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.

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.

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.

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.

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.

To get the maximum benefit from ambient intelligence (AmI), we need to anticipate and react to possible drawbacks and threats
emerging from the new technologies in order to devise appropriate safeguards. The SWAMI project took a precautionary approach
in its exploration of the privacy risks in AmI and sought ways to reduce them. It constructed four “dark scenarios” showing
possible negative implications of AmI, notably for privacy protection. Legal analysis of the depicted futures showed the shortcomings
of the current legal framework in being able to provide adequate privacy protection in the AmI environment. In this paper,
the authors, building upon their involvement in SWAMI research as well as the further advancement of EU privacy analysis,
identify various outstanding issues regarding the legal framework that still need to be resolved in order to deal with AmI
in an equitable and efficacious way. This article points out some of the lacunae in the legal framework and postulates several
privacy-specific safeguards aimed at overcoming them.

This viewpoint argues that the introduction of most computer-based system to an organization transforms the organization and
changes the work patterns of the system’s users in the organization. These changes interact with the users’ values and beliefs
and trigger emotional responses which are sometimes directed against the software system and its proponents. A requirements
engineer must be aware of these emotions.

LuxTrace: indoor positioning using building illumination 总被引:1,自引:1,他引:0
Julian Randall Oliver Amft Jürgen Bohn Martin Burri 《Personal and Ubiquitous Computing》2007,11(6):417-428
Tracking location is challenging due to the numerous constraints of practical systems including, but not limited to global
cost, device volume and weight, scalability and accuracy; these constraints are typically more severe for systems that should
be wearable and used indoors. We investigate the use of wearable solar cells to track changing light conditions (a concept
that we named LuxTrace) as a source of user displacement and activity data. We evaluate constraints of this approach and present
results from an experimental validation of displacement and activity estimation. The results indicate that a distance estimation
accuracy of 21 cm (80% quantile) can be achieved. A simple method to combine LuxTrace with complementary absolute location
estimation methods is also presented. We apply carpet-like distributed RFID tags to demonstrate online learning of new lighting
environments.

Protecting business intelligence and customer privacy while outsourcing data mining tasks 总被引:1,自引:1,他引:0
Nowadays data mining plays an important role in decision making. Since many organizations do not possess the in-house expertise
of data mining, it is beneficial to outsource data mining tasks to external service providers. However, most organizations
hesitate to do so due to the concern of loss of business intelligence and customer privacy. In this paper, we present a Bloom
filter based solution to enable organizations to outsource their tasks of mining association rules, at the same time, protect
their business intelligence and customer privacy. Our approach can achieve high precision in data mining by trading-off the
storage requirement.

We provide the complete record of methodology that let us evolve BrilliAnt, the winner of the Ant Wars contest. Ant Wars contestants are virtual ants collecting food on a grid board in the presence
of a competing ant. BrilliAnt has been evolved through a competitive one-population coevolution using genetic programming
and fitnessless selection. In this paper, we detail the evolutionary setup that lead to BrilliAnt’s emergence, assess its
direct and indirect human-competitiveness, and describe the behavioral patterns observed in its strategy.

Wealth adjustment using a synergy between communication, cooperation, and one-fifth of wealth variables in an artificial society 总被引:1,自引:0,他引:1
Wealth distribution based on classic sugarscape model leads to a population increase and the Gini coefficient decrease when
cooperation and communication parameters are taken into account. In another study, this model was developed by implying a
receipt of one-fifth of the assets of the population and derived utilization for poor people. The results showed a relation
between mortality decrease, population increase, and Gini coefficient decrease (equality increase). In a synergic process,
the wealth adjustment based on sugarscape model underwent some experiments by implying communication and cooperation, and
the mechanism of receiving and utilizing the assets. The results show that the population increase and the Gini coefficient
decrease play an important role in wealth adjustment.

The quality of software systems are determined in part by their optimal configurations. Optimal configurations are desired
when the software is being deployed and during its lifetime. However, initial deployment and subsequent dynamic reconfiguration
of a software system is difficult because of the interplay of many interdependent factors, including cost, time, application
state, and system resources. As the size and complexity of software systems increases, procedures (manual or automated) that
assume a static software architecture and environment are becoming untenable. We have developed a novel technique for carrying
out the deployment and reconfiguration planning processes that leverages recent advances in the field of temporal planning.
We describe a tool called Planit, which manages the deployment and reconfiguration of a software system utilizing a temporal
planner. Given a model of the structure of a software system, the network upon which the system should be hosted, and a goal
configuration, Planit will use the temporal planner to devise possible deployments of the system. Given information about
changes in the state of the system, network and a revised goal, Planit will use the temporal planner to devise possible reconfigurations
of the system. We present the results of a case study in which Planit is applied to a system consisting of various components
that communicate across an application-level overlay network.

In this article we present an engineering approach for the integration of social group dynamics in the behavior modeling of
multiagent systems. To this end, a toolbox was created that brings together several theories from the social sciences, each
focusing on different aspects of group dynamics. Due to its modular approach, the toolbox can either be used as a central
control component of an application or it can be employed temporarily to rapidly test the feasibility of the incorporated
theories for a given application domain. This is exemplified by applying the toolbox to different applications.

One of the tropes of the age of ubiquitous computing is the migration of computation into new spaces. Domestic environments
have been a particular focus of attention for many. However, these spaces are neither empty nor neutral. They are already
populated by people and practices which shape both their physical form and cultural meaning. We want to consider here some
questions of technology and domesticity. In order to give some critical perspective, we want to approach domestic space from
the edge, and in particular, from the shed.

The effect of Internet use as a mediating variable on self-efficacy as it relates to the cognition of network-changing possibility
(i.e., connecting people or groups with different social backgrounds) was examined. The results showed that Internet use (i.e.,
the frequency of sending e-mail, friends made on the Internet) had a positive effect on the cognition of network-changing
possibility. The cognition that it is possible to connect people with different social backgrounds by using the Internet also
had a positive effect on self-efficacy. On the other hand, the cognition that it is possible to find people or groups who
share beliefs and interests by using the Internet negatively affected self-efficacy. Hence, it was found that the effect of
Internet use on self-efficacy was different as a function of cognition of network-changing possibility.
