Wearable Display Overlaying Environmental Light Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Human-computer interaction technologies fail to effectively enhance user awareness of surrounding environments, particularly in wearable and mobile devices, leading to potential accidents due to unawareness of moving objects or changes in the environment.
Innovation Solution
A user interface apparatus and method that incorporates a display, a detector for changes in incident light or sound, and a controller to overlay detected changes onto the image or sound content, providing information about objects or sound sources, including type, velocity, distance, and location, to enhance user awareness without diverting attention from the primary content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If users focus on image content displayed on wearable devices, then viewing experience is improved, but awareness of surrounding environment deteriorates leading to potential accidents
Solution Approach 1:
The patent combines image content display with environmental change notification into a single integrated display system. The controller merges the image content from the display driver signal with environmental change information from the light/sound detectors, presenting both simultaneously on the same display to maintain user awareness of surroundings while viewing content
Solution Approach 2:
The display acts as an intermediary that translates environmental changes (detected by light/sound sensors) into visual representations overlaid on or alongside image content. This intermediary conversion allows indirect notification of environmental changes without requiring direct user attention to the environment itself
2Loss of information
If environmental information is displayed separately from image content, then user awareness of surroundings is improved, but complexity of the display system increases
Solution Approach 1:
The patent merges environmental information display with image content display into a single integrated system. The controller combines both types of information and presents them through the same display device, eliminating the need for separate display components and reducing overall system complexity
Solution Approach 2:
The display device is made multi-functional by using it to present both image content and environmental change notifications. This universal usage of a single component eliminates the need for dedicated separate displays for environmental information, thereby reducing device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively provides users with real-time awareness of their surroundings, minimizing the risk of accidents by overlaying relevant environmental information onto the existing content displayed on wearable or mobile devices, ensuring continuous use without compromising safety.
Implementation Method 1
a detector configured to detect a change in an incident light
Implementation Method 2
an event-based vision sensor configured to detect an event where the incident light varies and configured to time-asynchronously generate a signal indicating the change in the light
