Professor Woontack Woo Demonstrates an Optical Platform Technology for Augmented Reality at Smart Cloud Show
Professor Woontack Woo of the Graduate School of Culture Technology at KAIST participated in the Smart Cloud Show, a technology exhibition, hosted by the university’s Augmented Human Research Center and presented the latest development of his research, an optical platform system for augmented reality.
This event took place on September 16-17, 2015 at Grand Seoul Nine Tree Convention Center in Seoul.
At the event, Professor Woo introduced a smart glass with an embedded augmented reality system, which permits remote collaboration between an avatar and the user’s hand.
The previous remote collaboration was difficult for ordinary users to employ because of its two-dimensional screen and complicated virtual reality system.
However, with the new technology, the camera attached to artificial reality (AR) glasses recognizes the user’s hand and tracks it down to collaborate. The avatar in the virtual space and the user’s hand interact in real space and time.
The key to this technology is the stable, real-time hand-tracking technique that allows the detection of the hand’s locations and the recognition of finger movements even in situations of self-occlusion.
Through this method, a user can touch and manipulate augmented contents as if they were real-life objects, thereby collaborating remotely with another user who is physically distant by linking his or her movements with an avatar.
If this technology is adopted widely, it may bring some economic benefits such as increased productivity due to lower costs for mobility and reduction in social overhead costs from the decrease in the need of traveling long distance.
Professor Woo said, “This technology will provide us with a greater opportunity for collaboration, not necessarily restricted to physical travelling, which can be widely used in the fields of medicine, education, entertainment, and tourism.”
Professor Woo plans to present his research results on hand-movement tracking and detection at the 12th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI 2015), to be held on October 28-30, 2015, at Kintex in Goyang, Korea.
He will also present a research paper on remote collaboration at the ICAT-EGVE 2015 conference, the merger of the 25th International Conference on Artificial Reality and Telexistence (ICAT 2015) and the 20th Eurographics Symposium on Virtual Environments (EGVE 2015), which will take place on October 28-30, 2015 at the Kyoto International Community House, Kyoto, Japan.

A Technology Holding Company Establishes Two Companies Based on Technologies Developed at KAIST
Mirae Holdings is a technology holding company created by four science and technology universities, KAIST, DIGIST (Daegu Gyeongbuk Institute of Science and Technology), GIST (Gwangju Institute of Science and Technology), and UNIST (Ulsan National Institute of Science and Technology) in 2014 to commercialize the universities’ research achievements. The company identifies promising technologies for commercialization, makes business plans, establishes venture capitals, and invests in startup companies.
Over the past year, Mirae Holdings has established two venture companies based on the technologies developed at KAIST. In September 2014, it founded Cresem Inc., a company used the anisotropic conductive film (ACF) bonding technology, which was developed by Professor Kyung-Wook Paik of the Material Science and Engineering Department at KAIST. Cresem provides a technology to bond electronic parts ultrasonically. The company is expected to have 860,000 USD worth of sales within the first year of its launching.
Last June, Mirae Holdings created another company, Doctor Kitchen, with the technology developed by Professor Gwan-Su Yi of the Bio and Brain Engineering Department at KAIST. Doctor Kitchen supplies precooked food, which helps diabetic patients regulate their diet. The company offers a personalized diet plan to customers so that they can effectively manage their disease and monitor their blood sugar level efficiently.
The Chief Executive Officer of Mirae Holdings, Young-Ho Kim, said, “We can assist KAIST researchers who aspire to create a company based on their research outcomes through various stages of startup services such as making business plans, securing venture capitals, and networking with existing businesses.”

KAIST Startups Annually Engage 33,000 People, and Their Sales Total Nearly 10 Billion Dollars
According to a recent study, KAIST startups annually engage 33,000 people, and their sales total nearly 10 billion US dollars. Also amongst 1,245 companies, 50 were listed in stock markets including KOSDAQ and KONEX. President Kang of KAIST commissioned an evaluation of KAIST startups last year. The report consisted of six chapters: current status of entrepreneurs and companies, cross analysis based on individuals’ background and academic degree, annual performance analysis, and current status of startup assistance.
