Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual reality (VR) users often experience sickness due to the mismatch between virtual motion and lack of actual motion, which affects their vestibular system, leading to discomfort and disorientation.
Innovation Solution
A video display apparatus that includes a processor to analyze video content and generate signals for an electrical stimulation apparatus, which applies controlled electrical stimuli to the user based on the motion depicted in the video, helping to synchronize the virtual experience with the user's vestibular system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical stimulation is applied to enhance virtual motion perception, then user immersion and sense of reality are improved, but device complexity increases
Solution Approach 1:
The patent combines the video display apparatus with the electrical stimulation apparatus into a single integrated system. The processor generates control signals based on video motion data, and the communication unit transmits these signals to the stimulation apparatus, merging visual and tactile stimulation functions into one coordinated device that enhances immersion without requiring completely separate systems
Solution Approach 2:
The processor acts as an intermediary that analyzes video motion data and converts it into appropriate electrical stimulation signals. This mediator translates visual motion information into tactile feedback that synchronizes with the virtual reality experience, bridging the gap between visual input and physical sensation
2Object-affected harmful factors
If electrical stimulation is applied to reduce VR sickness, then user comfort is improved, but energy consumption increases
Solution Approach 1:
The electrical stimulation is applied periodically and selectively based on motion detection in the video content. The processor analyzes video frames to identify motion events, and the stimulation apparatus activates only during these specific moments rather than continuously, reducing overall energy consumption while maintaining effectiveness in combating VR sickness during relevant visual stimuli
Solution Approach 2:
The system dynamically adjusts stimulation parameters such as intensity, frequency, and duration based on the motion characteristics detected in the video. By varying these parameters according to the severity and type of motion, the system optimizes energy consumption by applying stronger stimulation only when necessary and using minimal stimulation for subtle motions
