VR Content Adaptation via Biometric Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality systems fail to provide personalized experiences as they do not consider individual user reactions, leading to inconsistent and potentially uncomfortable experiences for multiple users.
Innovation Solution
A system comprising VR content playing devices, sensors to measure biometric information, and a control unit that calculates reaction values and adjusts VR content properties in real-time to optimize the experience for each user, allowing users to control content with body gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual reality contents are provided to multiple users using the same system, then the system can serve multiple users, but all users receive identical images and motions which do not account for individual user reactions
Solution Approach 1:
The system incorporates sensors that continuously monitor user biometric information (heart rate, temperature, galvanic skin response) and provides this feedback to the control unit. The control unit processes this feedback and dynamically adjusts VR content properties in real-time, creating a closed-loop system that adapts to individual user reactions while maintaining system reusability across multiple users
Solution Approach 2:
The system transitions from static, pre-programmed VR content delivery to dynamic, real-time content adaptation. The control unit continuously modifies content properties based on current user biometric states, allowing the same physical system to provide personalized experiences to different users without requiring separate systems for each user
2Adaptability or versatility
If biometric sensors and real-time processing are added to analyze user reactions, then personalized VR content can be provided, but the device complexity and cost increase
Solution Approach 1:
The control unit serves multiple functions: it manages VR content playback, processes biometric sensor data, calculates reaction values, determines appropriate content adjustments, and controls content delivery. This multi-functional design consolidates what could be separate complex subsystems into a single coordinating unit, reducing overall system complexity while maintaining content adaptation capability
Solution Approach 2:
Instead of fundamentally changing the system architecture, the invention achieves personalization by adjusting content parameters (images, motions, properties) based on biometric input. This approach allows adaptation through parameter modification rather than structural complexity, as the same physical system delivers different content configurations based on real-time user state analysis

AI summary
There is provided a virtual reality (VR) contents providing system. The system includes a storage unit, a VR contents playing device, a sensor and a control unit. The storage unit stores a plurality of VR contents. The VR contents playing device provides a VR content among the VR contents. The sensor measures biometric information of a user of the VR contents playing device. The control unit is configured to receive the biometric information from the sensor, calculate reaction value for the user based on the biometric information every predetermined time interval, determine property information for a VR content to be played based on the reaction value, and control the VR contents playing device to play its VR content having the determined property information.
