You get a second cup of coffee and decide to work for a while in the sunroom.

You tell the home controller where you are, and the controller transfers all your business calls to the extension near the table. Your laptop is wirelessly connected to your server and the Internet. You check your various e-mail accounts and voice mail and make a few conference calls on the multiline home-telephone system.

While you’re on one phone call, you turn on the TV to access the local online directory and navigate to the ordering page for that posh take-out shop down the street. Twenty minutes later, the delivery person arrives at the front door; you take your wireless two-line headset phone — conference call and all — to the door, where you tip the  delivery person (you paid over the TV set) and retreat back to the sunroom for lunch.

For a midafternoon break, you head for the exercise room to work off some of that lunch. When you enter, you announce yourself to your voice-activated home-automation system, and it automatically sets the music and other  environmental settings to your previously defined preferences. You sit down at your rowing machine, which has a large monitor that shows real-life settings of popular rowing locales.

Halfway through your workout session, a delivery person shows up at your door. An announcement that someone is at the door interrupts the music, and the nearest video display shows a picture of who it is. You don’t want to stop mid-workout, so you reply that you are busy and ask him to leave the package inside the door. You prompt for the control system to unlock the front door, and watch as the front door unlocks itself and the delivery person places the packages in the foyer. He leaves, and you start rowing again along Boston’s Charles River.

It’s your turn for a temperature-controlled shower, where you listen to CNN from the TV set, via moisture-resistant speakers mounted in the bath. Squeaky clean, you go back to work. At 3:00, you have your first videoconference of the day from your office downstairs. While in the basement, you call up your home-control system and start the roast cooking in the oven.

The kids drift home in the afternoon and spread out across the house. While you access your corporation’s data network, your kids take advantage of the computers. The youngest kids — twins — play multiplayer games on the home’s high-speed Internet connection. Your eldest daughter logs onto the school’s educational network to do research for the midterm paper due next week. And your son, when home from football practice, logs onto his school’s network to collaboratively work with three others on a joint presentation for the next day. Instant messages, e-mails, and file transfers all flow with ease.

The home controller’s voice enunciator reminds you that the roast should be done by now, and you head upstairs.
