Welcome to the Homes of the Future online website. I will be your virtual guide around the homes you could soon be living in. Let’s begin our tour in the bedroom. Firstly, the bed is programmed to gently rock you awake in the mornings. There’ll be no more rude awakening by an alarm clock, and it will also know what time you need to wake up as it will get that information directly from your Personal Digital assistant, that is, your PDA, which will be inserted into you.
Let’s move to the wardrobe. Those are your musical shoes that generate music while you walk. The music will change according to how fast you’re walking; calm music for a relaxing stroll and faster beats for when you’re in a hurry. You’ll feel like you’re walking on air. What’s more, your clothes are also intelligent. They sense how you’re feeling and then change colour. The fabric that they’re made of also converts your body heat into a low voltage electricity generator for some of the gadgets that are now inside you, like your PDA, for example.
Moving on to the bathroom... So, after waking up, you need a shower. There’s no need to turn on any taps as the house will know exactly what temperature you like the water in the mornings, though you’ll still have to wash yourself!
From the bathroom, we move into the kitchen. Now, we’ve all had that horrible feeling when you can’t find your keys just as you’re about to go out. Well, in the home of the future you wouldn’t need to panic, all you need to do is an Internet search. All items are now programmed with a tracking device so that they will light up and signal to you where they are. Just in case the object is upstairs, the house will project its position on your fridge.
Speaking of your fridge, this is now as intelligent as your clothes. Not only does it keep a record of when you’re running low on everyday essentials like milk, but it emails your local grocery store, which will deliver them for you. It can also help with planning meals if you have friends over for dinner by moving the chicken from the freezer so that it’ll thaw in time.
