The main challenge of this paper is study whether people's empathic reactions towards robots change depending on previous information given to human about the robot before the interaction. The use of false data about robot skills creates different levels of what we call ‘fake empathy'. This study performs an experiment in WOZ environment in which different subjects (n=17) interacting with the same robot while they believe that the robot is a different robot, up to three versions. Each robot scenario provides a different ‘humanoid' description, and out hypothesis is that the more human-like looks the robot, the more empathically can be the human responses. Results were obtained from questionnaires and multi- angle video recordings. Positive results reinforce the strength of our hypothesis, although we recommend a new and bigger and then more robust experiment.

Our system captures users' experiences by wearable sensors (camera, microphone, infrared ID tracker) as well as ubiquitous esnsors (same as above); and to capture events from multiple viewpoints simultaneously.

It can (1) make plausible assumptions,(2) reason with multiple alternatives,(3) switch the search process to the maximally plausible alternative,(4) detect contradiction and tame conclutions which depend on inconsistent assumptions, and (5) update plausibility factor of each belief based on new observations.

Building Empathic Agents? Comment on “Computational Modelling of Culture and Affect” by Aylett and Paiva
Abstract This comment discusses work by Aylett and Paiva (2012) which describes a synthetic appro... more Abstract This comment discusses work by Aylett and Paiva (2012) which describes a synthetic approach to building a virtual world inhabited by synthetic characters where the user can experience subjective culture, that is, the experience of social reality, and learn how to empathetically communicate with people in other cultures. It provides a computational theory for integrating recent findings on emotion and cultural sensitivities into an interactive drama played by interacting characters with varying personalities.

Ultrafiltration in Food Processing Industry: Review on Application, Membrane Fouling, and Fouling Control
Abstract Ultrafiltration process has been applied widely in food processing industry for the last... more Abstract Ultrafiltration process has been applied widely in food processing industry for the last 20 years due to its advantages over conventional separation processes such as gentle product treatment, high selectivity, and lower energy consumption. Ultrafiltration becomes an essential part in food technology as a tool for separation and concentration. However, membrane fouling compromises the benefits of ultrafiltration as fouling significantly reduces the performance and hence increases the cost of ultrafiltration.
Neary: conversation field detection based on similarity of auditory situation

Neary operates on a simple algorithm and a light-weight process, so other systems can incorporate it smoothly. In this paper, we show an implementation of our Neary system and its experimental evaluations.

A big challenge is to develop a technology for augmenting the conversational environment so that people can conduct even better conversational interactions for collective intelligence and creation.

In order to develop a mutually adaptive interactive robot system, we take a bootstrapping approach consisting of three stages: a human-human WOZ experiment, a human-robot WOZ experiment, and a human-adaptive robot experiment.

POC provides a worthy test bed to explore an ideal style of knowledge-creating community. The research of POC contributes to the development of agent technologies that enhances interaction in a community. At the beginning of this paper, we introduce a complete system image of POC.

Conversational knowledge process for social intelligence design

The next step is to realize knowledgeable communities on the ubiquitous network. Social Intelligence Design is a field of research on harmonizing people and artifacts by focusing on social intelligence, defined as the ability of actors and agents to learn and to solve problems as a function of social structure and to manage their relationships with each other.

In this paper, I present Communicative Intelligence as a step towards solving the understanding and communication bottleneck by inventing communicative artifacts that enable people and artifacts to interact with each other in a natural fashion.
Location-based Photo Sharing Game that Facilitates Experience Sharing

Players of the proposed game compete for ownership of areas associated to the real-world by submitting photos taken by themselves. To maintain their area ownership, they have to keep adding comments on the photos so valuable that satisfy other players.(author abst.)
Presentation agents by reusing past conversational data in exhibition sites

This paper proposes a prototyping system of poster exhibition guidance by playing back recorded speech. The system consists of a component extracting conversations and the other representing them. The method of extraction is to extract a conversation as a cluster of utterances, which is annotated with information of" what was it about".

Technical information have been accumulated in an electronic form as documents which contain texts, pictures and movies in enterprises. However, it needs expert knowledge to make use of these technical information. In this paper, we describe an ontology-centric framework, called intelligent corporate base (ICoB) which organizes a technical information into documents, assists a comprehension of documents and helps share information.
