Lee, Seunghwan, Han, Jaehyun and Lee, Geehyuk (2011): MultiPress: releasing keys for multitap segmentation. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 1489-1494.

While MultiTap is one of the most popular text entry methods for mobile phones, it has a fundamental weakness known as MultiTap segmentation problem. Based on the observation that the thumb does not leave the keys between tapping actions, we designed a MultiTap segmentation method where the release action of the thumb is used to indicate input completion. A user study using a touch-sensing keypad prototype to explore the feasibility of the idea and a comparison test to access its benefit revealed promising results supporting the effectiveness of the proposed segmentation method.

Heo, Seongkook, Han, Jaehyun, Choi, Sangwon, Lee, Seunghwan, Lee, Geehyuk, Lee, Hyong-Euk, Kim, SangHyun, Bang, Won-Chul, Kim, DoKyoon and Kim, Changyeong (2011): IrCube tracker: an optical 6-DOF tracker based on LED directivity. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 577-586.

Six-degrees-of-freedom (6-DOF) trackers, which were mainly for professional computer applications, are now in demand by everyday consumer applications. With the requirements of consumer electronics in mind, we designed an optical 6-DOF tracker where a few photo-sensors can track the position and orientation of an LED cluster. The operating principle of the tracker is basically source localization by solving an inverse problem. We implemented a prototype system for a TV viewing environment, verified the feasibility of the operating principle, and evaluated the basic performance of the prototype system in terms of accuracy and speed. We also examined its application possibility to different environments, such as a tabletop computer, a tablet computer, and a mobile spatial interaction environment.

Lee, Seunghwan, Seo, Jungsuk and Lee, Geehyuk (2010): An adaptive speed-call list algorithm and its evaluation with ESM. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 2019-2022.

We designed an algorithm to build a speed-call list adaptively based on mobile phone call logs. Call logs provide the time-dependent calling patterns of mobile phone users, and therefore a speed-call list based on them will be more successful in recommending a desired number than a speed-call list based on recent calls only. This paper presents the design process of our algorithm for an adaptive speed-call list, its verification result with recorded call logs, and in-situ evaluation results of the algorithm using an Experience Sampling Method (ESM) system.

Lee, Seunghwan, Lee, Geehyuk and Kim, Hojin (2008): Ubigraphy: a third-person viewpoint life log. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 3531-3536.

A traditional life-log is written in the first-person viewpoint since a user collects data using sensors worn on the body. A UbiGraphy that we introduce here is a third-person viewpoint life-log that is made possible by the spontaneous interaction between a wearable computer and smart objects in a ubiquitous computing environment. A wearable computer uses smart objects in the proximity to capture a user's smiles, poses, and even songs from the third-person viewpoint, and then write a life-log where a user appears. This paper presents the design of a protocol that enables UbiGraphy and our first prototyping effort for experiencing UbiGraphy.
