Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional input devices (mouse, keyboard, operator) are used for human-computer interaction, then the interaction can be performed with manual control, but it becomes difficult for disabled people or those engaged in hands-busy activities
Solution Approach 1:
The patent replaces manual mechanical input devices (mouse, keyboard, operator) with an eye-tracking based control system. The system uses infrared light to detect eye fixation points and converts gaze position into control signals, substituting mechanical hand-operated interfaces with an optical-eye interface that works for both able-bodied users and those with mobility limitations
Solution Approach 2:
The eye-controlled apparatus provides a universal interface that serves both traditional manual users and disabled users or those with hands-busy activities. The system can control various devices including mobile phones, tablets, computers, televisions, and air conditioners through a single eye-tracking mechanism, making it adaptable across different user groups and device types
2Adaptability or versatility
If eye tracking is implemented to enable hands-free control, then accessibility for disabled people and hands-busy users is improved, but the device complexity increases due to infrared modules and image processing requirements
Solution Approach 1:
The patent introduces an intermediary eye-tracking system that mediates between the user's natural gaze and the target device control. The system uses infrared light as an intermediary to illuminate the eyes, captures images through an imaging module, and processes these images to determine fixation points, creating a bridge between eye movement and device control without requiring direct mechanical interaction
Solution Approach 2:
The system creates a digital copy of the user's visual attention by detecting eye fixation points and mapping them to corresponding positions on the target device screen. This copying mechanism allows the system to interpret where the user is looking and translate that visual information into control commands, eliminating the need for physical contact with control interfaces
3Device complexity
If manual input devices are used, then the system structure remains simple, but the interaction efficiency decreases for users with disabilities or during hands-busy activities
Solution Approach 1:
The patent replaces manual mechanical input operations with automated eye-tracking detection. The system continuously monitors eye position using infrared illumination and image processing, automatically determining fixation points without requiring manual manipulation of control devices, thereby significantly improving interaction efficiency for disabled users and those with hands-busy activities
Solution Approach 2:
The eye-controlled system enables users to interact with devices using their natural visual attention without requiring manual dexterity. The system serves itself by automatically tracking eye movements, processing images, determining fixation points, and generating control signals based on the user's natural gaze behavior, making interaction efficient and intuitive

AI summary
The present disclosure discloses an eye-controlled apparatus, an eye-controlled method and an eye-controlled system. The eye-controlled apparatus includes a fixation point acquisition unit, a human eye action detection unit and a control signal generation unit. The fixation point acquisition unit is configured to acquire position information about the fixation point of human eyes on a device to be operated. The human eye action detection unit is configured to detect whether the human eyes take a pre-set action, and control the fixation point acquisition unit to transmit current position information about the fixation point of the human eyes on the device to be operated to the control signal generation unit when detecting the preset action taken by the human eyes. The control signal generation unit is configured to generate, based on a pre-stored position control correspondence table corresponding to the device to be operated, a control signal corresponding to the current position information about the fixation point of the human eyes on the device to be operated, and transmit the control signal to the device to be operated so as to control the device to be operated to execute a corresponding operation. The eye-controlled apparatus, the eye-controlled method and the eye-controlled system may effectively control the device to be operated using human eyes.
