HY-Live, the World’s First Telepresence Lecture at Hanyang University

Telepresence lectures for educational innovation

What is telepresence technology? “Tele”  implies long distance, and “presence” means existence. Combined, telepresence is communicating with someone far away, who seems just as real as if they were right in front of our eyes. The idea of telepresence was to  effectively deliver a soccer lesson in real time to an elementary student in Korea from Son Heung-min, a Korean soccer player in England, through a mobile communication company. Hanyang University applied this telepresence technology to the learning site of university education for the first time among any domestic universities.
HY-Live telepresence system model

HY-Live is a 5G telepresence based hologram that combines offline and online classes, a new lecture method that Hanyang University pioneered. How is HY-Live distinct from online lectures? Firstly, while online lectures emphasized the slogan, “Anytime, anywhere,” telepresence lectures are “live," and therefore, enable more active and direct communication between the instructor and the learners. Enhanced creativity and intellectual curiosity that follow the active bidirectional communication are not the only benefits of adopting telepresence technology in university education. For the many physical difficulties that ensue in the traditional classroom teaching method, including the limitation of the number of students allowed per classroom and the narrow accessibility of popular instructors, telepresence technology seems to shine through without the constraints given by space or distance.
Lee Tae-hee, the general manager of the Education Innovation Team, shared the path of educational innovation at Hanyang University through telepresence lectures.

Rewinding to where the motives for developing telepresence lectures began, a visit to the Monterrey Institute of Technology and Higher Education in Mexico gave the broad idea of utilizing telepresence technology using holography to give lessons in class. Now, Hanyang University is the first university to adopt 5G technology at telepresence lectures.

Hanyang University successfully operated the HY-Live lectures based on 5G telepresence, and conducted the course Chemistry for Everyday Life, with Professor Kim Min-kyung (Department of Chemistry) in the spring semester of 2019. A total of 103 students took the course, a number that is far greater than the original limit. Kim proceeded with the lecture at a studio at Hanyang University and her hologram was broadcasted live in three separate classrooms, with around 30 students in each. The professor asked students questions while staring into the camera and was able to scan the classes through the screen next to the camera. Students enthusiastically participated in the class, answering quizzes through an app, and asking the professor questions.

Telepresence is a matter of how real it seems. Hanyang University developed the large size hologram screen by incorporating smart glass.  The large screen was also useful when instructors used the smart pad in their hands to show class materials or videos.
While the usage of telepresence technology in education is just beginning to sprout, it is a goal of Hanyang University to conduct a concurrent lecture at ERICA campus starting next year, building a consortium with local and foreign universities in which Hanyang leads, and to provide education in line with the Fourth Industrial Revolution. “Our fundamental goal is to achieve a virtuous cycle of education innovation, profit creation, and reinvestment into education innovation. Students are the largest beneficiaries in this model,” said Lee Tae-hee, the general manager of the Education Innovation Team.
