Augmented Reality Application for Smart Tour
‘K-Culture Time Machine,’ an augmented and virtual reality application will create a new way to take a tour. Prof. Woon-taek Woo's research team of Graduate School of Culture Technology of KAIST developed AR/VR application for smart tourism.
The 'K-Culture Time Machine' application (iOS App Store app name: KCTM) was launched on iOS App Store in Korea on May 22 as a pilot service that is targetting the Changdeokgung Palace of Seoul.
The application provides remote experience over time and space for cultural heritage or relics thorough wearable 360-degree video. Users can remotely experience cultural heritage sites with 360-degree video provided by installing a smartphone in a smartphone HMD device, and can search information on historical figures, places, and events related to cultural heritage. Also, 3D reconstruction of lost cultural heritage can be experienced.
Without using wearable HMD devices, mobile-based cultural heritage guides can be provided based on the vision-based recognition on the cultural heritages. Through the embedded camera in smartphone, the application can identify the heritages and provide related information and contents of the hertages. For example, in Changdeokgung Palace, a user can move inside the Changdeokgung Palace from Donhwa-Gate (the main gate of the Changdeokgung Palace), Injeong-Jeon(main hall), Injeong-Moon (Main gate of Injeong-Jeon), and to Huijeongdang (rest place for the king). Through the 360 degree panoramic image or video, the user can experience the virtual scene of heritages.
The virtual 3D reconstruction of the seungjeongwon (Royal Secretariat) which does not exist at present can be shown of the east side of the Injeong-Jeon The functions can be experienced on a smartphone without a wearable device, and it would be a commercial application that can be utilized in the field once the augmented reality function which is under development is completed.
Professor Woo and his research team constructed and applied standardized metadata of cultural heritage database and AR/VR contents. Through this standardized metadata, unlike existing applications which are temporarily consumed after development, reusable and interoperable contents can be made.Professor Woo said, "By enhancing the interoperability and reusability of AR contents, we will be able to preoccupy new markets in the field of smart tourism."
The research was conducted through the joint work with Post Media (CEO Hong Seung-mo) in the CT R&D project of the Ministry of Culture, Sports and Tourism of Korea. The results of the research will be announced through the HCI International 2017 conference in Canada this July.

Improving Traffic Safety with a Crowdsourced Traffic Violation Reporting App
KAIST researchers revealed that crowdsourced traffic violation reporting with smartphone-based continuous video capturing can dramatically change the current practice of policing activities on the road and will significantly improve traffic safety.
Professor Uichin Lee of the Department of Industrial and Systems Engineering and the Graduate School of Knowledge Service Engineering at KAIST and his research team designed and evaluated Mobile Roadwatch, a mobile app that helps citizen record traffic violation with their smartphones and report the recorded videos to the police.
This app supports continuous video recording just like onboard vehicle dashboard cameras. Mobile Roadwatch allows drivers to safely capture traffic violations by simply touching a smartphone screen while driving. The captured videos are automatically tagged with contextual information such as location and time. This information will be used as important evidence for the police to ticket the violators. All of the captured videos can be conveniently reviewed, allowing users to decide which events to report to the police.
The team conducted a two-week field study to understand how drivers use Mobile Roadwatch. They found that the drivers tended to capture all traffic risks regardless of the level of their involvement and the seriousness of the traffic risks. However, when it came to actual reporting, they tended to report only serious traffic violations, which could have led to car accidents, such as traffic signal violations and illegal U-turns. After receiving feedback about their reports from the police, drivers typically felt very good about their contributions to traffic safety.
At the same time, some drivers felt pleased to know that the offenders received tickets since they thought these offenders deserved to be ticketed. While participating in the Mobile Roadwatch campaign, drivers reported that they tried to drive as safely as possible and abide by traffic laws. This was because they wanted to be as fair as possible so that they could capture others’ violations without feeling guilty. They were also afraid that other drivers might capture their violations.
Professor Lee said, “Our study participants answered that Mobile Roadwatch served as a very useful tool for reporting traffic violations, and they were highly satisfied with its features. Beyond simple reporting, our tool can be extended to support online communities, which help people actively discuss various local safety issues and work with the police and local authorities to solve these safety issues.”
Korea and India were the early adaptors supporting video-based reporting of traffic violations to the police. In recent years, the number of reports has dramatically increased. For example, Korea’s ‘Looking for a Witness’ (released in April 2015) received more than half million reported violations as of November 2016. In the US, authorities started tapping into smartphone recordings by releasing video-based reporting apps such as ICE Blackbox and Mobile Justice. Professor Lee said that the existing services cannot be used while driving, because none of the existing services support continuous video recording and safe event capturing behind the wheel.
Professor Lee’s team has been incorporating advanced computer vision techniques into Mobile Roadwatch for automatically capturing traffic violations and safety risks, including potholes and obstacles. The researchers will present their results in May at the ACM CHI Conference on Human Factors in Computing Systems (CHI 2017) in Denver, CO, USA. Their research was supported by the KAIST-KUSTAR fund.

