This paper introduces a model which connects representations of the space surrounding a virtual humanoid’s body with the space it shares with several interaction partners. This work intends to support virtual humans (or humanoid robots) in near space interaction and is inspired by studies from cognitive neurosciences on the one hand and social interaction studies on the other hand. We present o...

Virtual Enterprises (VEs) are an appropriated cooperation alternative and a way of gaining competitive advantage for enterprises. In this context, a promising form to extend the formation process of VEs is performing new product search and development. This proposal is being developed in a Brazilian project called VIRTEC Virtual Organization of Technology. In order to develop Virtual Products, ...

We consider fundamental capacity limits in wireless networks where nodes can cooperate in transmission and reception. Cooperation can take many forms, including virtual multiple-input multiple-output transmission, different relaying strategies, and conferencing. The optimal cooperation strategy depends on the network topology, the channel SNR, and the channel side information available at the n...

The virtual enterprise is usually cited as an innovative inter-organizational configuration. Is it possible to justify and to assert the innovativeness of virtual enterprises just by claiming that they are made up of innovative “elements”? Is a sum of innovative features making the resulting system innovative too? This contribution will investigate the conditions and the situations in which a v...

Virtual organizations play an important role in today’s economy, as they are able to adapt themselves to the turbulent market environments. Team work and collaboration are main characteristics of virtual organizations, so the contacts among human beings have outstanding importance. A very important element of this human contact is trust. Trust building in virtual organizations has special chara...

In this paper, we analyze the performance of an agent developed according to a well-accepted appraisal theory human emotion with respect how it modulates play in context social dilemma. We ask if will be capable generating interactions that are considered more than machine-like. conducted experiment 117 participants and show rated our on dimensions human-uniqueness (separating humans from anima...

We introduce a system to interact with computers using real objects as interface. The graspable model on the table has a congruent counterpart in the computer which is updated continuously. The use of concrete objects offers advantages for interaction and cooperation. The underlying virtual model provides capabilities like remote visualization, simulation and documentation which play an importa...

In this paper the problem of variable admittance control in human-robot cooperation tasks is investigated, considering rotational motion of the robot’s end-effector. A Fuzzy Model Reference Learning algorithm is used to determine online the appropriate virtual damping of the admittance controller with partial state representation of the system. The learning algorithm is trained according to the...
