Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of near-eye display devices requires both hands for control, leading to interruptions in the user's work process and reduced efficiency due to switching between different tasks.
Innovation Solution
A near-eye display device equipped with a transparent electrode layer on the lens to detect capacitance changes at the position of the human eye, allowing control through eye movements, such as opening and closing, to reduce the need for hand-based interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the near-eye display device is controlled by hand gestures, then the device can be operated, but the user's hands must switch between work tasks and device control, reducing overall efficiency
Solution Approach 1:
The patent replaces the mechanical hand gesture control system with an optical/electrical eye tracking system. The transparent electrode layer detects eye movements through electrical signals, substituting the mechanical interaction of hand gestures with a non-contact optical detection method. This allows users to control the device without involving hands, thereby maintaining work continuity and improving productivity.
2Adaptability or versatility
If hand gestures are used for control, then the device responds to user input, but the control process interrupts the user's continuous work flow
Solution Approach 1:
The patent introduces eye movements as an intermediary control mechanism between the user and the device. Instead of direct hand interaction that interrupts work, the eye tracking system serves as a mediator that captures subtle eye movements to generate control commands. This intermediary system enables continuous work while maintaining device controllability through natural, non-intrusive eye gestures.
3Extent of automation
If transparent electrode layer is added to the lens, then eye-based control becomes possible, but the device structure becomes more complex
Solution Approach 1:
The patent makes the transparent electrode layer serve multiple functions: it maintains optical transparency for vision, enables capacitance sensing for eye detection, and integrates with the existing lens structure. By designing the electrode layer to fulfill multiple roles simultaneously, the patent reduces the need for separate components and minimizes overall device complexity while achieving automated eye command recognition.