Mechanical Engineering Building on Campus Refurbished
KAIST’s Mechanical Engineering Department has finished the project to remodel its buildings and hosted an opening ceremony on December 12, 2016, which was attended by the university’s senior management and guests including President Steve Kang and Choong-Hwan Ahn, Architecture Policy Officer at the Ministry of Land, Infrastructure and Transport of Korea (MLIT).
With an investment of approximately USD 10 million, the old buildings (each consisting of seven floors and one basement) were transformed into smart, green buildings. Among the upgrades were the establishment of LED lighting systems, the replacement of the exterior walls with insulated materials, and the installation of double-glazed windows, all resulting in the improvement of the buildings’ energy efficiency. Previously, offices and lecture halls in the buildings had individual cooling and heating systems, which consumed a great deal of energy, but they were replaced with a centralized smart energy control system that monitors the operation status as well as energy consumption in real time.
With these new improvements, the Department was able to slash its energy consumption by 32%, for which it received Green Building Conversion Certification from MLIT. The ministry issues the certification to buildings that reduce their energy consumption by over 20% as a result of infrastructure upgrades. Beginning with the Mechanical Engineering buildings, KAIST will work on obtaining this certification for all of its buildings that are either under renovation or construction.
President Kang said, “We are pleased to offer our students a comfortable environment for study and research and will continue improving outdated facilities and infrastructure to make the campus safer and nicer.”

An App to Digitally Detox from Smartphone Addiction: Lock n' LOL
KAIST researchers have developed an application that helps people restrain themselves from using smartphones during meetings or social gatherings.
The app’s group limit mode enforces users to curtail their smartphone usage through peer-pressure while offering flexibility to use the phone in an emergency.
When a fake phone company released its line of products, NoPhones, a thin, rectangular-shaped plastic block that looked just like a smartphone but did not function, many doubted that the simulated smartphones would find any users. Surprisingly, close to 4,000 fake phones were sold to consumers who wanted to curb their phone usage.
As smartphones penetrate every facet of our daily lives, a growing number of people have expressed concern about distractions or even the addictions they suffer from overusing smartphones.
Professor Uichin Lee of the Department of Knowledge Service Engineering at the Korea Advanced Institute of Science and Technology (KAIST) and his research team have recently introduced a solution to this problem by developing an application, Lock n’ LoL (Lock Your Smartphone and Laugh Out Loud), to help people lock their smartphones altogether and keep them from using the phone while engaged in social activities such as meetings, conferences, and discussions.
Researchers note that the overuse of smartphones often results from users’ habitual checking of messages, emails, or other online contents such as status updates in social networking service (SNS). External stimuli, for example, notification alarms, add to smartphone distractions and interruptions in group interactions.
The Lock n’ LoL allows users to create a new room or join an existing room. The users then invite meeting participants or friends to the room and share its ID with them to enact the Group Limit (lock) mode. When phones are in the lock mode, all alarms and notifications are automatically muted, and users must ask permission to unlock their phones. However, in an emergency, users can access their phones for accumulative five minutes in a temporary unlimit mode.
In addition, the app’s Co-location Reminder detects and lists nearby users to encourage app users to limit their phone use. The Lock n’ LoL also displays important statistics to monitor users’ behavior such as the current week’s total limit time, the weekly average usage time, top friends ranked by time spent together, and top activities in which the users participated.
Professor Lee said,
“We conducted the Lock n’ LoL campaign throughout the campus for one month this year with 1,000 students participating. As a result, we discovered that students accumulated more than 10,000 free hours from using the app on their smartphones. The students said that they were able to focus more on their group activities. In an age of the Internet of Things, we expect that the adverse effects of mobile distractions and addictions will emerge as a social concern, and our Lock n’ LoL is a key effort to address this issue.”
He added, “This app will certainly help family members to interact more with each other during the holiday season.”
The Lock n’ LoL is available for free download on the App Store and Google Play: https://itunes.apple.com/lc/app/lock-n-lol/id1030287673?mt=8.

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.

'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.

KAIST Develops a Method to Transfer Graphene by Stamping
Professor Sung-Yool Choi’s research team from KAIST's Department of Electrical Engineering has developed a technique that can produce a single-layer graphene from a metal etching. Through this, transferring a graphene layer onto a circuit board can be done as easily as stamping a seal on paper.
The research findings were published in the January 14th issue of Small as the lead article.
This technology will allow different types of wafer transfer methods such as transfer onto a surface of a device or a curved surface, and large surface transfer onto a 4 inch wafer. It will be applied in the field of wearable smart gadgets through commercialization of graphene electronic devices.
The traditional method used to transfer graphene onto a circuit board is a wet transfer. However, it has some drawbacks as the graphene layer can be damaged or contaminated during the transfer process from residue from the metal etching. This may affect the electrical properties of the transferred graphene.
After a graphene growth substrate formed on a catalytic metal substrate is pretreated in an aqueous poly vinyl alcohol (PVA) solution, a PVA film forms on the pretreated substrate. The substrate and the graphene layers bond strongly. The graphene is lifted from the growth substrate by means of an elastomeric stamp.
The delaminated graphene layer is isolated state from the elastomeric stamp and thus can be freely transferred onto a circuit board. As the catalytic metal substrate can be reused and does not contain harmful chemical substances, such transfer method is very eco-friendly.
Professor Choi said, “As the new graphene transfer method has a wide range of applications and allows a large surface transfer, it will contribute to the commercialization of graphene electronic devices.” He added that “because this technique has a high degree of freedom in transfer process, it has a variety of usages for graphene and 2 dimensional nano-devices.”
This research was sponsored by the Ministry of Science, ICT and Future Planning, the Republic of Korea.
