Ring Wearable Interface for Single-Handed Smart Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices require two-handed operation and visual interaction, making them difficult for users with disabilities or limited mobility to use and control other electronic devices effectively.
Innovation Solution
A ring-shaped wearable device with input and output devices on its inner and outer circumferential surfaces, enabling single-handed operation and voice control, along with wireless communication for controlling smart devices and environmental systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wearable devices use traditional form factors (glasses, watches, armbands), then they can be worn on the body, but they require two-handed operation and visual interaction which makes them difficult for users with disabilities to use
Solution Approach 1:
The patent transitions from traditional wearable form factors (glasses, watches, armbands) to a ring-shaped device worn on the finger, representing a dimensional change in placement and interaction. This allows users with disabilities to operate the device using finger movements rather than requiring two-handed manipulation or visual attention, thereby improving accessibility while maintaining wearability
2Volume of moving object
If wearable devices have small touchscreens, then they can be worn on the body, but users lacking fine motor control find the small touchscreens very challenging to use
Solution Approach 1:
The patent replaces traditional touchscreen mechanical interaction with voice recognition and motion sensing capabilities. The ring device includes microphones for voice commands and motion sensors to detect finger movements, eliminating the need for fine motor control required by small touchscreens while maintaining a compact wearable form factor
3Duration of action of moving object
If wearable devices require removal for recharging, then they can be used during the day, but they become useless while being recharged
Solution Approach 1:
The patent implements automatic background charging capabilities where the ring device can be recharged without removal through wireless charging integration or contactless charging mechanisms. The system preliminarily charges the device during periods of non-use or through ambient energy harvesting, ensuring continuous availability and eliminating the interruption of service during recharging
4Adaptability or versatility
If wearable devices require voice commands for input, then they can be used by users with limited motor control, but users lacking sight find navigating a GUI using screen-reader very slow and cumbersome
Solution Approach 1:
The patent introduces motion sensors and gesture recognition as an intermediary between voice commands and GUI navigation. Users can perform subtle finger movements detected by the motion sensors to navigate the interface, providing a faster and more intuitive control method for visually impaired users while maintaining the accessibility benefits for users with motor limitations
