Head Tracking Screen Control via Camera Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screen controlling methods, such as touch sensing technologies, face limitations in user convenience due to low touch sensitivity, especially when users wear gloves or their fingers are covered, and repetitive interactions lead to user fatigue.
Innovation Solution
A method and apparatus that utilize a camera module to track a user's head movements, allowing the screen to be controlled by shifting content regions without the need for additional input devices, enabling users to select desired content through simple head gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch sensing technology is used to control the screen, then the device can be controlled without additional input devices, but touch sensitivity is low and control becomes difficult when the user wears gloves or has fingers covered
Solution Approach 1:
The patent replaces the mechanical touch sensing system with an optical recognition system using a camera module to detect head movements and gestures. This substitution eliminates the dependency on direct finger contact with the screen, allowing users to control the device through head movements and gestures without requiring physical touch, thereby solving the problem of low touch sensitivity when wearing gloves or having covered fingers.
Solution Approach 2:
The patent introduces head movements and gestures as an intermediary between the user and the screen control system. Instead of direct finger contact, the user's head movements are captured by the camera module and translated into screen control commands. This intermediary mechanism allows for reliable control in conditions where direct touch is not feasible.
2Reliability
If conventional input devices like mechanical key buttons or remote controllers are used, then control functions are available, but the user experience is less convenient compared to touch sensing
Solution Approach 1:
The patent merges the camera module, originally designed for photography or video functions, with the input control system. By combining the existing camera hardware with gesture recognition algorithms, the system achieves both image capture functionality and contactless control capability, eliminating the need for separate mechanical buttons or remote controllers while enhancing user convenience.
Solution Approach 2:
The patent makes the camera module serve multiple functions: traditional photography/video capture and gesture-based input control. This multi-functionality eliminates the need for dedicated input devices, as the camera system can both capture media and interpret user gestures for screen control, providing a universal control mechanism that enhances convenience without sacrificing control reliability.
3Adaptability or versatility
If repetitive finger contacts with the screen are used for control, then various functions can be accessed, but the user becomes tired and inconvenient
Solution Approach 1:
The patent transitions the control interaction from a two-dimensional screen surface (requiring repetitive finger contacts) to a three-dimensional space involving head movements and gestures. By utilizing spatial movements in multiple dimensions, the system allows users to access various functions through natural head motions rather than repetitive tapping or scrolling, significantly reducing user fatigue while maintaining full functionality access.
Solution Approach 2:
The patent replaces static, repetitive finger contacts with dynamic head movements and gestures. The camera module continuously tracks head position and motion, translating these dynamic movements into control commands. This dynamic interaction method allows users to navigate and access functions through natural, fluid head motions rather than repetitive mechanical finger actions, reducing fatigue while preserving adaptability across all device functions.

AI summary
Controlling a screen by tracking user's head using a camera module is described, comprising: (a) when a request for displaying contents is received, displaying a plurality of content regions on a screen and tracking the head of the user looking at the screen through the camera module; and (b) when it is determined in the tracking that the head of the user moves in a specific direction in a state where information on a first content is displayed in a central content region among the plurality of content regions, displaying, in the central content region, information on a second content which was displayed in a peripheral content region, the peripheral content region being positioned in the specific direction or in a direction opposite to the specific direction from the central content region.
