Crowdsourcing based global indoor localization sys..

School of Computing Intelligent Service Lab (Prof. Dong-Soo Han) announced that they have developed a system for providing global indoor localization using Wi-Fi signals. The technology uses numerous smartphones to collect fingerprints of location data and label them automatically, greatly reducing the cost of constructing an indoor localization system while maintaining high accuracy. The method can be used in any building in the world, provided the floor plan is available, and there are Wi-Fi fingerprints to collect. To accurately collect and label the location information of collected fingerprints, the research team analyzed indoor space utilization. This led to a technology that classified indoor space in to places used for stationary tasks (resting spaces), and spaces used to reach said places (transient spaces), and separate algorithms to optimally and automatically collect location labelling data. A few years ago, the team has also implemented a means of automatically labelling resting space locations from collected signals in various contexts such as homes, shops, and offices via the users’ address information. The latest one allows for the automatic labelling of transient spaces’ locations such as hallways, lobbies, and stairs using unsupervised learning, also without any additional location information. Testing in KAIST’s N5 building and the 7th floor of N1 building proved the technology is capable of 3 to 4 meter accuracy given enough training data. The accuracy is comparable to technology using manually labeled location information. Google, MS, and other multinational corporations collected tens of thousands of floor plans for their indoor localization projects. Indoor signal map collection was also attempted but proved more difficult. As a result, existing indoor localization services were often plagued by inaccuracies. In Korea, COEX, Lotte World Tower, and other landmarks provide comparatively accurate indoor localization, but most buildings suffer from the lack of signal maps, preventing indoor localization services. Professor Dong-Soo Han claims that “This technology allows easy deployment of highly accurate indoor localization system in any building in the world. In the near future, most indoor spaces will provide localization services, just like outdoor spaces.” He further added that although smartphone collected fingerprints were left unutilized and discarded to date, the development of an application for the data will create a new field of wireless LAN big data fingerprinting. This new indoor navigation technology is likely to be valuable to Google, Apple, or other global firms providing indoor localization information for the whole world. Nonetheless the technology will also be valuable for Korean localization service firms for domestic localization services. Prof. Han added that “the new global indoor localization system deployment technology will be added to KAILOS, KAIST’s indoor localization system.” KAILOS was released in 2014 as KAIST’s open platform for indoor localization service, allowing anyone in the world to add floor plans to KAILOS, and add the building’s signal fingerprint data to help create a universal indoor localization service. As localization accuracy improves in indoor environs, despite the absence of GPS signals, applications such as location based SNS, location based IoT, and location based O2O are expected to take off, leading to various improvements in convenience and safety. Integrated indoor-outdoor navigation service is also visible on the horizon, fusing vehicular navigation technology with indoor navigation.

Controlling a turtle with your mind…amazing techno..

Our very own School of Computing Professor Sungho Jo made an appearance on 8 O’clock News. Here is a copy of the segment. “Controlling a turtle with your mind…amazing technology” From SBS News (article in Korean) http://news.sbs.co.kr/news/endPage.do?news_id=N1003835422&plink=NEW&cooper=SBSNEWSSECTION&plink=COPYPASTE&cooper=SBSNEWSEND <Anchor> Control a turtle with but a thought. Just think “left” and it goes left, “right” and it goes right. This amazing technology is advancing every day. Reporter Kuhee Jung is with a story on how this is possible. <Reporter> Drink with a robot arm just by thinking about it. This is possible via the application of Brain-Computer Interface technology, where a computer reads the changes in brain waves that occurs when you think. Using this technology, you can control animals with just your thought. Turtles walk in figure 8 shaped paths, or walk in circles around an object: all done by a researcher thinking about it. The researcher can control the turtle with the use of a thought controlled curtain mounted on the turtle’s shell, taking advantage of turtles’ instinctive fear of darness, which forces them to walk towards the light. <Sungho Jo, Professor at KAIST> Turtles shrink when they can’t see, and head towards whichever direction their vision is not obscured. If we let them see to their right when the person thinks “right”, the turtle will instinctively walk to the right. <Reporter> These are brain waves, detected from various points on my head. The waveforms change according to whether I’m thinking “left” or “right”, which the computer analyzes, and once it understands what I’m thinking, it can read my mind. As Brain-Computer Interface technology advances, we expect to see applications such as robots to act as limbs of the disabled, remote controlled animals and robots for exploration, or real time analysis of emotions to help prevent mental illnesses such as depression.

Prof. Sung-Ju Lee Wins the WiNTECH Test of Time Aw..

On the 3rd of October, our very own School of Computing Professor Sung-Ju Lee won the 10th WiNTECH (ACM International Workshop on Wireless Network Testbeds, Experimental evaluation & CHaracterization) Test of Time Award in the workshop held in New York City, USA. WiNTECH, a wireless networking workshop started in 2007, has gained recognition for its focus on spotlighting practical research results via experimentation and verification. To celebrate the 10th anniversary of the workshop, the workshop’s first Test of Time Award was given. Test of Time Awards are given to papers that are still important in academia and industry many years since its original publication. Prof. Sung-Ju Lee’s paper “An Experimental Study on the Capture Effect in 802.11a Networks” received the Test of Time Award in a unanimous vote by the judges. The 2007 paper was a collaboration between Prof. Sung-Ju Lee and a Seoul National University research team. The research team showed via experiment that, despite the then common knowledge that signals affected by interference become unusable, the signals can be received depending on variables such as transmission power, transmission time, and transmission rate. The paper affected later wireless experiments and modeling research, and has been referenced more than 200 times. Prof. Lee commented that the award means a lot since it shows the paper is still impactful despite being almost 10 years since its original publication.
