Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable computing systems face challenges in providing effective user interfaces that are intuitive and efficient for interacting with head-worn computers, particularly in environments where hands-free operation is necessary.
Innovation Solution
The development of external user interfaces, such as the pen 200, which incorporates cameras, IMUs, pressure sensors, and communication modules, allows for bi-directional communication with head-worn computers, enabling gesture recognition, distance control, and force interpretation to enhance interaction capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional user interfaces are used with head-worn computers, then the interface can be simple in structure, but it becomes difficult to operate in hands-free environments
Solution Approach 1:
The patent replaces traditional mechanical input devices (keyboard, mouse, touch screen) with gesture recognition technology. The head-worn computer captures video of user gestures and processes them to generate control commands, eliminating the need for physical contact with input devices while maintaining operational capability.
Solution Approach 2:
The patent introduces an external processing device as an intermediary between the user and the head-worn computer. This separate device handles the complex gesture recognition and command generation, allowing the head-worn computer to remain relatively simple while still providing sophisticated hands-free control capabilities.
2Adaptability or versatility
If external user interfaces with multiple sensors are implemented, then interaction capability is enhanced, but device complexity increases
Solution Approach 1:
The patent divides the user interface system into separate functional components: the head-worn computer handles video capture and basic processing, while an external device performs advanced gesture recognition and command generation. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining versatile interaction capabilities.
Solution Approach 2:
The patent implements a gesture recognition system that can identify multiple types of gestures (hand waves, finger points, circular motions) and map them to various control functions. This universal gesture interface can control different applications and functions, providing high adaptability without requiring separate specialized interfaces for each function.
