Smart Ring Gesture Messaging via Eyewear Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable electronic devices, such as smartphones and smart rings, lack an efficient method for composing messages without physically typing, especially in scenarios where a mobile device is not readily available.
Innovation Solution
A message composition and sharing system that utilizes a handheld device, like a smart ring, to track hand motion and project a keyboard onto a display, allowing users to select characters and compose messages through gesture recognition, with the eyewear device overlaying a trace of the hand motion onto the keyboard in real-time and identifying candidate words based on the motion path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical typing is used to compose messages, then message composition accuracy is improved, but operation time and effort increase significantly
Solution Approach 1:
The patent replaces the mechanical typing system with an optical gesture recognition system. The wearable device captures hand motion trajectories through sensors, and the eyewear device processes these trajectories to identify selected characters on a projected keyboard, substituting physical key presses with gesture-based selection.
Solution Approach 2:
The patent introduces a trace overlay as an intermediary visual element that connects hand motion to character selection. The trace is projected onto the keyboard and follows the hand's movement path, serving as a mediator that maps physical gestures to textual input without requiring direct contact with keys.
2Ease of operation
If a mobile device is available for message composition, then messaging functionality is improved, but device portability and accessibility worsen
Solution Approach 1:
The patent divides the messaging system into separate functional components: a wearable device for gesture capture and a lightweight eyewear device for display and processing. This segmentation allows the system to function without a traditional mobile device, improving portability while distributing complexity across multiple simple components.
Solution Approach 2:
The wearable device serves multiple functions including gesture recognition, trajectory tracking, and wireless communication, while the eyewear device provides display, processing, and messaging capabilities. This multi-functionality eliminates the need for a separate mobile device, enhancing accessibility.
3Measurement precision
If traditional keyboard typing is used, then character selection precision is improved, but user effort and operation complexity increase
Solution Approach 1:
The patent transforms the static keyboard interaction into a dynamic gesture-based system. The keyboard is projected and the trace dynamically follows hand motion, allowing character selection through movement rather than static key pressing. This maintains precision while reducing effort.
Solution Approach 2:
The patent adds a temporal and spatial dimension to character selection by using hand motion trajectories in three-dimensional space. Instead of two-dimensional key presses, the system captures motion paths through space and time, mapping these trajectories to character selection on the projected keyboard.
Data Source
AI summary
Systems, devices, media, and methods are presented for composing and sharing a message based on the motion of a handheld electronic device such as a ring. The methods in some implementations include presenting a keyboard on a display, collecting course data associated with a course traveled by the ring, and overlying a trace onto the keyboard, such that the trace is correlated in near real-time with the course traveled by the ring. In some implementations the display element is part of a portable device, such as the lens of an electronic eyewear device. Based on the course data relative to the key locations on the keyboard, the system identifies and presents candidate words to be included in a message.
