the rise of mobile phones has put telecommunications right into the hands of users, but it has also
decreased the amount of phone booths in public spaces. comet is a mobile phone booth that allows users
to make private calls in public space. the project was created by a group of students in the interaction
design programme at the danish design school. the device itself utilizes an old hairdryer, that would be
more appropriate in a hair parlour, as the head piece. with some arduino circuits hacked onto to it and
an old office chair to sit on, the helmet enables users to make phone calls. the user sits in the chair and
inserts their head into the helmet. they type the number they are trying to reach on the dial pad and the
call begins. inside the helmet a microphone picks up the user’s voice and speakers project the voice on
the other end. the whole unit is mobile and can be moved around in the public space, for use by multiple
users.
