Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable display devices lack the ability to dynamically adjust their output based on external circumstances and user interactions, such as distance and target detection, which limits their adaptability and user experience.
Innovation Solution
A wearable display device equipped with a display unit, sound output unit, target detection unit, distance detection unit, and sound control unit that adjusts sound output based on detected targets and distances, allowing for personalized and context-aware audio feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the device outputs sound continuously to provide information feedback, then the user receives adequate information, but noise leakage to the surroundings increases
Solution Approach 1:
The sound output unit dynamically adjusts its operation based on detected distance to targets. When a target is detected within a predetermined distance, sound output is suppressed or stopped. When no target is detected or the target is beyond the distance threshold, sound output is enabled. This dynamic control resolves the contradiction by adapting sound output to real-time environmental conditions.
Solution Approach 2:
The device incorporates a distance detection unit that provides real-time feedback about the presence and distance of targets. The sound control unit uses this feedback to automatically adjust sound output levels. This feedback mechanism enables the system to intelligently balance information delivery to the user with noise prevention in the surrounding environment.
2Adaptability or versatility
If the device adjusts sound output based on detected targets and distances, then adaptability to external circumstances improves, but device complexity increases
Solution Approach 1:
The wearable display device integrates multiple functions into a single system: display output, sound output, target detection, distance detection, and sound control. The sound control unit serves as a central coordination component that manages sound output based on inputs from distance detection and target detection units. This multi-functional integration achieves high adaptability while managing complexity through a unified control architecture.
Solution Approach 2:
The device automatically detects targets and distances, then autonomously adjusts sound output without requiring manual user intervention. The sound control unit receives detection data and automatically makes decisions about sound output levels, enabling the device to adapt to external circumstances independently. This self-service capability enhances adaptability while reducing the complexity of user interaction.

AI summary
A head mounted display device is used by being mounted on a body of a user and includes an image display unit through which outside scenery is transmitted and which displays an image such that the image is visually recognizable together with the outside scenery. Further, the head mounted display device includes a right headphone and a left headphone outputting a sound. Further, the head mounted display device includes a target detection unit that detects a target of the user in the visual line direction; a distance detection unit that detects a distance between the detected target and the user; and an information output control unit that controls the output of the sound of the right headphone and the left headphone according to the detected distance.
