GPS finds new crowd-control and medical applications By JUDY SIEGEL-ITZKOVICH

A Hebrew University researcher has shown that GPS can control crowds or the movement of shoppers, and even evaluatE patient recovery after surgery. Global positioning systems (GPS) have become commonplace to help drivers reach their destinations using satellites. But a young Hebrew University of Jerusalem researcher has shown that GPS can have other uses as well, such as controlling crowds or the movement of shoppers, and even evaluating patient recovery after surgery.
Michal Isaacson, a doctoral student working with Dr. Noam Shoval of HU’s geography department, has been involved in developing new approaches for the use of advanced tracking technologies. Her work has implications for understanding the activity of people in different settings, such as urban areas, shopping malls, theme parks, national parks and other tourist attractions. It has already been tested to evaluate crowd activity and flow at Spain’s Port Aventura theme park.
For her research, Isaacson has been named the first-prize winner among students in this year’s competition for HU’s Kaye Innovation Awards at the Hebrew University. The prizes will be presented on June 9 at the university’s Board of Governors meeting. Her work in this field has resulted in a book coauthored with Dr. Shoval and in several articles published in leading geographic journals. The first article she coauthored, published in The Professional Geographer, was noted by the journal as one of the top five most-cited articles in 2006 to 2007.
The system she and Shoval have developed uses GPS technology to record the location of people for a designated period of time. During this period, participants are required to carry a small GPS unit with them. The tracking data is then analyzed using a computerized, time/space analysis engine, to derive maps that indicate the volumes of activity throughout the location and charts that indicate how different types of populations spent their time in the location.
The data obtained using tracking technologies can also be analyzed in real time, creating virtual “radar” of the activity of visitors throughout a destination. Real-time analysis can lead to dynamic management of attractions in a more efficient way, both expanding the number of people that can visit an attraction within a given time frame and controlling their flow to promote sales. The analysis of this data can also change the way attractions are planned, and enable effective planning of future additions to an attraction.
The technology also has far-reaching medical applications, they say. In collaboration with Dr. Yair Barzilay of the HU-Hadassah Medical School and Hadassah University Medical Center’s orthopedic surgery unit, a method was developed for detecting the mobility of patientsafter surgery as an objective measure for their recovery and well-being. The patients carry a GPS unit with them after the operation, tracking their movements, which are then analyzed. Future development will integrate additional sensors that will allow the combination of GPS data with physiological data, such as heart rate and blood pressure.
The system was recently licensed through Yissum, HU’s technology transfer company, to Location Based Intelligence Inc., a US company, for further development and commercialization in the medical arena. Defining the potential market for this invention in the field of medical application is difficult at this stage, mainly because this product is creating a new market.
