Owo vest allows users to feel physical sensations during metaverse experiences such as virtual reality games, including wind, gunfire or punching, at the Consumer Electronics Show (CES) in Las Vegas, Nevada, United States.

The CES tech show threw open its doors Wednesday in Las Vegas despite surging Covid-19 cases in the United States, as one of the world's largest trade fairs tried to get back to business.
