Others - particularly parents, who already are tapping the new technology to keep tabs on their kids - view it as a convenient way to ensure their children's safety in an increasingly ominous world.
Regardless of who's right or wrong, one thing is certain: In the not-too-distant future, Location Based Services, or LBS, will become as ubiquitous as cell phones are today. And the new technology is expected to change the way we do business, interact with each other and navigate through our daily lives."Location Based Services are the new face of the wireless Internet,"
Kim, along with U. of I. postdoctoral fellow Sung-Gheel Jang, developed the protocol for the international standard for Geographic Information Systems, described by the U. of I. professor as "the backbone" of LBS. Earlier this year, the standard created by Kim and Jang was adopted and published by the International Organization for Standardization as ISO 19134.Kim said LBS, introduced on cell phones in Korea and Japan, and just becoming available in the U.S., function through a combination of GIS; information, positioning, and Intelligent Transportation Systems
(ITS) technologies; and the Internet.
"LBS combine hardware devices, wireless communication networks, geographic information and software applications that provide location-related guidance for customers," Kim said. "It differs from mobile position determination systems such as Global Positioning Systems (GPS) in that Location Based Services provide much broader, application-oriented location services."
While cars or hand-held electronic devices equipped with GPS may be useful when trying to get from one place to another, LBS go beyond providing routes and directions, functioning much the same way as a hotel concierge.
"For instance," Kim said, "if it's my wife's birthday, and on my way home from the office I need to pick up a birthday cake and a dozen roses, I would want to know not only where is the nearest bakery and floral shop, but where is the cheapest - or the right - place to find these things that I want."
The technology can be adapted for a wide range of other functions, he said, ranging from relaying locations of people requiring emergency assistance to first responders to providing alerts about traffic congestion.
Kim said the "proactive" decision by the research and standards communities and consumer-products manufacturers to come together and establish an industry standard for LBS before the market is flooded with devices offering concierge services is somewhat unusual, but highly practical.
"It's about trying to save a tremendous amount of money," he said.
"Usually when something is coming into the market - take for instance the Beta/VHS video formats - there's a lot of duplication and waste for consumers." In this case, "there's a huge market coming in, so there was agreement that we'd better get started ahead of time.
"My goal is to provide efficient service at the least cost."
To date, Kim said, 29 nations have endorsed the new ISO standard for adoption.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
