6.9 The personalised home

In the extract from The Road Ahead, quoted at the beginning of this section, Gates makes reference to 'an electronic pin to clip to your clothes'. This pin appears to have the ability to communicate to the network so that its wearer can be identified and located. The information can then be used to provide a personal environment for the wearer. The next section introduces you to a technology that can provide the kind of pin that Gates refers to.
