There are only so many degrees of freedom for users inside of these apps, which makes them simple to use. But this simplicity also strips away so much of the freedom we have during in-person interactions. You can type any message, but typing a message is all you can do. You can call any person, but talking directly into your camera is all you can do once you're connected. Without spatial interfaces, our current software doesn't give us much expressive control.

In social applications, spatial software has at least three advantages. These three advantages often overlap and bleed into each other.Afforded Intuition: Our natural understanding of space makes spatial software easier to use.Expressiveness: In a spatial interface, more degrees of freedom mean users can interact more creatively with software and with each other.Presence: In many spatial interfaces, we can sense other users through the presence of an avatar or figure.
