She works with animation and interactive video-installation,[4] digital art in public space as site-specific artworks[5] and Projection mapping,[6] video sculpture,[7] art-applications and Widget (GUI)[8] for mobile platforms.

In 1996, Passa began her work in animation and video-installation, which has been described as a constant study of the figure, geometric and essential, combined with a three-dimensional and dynamic vision of the virtual space.

[9] In 1999, Passa coined the term "Super Place"[10] as a reference for "Extens(z)ion Projects" and later for "Live Architectures" - a series of digital artworks developed over time and based on the concept of "super place" where the site is self-performing and moves beyond its capabilities, reflecting on the idea of the virtual/unreal and how human bodies, in real space, are related to this kind of dimension/experience.

[11] Passa's artistic research mainly explores architecture as interface, for example in the virtual reality series "Dimensioning" that aims to create a multi-dimensional extension of the space, allowing visitors to navigate into a moving 360° area.

[1] The net-art series "Extemporary Land Art on Google Earth"[12] aims to create an extemporary-temporary virtual land-art through augmented reality technology, constructing and re-constructing a sort of "mise en abyme" or "droste effect" in which an element shifts the other in depth.
