The idea is simple – so simple it was already applied elsewhere. The idea is to provide feedback about the quality of the way people brush their teeth. The Brushduino focuses on entertaining kids to keep them brushing at the right place for the right amount of time. Other projects (with many variants) focus specifically on time spent brushing.
I think embedded projects can go an extra mile (provided they are small enough). You can embark a gyroscope and take into account the types and amount of movements you make while brushing your teeth. This way you also have the time you did it anyway. The toothbrush could communicate with a computer to transmit the data. I guess being offline would save some space at the price of direct feedback. This direct feedback could also come in a simplified way, a bit like the Nike+ Fuelband does: it is not an exact measure that you need but merely the fact you brushed vigorously enough and during enough time. The way a gyroscope work should give the space covered – indirectly if you covered every teeth (to be checked). Connection of the toothbrush to a smartphone or a computer could provide the numerical data as well as some social features (as long as you think brushing your teeth can be something shared with your friends).
In terms of design it could look simply like this:
This kind of device will not replace advices given by dentists. But it can help / accompany people during their daily activities.
There are a few days left to vote for the Internet of Things Awards 2011. Initially I thought it was a very good thing, with lots of nice ideas for the future. But then I felt something was missing, imho of course: practical projects that will help the remaining 5 billion people who are not affected by that internet of things as it currently is. Let me explain …
I was thus happy to have a look at contestants in Postcapes’ Internet of Things Awards 2011. In this competition you have several categories like consumer products, networked art, entreprise implementation, self tracking products ; but I was also very pleased to see they included wilder categories like DIY projects, open source projects and environmental implementation. The inclusion of such diverse categories with a huge diversity of projects also shows that people (human beings) are still searching, discovering and defining what is and what will be the Internet of Things. At the most literal level, projects shown contain objects (things) connected to the internet/web and sending their status or responding to simple commands (a kind of home automation connected to the internet): BIKN tags, the Little Printer, Botanicalls, Twine, and all kinds of remote sensors to keep track of a fleet of vending machines, trucks, pallets, packages, etc. In my opinion, I categorize these projects as “a network of things for itself”: these things are created for themselves and can survive within their own world; they add data to the real world but this data still need to be processed to form information and to be relevant enough to create additional knowledge.
Don’t get me wrong, I know the field is still in its early infancy. In its Hype Cycle for Emerging Technologies of 2011, Gartner locates the Internet of Things on the increasing side of the expectation curve and gives it 5 to 10 years to be adopted globally. The fact DIY projects and prototyping/hobby boards like the Arduino are present in the contestant list also show that. These are first-generation products, lots of customization are needed as well as refinement of their uses. But early adopters are already investigating the field. And this diversity of directions is really good to explore all possibilities the connectivity of objects would allow.
This phase of early development also means that practical projects are currently targeting improvement of the occidental life style and sometimes tackle issues related to increased wealth and development (like the Nike+, the Jawbone UP, the Zeo sleep manager for sedentary and stressful lives). Some projects are even targeting the increasing isolation of people in occidental worlds not really by increasing their interaction with each other thru technology but by making them happy being alone. Watch for instance the following video (from Ericsson in category design fiction)!
In general, very few of these projects are aiming to help the remaining 5 billion people who are not affected by that internet of things as it currently is. The only project in this contest that could help less wealthy people is the SolarSinter project (also in category design fiction). Here, Markus Kayser uses sunlight and sand as raw energy and material to produce glass objects using a 3D printing process. He tested his device in the Egyptian desert where sunlight and sand are abundant. This could be used as small manufacturing devices to satisfy local needs when they occur.
In addition to the purpose of these devices, there is also the question of the infrastructure needed behind. For instance, Vietnam is very well equipped and connected (relative to its standard of living).
But we didn’t mentioned that some infrastructure are still switched on manually, like this public light bulb in the picture below.
So the Internet of Things is definitely something to watch in the coming years. I will be also waiting for new technologies and solutions that will actually help most of people and overcome their specific issues 🙂
