 Welcome to ISI Laboratory!!

With the wide spread of smart phones equipped with GPS, WiFi, and Bluetooth sensors, Location Based Service (LBS) has become one of critical services for smart phone vendors, service providers, and users to date. Real time localization using GPS, WiFi, Bluetooth sensors and signals is an essential pre-step for location based services. Zigbee, RFID, or UWB can be commonly used for localization as well if they are attached to or integrated with smart phones. Among them, due to cost and coverage, we have been extensively studying and developing techniques for WiFi-based Real Time Locating System (RTLS) for the last several years.

As a result, we have developed a WiFi based indoor localization system leveraging user participation so called collective intelligence, and announced it to Android application market in the name of Elekspot (http://www.elekspot.com). It has localization services and moreover it enables one to develop various indoor location based applications using the APIs provided by Elekspot.

We also developed a WiFi-based indoor navigation system. The system is bundled together with myCoex (http://www.coex.co.kr) and released to general users very recently. It is known as the first commercial WiFi-based indoor navigation system applied to such a large scale in real field. The system covers the entire vast 9th-floor COEX area, in which approximately 700,000 people visit the place every day.
 
Current and Future Researches

Based on the techniques, systems, and platforms for indoor localization developed at ISI Lab., we will continue to develop new techniques and services for WiFi based RTLS. Reliable and robust WiFi based indoor localization techniques and tools, seemless integration of indoor and outdoor navigation systems, location based Social Networking Service (SNS), location based e-Coupon service are within the scope of our current and future researches.
 
Brief History

Before ISI Lab. was get involved into RTLS several years ago, we had endeavored to develop IT-based convergence technologies in various areas such as bioinformatics, e-Healthcare, workflow management systems. We started researches on bioinformatics in around 2000 and we developed a unique protein-protein interaction prediction system in 2005. The system, named PreSPI (http://code.google.com/p/prespi/), is the first system adopted the notion of domain combination in the computational model for the prediction of protein-protein interactions.

THE-MUSS is an e-Health service platform developed in ISI Lab. through the collaborative work with Samsung during 2005-2008. The system has become a pioneering system incorporating smart phones in e-Healthcare services and it has been delivered to Samsung for further development. THE-MUSS is implemented on a workflow management system, WebVine, which has been developed in ISI Lab. since 1998.

Research Reselts and Activities

We have published numereous papers, registered dozens of patents, and released several products through journals, conferences, and mass media. The following is the list of news web sites and video clips introducing our research activities and results. Most of them are related to WiFi based indoor localization.   

  • WiFi based indoor localization(YTN, mk, chosen, donga, etnews, ...)
  • WiFi based COEX indoor navigation system (KBS, hk)
  • Elekspot: WiFi based Indoor localizaton system(Elekspot)
  • Location based working place monitoring(ftp)
  • Location based business card exchange(ftp)
  • Location based discount card recommendation(ftp)
  • papers and patents(publication)
