Physical browsing is a new method for providing direct access to services without the use of complicated menus or inputting long addresses; all the user needs to do is touch an object with a mobile terminal (such as a mobile phone) or point the terminal at the object. A child can call ‘Granny’ by pointing a mobile phone at the grandmother’s photo; a teenager can order a new ringing tone by placing the phone on the tone in a newspaper advertisement; a door can be opened by touching it with a mobile phone. VTT Technical Research Centre of Finland has developed a technology that enables physical browsing, has as well studied the usability and the opportunities the technology offers.
Physical browsing is based on the use of identifiers, or tags, and mobile communicators. Together, tags and the readers installed in mobile communicators make it possible to produce and use novel kinds of information related to objects and ambient space. They transform our physical environment into a website, whose links provide access to electronic information or services related to our environment. Physical browsing is an easy and agreeable way to employ IT applications irrespective of time and place. With the ‘point, touch’ method, the opening of WAP (Wireless Application Protocol) pages is significantly (up to two or three times) faster than entering the WAP address manually.
The tags may be optical, such as bar codes used in commerce, or more advanced matrix codes, which can be read with a camera phone, for example. Infrared links may also be used to transfer tag information. RFID tags based on radio frequencies, and high-frequency remote tags are a rapidly growing field. Current research subjects include remote sensors, which not only provide measurable information about the object but also enable new kinds of interfaces. Near Field Communication (NFC), short-range touch-free communication technology based on radio frequencies, will also be applied in mobile phones in the future. All these technologies may also be used to open device-to-device connections, continuing the communication through Bluetooth or WLAN network, for example.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
