Hwan Kim
Assistant Professor 
Department of Service and Design Engineering
Sungshin Women’s University

Hello. I am a design researcher with an interest in virtual/augmented reality + haptic interactions. I’ve been designing various I/O interfaces — such as wearable haptic devices, VR/AR controllers, physical user interfaces — that are involved in human haptic perception, and exploring the novel possibilities of the haptic interactions. My research focuses on developing novel I/O interfaces that provide rich haptic information to users who want natual interaction with VR/AR.

Before joining Sungshin Women’s University, I was a senior UX designer at Samsung Electronics, and designed&#38;nbsp;One UI of Samsung Galaxy Watch series (Galaxy Watch Active 2, Galaxy Watch 3, and Galaxy Watch 4). I completed my Ph.D. in Department of Industrial Design at KAIST in 2019, advised by Prof. Woohun Lee (Wonder Lab).&#38;nbsp;

Abstract
Haptic devices allow a more immersive experience with Virtual and Augmented Reality. However, for a wider range of usage they need to be miniaturized while maintaining the quality of haptic feedback. In this study, we used two kinds of human sensory illusion of vibration. The first illusion involves creating a virtual force (pulling sensation) using asymmetric vibration, and the second involves imparting compliances of complex stress-strain curves (i.e. force-displacement curves of mechanical keyboards) to a rigid object by changing the frequency and amplitude of vibration. Using these two illusions, we developed a wearable tactile device named HapCube, consisting of three orthogonal voicecoil actuators. Four measurement tests and four user tests confirmed that 1) a combination of two orthogonal asymmetric vibrations could provide a 2D virtual force in any tangential directions on a finger pad, and 2) a single voicecoil actuator produced pseudo-force feedback of the complex compliance curves in the normal direction.

Interactive Seesaw is an installation work that visitors to the science museum can experience. It was developed in collaboration with National Science Museum in South Korea (located in Daejeon).&#38;nbsp;This project was one of three works, which were finally completed a year later. I led this project for two out of three years, and participated as a supporter in the last year.&#38;nbsp;You can see the final result HERE.

Abstract
A virtual touch screen concept using an optical see-through head-mounted display has been suggested. With a virtual touch screen, the user's direct-touch interactions are allowed in much the same way as a conventional touch screen, but the absence of haptic feedback and physical constraint leads to poor user performance. To overcome this issue, we developed a wearable haptic device, called HapThimble. It provides various types of haptic feedback (tactile, pseudo-force, and vibrotactile) to the user's fingertip and mimics physical buttons based on force-penetration depth curves. We conducted three experiments with HapThimble. The first experiment confirmed that HapThimble could increase a users' performance when conducting clicking and dragging tasks. The second experiment revealed that users could differentiate between six types of haptic feedback, rendered based on different force-penetration depth curves obtained using HapThimble. Last, we conducted a test to investigate the similarity between the physical buttons and the mimicked haptic buttons and obtained a 90.3% success rate.

Abstract
Since smart phones adopted touchscreen, users have been enjoying large displays. However, when using soft keyboard, the available size of the display becomes less than 50%. In this paper Back Keyboard, a physical keyboard installed backside of mobile phone, is presented. Also the design process with a prototype through a series of studies is described. User evaluation was conducted with the prototype; the average text entry rate was 15.3 WPM (SD: 3.6) and the error rate was 12.2% (SD: 9.0) after a 40-minute typing session. Moreover, the text entry rates of Back Keyboard and general keyboards for PCs did not have significant relations. This means that the prototype could be used smoothly regardless of one’s ability of typing on a PC.
