Constructing Perceptual Common Ground Between Human and Robot Through Joint Attention
Lee, Kangwoo,Choo, Hyunseung World Scientific Publishing Company 2017 INTERNATIONAL JOURNAL OF HUMANOID ROBOTICS Vol.14 No.3
<P>Joint attention is a communicative activity that allows social partners to share perceptual experiences by jointly attending to an environmental object. Unlike the common approach towards joint attention, which is based on the developmental view in robotics, here it is conceptualized with a psychophysical paradigm known as cueing. The triadic interaction of joint attention is formalized as the conditional probability of an attentional response for a given target candidate derived from object features and a cue derived from a human partner's indication. A robotic system to which the joint attention model is applied conducted a series of tasks to demonstrate the properties of the computational model. The robotic system successfully performed the tasks, which could not be specified by the information derived from a target object alone; furthermore, the system demonstrated how perceptual and selection ambiguity is resolved through joint attentive interaction and made to converge into a common perceptual state. The results imply that a perceptual common ground is constructed on the triadic relationship between user, robot, and objects through joint attentive interaction.</P>
Constructing Impressions with Multimedia Ringtones and a Smartphone Usage Tracker
( Kangwoo Lee ),( Hyunseung Choo ) 한국인터넷정보학회 2015 KSII Transactions on Internet and Information Syst Vol.9 No.5
In this paper, we studied facial impression construction with smartphones in a series of experiments with two smartphone applications: SmartRing and SystemSens+. In the first experiment, impressions of faces associated with different music genres (trot vs. classical) were compared to impressions formed from a facial image alone along the social warmth and intelligence dimensions. In the second experiment, the effect of similarity attraction was investigated by manipulating the extroversion of facial images. Results indicated that impressions of faces cannot only be constructed along the social warmth and intelligence dimensions, but can also be made more or less attractive based on their similarity to the viewer`s personality. Our experiments provide interesting insights into facial impressions formed in a smartphone environment.
Sharing Pattern Analysis of an OLTP Application
Lee, Kangwoo,Kim, Hiecheol Korea Society of Industrial Information Systems 2002 한국산업정보학회논문지 Vol.7 No.5
최근 다중 프로세서 시스템들이 상용 데이터베이스의 트랙잭션 처리에 널리 사용되고 있지만 데이터베이스의 데이터 공유 패턴에 대한 탐구는 거의 이루어지고 있지 않다. 본 논문에서는 캐쉬 일관성을 갖는 공유 메모리 구조의 다중 컴퓨터 상에서 대표적인 OLTP 응용 프로그램임 TPC-B 벤치마크에 대한 데이터 공유 패턴을 분석하였다. 또한 데이터 공유 패턴이 갖는 성능에 대한 영향을 분석하기 위하여 프로세서 개수, 캐쉬 크기, 그리고 캐쉬 블록 크기를 변화시켜 성능을 측정하였다. 이러한 성능 측정 결과로서 TPB-B는 과학기술 분야의 응용프로그램과는 확연히 다른 데이터 공유 특성을 갖고 있음을 확인하였다. Although multiprocessor systems are widely used in recent years to run commercial workloads, data sharing patterns are rarely explored due to several difficulties. In this paper, we made in-depth sharing pattern analysis for a representative OLTP application, the TPC-B benchmark, running on a cache-coherent shared-memory multiprocessor system. In addition, to illustrate their effects on the performance, the number of cache misses were measured for various numbers of processors, cache sizes and cache block sizes. From these measurements, we found out the shared data in TPC-B largely bear quite different sharing characteristics from those in scientific applications.
Standard protocol conversion of digital ECG for healthcare
Yonghee Lee,Sinhyuk Kang,Kangwoo Lee 한국정보기술학회 2017 Proceedings of The International Workshop on Futur Vol.2017 No.5
In this paper, we present a method for converting the digital SCPECG used in clinical practice to the MFER standard for use in health care. Since the SCP-ECG has a complex representation format for each section, we simplify the structure by separating only the items necessary for healthcare use. We convert the structure of each section of SCP-ECG to TLV format, such as tag, length, and value. The converted result is expressed in MFER format using different tags according to the expression contents. The results show that we can simplify the structure of the SCP-ECG and translate it into other standard formats, so that it can be used in the health care field.
