control into a unified control system using weighted aggregation. Instead of one overriding the other, both inputs are combined with dynamically adjusted weights based on the current game context, allowing users to utilize both controls simultaneously for enhanced usability while maintaining fast response through the responsive joystick input.

AI summary
A human interface device (HID)-compatible portable gaming device includes a display; a position sensor; a joystick; and a processor in communication with the display, the joystick, and the position sensor. The processor has programmed instructions that, when executed, cause the processor to receive a first signal from the position sensor indicating a change in orientation of the portable gaming device, receive a second signal from the joystick indicating a change in position of the joystick, assign a first weight to the first signal and a second weight to the second signal; aggregate the first signal with the second signal based on a weighted sum of the weighted first signal and the weighted second signal to obtain a third signal, and update a user interface on the display according to the third signal.
