Projection Lens Interface for Wearable Display Size Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The size restrictions of electronic devices, such as smart watches, limit the area of their displays and human-computer interaction interfaces, resulting in a poor user experience due to the confined interaction space.
Innovation Solution
An electronic device with a frame structure, a first display component, a second display component, and M sensors that projects a graphical interaction interface onto a user's arm, allowing interaction operations to be performed and the interface to be changed based on user input, thereby bypassing size limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the size of the electronic device is reduced to meet application scenario requirements, then the device becomes more portable and wearable, but the area of the display and human-computer interaction interface is restricted
Solution Approach 1:
The patent extends the interaction interface from the two-dimensional display surface to the three-dimensional surface of the user's body (arm, wrist, or other body parts). By projecting the graphical interaction interface onto the user's body and using sensors to detect gestures on this extended surface, the system effectively increases the interaction area without increasing device size, resolving the contradiction between device portability and interaction area.
2Area of stationary object
If the display area is increased to improve user experience, then the interaction interface becomes more usable, but the device size must be increased
Solution Approach 1:
The patent introduces the user's body as an intermediary medium between the device and the interaction interface. Instead of expanding the display area on the device, the system uses the user's body surface as a canvas for the graphical interaction interface, with sensors detecting gestures on this intermediary surface. This allows the interaction area to be effectively expanded without increasing device dimensions.
3Volume of moving object
If the device is made compact for wearability, then it can be worn around the wrist, but the interaction area becomes confined and user experience deteriorates
Solution Approach 1:
The patent resolves the contradiction between compact device size and ease of operation by extending the interaction space from the limited device surface to the user's body surface. Sensors detect gestures on the body (such as sliding on the arm or wrist), providing a larger operational area that improves user experience while maintaining device compactness for wearability.
Applied Scientific Principles