The report categorized the startups with respect to the founders’ background. Of 1,245 companies, KAIST alumni founded 929 (74.6%) of the companies under study: 191 (15.3%) were located within the KAIST campuses, 91 (7.3%) were founded by enrolled students, and 74 (2.7%) by professors. The startup founders had different levels of education: 515 (41.4%) founders had master’s degree, 443 (35.6%) Ph.D. degree, and only 213 (17.1%) had only bachelor’s degree as the highest level of education attained. The reason behind the majority of founders having a master’s degree or higher degree is that many people established a startup after obtaining specialized knowledge and skills.
Focusing on the founders’ college majors, 719 (70.6%) founders were from the engineering department, 111 (10.9%) from the business administration department, 103 (10.1%) from the natural science department, and 86 (8.4%) from other departments. Looking at the companies' locations, 462 (37.5%) were placed in Seoul, 355 (28.8%) in Daejeon, and 273 (22.2%) in Gyeonggi.
By the end of 2013, the total asset of 1,069 companies came to 12 billion and 444 million dollars. Their total sales figure was 10 billion and 13 million dollars, and annual employments summed up to 33,000 people. The companies generated a significant portion of gross regional domestic product (GRDP) in each region. They formed 0.49% of GRDP of Seoul, took up 1.67% GRDP of Gyeonggi, and 5.53% of that of Daejeon.
Along with the performance analysis, the report also took a survey of suggestions on future startup assistance and opinions on current startup assistance policies. To a question asking what constituted the most difficult part of startup, 31.7% of respondents answered “attraction of investment,” 22.8% chose “a lack of human resources,” and 16.8% said “consulting” amongst 214 respondents. The study showed that major and medium enterprises face difficulty in finding human resources whereas small businesses experience obstacles attracting investment. Some startups had help from KAIST: 44 startups were provided with the office space, 21 had educational supports, and 18 were supported in research and development.
The report demonstrates that startups established by KAIST alumni and members play a key role in the South Korean economy despite KAIST’s short startup history, which began only since the end of 1990s. Based on this report, KAIST plans to listen continuously to the needs of alumni founders, and use those responses as a guide to entrepreneurship education for current students.
The Dean of the Office of University and Industry Cooperation, Joongmyeon Bae, who oversaw the publication of this report, said, "As this report is the first in Korea to study the status of alumni startups, it will be incredibly valuable in modifying the startup assistance policies.”
To spread an entrepreneurial spirit and start-up cultures in the campus and enhance the startup supporting system, KAIST has founded various startup centers on and off the campus.

'Dr. M,' Mobile Healthcare Showroom Opened at KI
Portable and wearable computers have made the way we manage our health easier and potentially more effective. Researchers from six departments and one graduate school at KAIST collaborated and conducted a one-year project called the “Mobile Healthcare Innovation” to develop a mobile healthcare system. Their research results are on exhibit on campus at the “Dr. M Showroom” which was open on March 13, 2015.
Located on the second floor of the College of Information and Electrical Engineering building, the showroom displays the entirety of mobile healthcare system developed during 2014, from the collection of biological data through smart sensors to analyzing big data to provide customized healthcare models for patients.
Standing in for a mobile doctor, Dr. M is a networked medical service system provided through the Internet of Things (IoC), wearable electronics, smart home, and smart car. Under this care, people can monitor their health on a daily basis at any-time and place, helping them to lower the risk of serious health problems. Patients who have chronic diseases such as diabetes or cardiovascular illness can inform doctors of their health status in real time. Moreover, people living in remote regions can receive quality medical services without traveling long distances.
At the showroom, about 40 convergence technologies are displayed, including biological sensors, low-power communication devices, IoC technology, big data, disease analysis, and prediction technology, presenting how these technologies are connected and worked systematically. For example, all the data earned from biological sensors are analyzed to produce relevant user information. Once abnormalities are discovered, the results would be sent immediately to medical staff for treatment.
As part of Dr. M, KAIST has been implementing the establishment of a “Mobile Healthcare Campus,” distributing small, wearable wristbands to 100 students. The wristbands read students’ biological signals and send them to researchers for monitoring. In addition, KAIST plans to collaborate with local hospitals, nursing care centers, communications, and mobile healthcare service providers for the commercialization of Dr. M system.
