Virtual glasses regulate oxygen supply Science


In the virtual world, you step from a stuffy interior to a fresh outdoor space. The lungs fill with fresh air and oxygen levels rise.

A vision can sound special if you are used to virtual realities based on sound and image. Soon, however, it may be a reality if the virtual mask developed by the Salzburg University of Applied Sciences gets down.

Professor Markus Tatzgernin and built by his group masks regulates the user’s oxygen intake and measures breathing to create a better experience. Thus, for example, moving from one state to another could affect the kind of air a person gets to breathe.

The idea of ​​a virtual mask measuring respiration is not new. However, previous applications have relied on breathing sounds measured by microphones or sensors that measure chest movements, and have not worked very accurately.

The Tatzgern group took a different approach. Their mask includes a respirator-like part that measures human breathing and regulates oxygen supply.

In this way, the mask can be used to improve the authenticity of the virtual experience. For example, breathing may be difficult when the character encounters smoke or fire.

With the help of a mask, the virtual experience also becomes even more interactive.

For example, lifting a heavy object could feel like difficulty breathing.

When the user blows a virtual balloon, he may feel resistance during the blowing phase, while the inhalation remains light.

The measurement of outward breathing, in turn, allows for breath-based interaction, such as playing a virtual harmonica.

An oxygen control mask can even sound distressing. What if, for example, you sink underwater in a virtual world? Will the oxygen supply be cut off?

This is not possible, Tatzgern assures.

“Under no circumstances do we want to harm users. The mask never supports oxygen intake, ”Tatzgern writes in his email reply.

Instead, it can help equalize respiration in applications such as therapy. For example, if a mask notices that the user is breathing or breathing intermittently, it can balance the situation by giving more oxygen.
