The mobile phone has become a repository for many of the things that make us who we are. The mobile phone is where we play games with fellow enthusiasts, comment on our favourite musical acts, access our bank accounts, stay in touch with and remain visible to our network of friends, assess self-tracking information through step counters, pulse meters and sleep apps. We might even answer work e-mails when on the go. Real-world encounters draw in our mobile phones as we use WhatsApp and GPS tracking to locate each other in crowded spaces or engage with the evermore prominent Internet of Things and Augmented Reality.
