This is a very small study on virtual social touch and copresence.
Using visual and auditory channels to simulate social touch sensations that enhance the sense of virtual social copresence is a question that has just been initially explored.
In this project, I designed and implemented a socializing experience delivered only through screen-mediated virtual touch. Further experiments with 12 people explored the effects of anonymity, the presence/lacking of a user avatar, and visual augmentation of co-touching on their sense of copresence.
None for now. But the code might be useful in the future.
