Glass is just one of several technologies that will allow us to interact with computers more naturally in the near future. Machines that can understand our speech and gestures are also becoming an everyday reality (see “Hands up! Do you speak digital body language?”). Rather than checking in with our phones, omnipresent computers will check in on us. This is the next step in the evolution that has already taken us from mainframes to desktops to tablets. It seems the age of ubiquitous computing, or “ubicomp”, is upon us.
