Despite the existence of answer phones and  voice mail, a ringing phone remains impossible to ignore. Whether we are having  a private conversation, snowed under with work, or just not in the mood to  speak to anyone, the phone keeps ringing. 
        Current mobile  communication devices do not grab our attention in a socially appropriate way.  They could be disrespectful of ongoing social activity such as an important  meeting or private dinner. To improve on this, IT research student Stefan Marti may have the  answer: ditch your mobile phone, and get a squirrel.  He has built the Cellular Squirrel, a  system where the agent that controls your cell phone is embodied in a small  portable animatronic device, as a personal 'companion' for the user. This embodiment is able to use the same subtle but still public non-verbal cues to  get our attention and interrupt us like humans would do such as eye gaze,  posture and small gestures. The user can whisper and listen to their squirrel,  receiving and replying to voice instant messages.  
Currently, the squirrel prototype needs to  communicate with a computer and so is tied to a physical location, but there is  no reason why the technology could not eventually fit into something the size  of a mobile phone. 
Today's cell phones  are passive communication portals. They do not 'care' about our ongoing  conversations, about the relationship between caller and callee, nor what the  purpose of the call is. It deals with incoming communication attempts when the  user cannot or does not want to be interrupted. The Cellular Squirrel is part  of a larger project that aims at adding elements of human style social  intelligence to our mobile communication devices in order to make them more  socially acceptable. It is an Autonomous Interactive Intermediary that assumes  the role of an actively mediating party between caller, user and co-located  people.
In previous incarnations, the device has been a  bunny and a parrot. The idea, says Mr Marti, is to dress the technology up as  something which we would be happy talking down to. The Intermediary is a  conversational as well as robotic agent. 
        An Intermediary,  however, is more than just an interactive animatronic device that listens to  you and whispers into your ear. When a call comes in, it detects face-to-face  conversations to determine social groupings, may invite vetoes from the  co-located people, consults memory of previous interactions stored in the  location, and tries to asses the importance of the incoming communication by conversing  with the caller. 
        The current implementation of the  Cellular Squirrel is a remote brain robot. It is controlled by a PC with a  Bluetooth dongle that runs all the necessary control processes (conversational  agent, speech recognition, animatronics control server, etc). But Mr Marti argues that there are still  technologies which hardly need to be improved, such as the lift.
