Visiting Bill Gates
When you have guests, you often want to go out of your way to keep them comfortable and entertained. You might stock up the fridge and tidy the house as a welcoming gesture. But for billionaires like Microsoft’s founder Bill Gates, technology can do all the catering. When visitors arrive at his house, they can enter their temperature and lighting preferences into a device. They are then provided with a pin which tracks them as they navigate the different rooms. The house’s sensors track their movement, and the internal climate adapts for them.
There are also speakers placed in the walls, so if you want music playing while you’re there, the sound can follow you as you walk through the mansion.
In terms of internal decoration, Gates’ home is set to please the eye of any guest, as you can choose your own artwork. $80,000 (£58,000) worth of screens covering the walls allow guests to select any digital art or photograph and project it in an instant.

Bill Gates’ home in Medina, Washington, is worth at least $127 million (£92.6 million)
