K-Glass 3 Offers Users a Keyboard to Type Text
KAIST researchers upgraded their smart glasses with a low-power multicore processor to employ stereo vision and deep-learning algorithms, making the user interface and experience more intuitive and convenient. K-Glass, smart glasses reinforced with augmented reality (AR) that were first developed by KAIST in 2014, with the second version released in 2015, is back with an even stronger model. The latest version, which KAIST researchers are calling K-Glass 3, allows users to text a message or type in key words for Internet surfing by offering a virtual keyboard for text and even one for a piano. Currently, most wearable head-mounted displays (HMDs) suffer from a lack of rich user interfaces, short battery lives, and heavy weight. Some HMDs, such as Google Glass, use a touch panel and voice commands as an interface, but they are considered merely an extension of smartphones and are not optimized for wearable smart glasses. Recently, gaze recognition was proposed for HMDs including K-Glass 2, but gaze cannot be realized as a natural user interface (UI) and experience (UX) due to its limited interactivity and lengthy gaze-calibration time, which can be up to several minutes. As a solution, Professor Hoi-Jun Yoo and his team from the Electrical Engineering Department recently developed K-Glass 3 with a low-power natural UI and UX processor. This processor is composed of a pre-processing core to implement stereo vision, seven deep-learning cores to accelerate real-time scene recognition within 33 milliseconds, and one rendering engine for the display. The stereo-vision camera, located on the front of K-Glass 3, works in a manner similar to three dimension (3D) sensing in human vision. The camera’s two lenses, displayed horizontally from one another just like depth perception produced by left and right eyes, take pictures of the same objects or scenes and combine these two different images to extract spatial depth information, which is necessary to reconstruct 3D environments. The camera’s vision algorithm has an energy efficiency of 20 milliwatts on average, allowing it to operate in the Glass more than 24 hours without interruption. The research team adopted deep-learning-multi core technology dedicated for mobile devices. This technology has greatly improved the Glass’s recognition accuracy with images and speech, while shortening the time needed to process and analyze data. In addition, the Glass’s multi-core processor is advanced enough to become idle when it detects no motion from users. Instead, it executes complex deep-learning algorithms with a minimal power to achieve high performance. Professor Yoo said, “We have succeeded in fabricating a low-power multi-core processer that consumes only 126 milliwatts of power with a high efficiency rate. It is essential to develop a smaller, lighter, and low-power processor if we want to incorporate the widespread use of smart glasses and wearable devices into everyday life. K-Glass 3’s more intuitive UI and convenient UX permit users to enjoy enhanced AR experiences such as a keyboard or a better, more responsive mouse.” Along with the research team, UX Factory, a Korean UI and UX developer, participated in the K-Glass 3 project. These research results entitled “A 126.1mW Real-Time Natural UI/UX Processor with Embedded Deep-Learning Core for Low-Power Smart Glasses” (lead author: Seong-Wook Park, a doctoral student in the Electrical Engineering Department, KAIST) were presented at the 2016 IEEE (Institute of Electrical and Electronics Engineers) International Solid-State Circuits Conference (ISSCC) that took place January 31-February 4, 2016 in San Francisco, California.

Professor Hoi-Jun Yoo Appointed as the First Asian University Chairman of the ISSCC
Hoi-Jun Yoo, a professor of Electrical Engineering Department at KAIST, was chosen to be the first Asian University Chairman of the ISSCC (International Solid-State Circuits Conference) held in San Francisco, USA, from February 10 to 13, 2014. His term will last one year from April, 2014. Professor Yoo ranked tenth globally in thesis achievement over the 60-year history of the ISSCC. He ranked fourth globally over the last ten years and was the highest-ranked member from Asia over that time. He received an award for this remarkable achievement in 2012. ISSC is a world-renowned conference in the semiconductor field, where only 200 strictly selected papers are presented by semiconductor-related enterprises, research centers, and university representatives. Nicknamed the “The Olympics of the Semiconductor”, ISSCC runs for 4 days and hosts more than 3000 semiconductor engineers from around the world. It is most famous for the first CPU presentation by Intel and the first memory technology release of Samsung. Professor Yoo stated, “The Korean Semiconductor Engineering is leading the world’s technology instead of imitating it.” He aspires to devote himself to upgrading semiconductor engineering around the world.
A Light Weight, Energy Effcient Household Polysomnography (PSG) System Developed
A smart ‘household polysomnography (PSG) system’ was developed by domestic research team. Professor Yoo Hui Joon and his research team of KAIST’s department of Electricity and Electronic Engineering successfully developed a PSG system that is light weight and has high performance levels. The conventional PSG systems were complex with numerous lines and wires. The PSG is used to monitor biological signals during sleep and the monitored results are used to diagnose and cure sleep-related illnesses and disorders. However because of restrictions like the size of the machine, impurities, and the change in environment, multiple trials over several days were required to obtain accurate data. The system developed by the research team is lighter than a q-tip so as to not disturb the patient’s sleep. It also has Intelligent Circuit (IC) that detects when sensors come detached and automatically replaces the sensor with another sensor thereby allowing continual monitoring of the user. A low-power consuming circuit was implemented allowing the entire system to run continuously on a single coin battery for 10 hours which effectively decreased the weight of the system and simultaneously allows for uninterrupted monitoring of the user over the entire sleep cycle. Even a remote diagnosis system can be implemented. The user will don the PSG and sleep at home, ensuring that a normal heat beat rate, brain waves, breathing, etc. will be monitored. The data procured overnight can be sent to the experts online who will be able to diagnose remotely. The research team plans on performing research in cooperation with the KAIST hospital and U-Healthcare research. The research result is winning worldwide rave. The system was announced in the International Solid-State Circuits Conference (ISSCC) and was published in ISSCC magazine and in Japan’s NIKKEI Electronics January edition.
