Content Guide Marker for Hemianopia Video Rehabilitation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hemianopia, a disorder causing vision loss in half the visual field, significantly impairs daily activities and video watching due to reduced information acquisition, as individuals with this condition often make compensatory eye movements that divert attention from informative areas in videos.
Innovation Solution
A method involving positioning a patient in front of a display with a video clip or image, marking a region of interest with a content guide to direct attention, thereby improving information acquisition and reducing symptoms of hemianopia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If individuals with hemianopia make compensatory eye movements into their blind hemifield, then they can detect objects in the blind area, but they spend less time fixating highly-concentrated informative areas in video
Solution Approach 1:
A content guide marker is introduced as an intermediary element that visually indicates the location of highly-concentrated informative areas in video content. This marker guides individuals with hemianopia to directly fixate on important regions without needing to make compensatory eye movements into their blind hemifield, thereby resolving the contradiction between detecting blind area objects and maintaining fixation on informative areas.
2Area of stationary object
If individuals with hemianopia make compensatory eye movements into their blind hemifield, then they can expand their visual search area, but information acquisition from video content is reduced
Solution Approach 1:
Instead of uniformly expanding the visual search area through compensatory eye movements, the content guide marker applies local quality enhancement by specifically highlighting the precise location of highly-concentrated informative areas. This allows individuals with hemianopia to maintain a stable fixation on the most important region rather than分散ly scanning across the blind hemifield, thereby improving information acquisition efficiency.

AI summary
The current subject matter relates to rehabilitation using a content guide for viewing video, for example as a vision rehabilitation aid for individuals with hemianopia or as a rehabilitation aid for individuals with attention disorders. The current subject matter includes providing video in which a region of interest of the image is specified with a marker, referred to herein as a content guide. The content guide can include a circle surrounding the region of interest. By providing video with a content guide to direct viewers to a region of interest in the video, information acquisition by the viewers is improved. Such an approach can aid individuals with vision deficits or attention disorders. The current subject matter can also be used as a therapy for spatial neglect.
