The broad goal is to become the emotion layer of the Internet says Affectiva cofounder Rana el Kaliouby a former MIT postdoc who invented the technology.
In using Affdex Affectiva recruits participants to watch advertisements in front of their computer webcams tablets and smartphones.
Still in their early stages some of the apps are designed for entertainment such as people submitting selfies to analyze their moods and sharing them across social media.
and provide real-time feedback to the wearer via a Bluetooth headset. For instance auditory cues would provide feedback such as This person is bored
One of Affectiva s long-term goals is to usher in a mood-aware Internet to improve users experiences.
Imagine an Internet that s like walking into a large outlet store with sales representatives el Kaliouby says.
Websites and connected devices of the future should be like this very mood-aware. Sometime in the future this could mean computer games that adapt in difficulty and other game variables based on user reaction.
This approach could lead to devices to charge cellphones or other electronics using just the humidity in the air.
For example Miljkovic has calculated that at 1 microwatt per square centimeter a cube measuring about 50 centimeters on a side about the size of a typical camping cooler could be sufficient to fully charge a cellphone in about 12 hours.
Near the end of the last decade however a team of MIT researchers led by Professor of Physics Marin Soljacic took definitive steps toward more practical wireless charging.
We believe wireless charging has a potential to do that. He is not alone. Last month Witricity signed a licensing agreement with Intel to integrate Witricity technology into computing devices powered by Intel.
Witricity Corp. recently unveiled a design for a smartphone and wireless charger powered by its technology.
The charger can charge two phones simultaneously and can be placed on top of a table or mounted underneath a table or desk.

Frustrated and standing half awake he contemplated ways to harness power from all around to charge the phone.
At the time he was working on various photonics projects lasers solar cells and optical fiber that all involved a phenomenon called resonant coupling.
Wireless charging: An expectationthese days Gruzen sees wireless charging as analogous to the evolution of a similar technology Wifi that he witnessed in the early 2000s as senior vice president of global notebook business at Hewlett packard.
At the time Wifi capabilities were implemented rarely into laptops; this didn t change#until companies began bringing Wireless internet access into hotel lobbies libraries airports and other public places.
Now having established a standard for wireless charging#of consumer devices with the A4wp (Alliance for Wireless Power) known as Rezence Witricity aims to be the driving force behind wireless charging.
Soon Gruzen says it will be an expectation much like Wifi. You can have a charging surface wherever you go from a kitchen counter to your workplace to airport lounge
and hotel lobbies he says. In this future you re not worried about carrying cords. Casual access to topping off power in your devices just becomes an expected thing.
This is where we re Going with an expected rise of wireless charging one promising future application Soljacic sees is in medical devices especially implanted ventricular assist devices (or heart pumps) that support blood flow.
Currently a patient who has experienced a heart attack or weakening of the heart has wires running from the implant to a charger
#Own your own data Cellphone metadata has been in the news quite a bit lately but the National security agency isn t the only organization that collects information about people s online behavior.
Newly downloaded cellphone apps routinely ask to access your location information your address book or other apps and of course websites like Amazon or Netflix track your browsing history in the interest of making personalized recommendations.
At the same time a host of recent studies have demonstrated that it s shockingly easy to identify unnamed individuals in supposedly anonymized data sets even ones containing millions of records.

For years, Li-Shiuan Peh, the Singapore Research Professor of Electrical engineering and Computer science at MIT, has argued that the massively multicore chips of the future will need to resemble little Internets,
where each core has associated an router, and data travels between cores in packets of fixed size.
Groups of declarations reach the routers associated with the cores at discrete intervals intervals corresponding to the time it takes to pass from one end of the shadow network to another.
Each router can thus tabulate exactly how many requests were issued during which interval, and by which other cores.
Core 32 router may receive core 10 request well before it receives core 1 . But it will hold it until it passed along 1. This hierarchical ordering simulates the chronological ordering of requests sent over a bus,

DIG is directed by Tim Berners-Lee the inventor of the Web and the 3com Founders Professor of Engineering at MIT and it shares office space with the World wide web Consortium (W3c) the organization also led by Berners-Lee that oversees the development of Web protocols like HTTP XML and CSS.
DIG s role is to develop new technologies that exploit those protocols. With HTTPA each item of private data would be assigned its own uniform resource identifier (URI) a key component of the Semantic web a new set of technologies championed by W3c that would convert the Web from essentially a collection of searchable
text files into a giant database. Remote access to a Web server would be controlled much the way it is now through passwords and encryption.
But every time the server transmitted a piece of sensitive data it would also send a description of the restrictions on the data s use.
It s not that difficult to transform an existing website into an HTTPA-aware website Seneviratne says.
But using standard Semantic web techniques it would mark that record as derived from the PCP s record

Using a smartphone camera equipped with a lens offering twentyfold magnification anyone could image the particles after shining near-infrared light on them with a laser pointer.
The researchers are also working on a smartphone app that would further process the images and reveal the exact composition of the particles.

#What exactly is Google's'cancer nanodetector'?'Last week US tech giants Google made a splash in the media announcing plans to develop new'disease-detecting magnetic nanoparticles'.
'This was welcomed almost universally after all trying to detect diseases earlier is something that's a focus of many research organisations including ours.

But then they're Google he says. They do things differently. The way traditional science works is to map out all the possible risks demonstrate you've accounted for them
Google are doing the opposite they're saying'we want to get to here we'll worry about the details later'.
Google have been similarly vague about the precise form of nanotechnology they aim to use Graham points out:

it seems according to this article in Wired that Gambhir originally advised Google about nanotechnology. What are the current challenges facing nanodetectors?
So for Google's biomonitor they need to work out how to keep the particles in the body
This is something Google really seem to have ducked in their announcement. We don't need to dwell on it too much
but there's been a lot in the press in the last year about who has access to Google's data and under
what circumstances says Graham referring to reports of Government agencies accessing user data from tech companies like Google and Facebook.
Professor Graham's'take-home'message is that it's a mistake to see Google as the only organisation focusing on nanotechnology to detect disease it's a vibrant active field with incredible potential but still in its early days.
