The dynamics of human-machine interactions can vary from simple to complex. It spans a range that go from basic rule-based serial stimulus-response exchanges to more realistic bi-directional interactions that evolve in real-time according to (possibly) complex laws. Increasingly, a subset of such systems, those between humans and humanoid robots has been drawing more scrutiny because of their potential...
This paper presents a path planning strategy for a mobile robot. The path planning strategy is according to the experience that the mobile robot has been experienced in target navigation. The mixed reality technique is implemented by both the virtools tool and mobile robot. There are three basic interactive behaviors of human beings which have been implemented on this proposed mobile robot. They are...

The mixed reality technique is implemented by both the Virtools tool and mobile robot. There are three basic interactive behaviors of human beings have been implemented on this proposed mobile robot. There are target navigation behavior, face tracking behavior, and obstacles...
As an important product characteristic, maintainability is recognized as a highly significant factor in the economic success of engineering systems and products. With the rapid development of Virtual Reality (VR) technology, an intuitive, immersive and interactive environment for product maintenance is created in this paper. In order to analyze and evaluate the product maintainability in virtual maintenance...
In force reflecting teleoperator systems, the existence of even small communication delays and jitters may lead to transparency deterioration and instability. An alternative approach to the delayed force feedback is to design a virtual environment (VE) on the master side that duplicates the essential features of the remote slave-environment interconnection. In this work, we present an approach to...
A recent study has shown that computer graphic techniques may be used to extend human perceptual abilities in comprehending four-dimensional space. The current case study explored conditions such learning can occur. An experienced human observer watched computer generated graphical simulations of randomly shaped hyper-tetrahedrons and made judgments about the Euclidean distance between two of the...
At present, the lack of emotion is very serious in E-Learning. A solution is proposed in this paper. The importance of emotional education is discussed; the feasibility of emotional education is indicated based on virtual reality in E-Learning, including theories and advantages; the method of emotional teaching design is put forward; the emotional education system is designed and implemented in the...
An ??agent?? in a computer simulation is an object with a dynamic model driving its actions. There are different classifications for agents, for example: autonomous, intelligent, and software. A cell within a cellular automaton might be considered an agent with the complete environment being a multi-agent system. An object containing an artificial intelligence could also be considered an agent. Our...
The basis of all path finding is simple. It is the discovery of a number of vectors, which in combination, resulting in a path from one point to another. At the simplest level, in one dimension, it is finding the distance to the goal. Add a second dimension, followed by a third and the complexity increases exponentially, with direction becoming significant. This paper focused on the study of pathfinding...
Crowd systems are widely being exploited in a number of virtual environment applications such as games, virtual world and entertainment. These kinds of applications can provide the immersive feeling into the static scenes and therefore enhancing the reality of the systems. The problems involved in crowd modelling when we only focus on the crowds. For instance, the collision avoidance among a large...
User experience evaluation in human-robot interaction is most often an expensive and difficult task. To allow the evaluation of various factors and aspects of user experience, a fully functional (humanoid) robot is recommended. This work presents technical and methodological considerations on the applicability of the Wizard of Oz (WOz) approach to enable user experience evaluation in the field of...
This paper presents a novel method to implement an interactive mobile robot. The proposed mobile robot is implemented under the technique of mixed reality. The mixed reality technique is realized by both the Virtools tool and mobile robot. There are three basic interactive behaviors of human beings have been implemented on this proposed mobile robot. There are target navigation behavior, face tracking...
Recent advances in man-machine interaction, telerobotics, telepresence and teleaction have shown that introducing the haptic modality to multimedia applications has the power to significantly widen their application range and to dramatically improve the user experience. Especially, the human body surface has been considered as an additional means of presenting information using vibrotactile display...
We present a human motion model and animation for micro-sensor motion capture system. It consists of a sensor data-driven layered human motion model and an animation method using polygon group to achieve skin deformation. This method is based on biomechanics. The joints of human body were categorized according to the motion characteristics. Motion parameters estimated from sensor data are used to...
Crumbs and places, is a platform that aims to build a virtual image of the world based on geo-localized human activity. Relationships between people occur in places that are determinant in the kind of links that are established between people of the same community.
This paper presents a novel approach of 3D human posture recovering from monocular vision frame under the condition of which at least one depth value of a joint point is known in each monocular vision frame. This approach simplifies the calibration of CCD camera, and realizes the recovery of 3D human posture from monocular vision. Moreover, the methodology based on monocular vision can extensively...
This paper discusses a complementary tactile sensing and human interface for the robotic telemanipulation of physical objects in interactive haptic virtual environments.
When haptically interacting with virtual rigid bodies, the rendering and display of realistic haptic force-feedback is a challenging task. Conventionally rendered closed-loop proportional feedback forces according to Hooke's law or potential fields impart a feeling of soft contacts and hence are not sufficient to convey the material contact properties of a rigid object. Improvement of haptic contact...
This paper discussed such possibility that viewed sense to aesthetic feeling experiences of virtual space as subjects in aesthetics, through describing some aesthetic phenomena and experiences in the present virtual field, then to put forward to some imagines on developing the visual field of nowaday aesthetics. And it expected to make a research by comparing between traditional time-space and digital...
The application of motivation psychology on crowd simulation is an interesting topic. Agents in a crowd should have motivations and behaviours, and make decisions in a certain virtual environment by themselves. A formalization of motivation is presented by fuzzy mathematical methods and a computational motivation model for agents is set up. An agent's local motion within a group is based on Helbing's...
