Solution Overview
Problem
Existing device control systems require users to operate input devices multiple times to achieve desired functions, leading to decreased controllability and efficiency, especially when selecting target devices based on gaze direction.
Innovation Solution
A device control system that includes an input device, a detection device to detect user gaze direction or facial orientation, and a determination device to select and change the processing type of target devices accordingly, allowing for intuitive control through gaze-based selection and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the command target device is selected by user gaze detection, then the selection accuracy is improved, but the number of input device operations required increases
Solution Approach 1:
The system performs preliminary device selection based on gaze detection before the user operates the input device. By determining the command target device in advance through gaze direction analysis, the system prepares the correct device context, so that when the user presses the input device, the desired function is executed immediately without requiring multiple operations to switch between devices.
Solution Approach 2:
The patent replaces manual mechanical input operations with optical detection (gaze tracking). Instead of requiring users to physically navigate through device selections using buttons or switches, the system uses gaze detection sensors to automatically identify the intended target device, substituting mechanical interaction with optical field-based detection.
2Ease of operation
If gaze-based device selection is implemented, then the intuitiveness of control is improved, but the system complexity increases
Solution Approach 1:
The patent introduces a determination device as an intermediary component that bridges the gaze detection sensor and the multiple control devices. This determination device processes the gaze direction information and maps it to the appropriate command target device, serving as a mediator that translates optical detection data into device selection commands without requiring complex direct integration between sensors and all possible devices.
3Speed
If the target device changes processing type based on gaze direction, then the responsiveness is improved, but the reliability of command execution decreases
Solution Approach 1:
The system implements feedback by continuously monitoring gaze direction and using it to dynamically determine the command target device. The determination device receives gaze information, processes it to identify the intended device, and adjusts the command routing accordingly. This feedback loop ensures that the system responds to user intent in real-time while maintaining reliability through systematic processing of gaze data to confirm device selection.

AI summary
A device control system includes a first input device and a gaze detector. The first input device allows a command to be entered with respect to a target device selected from one or more devices. The gaze detector detects a user's gaze direction. The gaze detector determines, based on the gaze direction detected by the gaze detector, one device, selected from the one or more devices, to be the target device. A gaze detector makes the target device change, based on the gaze direction detected by the gaze detector, the type of processing to be performed in accordance with the command entered through the first input device.
