Obtaining a realistic imitation is essential in terms of perceived quality in human-robot interaction, but it is still a challenge due to the lack of effective mapping between human movements and the degrees of freedom of robotics systems. If high-level programming interfaces, software and simulation tools simplified robot programming, there is still a strong gap between robot control and natural user interfaces. In this paper, a system to reproduce on a robot the head movements of a user in the field of view of a consumer camera is presented. The system recognizes the presence of a user and its head pose in real-time by using a deep neural network, in order to extract head position angles and to command the robot head movements consequently, obtaining a realistic imitation. At the same time, the system represents a natural user interface to control the Aldebaran NAO and Pepper humanoid robots with the head movements, with applications in human-robot interaction.","PeriodicalId":420290,"journal":{"name":"International Conference on Artificial Intelligence and Virtual Reality","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127339131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The isolated personnel in hostile territory is of great value to both sides. For the sake of extremely high cost and massive consumption of time in military exercises, virtual reality is a preferred way to conduct the experiment. Mixed reality, known as MR, allows users to interact with the virtual objects, as well as the real objects. With MR devices, commanders get a better awareness of both virtual combat and real environment. Agent-based modelling is a relatively new approach to modelling systems composed of interacting objects. By analyzing the decision-making process of agents, codes are written to drive the simulation. Finally, the whole system is applied to HoloLens to provide a holographic demonstration.","PeriodicalId":420290,"journal":{"name":"International Conference on Artificial Intelligence and Virtual Reality","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115222118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the complex coordination of aircrafts in the fleet has caused great difficulties for the evaluation of mission effectiveness. This paper studies the method to evaluate the mission effectiveness of manned/ unmanned aerial team based on agent-based simulation and proposes an approach called resource consumption analyze to establish evaluation index system. This approach decomposes missions into multiple tasks, and further decomposes the process of tasks based on Observe-Orient-Decide-Act (OODA) to facilitate modeling tasks and developing evaluation indicators. Moreover, this paper builds the behavior models of combat units based on OODA and conducts several simulation experiments to evaluate the mission effectiveness of manned/unmanned aerial team. These experiments show that the evaluation approach based on OODA and agent-based simulation can help to evaluate the mission effectiveness of manned/unmanned aerial team and design more suitable aircraft for future warfare.","PeriodicalId":420290,"journal":{"name":"International Conference on Artificial Intelligence and Virtual Reality","volume":"435 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132453709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this method, the original image is first divided into several blocks for processing, and then the information of each pixel is converted to frequency coefficients, and a certain high frequency component is discarded, thus the image is lossy compressed. In this paper, the effect of block sizes on the quality of decompressed image is studied, so as to find out the optimal block sizes. Firstly, we make a theoretical analysis, and then verify my analysis results through experiment. In the experiment, the block sizes range from 1x1 to 512x512.

Sparse representation is an advanced data analysis algorithm based on compressive sensing. Traditionally, the sparse representation is performed on the global dictionary formed by all the training classes. Afterwards, the classification is made based on the reconstruction errors. This method did not consider the individual representation capabilities of different classes. So, a modified sparse representation is designed in this study by conducting the sparse representation on the local dictionary formed by each training class. Then, the reconstruction error of each class is computed and compared to determine the label of the test sample. In the experiments, the AR and Yale-B face image databases are employed to investigate the performance of the proposed method. The results show its effectiveness and robustness.","PeriodicalId":420290,"journal":{"name":"International Conference on Artificial Intelligence and Virtual Reality","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130012449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among all, in the recent years emerged the possibility to consider as soft biometrics also the temporal evolution of both the human attention and the emotional states, and some recent works in the literature partially explored this exciting research line making use of either expensive tools or RGB-D devices. This work is instead the first attempt to perform soft biometrics identification of individuals on the basis of data acquired by a consumer camera, looking at users' attention evolution in time. The experimental evidence of the feasibility of using the proposed framework as soft-biometrics is given on a set of 22 users recorded by a tablet front-facing camera while watching, in an unconstrained mobile setting, a video running on the tablet screen.","PeriodicalId":420290,"journal":{"name":"International Conference on Artificial Intelligence and Virtual Reality","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130953876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is achieved by devising specialized 2D visualization plots that capture gaze progression and gaze sustenance over time. In doing so, a low-resolution analysis is assumed, as is the case with most crowd surveillance videos wherein the retinal analysis and iris pattern extraction of individual subjects is made impossible. The information is useful for studies involving the random gaze behavior pattern of humans in a crowded place, or in a controlled environment in seminars or office meetings. The extraction of useful information regarding the attention span of the individual from the spatial and temporal analysis of gaze points is the subject of study in this paper. Different solutions ranging from plotting temporal gaze plots to sustained attention span graphs are investigated, and the results are compared with the existing techniques of attention span modeling and visualization.","PeriodicalId":420290,"journal":{"name":"International Conference on Artificial Intelligence and Virtual Reality","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117021657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
