Water Tank VR System Using Stereoscopic Wall Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality (VR) technologies do not allow users to experience VR spaces while feeling as if they are floating, limiting the immersive experience.
Innovation Solution
An image processing system that includes a water storage space with projecting devices displaying stereoscopic view images on the walls, allowing users to wear goggles with a liquid crystal shutter for a floating VR experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stereoscopic view images are displayed on wall surfaces in a conventional VR setup, then users can experience immersive virtual reality, but users cannot experience the feeling of floating in the VR space
Solution Approach 1:
The patent introduces a water tank dimension into the conventional VR setup, allowing users to physically float in water while viewing stereoscopic images. This adds a physical floating dimension to the virtual reality experience, enabling users to feel as if they are floating in the VR space by combining water buoyancy with stereoscopic visualization.
2Duration of action of moving object
If users perform prolonged swimming exercises, then physical fitness is improved, but user motivation decreases over time
Solution Approach 1:
The system provides real-time visual feedback by displaying stereoscopic images of underwater environments, marine life, and exercise-related information in the user's field of view. This immersive visual feedback maintains user engagement and motivation during prolonged exercise sessions by making the workout experience more engaging and less monotonous.
3Illumination intensity
If conventional VR headsets are used, then immersive visualization is achieved, but users cannot experience natural floating sensation
Solution Approach 1:
The patent replaces the mechanical constraint of head-mounted displays with a more natural system where users wear simple goggles and float in water. The stereoscopic images are projected onto the water tank walls, eliminating the need for heavy VR headsets and allowing users to experience both visual immersion and natural floating sensation simultaneously.
Applied Scientific Principles
