The mobile phone has changed the way people communicate, but a consortium of Japanese researchers and companies are banking on the device to do much more.
The P2P Universal Computing Consortium (PUCC) has developed a set of networking standards that allow mobiles to remotely control domestic appliances from afar.
At CES the consortium showed off an iPhone application that allowed a user to control a flat in Tokyo.
The user could switch lights on and off, control the air conditioning and even turn the washing machine on.
The technology is already available in Japan where users of the NTT DoCoMo network can keep an eye on their home from afar.
The consortium has also shown off healthcare applications including a wireless nappy for use by bedridden patients and a heart monitor that allows a doctor to monitor a patient from afar.
Later this year the group will release software that will allow anybody to build applications using the standards.
