The four-region model with 7 specified subregions represents a theoretical construct of functionally segregated divisions of the cingulate cortex based on integrated neurobiological assessments. Under this framework, we aimed to investigate the functional specialization of the human cingulate cortex by analyzing the resting-state functional connectivity(More)
Finding empty parking spaces is a common problem in densely populated areas. Drivers spend an unnecessarily large amount of time searching for the empty spots, because they do not have perfect knowledge about the available vacant spots. An effective vacancy detection system would significantly reduce search time and increase the efficiency of utilizing the(More)
With the introduction of new depth sensing technologies, interactive hand-gesture devices are rapidly emerging. However, the hand-gestures used in these devices do not follow a common vocabulary, making certain control command device-specific. In this paper we present an initial effort to create a standardized interactive hand-gesture vocabulary for the(More)
This paper proposes a method to assess the overall fatigue of human body movement. First of all, according to previous research regarding localized muscular fatigue, a linear relation is assumed between the mean frequency and the muscular working time when the muscle is experiencing fatigue. This assumption is verified with a rigorous statistical analysis.(More)
Three-dimensional (3D) sensing and printing technologies have reshaped our world in recent years. In this article, a comprehensive overview of techniques related to the pipeline from 3D sensing to printing is provided. We compare the latest 3D sensors and 3D printers and introduce several sensing, postprocessing, and printing techniques available from both(More)
With an ever-increasing accessibility to different multimedia contents in real-time, it is difficult for users to identify the proper resources from such a vast number of choices. By utilizing the user’s context while consuming diverse multimedia contents, we can identify different personal preferences and settings. However, there is a need to reinforce the(More)
For machines to converse with humans, they must at times resolve ambiguities. We are developing a conversational robot which is able to gather information about its world through sensory actions such as touch and active shifts of visual attention. The robot is also able to gain new information linguistically by asking its human partner questions. Each kind(More)
