Putting sensors and actuators in everything from homes and cars to shoes and coffee cups promises to make our daily lives easier, safer and more efficient. But such 'ambient intelligence' requires a merger of the virtual and digital worlds. EU-funded researchers in the Sensei project are bridging the gap and their results are already leading to 'smart cities' being set up all over Europe.

'Today, the internet world is a virtual world of data mostly stored and accessed from servers,' says Dr Hérault. In the future, we will have an 'Internet of things' in which a multitude of things in the real, physical world will be digitised continuously: in many situations, we won't just be asking web servers for data, we will be asking sensors in everyday objects for data, he suggests. 'We need to understand how best to interconnect the real world and the virtual world.' 

An open service interface that uses semantic information to process data means that information is accessible and understandable to both humans and machines.  'You could ask, for example, "What is the temperature on Oxford Street?" The system would decode that semantic information, access sensor networks on Oxford Street that have temperature sensors, check the reliability of each network with regard to information quality, and return an answer,' Dr Hérault explains. 

Perhaps you’ve recently read about the Tampa Bay Lightning’s innovative chip-embedded jerseys. Blending physical gamification techniques such as a special badge to denote a certain level of status – in this case a season ticket holder – and embedded chip technology in the patch that issues those donning the jersey automatic discounts on concessions and merchandise while at the arena, the Lightning have a bona fide innovation hit on their hands. As a marketing ploy, you can not argue with the success of this experiment. As a technological innovation, what you see here – a piece of connected clothing – is just a rudimentary beginning of Web 3.0.

Apple (Nasdaq: AAPL  ) filed a patent at the tail end of 2009 dubbed "Local Device Awareness," which describes automated connections between a number of close-range devices. Some potential applications could be device position targeting (think locating your keys) or proximity-based gaming.

If Apple's patent seems overly broad, patent hoarder InterDigital (Nasdaq: IDCC  ) has gone for specificity. It holds some 33 known patents covering machine-to-machine communication.

Motorola and Google seem to be behind in patents, with only one highly technical machine-to-machine patent showing up for Motorola Mobility, and none for Google. But as you'll soon see, the two companies might be hoping for a more open environment.

The first of these changes is BYOD (Bring Your Own Device) computing. BYOD is a much better term than “consumerization” and really portrays the meaning that many of us are buying smart phones, tablets or laptops to use them on a work network. The tension this creates is predictable.

In 2012 and beyond, we’re going to see more and more different devices coming into the workplace.

If you use PayPass, Tap & Go, or other contactless credit cards, that’s NFC. In fact, NFC hardware already is appearing in smart phones and tablets. There are relatively few devices with NFC today, but there will be more in 2012.

The battle is not just about dividing up territories already occupied; it is also about finding new lands to conquer. Both firms are keen to stake claims on the largely uncolonised and still somewhat notional terrain known as the “internet of things”: the myriad processors in industrial machinery, consumer goods and infrastructure, ever more of which will communicate with each other and with distant computers. Cisco, a giant American maker of networking gear, estimates that by 2015 there may be almost 15 billion internet-connected devices, up from 7.5 billion in 2010. Whereas the market for more phones and other personal computing devices is limited by the number of persons the planet has to offer, things, being more numerous than people, provide a lot more long-term room for growth.

Just what might be possible is hinted at in this fascinating post by Andrew Fisher, entitled "Towards a sensor commons": For me the Sensor Commons is a future state whereby we have data available to us, in real time, from a multitude of sensors that are relatively similar in design and method of data acquisition and that data is freely available whether as a data set or by API to use in whatever fashion they like. My definition is not just about “lots of data from lots of sensors” – there is a subtlety to it implied by the “relatively similar in design and method of data acquisition” statement. In order to be useful, we need to ensure we can compare data relatively faithfully across multiple sensors. This doesn’t need to be perfect, nor do they all need to be calibrated together, we simply need to ensure that they are “more or less” recording the same thing with similar levels of precision and consistency. Ultimately in a lot of instances we care about trended data rather than individual points so this isn’t a big problem so long as an individual sensor is relatively consistent and there isn’t ridiculous variation between sensors if they were put in the same conditions.

What this boils down to, then, is trends in freely-available real-time data from multiple sensors: it's about being able to watch the world change across some geographical area of interest -- even a small one -- and drawing conclusions from those changes. That's clearly a huge step up from checking what's in your fridge, and potentially has major political ramifications (unlike the contents of your fridge).

Become dispersible

Graham Fisher, a Director at Cambridge Wireless, welcomed the efforts made by the Technology Strategy Board.  He told TechEye that there are plenty of opportunities to be had with an Internet of Things, though there is more that needs to be done in terms of infrastructure in order to create the ecosystem the TSB is striving for. “Rural connectivity could be an issue as it is necessary that ubiquitous internet is available in order to create efficient systems,” Fisher told TechEye. “For efficient telehealth and smart metering this all falls down if you are not able to provide ubiquitous connections.” Then again, there are "problems with a lack of full connections in many parts of the country,” Fisher says. “We need to push forward with the roll out of LTE and use of white spaces as soon as possible to support this.”

He is officially called the "Messaging Community Lead" for IBM's WebSphere message queue (MQ) architecture, which is a title that grants some modicum of honor without claiming too much authority. Andy Piper has become IBM's point man for the concept of a planet enmeshed in billions, perhaps trillions, of signal-sending, communicating devices. The case may be made that anything that can be "on" could be made to send a signal on a network - perhaps something as simple as "on" itself, periodically. The possibilities for a world where the operating status of any electronic device may be measured from any point on the globe, are astounding.

Two weeks ago, IBM and its development partner Eurotech formally submitted Message Queue Telemetry Transport protocol to the Eclipse Foundation open source group. It's being called "the" Internet of Things (IoT) protocol, but in fairness it's only one candidate. It would serve as the communications mechanism for devices whose size may scale down to the very small level, with negligible power and transmission radius of only a few feet.

One example application already in the field, Piper told RWW, is in pacemakers. Tiny transmitters inside pacemakers communicate using MQTT with message queue brokers at their patients' bedsides. Those brokers then communicate with upstream servers using more conventional, sophisticated protocols such as WebSphere MQ.

Why are embedded systems important right now? Elecia White: Embedded systems are where the software meets the physical world. As we put tiny computers into all sorts of systems (door locks, airplanes, pacemakers), how we implement the software is truly, terrifyingly important. Writing software for these things is more difficult than computer software because the systems have so few resources. Instead of building better software, the trend has been to allow a cowboy mentality of just getting it done. We can do better than that. We must do better than that.

What's on the horizon for embedded systems? Elecia White: Jewelry that monitors vital signs. Credit cards that only work when we touch them. Smart dust and nanobots. Personalized learning. Self-driving cars. Science fiction isn't so far away from fact.

If this is progress, what will 2031 be like? The very goal of embedded systems is to distribute the intelligence from a centralized computer to a smaller widget that can live in your home, on a satellite, in a car, or in your pocket. If a big desktop computer from 2011 can fit in our 2031 pockets, does that mean our smartphones will fit into an earring or disposable microdot?

Take a moment and imagine a future where every object you own has a presence on the internet. Your car would have a Facebook status (“just hit 3,000 miles, need an oil change”), your shoes would appear on Google Maps, even your toothpaste would tweet (@shoppinglist you’ll need more of me soon).
