Wearable Display Force-Sensing VR to Live View Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable image display apparatuses that provide 360° virtual reality experiences can obstruct the user's view and pose safety risks due to their immersive nature, as users may not be aware of their surroundings, necessitating a method to switch between virtual reality and live-view modes quickly.
Innovation Solution
An image display apparatus equipped with sensors and a processor that detect external forces or movements to activate a camera and switch between virtual reality and live-view modes, allowing users to capture and display external images, adjust brightness, and add augmented reality elements, enabling seamless transitions between modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image display apparatus operates in virtual reality mode to provide immersive 360° experience, then user experience quality is improved, but user safety deteriorates due to obstruction of visual field
Solution Approach 1:
The system dynamically switches between virtual reality mode and live view mode based on detected external forces. When a force is applied to the apparatus, it transitions from immersive VR mode to live view mode, allowing users to quickly become aware of their surroundings and respond to potential hazards, thus resolving the safety issue while preserving VR experience quality during normal use
2Adaptability or versatility
If the apparatus occupies the entire visual field to provide immersive VR experience, then adaptability is improved, but ease of operation deteriorates due to reduced situational awareness
Solution Approach 1:
The apparatus dynamically adjusts its operational state between full immersive VR mode and live view mode. During normal operation, it provides complete VR immersion, but upon detecting external forces indicating user movement or potential hazards, it transitions to live view mode to restore situational awareness, thus maintaining ease of operation while preserving immersive capability
3Object-affected harmful factors
If the system continuously monitors external forces to enable quick mode switching, then user safety is improved, but device complexity increases
Solution Approach 1:
The system replaces complex continuous visual monitoring or manual user input mechanisms with simple force sensing. By using force sensors to detect physical interactions with the apparatus, the system achieves safety monitoring with minimal added complexity, as force sensors are straightforward components that provide clear binary signals for mode switching decisions
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
Enables users to safely switch between virtual reality and live-view modes by detecting external forces or movements, allowing for awareness of surroundings and enhancing the user experience with augmented reality features.
Implementation Method 1
The sensor may be further configured to measure a movement speed of the image display apparatus, and the processor may be configured to compare a threshold value with a change of the movement speed to determine whether the external force is applied to the image display apparatus
Data Source
AI summary
An image display apparatus includes a sensor configured to sense an external force applied to the image display apparatus; a memory configured to store at least one instruction; and a processor configured to execute the at least one instruction stored in the memory to activate the imaging device and control the display to display an external image captured by the imaging device in response to the external force being sensed while the image display apparatus is operating in a virtual reality mode of displaying a 360° image.
