Gamepad Displacement Detection for Precision Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gamepads lack displacement detection capabilities, making it difficult to control game characters or cursors on screens quickly and accurately, especially in first-person shooting games, as they rely solely on joysticks and buttons, which are inflexible and lack precision.
Innovation Solution
Incorporating a displacement detection device, such as an optical, mechanical, or magnetic displacement detection module, into the gamepad to enable precise and rapid movement control of on-screen elements by detecting axial displacement of an operating element within a defined detection channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a joystick is used to control the target image movement, then the control is easy to operate, but the movement speed and precision cannot be both fast and accurate
Solution Approach 1:
The patent merges the joystick module with a displacement detection device (optical or mechanical) into an integrated operating element. The joystick provides directional input while the displacement detection device measures the actual movement distance and speed of the operating element, combining the ease of joystick operation with the precision of displacement measurement to achieve both fast and accurate target image control.
Solution Approach 2:
The patent replaces pure mechanical joystick control with a hybrid system that incorporates optical or mechanical displacement detection. Instead of relying solely on joystick angle and push duration, the system uses displacement detection modules to objectively measure the operating element's movement, substituting subjective mechanical control with objective measurement to improve precision while maintaining operational ease.
2Speed
If the joystick is pushed at a large angle for fast cursor movement, then the speed increases, but the precision of positioning decreases
Solution Approach 1:
The displacement detection device provides real-time feedback on the operating element's position, movement distance, and speed. This feedback allows the system to dynamically adjust the target image control, enabling the user to move the cursor quickly when needed while maintaining precise positioning capability, as the system continuously monitors and responds to the actual displacement rather than relying solely on joystick angle.
3Measurement precision
If a mouse is used to achieve fast and accurate cursor control, then the precision and speed improve, but the requirement for a physical desktop surface reduces comfort
Solution Approach 1:
The patent makes the gamepad multi-functional by integrating both joystick capabilities and displacement detection functionality into a single device. The operating element can operate in air like a gamepad while providing mouse-like precision through displacement measurement, eliminating the need for a physical desktop surface and maintaining operational comfort while achieving high precision cursor control.
