ABSTRACT
This chapter provides the terms feltness, presence and co-presence with regards to mobile interaction and performance over the Internet and telecom networks. It also provides few different notions of liveness within human interaction, with special focus on real-time liveness in performance. Philip Auslander in his book Liveness states that presence has an emotional impact, is ephemeral and evanescent, 'an intangible expression that only exists in the transitory present moment. Presence is an embodied physical and/or virtual engagement of otherness and others elsewhere in time and/or space. Presence can be experienced as meeting or sending of one's extended body/consciousness or awareness of self, or other, via invisible, non-corporeal embodiment. Liveness is the experience of being intertwined simultaneously in time and/or space and physicality. The concept of liveness is enmeshed with presence, but is not of the same quality. Liveness in performance is also about 'real time'.
