Japan has more robots than any other country with robots contributing to many areas of society, including manufacturing, healthcare,
and entertainment. However, few studies have examined Japanese attitudes toward robots, and none has used implicit measures.
This study compares attitudes among the faculty of a US and a Japanese university. Although the Japanese faculty reported
many more experiences with robots, implicit measures indicated both faculties had more pleasant associations with humans.
In addition, although the US faculty reported people were more threatening than robots, implicit measures indicated both faculties
associated weapons more strongly with robots than with humans. Despite the media’s hype about Japan’s robot ‘craze,’ response
similarities suggest factors other than attitude better explain robot adoption. These include differences in history and religion,
personal and human identity, economic structure, professional specialization, and government policy. Japanese robotics offers
a unique reference from which other nations may learn.

Negative attitudes toward robots are considered as one of the psychological factors preventing humans from interacting with
robots in the daily life. To verify their influence on humans‘ behaviors toward robots, we designed and executed experiments
where subjects interacted with Robovie, which is being developed as a platform for research on the possibility of communication
robots. This paper reports and discusses the results of these experiments on correlation between subjects’ negative attitudes
and their behaviors toward robots. Moreover, it discusses influences of gender and experience of real robots on their negative
attitudes and behaviors toward robots.

There are only a few ethical regulations that deal explicitly with robots, in contrast to a vast number of regulations, which
may be applied. We will focus on ethical issues with regard to “responsibility and autonomous robots”, “machines as a replacement
for humans”, and “tele-presence”. Furthermore we will examine examples from special fields of application (medicine and healthcare,
armed forces, and entertainment). We do not claim to present a complete list of ethical issue nor of regulations in the field
of robotics, but we will demonstrate that there are legal challenges with regard to these issues.

The complexity of group dynamics occurring in small group interactions often hinders the performance of teams. The availability
of rich multimodal information about what is going on during the meeting makes it possible to explore the possibility of providing
support to dysfunctional teams from facilitation to training sessions addressing both the individuals and the group as a whole.
A necessary step in this direction is that of capturing and understanding group dynamics. In this paper, we discuss a particular
scenario, in which meeting participants receive multimedia feedback on their relational behaviour, as a first step towards
increasing self-awareness. We describe the background and the motivation for a coding scheme for annotating meeting recordings
partially inspired by the Bales’ Interaction Process Analysis. This coding scheme was aimed at identifying suitable observable
behavioural sequences. The study is complemented with an experimental investigation on the acceptability of such a service.

The paper reflects on the unique experience of social and technological development in Lithuania since the regaining of independence
as a newly reshaped society constructing a distinctive competitive IST-based model at global level. This has presented Lithuanian
pattern of how to integrate different experiences and relations between generations in implementing complex information society
approaches. The resulting programme in general is linked to the Lisbon objectives of the European Union. The experience of
transitional countries in Europe, each different but facing some common problems, may be useful to developing countries in
Africa.

Batch reinforcement learning methods provide a powerful framework for learning efficiently and effectively in autonomous robots.
The paper reviews some recent work of the authors aiming at the successful application of reinforcement learning in a challenging
and complex domain. It discusses several variants of the general batch learning framework, particularly tailored to the use
of multilayer perceptrons to approximate value functions over continuous state spaces. The batch learning framework is successfully
used to learn crucial skills in our soccer-playing robots participating in the RoboCup competitions. This is demonstrated
on three different case studies.

The European Union co-funded COMUNICAR (communication multimedia unit inside car) project designed and developed an integrated multimedia human–machine interface (HMI) able to manage a wide variety of driver information systems (from entertainment to safety). COMUNICAR proposed an innovative information provision paradigm, in which the on-vehicle HMI is able to tailor the delivery of the information in real time according to the actual driving context and the drivers workload. COMUNICAR adopted a user-centred design process involving an iterative development based on extensive user tests since the early phases of the project. This approach was particularly useful to define and improve the layout of the user interface and specify the rules that decide the scheduling and the modalities of the delivery of the information messages to the driver. This paper introduces the COMUNICAR concept and the user-centred flow of design. Then, a concrete case of user-test driven, iterative improvement of a systems functionality is presented. We also briefly describe two software tools that we have designed to enhance the development process in a user-centred perspective. Finally, the future evolution of the concept of smart and safe information scheduling is sketched and discussed. 相似文献

This paper describes the simulated car racing competition that was arranged as part of the 2007 IEEE Congress on Evolutionary
Computation. Both the game that was used as the domain for the competition, the controllers submitted as entries to the competition
and its results are presented. With this paper, we hope to provide some insight into the efficacy of various computational
intelligence methods on a well-defined game task, as well as an example of one way of running a competition. In the process,
we provide a set of reference results for those who wish to use the simplerace game to benchmark their own algorithms. The paper is co-authored by the organizers and participants of the competition.

We have built a mobile robotic platform that features an Active Robotic Head (ARH) with two high-resolution cameras that can
be switched during robot operation between two configurations that produce respectively panoramic and stereoscopic images.
Image disparity is used for improving the quality of the texture. The robot head switches dynamically, based on robot operation
between the stereoscopic configuration and the panoramic configuration.

