Reproduction Device with Contactless Localization for Ergonomic Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reproduction devices, such as electronic magnifiers, require significant muscle power and can be inconvenient for users with impaired vision due to the need to move the device along lines of text, making it difficult to maintain a comfortable reading position and accurately locate the start of new lines.
Innovation Solution
A reproduction device equipped with contactless localization means, such as optical sensors, infrared sensors, or ultrasonic waves, to determine the position of a movable indication body, allowing for the selection and registration of image portions without moving the device along lines of text, combined with an adjustable display for ergonomic reading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the reproduction device is moved along lines of text to reproduce successive parts, then the image portion can be registered and reproduced, but significant muscle power is required and the operation becomes inconvenient
Solution Approach 1:
The patent replaces the mechanical system of manually moving the reproduction device along text lines with an optical/electronic system. Localization means (optical sensors, infrared sensors, or ultrasonic waves) detect the position of an indication body (finger or pointing stick) on the text, and the reproduction device automatically positions the registered image portion corresponding to the detected location, eliminating the need for manual positioning effort.
Solution Approach 2:
The reproduction device performs self-positioning based on the detected indication body location. The system automatically determines which image portion to register and reproduce based on the position of the indication body, without requiring the user to manually move the device to specific locations.
2Ease of operation
If the reproduction device is moved along lines of text, then successive parts can be reproduced, but it is difficult to maintain a comfortable reading position and locate the start of new lines
Solution Approach 1:
The patent replaces manual mechanical positioning with automated optical/electronic position detection. Localization means precisely track the indication body's position on the text, enabling accurate reproduction of the corresponding image portion while the user maintains a comfortable, stationary reading position. The system automatically identifies line starts and transitions without requiring user judgment.
3Ease of operation
If contactless localization means are used to determine indication body position, then muscle power requirements are reduced and reading becomes more ergonomic, but the device complexity increases
Solution Approach 1:
The patent introduces contactless localization means (optical sensors, infrared sensors, or ultrasonic waves) to detect the indication body position without physical contact. This replaces the mechanical interaction where the user physically moves the device, significantly reducing muscle power requirements and improving ergonomics despite adding sensor-based subsystems.
