Camera-Based Head Tracking for Intuitive Motion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling the motion of moving objects in applications require complex hardware configurations, such as joysticks or external keyboards, which complicate user interactions and negatively impact user experience.
Innovation Solution
A method and apparatus that obtain user motion state information, update the motion state of a moving object accordingly, and control its movement without the need for additional hardware, using camera-based tracking of head movements to translate user gestures into object motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional control methods using joysticks or external keyboards are employed, then control precision can be maintained, but device complexity and operation difficulty increase
Solution Approach 1:
The patent replaces mechanical control devices (joysticks, external keyboards) with an optical-based head tracking system. The camera captures head motion and converts it into control signals, substituting mechanical input methods with an optical-mechanical conversion approach that eliminates the need for additional hardware controllers.
Solution Approach 2:
The system creates a virtual copy of the user's head motion in the digital domain. By tracking real-world head movements with a camera and replicating them as control inputs for the moving object, the system transfers physical motion into virtual control without requiring specialized input devices.
2Adaptability or versatility
If additional hardware such as joysticks is added, then control functionality is enhanced, but control cost increases
Solution Approach 1:
The camera, which may already be present in the device for other purposes, is made multi-functional by using it for both its original function and for head tracking control. This eliminates the need for dedicated control hardware, reducing costs while maintaining control functionality.
Solution Approach 2:
The device uses its own existing resources (the built-in camera) to provide control functionality, rather than requiring external hardware. The system serves its own control needs through self-contained components already present in the device.
3Measurement precision
If mouse or keyboard control is used, then directional control accuracy is maintained, but user experience deteriorates due to complex operation
Solution Approach 1:
Instead of requiring the user to learn and adapt to traditional control interfaces (mouse/keyboard), the system inverts the approach by having the control interface adapt to the user's natural behavior. Head movements, which are intuitive and natural, become the control input method, reversing the traditional paradigm where users must adapt to the device.

AI summary
A method for controlling a moving object to move, an apparatus, a device, a computer-readable storage medium, and a computer program product are provided. The method includes: obtaining first motion state information, wherein the first motion state information is motion state information of a user; updating second motion state information of the moving object according to the first motion state information; and controlling the moving object to move according to the second motion state information.
