Head Mounted Display immersed within the aquarium environment
PANAquarium is a project carried out at University of Southern California:
This collaboration between IMSC and USC School of Fine Art, involved building a circular fish tank around a panoramic camera with live tropical fish swimming within and a coral reef photo serving as background on the outermost tank wall. The users wore an Head Mounted Display, immersing them within the aquarium environment.
Following the aquarium immersion, the coral reef photo background was manually removed to reveal the background activity through the glass which then "breaks of the illusion" for the user. This application serves as test for a future version in which the panoramic camera will be placed within a sealed plexiglass tube and lowered into a very large commercial aquarium exhibit.
Connected pasta there is this Swim goggles with heads-up display that seems to be way better!