Professor Hoi-Jun Yoo of the Electrical Engineering Department, who has led the Mobile Healthcare Innovation project said, “One of the great advantages Dr. M can offer is the capability to customize healthcare service based on individuals and ages. For individuals in their twenties, for example, healthcare services such as skincare and diet programs will be more relevant whereas blood pressure monitoring for patients in their fifties and early diagnosis for the recurrence of diseases for those in their seventies. If we define human history in terms of major technology advancements, the first big one was computation, communication for the second, and I think ubiquitous healthcare will be the third one. We will continue to develop Dr. M in collaboration with medical and research organizations.”
A total of 32 professors from the Departments of Electrical Engineering, Computer Science, Industrial and Systems Engineering, Industrial Design, Web Science, Knowledge Service Engineering, and the Information Security Graduate School participated in the Mobile Healthcare Innovation project.

How Science Understands the Beauty of Fine Arts from the Medieval Era to the 19th Century
A research team, consisting of Professor Hawoong Jeong of the Department of Physics at KAIST and Assistant Professor Seung-Woo Son of the Department of Applied Physics at Hanyang University, conducted a research project to understand visual representations through the eyes of science, i.e., quantitative analyses. Researchers took a sample of reproductions of European paintings from the 11th to the early 19th centuries and analyzed them based on three elements: the usage of color, the variety of painted colors, and the brightness of the images.
For the large-scale quantitative analysis, the research team utilized digital images of the paintings obtained from the Web Gallery of Art, a virtual museum and searchable database of European fine arts that includes over 29,000 pieces, ranging from the years 1000 to 1850. The Web Gallery classifies paintings into ten art historical periods such as Medieval, Renaissance, Mannerist, Baroque, Rococo, Romantic, and Realist.
For each period, researchers investigated the frequency of certain colors which appear in paintings and examined the variety of painted colors, paying particular attention to paintings created by two iconoclastic artists from different eras: Pieter Bruegel the Elder and Jackson Pollock. In their works, the researchers discovered that specific pigments were preferred in each period, the result of reflecting historical facts into fine arts. For example, certain rare colors were used in the medieval age for political and religious reasons, and artists in that era employed a technique to layer one color over another dry color in order to express mixed colors, resulting in thickly textured brushstrokes because they considered mixing colors impure. Moreover, oil colors and color mixing techniques were not fully developed until the Renaissance age.
According to the research team, fewer numbers of colors were used before the 20th century, and the introduction of new expressionist tools, like the use of pastels and fingers directly on canvas, and painting techniques, such as “chiaroscuro” and “sfumato,” made much more colorful and natural expressions possible after the Renaissance period. The team said that the color arrangement of Jackson Pollock’s drip paintings differed substantially from other paintings, showing randomness, especially in the spatial arrangement of colors.
Researchers also examined one of the artistic effects applied to paintings, contrast, an important element to express shape and space in two dimensional fine arts. Among various types of contrasts, they said, brightness contrast is the most important in art history due to the cultural background of Europe which usually adopts the contrast of light and darkness as a metaphorical expression. Taking the color information of pixels and their spatial arrangement, the researchers studied the prevalence of brightness contrast in European paintings over ten artistic periods by developing a correlation function to measure the contrast. These mathematical measurements quantitatively describe the birth of new painting techniques including chiaroscuro and sfumato and their increasing use. For instance, in the medieval age, the contour of objects or images in paintings was vague, but it became much clearer later in the Romantic period.
Professor Jeong said, “The complexity of the material world has been a long-lasting topic of interest in natural science, but research in the structural complexity of art and humanities has only begun since the development of the Internet, with the availability of big data in these fields. Our research is a meaningful attempt to understand the underling intricacy of art and humanities based on a scientific approach, expressed quantitatively.”
The research results were published online on December 11, 2014 in Scientific Reports, entitled “Large-Scale Quantitative Analysis of Painting Arts.” The paper was also selected as one of the weekly research highlights by Nature and is noted on its online journal’s website.
