With the arrival of mobile phones, the concept of calling has moved from calling a place to calling a person, which has quite distinctive affordances. Frontdesk proposes a place-based communication tool that is accessed primarily through any mobile device and features voice calls and text chat. The application uses �place� loosely to define a physical space created by a group of people that have a shared context of that place. Examples of places could be different parts of a workspace in a physical building, such as the machine shop, caf�, or Speech + Mobility group area at the Media Lab. When a user calls any of these places, frontdesk routes their call to all people that are �checked-in� to that place.
