In this paper, emotional motion representation is proposed for Human Robot Interaction: HRI. The proposed representation is based on <i>"Laban Movement Analysis: LMA"</i> and trajectories of 3-dimensional whole body joint positions using an RGB-D camera such as a <i>"Microsoft Kinect"</i>. The experimental results show that the proposed method distinguishes(More)
Nowadays, many robots have evolved to imitate human social skills such that sociable interaction with humans is possible. Socially interactive robots require abilities different from that of conventional robots. For instance, human-robot interactions are accompanied by emotion similar to human-human interactions, Robot emotional expression is thus very(More)
This paper suggests a system to detect multiple planes fast and roughly based on a depth map from depth camera ‘Kinect’. In order to improve the speed of the plane detection process, we compute local normal vectors of points of the depth map and we classify 3D point cloud data whether it includes in the same plane using these local normal vectors. It is(More)
This paper suggests an interactive facial robot system on a smart device which has a touch screen and a built-in microphone. The recognition process for touch inputs is enhanced by analyzing input patterns and a built-in microphone. Recognized results from the input procedure are converted to emotional states of the system, and then the emotional states are(More)
Human-robot interaction (HRI) is becoming more complex and difficult due to the growing number of capabilities demonstrated by socially interactive robots. From this perspective, it is necessary for us to have simple and general methods that enable robots to interact with human beings at an emotional level. Therefore, this paper suggests a method that can(More)
Quasi-periodic WO(3) nanoislands are introduced to extract two optical modes in organic light-emitting diodes. The nano-scaled and size-tunable WO(3) islands were fabricated by use of wet-etching with self-aggregated Ag mask. The improvement of light extraction efficiency originates to the recovery of light losses which are surface plasmon mode and(More)
Automobile shredder residue (ASR) from end-of-life vehicles (ELVs) in Korea has commonly been disposed of in landfills. Due to the growing number of scrapped cars and the decreasing availability of landfill space, effective technology for reducing ASR is needed. However ASR is a complex mixture, and finding an appropriate treatment is not easy on account of(More)
This study focuses on smart phones' suitability as a mean for online trading, and on the impact of smart phone services on customers' satisfaction. Key resources for smart phone trading services are classified in three categories: service contents, wireless network services and features of smart phones. For each category, critical-service-related factors(More)
As robots step into the human's daily lives, interaction and communication between human and robot is becoming essential. For this social interaction with humans, we propose an emotion generation model considering simplicity, believability and uncertainty. First, OCC model is simplified and then stochastic approach on emotion decision algorithm for(More)
