Presbyopia-Aware Content Switching Between Handheld and Wearable Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in viewing content on devices for extended periods due to their eye conditions, particularly presbyopia, leading to discomfort and reduced readability on devices like smartphones.
Innovation Solution
A content presentation engine that determines eye conditions and content characteristics to switch presentation from a first device to a second device, such as from a smartphone to a head-mountable device, adjusting display settings like distance and resolution to enhance readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is displayed on a handheld device like a smartphone, then the device is portable and easy to carry, but the display distance is too close for users with presbyopia to view content comfortably
Solution Approach 1:
The patent introduces a wearable computing device as an intermediary between the handheld device and the user's eyes. This intermediary device receives content from the handheld device and presents it at an optimal viewing distance for users with presbyopia, thereby resolving the contradiction between portability and ease of viewing.
Solution Approach 2:
The system transitions the display from a close-range handheld interface to a wearable device that positions content at a farther distance from the user's eyes. This dimensional change in display distance allows users with presbyopia to view content comfortably while maintaining the portability benefit of wearable technology.
2Adaptability or versatility
If content is displayed on a handheld device, then the device can be easily carried, but the display does not satisfy presentation criteria for users with presbyopia
Solution Approach 1:
The system dynamically determines whether to present content on a handheld device or a wearable computing device based on real-time detection of presbyopia. This dynamic adaptation ensures that content is always presented on the most suitable device, maintaining both flexibility and presentation suitability.
Solution Approach 2:
The system uses feedback from presbyopia detection to automatically select the appropriate display device. By continuously monitoring eye conditions and adjusting content delivery accordingly, the system ensures reliable presentation suitability while maintaining device flexibility.
3Object-affected harmful factors
If content is displayed on a wearable device, then the viewing distance is optimized for presbyopia, but the device requires additional wearability infrastructure
Solution Approach 1:
The wearable computing device serves multiple functions: it acts as a display device, a communication interface with the handheld device, and a presbyopia compensation mechanism. This multi-functionality reduces the need for separate components, thereby managing system complexity while achieving eye strain reduction.
4Adaptability or versatility
If the system switches content presentation between devices, then the appropriate device can be selected based on eye condition, but the system complexity increases
Solution Approach 1:
The system performs self-service by automatically detecting presbyopia and selecting the appropriate display device without requiring manual user input. This automation simplifies the switching mechanism while maintaining high adaptability in device selection based on eye conditions.

AI summary
Various implementations disclosed herein include devices, systems, and methods for switching presentation of content between devices. In some implementations, a method includes obtaining information regarding an eye condition. In some implementations, the method includes determining whether a first display of a first electronic device that is presenting content satisfies a presentation criterion based on the eye condition and a characteristic of the content. In some implementations, the method includes, in accordance with a determination that the first display does not satisfy the presentation criterion, triggering a second electronic device with a second display that satisfies the presentation criterion to present the content.
