Optical Code Client Device for Biometric Display Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices with small, low-resolution displays, such as biometric devices, struggle to provide clear information to users, especially those with impaired vision, making it difficult to read biometric data in Aging-in-Place environments.
Innovation Solution
A client device that receives information from an optical code generated by a sensing device, converts it, and displays it on a selected display device in a larger format, eliminating the need for additional interfaces, thereby enhancing readability without complex conversions or transfers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information is displayed on the sensing device display, then the device structure remains simple, but the display readability is poor for users with impaired vision
Solution Approach 1:
The patent introduces an optical code as an intermediary carrier between the sensing device and the user's display device. The sensing device generates an optical code containing biometric information, which the user can then scan with their smartphone or other display device to view the information in a readable format. This intermediary approach resolves the contradiction by maintaining simple sensing device structure while achieving good display readability through the user's own devices.
2Ease of operation
If the display window is made larger to improve readability, then the display clarity improves, but the sensing device size increases
Solution Approach 1:
The patent extracts the display function from the sensing device itself and relocates it to the user's personal display devices (smartphones, tablets, computers). The sensing device only needs to generate and transmit the optical code, while the actual information display occurs on the user's larger, higher-resolution screens. This extraction resolves the contradiction by maintaining a compact sensing device while achieving large, clear display output through external devices.
3Ease of operation
If an optical code is generated and transferred to a remote display device, then the display readability improves, but the device complexity increases
Solution Approach 1:
The patent uses optical codes (such as QR codes) as a copyable representation of the biometric information. Instead of directly transmitting digital data or connecting devices, the information is encoded into a visual optical code that can be easily scanned and copied by the user's display device. This copying approach simplifies the system by using standard, widely-compatible optical code scanning capabilities already present in most smartphones, avoiding the need for specialized communication protocols or direct device-to-device connections.

AI summary
A client device coupled to an optical device provides for receiving from the optical device information associated with an optical code. The optical code is provided or otherwise generated by a sensing device that can be associated with a particular user, for example, a biometric sensing device associated with a aging-in-place user. The client device or a user causes the optical device to scan or otherwise obtain the information from the optical code. The client device converts the information to a format suitable for display on a display device based on one or more factors. The display of the converted information is at a size or resolution that allows a user to easily discern or otherwise read the converted information as compared to such information being displayed at the sensing device.
