On your way home from work, you receive an MMS from your significant other. There’s grocery shopping to be done!
“Don’t forget to buy sugar, milk and that stationery I mentioned earlier,” says the message.
Your car’s LCD display plays back the video message, uses primitive AI to understand keywords such as ‘buy’, ‘sugar’, ‘milk’, and ‘stationery’. It then automatically charts the ideal route to the nearest and cheapest supermarket where all the items on the list are available.
Payment
Once you have picked up all the necessary items, you head to an automated, tag-reading checkout counter. 
The total is beamed to your WiMAX-enabled watch, which connects to your bank account, verifies that you have sufficient funds, and then makes a secure wireless payment.
Communications
Just as you are exiting the supermarket, your wrist begins to tingle-your watch shows you that your spouse is calling. You say “accept call”, and the call is patched to your WiFi-enabled spectacles. 
You assure her that you have not forgotten anything, only because technology wouldn’t let you-the stupid watch kept sending reminders in that silly robotic voice to your spectacles’ earpiece, informing you that the stationery department was the nearest to your current location, and was a priority.
Once you are done with the call, you tap your wristwatch face to end the call.
Photography And Imaging
On your way home, you see an interesting advertisement. With a click of a button on your spectacles, you capture an image of exactly what you are seeing. 
The image is sent to your watch, which OCRs the image, extracts the contact details and saves it in your address book.
Global Positioning
Using WiMAX, your car contacts your home and informs it that you are just 10 minutes away. 
Your house sends a notification (like an MSN Messenger popup) to your spouse who is watching a cooking show, and your kids, who are playing a game on their portable 60-inch wireless LCD.
The kids inform the robot helpers to start clearing their room, while your spouse decides to start preparing dinner.
Your wife clicks a button on the TV to save a few recipes that were shown on the cooking show. The TV communicates with the fridge to tell it the ingredients of the recipes. The fridge informs you, via its LCD display, that you only have the requisite ingredients for three of the recipes.
The fridge also offers useful information, such as how many times in the past year the three recipes have been prepared, and how much each was liked by the individual members of the family-by requesting the dishwasher to provide data on how much each family member wasted, etc.
Your spouse chooses the dish that hasn’t been prepared for the longest period, so as to keep the menu fresh, and starts to make dinner.
Gaming
The family sits down to have dinner, but kids will be kids. They have wirelessly transferred all their game data from their console to handheld gaming devices. No longer are games platform- dependent, and all game data can be transferred from any gaming device to another. 
Needless to say, this is one technology enhancement that your spouse is not pleased with! A few yells and some threatening remarks involving a ban on gaming devices and a year’s pocket money later, dinner is a little more orderly and peaceful.
RFID
Once dinner is done, you decide to request a classic movie from your favourite digital movie-on-demand channel provider-the family’s favourite pastime. However, it’s very hard to do so without the remote. Sigh! The kids again. Funny how they can remember how you promised to take them on a camping trip a few years ago, but can’t remember what they did with a remote that they were using less than an hour ago. 
Time to ask good old house find it. You log into the house’s control panel, it authenticates you using a retina scan and voice recognition, and then promptly answers your question. It shows you a graphical representation of where the remote is-dropped and then perhaps kicked under the sofa. How do the kids manage such feats?
Smart Homes
While your family is enjoying the movie, your house automatically switches into your predefined ‘Movie Mode’. It automatically lowers the ambient lighting by 70 per cent, rejects all phone calls from numbers of less than ‘Level Three’ importance, and turns off all communication notifications to your family. 
This level also has increased security, as all members of the family are engrossed. Doors and windows are locked automatically, and the security alarm is activated to prevent unauthorised entry to the house or garage.
Data Syncing
As you head off to sleep, you place your watch in its cradle, where it is charged and transfers all newly recorded data, such as contact information and updated schedules, to the house computer. This will help the house decide what time to wake you tomorrow and also what you might need for work. 
The kids, meanwhile, have carried the wireless LCD into their room, and are continuing their game from where they left off. You tell the house to cut off power supply and connectivity to the LCD in half an hour and go off to sleep; your kids mutter their disapproval, but value their allowances too much to actually complain.
Security
While the neighbourhood sleeps, your house is on full alert. A passing police car broadcasts its encrypted ID, which your house recognises as the trusted neighbourhood watch, and sends the patrol car the all-clear signal. The neighbouring houses do the same. Life is just too hard for burglars, especially after physical money was stopped-everything’s electronic now.
The Technologies
Wireless: Everything uses WiFi or WiMAX to communicate-with high security and encryption. 
Tracking: Everything has an ID and can be tracked or traced easily.
Storage: No gadget needs a sizeable hard disk anymore. All devices can share each others’ storage as well as centralised storage.
Bandwidth: With advancements in wireless technologies, there is no more bandwidth crunch and no more messy cable laying; bandwidth is cheap.
AI: Artificial Intelligence is limited, but capable of handling mundane tasks, and is self-learning.
Networks: Networks are global and ad hoc, but secured with high encryption.