Quantitative usability requirements are a critical but challenging, and hence an often neglected aspect of a usability engineering process. A case study is described where quantitative usability requirements played a key role in the development of a new user interface of a mobile phone. Within the practical constraints of the project, existing methods for determining usability requirements and evaluating the extent to which these are met, could not be applied as such, therefore tailored methods had to be developed. These methods and their applications are discussed. 相似文献

We present a study of using camera-phones and visual-tags to access mobile services. Firstly, a user-experience study is described in which participants were both observed learning to interact with a prototype mobile service and interviewed
about their experiences. Secondly, a pointing-device task is presented in which quantitative data was gathered regarding the speed and accuracy with which participants aimed and clicked
on visual-tags using camera-phones. We found that participants’ attitudes to visual-tag-based applications were broadly positive,
although they had several important reservations about camera-phone technology more generally. Data from our pointing-device
task demonstrated that novice users were able to aim and click on visual-tags quickly (well under 3 s per pointing-device
trial on average) and accurately (almost all meeting our defined speed/accuracy tradeoff of 6% error-rate). Based on our findings,
design lessons for camera-phone and visual-tag applications are presented.

Listening to music on personal, digital devices whilst mobile is an enjoyable, everyday activity. We explore a scheme for
exploiting this practice to immerse listeners in navigation cues. Our prototype, ONTRACK, continuously adapts audio, modifying
the spatial balance and volume to lead listeners to their target destination. First we report on an initial lab-based evaluation
that demonstrated the approach’s efficacy: users were able to complete tasks within a reasonable time and their subjective
feedback was positive. Encouraged by these results we constructed a handheld prototype. Here, we discuss this implementation
and the results of field-trials. These indicate that even with a low-fidelity realisation of the concept, users can quite
effectively navigate complicated routes.

This article presents the results of video-based Human Robot Interaction (HRI) trials which investigated people’s perceptions
of different robot appearances and associated attention-seeking features and behaviors displayed by robots with different
appearance and behaviors. The HRI trials studied the participants’ preferences for various features of robot appearance and
behavior, as well as their personality attributions towards the robots compared to their own personalities. Overall, participants
tended to prefer robots with more human-like appearance and attributes. However, systematic individual differences in the
dynamic appearance ratings are not consistent with a universal effect. Introverts and participants with lower emotional stability
tended to prefer the mechanical looking appearance to a greater degree than other participants. It is also shown that it is
possible to rate individual elements of a particular robot’s behavior and then assess the contribution, or otherwise, of that
element to the overall perception of the robot by people. Relating participants’ dynamic appearance ratings of individual
robots to independent static appearance ratings provided evidence that could be taken to support a portion of the left hand
side of Mori’s theoretically proposed ‘uncanny valley’ diagram. Suggestions for future work are outlined.

Autonomous robots that are capable of learning are being developed to make it easier for human actors to achieve their goals.
As such, robots are primarily a means to an end and replace human actions (or parts of them). An interdisciplinary technology
assessment was carried out to determine the extent to which a replacement of this kind makes ethical sense in terms of technology,
economics and legal aspects. Proceeding from an ethical perspective, derived from Kant’s formula of humanity, in this article
we analyse the use of robots in the care of the elderly or infirm and then examine robot learning in the context of this kind
of cooperation.

Research on hybrid bionic systems (HBSs) is still in its infancy but promising results have already been achieved in laboratories.
Experiments on humans and animals show that artificial devices can be controlled by neural signals. These results suggest
that HBS technologies can be employed to restore sensorimotor functionalities in disabled and elderly people. At the same
time, HBS research raises ethical concerns related to possible exogenous and endogenous limitations to human autonomy and
freedom. The analysis of these concerns requires reflecting on the availability of scientific models accounting for key aspects
of sensorimotor coordination and plastic adaptation mechanisms in the brain.

In this paper, we propose a manipulation system for agricultural robots that handle heavy materials. The structural systems
of a mobile platform and a manipulator are selected and designed after proposing new knowledge about agricultural robots.
Also, the control systems for these structural systems are designed in the presence of parametric perturbation and uncertainty
while avoiding conservative results. The validity of both the structural and control systems is confirmed by conducting watermelon
harvesting experiments in an open field. Furthermore, an explicit design procedure is confirmed for both the structural and
control systems and three key design tools are clarified.

Awareness systems have attracted significant research interest for their potential to support interpersonal relationships.
Investigations of awareness systems for the domestic environment have suggested that such systems can help individuals stay
in touch with dear friends or family and provide affective benefits to their users. Our research provides empirical evidence
to refine and substantiate such suggestions. We report our experience with designing and evaluating the ASTRA awareness system,
for connecting households and mobile family members. We introduce the concept of connectedness and its measurement through
the Affective Benefits and Costs of communication questionnaire (ABC-Q). We inform results that testify the benefits of sharing
experiences at the moment they happen without interrupting potential receivers. Finally, we document the role that lightweight,
picture-based communication can play in the range of communication media available.

The purposes of this study are (a) to establish a measurement for evaluating conversational impressions of group discussions,
and (b) to make an exploratory investigation on their interactional processes which may affect to form those impressions.
The impression rating and factor analysis undertaken first give us four factors concerning conversational impressions of “focus
group interviews (FGIs)”: conversational activeness, conversational sequencing, the attitudes of participants and the relationships
of participants. In relation to the factors of conversational activeness and conversational sequencing in particular, the
microanalysis of four selected topical scenes from our database further shows that the behavior of the moderator and the interviewees
is organized not independently but with reference to each other. The study thus emphasizes the importance of the integration
of quantitative and qualitative approaches towards human interactions.
