Human-Robot Interaction
Robot-based Imitation Intervention for Children with Autism Spectrum Disorders (ASD), 2012 - 2013
	Overview Autism Spectrum Disorders (ASD) is a developmental disorder which causes the lack of social interaction and communication skills. The recent research revealed that one out of 34 children in Korea was diagnosed with ASD. In spite of this high prevalence rate, there are not enough institutions which provide care and interventions for autistic children. Therefore, this research investigates the development and the use of an interactive robot for autistic children. Additional information Hwang, J., Kim, M. G., & Cho, K. (2013).

Human-Robot Interaction
Recognizing User's Personality Traits based on Tactile Interaction Patterns with a Robot, 2011 - 2012
	Overview Personality analysis has been an important topic in psychology and human-robot interaction (HRI) as well. Main theme of this research is to explore the relationship between individual’s personality traits and tactile interaction patterns with a robot. A sociable robot Pleo was used in the experiment. The tactile interaction patterns of the participants with the robot were video-recorded and analyzed. The result showed that individual’s personality traits could be inferred based on the tactile interaction patterns with a robot. Additional information Hwang, J., & Lee, K. C. (2015).

Haptics
Multimodal Teaching of English Intonation for Non-native Students, 2011 - 2012
	Overview Speaking is one of the most important skills in second language learning (L2). Speaking is more difficult than reading or listening because of the difficulties in acquiring the intonation patterns of the second language. To address these difficulties, two different vibrotactile devices were designed and implemented to teach English intonation because the learning of intonation is a part of muscle and motor training. The devices were designed to present English intonation using vibrotactile feedback in order to increase L2 learners’ awareness of English intonation. Additional information Hwang, J., & Cho, K.

Haptics
Vibrotactile In-vehicle Navigation Aid, 2011 - 2012
	Overview I designed and implemented an in-vehicle haptic navigation system to overcome the limitations of current navigation systems. The haptic interface using vibrotactile signals with a 5-by-5 tactor array was installed on the back of the chair. Despite of cognitive load levels, valid cue conditions elicited shorter response times than invalid cue and no cueing conditions. The result strongly supports the uses of vibrotactile cues in in-vehicle navigation systems. Additional information Hwang, J., Chung, K., Hyun, J., Ryu, J., & Cho, K. (2012).
