The design-by-adaptation approach to universal access: learning from videogame technology

This paper proposes an alternative approach to the design of universally accessible interfaces to that provided by formal design frameworks applied ab initio to the development of new software. This approach, design-byadaptation, involves the transfer of interface technology and/or design principles from one application domain to another, in situations where the recipient domain is similar to the host domain in terms of modelled systems, tasks and users. Using the example of interaction in 3D virtual environments, the paper explores how principles underlying the design of videogame interfaces may be applied to a broad family of visualization and analysis software which handles geographical data (virtual geographic environments, or VGEs). One of the motivations behind the current study is that VGE technology lags some way behind videogame technology in the modelling of 3D environments, and has a less-developed track record in providing the variety of interaction methods needed to undertake varied tasks in 3D virtual worlds by users with varied levels of experience. The current analysis extracted a set of interaction principles from videogames which were used to devise a set of 3D task interfaces that have been implemented in a prototype VGE for formal evaluation

Towards virtual communities on the Web: Actors and audience

We report about ongoing research in a virtual reality environment where visitors can interact with agents that help them to obtain information, to perform certain transactions and to collaborate with them in order to get some tasks done. Our environment models a theatre in our hometown. We discuss attempts to let this environment evolve into a theatre community where we do not only have goal-directed visitors, but also visitors that that are not sure whether they want to buy or just want information or visitors who just want to look around. It is shown that we need a multi-user and multiagent environment to realize our goals. Since our environment models a theatre it is also interesting to investigate the roles of performers and audience in this environment. For that reason we discuss capabilities and personalities of agents. Some notes on the historical development of networked communities are included

The perception of emotion in artificial agents

Given recent technological developments in robotics, artificial intelligence and virtual reality, it is perhaps unsurprising that the arrival of emotionally expressive and reactive artificial agents is imminent. However, if such agents are to become integrated into our social milieu, it is imperative to establish an understanding of whether and how humans perceive emotion in artificial agents. In this review, we incorporate recent findings from social robotics, virtual reality, psychology, and neuroscience to examine how people recognize and respond to emotions displayed by artificial agents. First, we review how people perceive emotions expressed by an artificial agent, such as facial and bodily expressions and vocal tone. Second, we evaluate the similarities and differences in the consequences of perceived emotions in artificial compared to human agents. Besides accurately recognizing the emotional state of an artificial agent, it is critical to understand how humans respond to those emotions. Does interacting with an angry robot induce the same responses in people as interacting with an angry person? Similarly, does watching a robot rejoice when it wins a game elicit similar feelings of elation in the human observer? Here we provide an overview of the current state of emotion expression and perception in social robotics, as well as a clear articulation of the challenges and guiding principles to be addressed as we move ever closer to truly emotional artificial agents

Open Source Virtual Worlds and Low Cost Sensors for Physical Rehab of Patients with Chronic Diseases

For patients with chronic diseases, exercise is a key part of rehab to deal better with their illness. Some of them do rehabilitation at home with telemedicine systems. However, keeping to their exercising program is challenging and many abandon the rehabilitation. We postulate that information technologies for socializing and serious games can encourage patients to keep doing physical exercise and rehab. In this paper we present Virtual Valley, a low cost telemedicine system for home exercising, based on open source virtual worlds and utilizing popular low cost motion controllers (e.g. Wii Remote) and medical sensors. Virtual Valley allows patient to socialize, learn, and play group based serious games while exercising

Intellectual Property Rights in Virtual Environments: Considering the Rights of Owners, Programmers and Virtual Avatars

A virtual environment is a computer-generated world that can be used for training, data visualization, recreation, and commerce. The visitors of virtual environments include not only humans but also virtual avatars. The avatars can take on a range of shapes, characteristics, and personalities, and can perform a variety of tasks within the virtual environment. As the behavior of avatars becomes more realistic, sophisticated and intelligent- and the avatars become more autonomous in their decision making, the question of whether virtual avatars should have legal rights separate from those of their owner, becomes an issue. This paper discusses legal rights associated with the design and use of virtual avatars, commenting on the ownership rights of the creators of virtual avatars and the rights of avatars themselves should they gain intelligence and become independent decision makers and creators of intellectual property

Intellectual Property Rights in Virtual Environments: Considering the Rights of Owners, Programmers and Virtual Avatars

An emerging issue in online role-playing games is whether the licensor or participant owns the virtual property (such as a virtual avatar) created while the game is being played...Such rights have real world consequences for the objects created in the virtual world...Commercial software has been designed to allow people to create their own interactive, emoting 3D avatar using photographs of their individual faces, and their own unique voice as templates...Virtual environments can be designed for single inhabitants, such as a solo flight trainee, or for many, simultaneous participants... Further, people who spend significant amounts of time in virtual environments are doing more than playing video games...A major event in U.S. corporate law was the landmark Supreme Court decision to treat corporations as “persons” entitled to the equal protection of the laws under the 14th Amendment. Will there also be a similar landmark case for virtual avatars, or, as necessity dictates, will rights for avatars appear slowly without any particular landmark decision paving the way for their emancipation. Many questions remain unanswered, as there is literally no case law on the rights of artificially intelligent entities in general, and intelligent avatars specifically. However, given the increasing intelligence of avatars, significant legal disputes involving their actions very likely will arise in the future. This article provided a framework in which to consider how future litigation may develop, and potential causes of action which may be raised
