The term Metaverse was introduced in 1992. Lately, the concept has become a popular buzzword in the general public, thanks to Meta. And yet, its intrinsic reliance on the convergence between enabling technologies such as virtual reality, the internet, and social networks cannot be understated. It might prove a powerful tool for enhancing data discovery and interpretation, especially considering a collaborative setup. The work presented here aims to investigate the interaction between a real user and digital objects in a virtual world to understand which aspects of attention must be focused on to obtain a natural and comfortable use. Our work involved the generation of Metaballs and the interaction with them by a user in a virtual environment. Metaballs are particular implicit surfaces of arbitrary typology, widely used in Computer Graphics to model curved objects. The ”organic” look and feel of how they interact with each other and their resemblance to soft tissues have proved a natural fit for tasks such as surgery simulation. Still, these implicit surfaces can represent even real objects at an even smaller scale, like cells of living organisms, and the ability to comfortably interact with this supersized version of real objects could open the door to new possibilities.
