Game Controller Input Mixing for Precise Target Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current user interfaces for controlling the position of targets in gaming environments, such as game screens, often lack operability and precision, particularly when using directional inputs and sensors to move characters or objects.
Innovation Solution
A control device comprising a first receiving unit for directional inputs, a second receiving unit for sensor data from a controller with a three-axis acceleration sensor and gyro sensor, and a movement control unit that combines these inputs to move targets on a screen, allowing for both analogue stick manipulation and fine adjustments via controller position or attitude changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple input methods (directional keys, analogue sticks, sensor-based control) are combined to improve target movement control, then ease of operation and precision are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple input methods (directional keys, analogue sticks, and sensor-based control) into a single integrated input device. The control unit processes inputs from any of these methods and generates appropriate movement commands, allowing users to switch between different control modes without needing separate devices. This merging approach improves ease of operation while managing device complexity through unified processing logic.
Solution Approach 2:
The input device is designed with multi-functionality, where a single device can operate in multiple modes: traditional button/stick control for general movements, and sensor-based control (using acceleration sensors or gyroscopes) for alternative control methods. The control unit automatically or manually switches between these functions, making the device universal and adaptable to different user preferences and situations.
2Measurement precision
If sensor-based control is added to detect controller position and attitude for more precise target movement, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The control unit serves as an intermediary between the sensors (acceleration sensors, gyroscopes) and the target movement system. It processes the raw sensor data, interprets controller position and attitude, and converts this information into appropriate movement commands. This intermediary approach allows high measurement precision from sensors while managing complexity by centralizing the processing logic in the control unit rather than distributing it throughout the system.
Solution Approach 2:
The patent replaces traditional mechanical control mechanisms (purely button-based or stick-based input) with sensor-based detection systems. Acceleration sensors and gyroscopes detect controller orientation and movement without mechanical contact, providing more precise and continuous measurement of controller position and attitude. This substitution improves measurement precision while reducing mechanical wear and increasing reliability.
3Ease of operation
If both directional input and sensor input are processed simultaneously to move the target, then operability is enhanced, but information processing complexity increases
Solution Approach 1:
The control logic dynamically adjusts how it processes input based on the current state. When sensor-based control is active, the system continuously updates target position based on controller attitude changes. When directional keys or analogue sticks are used, the system processes discrete input commands. The control unit can switch between these dynamic processing modes, allowing enhanced operability while managing information processing complexity through adaptive logic rather than static, overly complex processing for all input types simultaneously.

AI summary
A game device comprises: a first receiving unit configured to receive an input direction from a controller comprising an input interface for accepting an input direction in which to move a target displayed on a screen of a display device; a second receiving unit configured to receive, from a sensor that detects the position or the attitude of the controller, information relating to the position and the attitude of the controller; and a movement control unit configured to move the position of the target based on both of the direction received by the first receiving unit and the information relating to the position or the attitude of the controller received by the second receiving unit.