Texas Instruments, Inc. Agreed for Collaborative Research with Professor Hai-Joon Yoo, the Electrical Engineering Department of KAIST
Professor Hai-Joon Yoo from the Electrical Engineering Department of KAIST made a research collaboration agreement with Texas Instruments (TI), Inc. in July 2010 to develop a “Many-core Processor Chip,” a chip that is designed to emulate a human brain. TI, Inc. is an American company based in Dallas, Texas and renowned for developing and commercializing semiconductor and computer technology. The company is the 4th largest manufacturer of semiconductors worldwide, 2nd supplier of chips for cellular handsets, and 1st producer of digital signal processors and analog semiconductors, among a wide range of semiconductor products. TI, Inc. has designated Professor Yoo’s lab as one of its official labs and promised to give financial supports for the lab—it has pledged to donate a total value of 300 million won of research fund and equipment to Professor Yoo. On July 21, 2010, the signboard hanging ceremony for the designation of a TI Lab was held at Professor Yoo’s lab. Professor Yoo developed a neuro-circuit network to emulate a human brain by adopting a mixed mode circuit that has chips for analog and digital circuits. He then has conducted a research to graft the mixed mode circuit onto a Many-core Processor to integrate the human intelligence into a conventional single-core processor that can process one instruction at a time. The Many-core Processor, once developed, can be applied to various kinds of products such as an artificial intelligence surveillance camera, robot, smart car, and the like. Professor Yoo has presented his research results at numerous international meetings and conferences, among other things, the International Solid-State Circuits Conference (ISSCC), a global forum sponsored by the Institute of Electrical and Electronics Engineers (IEEE) for presentation of advances in solid-state circuits and Systems-on-a-Chip. The Conference offers a unique opportunity for engineers working at the cutting edge of IC design to maintain technical currency, and to network with leading experts. Professor Yoo is a senior member of IEEE and Chairman of ISSCC in Asia.
A Breakthrough for Cardiac Monitoring: Portable Smart Patch Makes It Possible for Real-time Observation of Heart Movement
Newly invented device makes the monitoring easier and convenient. Professor Hoi-Jun Yoo of KAIST, Department of Electrical Engineering, said that his research team has invented a smart patch for cardiac monitoring, the first of its kind in the world. Adhesive and can be applied directly to chest in human body, the patch is embedded with a built-in high performance semiconductor integrated circuit (IC), called Healthcare IC, and with twenty five electrodes formed on the patch’s surface. The 25-electrodes, with a capability of creating various configurations, can detect cardiac contractions and relaxations and collect electrocardiogram (ECG) signals. The Healthcare IC monitors ECG signals and sends the information to a portable data terminal like mobile phones, making it possible for a convenient, easy check up on cardiac observations. The key technologies used for the patch are the Healthcare IC that measures cardiovascular impedance and ECG signals, and the electronic circuit board made of four layers of fabric, between which electrodes, wireless antenna, circuit board, and flexible battery are installed. With the P-FCB (Planar Fashionable Circuit Board) technology, the research team explained, electrodes and a circuit board are directly stacked into the fabric. Additionally, the Healthcare IC (size: 5mm x 5mm), which has components of electrode control unit, ECG and cardiovascular resistance detection unit, data compression unit, Static Random Access Memory (SRAM), and wireless transmitter receiver, is attached on the fabric. The Healthcare IC is operated by an ultra-low electrical power. Like a medicated patch commonly used to relieve arthritis pains, the surface of smart patch is adhesive so that people can carry it around without much hassle. A finished product will be 15cm x 15 cm in size and 1mm high in thickness. The Healthcare IC can measure cardiovascular impedance variances with less than 0.81% distortion in 16 different configurations through differential current injectors and reconfigurable high sensitivity detection circuitry. “The patch will be ideal for patients who suffer a chronic heart disease and need to receive a continuous care for their condition. Once commercialized, the patch will allow the patients to conduct a self-diagnosis at anytime and anywhere,” said Yan Long, a member of the research team. There has been a continuously growing demand worldwide since 2000 for the development of technology that provides a suitable healthcare management to patients with a chronic heart disease (e.g., cardiovascular problems), but most of the technology developed today are only limited to monitoring electrical signals of heart activity. Cardiovascular monitors, commonly used at many of healthcare places nowadays, are too bulky to use and give uncomfortable feelings to patients when applied. Besides, the current monitors are connected to an electrical line for power supply, and they are unable to have a low power communication with an outdoor communication gadget, thus unavailable for wide use. Professor Yoo gave his presentation on this new invention at an international conference, International Solid-State Circuits Conference, held on February 8-10 in San Francisco. The subject of his presentation was “A 3.9mW 25-electorde Reconfigurable Thoracic Impedance/ECG SoC with Body-Channel Transponder.” (Picture 1) Structure of Smart Patch (Picture 2) Smart patch when applied onto human body (Picture 3) Data received from smart patch (Picture 4) Healthcare IC
