- Building on a compositional relational programming language Combilog, code visualization with a motivation of flexible practical applications is explored. Following from earlier work based on Higraph diagram formalizations, a new coloured and human perception-centric iteration of visual representation is introduced, and its effects on understanding compositional relational programs are analysed by means of a user study. Results showed that visuals helped participants to solve coderelated questions 46% faster with 69% less errors.

- We present a hand-and-foot-based multimodal interaction approach for handheld devices. Our method combines input modalities (i.e., hand and foot) and provides a coordinated output to both modalities along with audio and video. Human foot gesture is detected and tracked using contour-based template detection (CTD) and Tracking-Learning-Detection (TLD) algorithm. 3D foot pose is estimated from passive homography matrix of the camera. 3D stereoscopic and vibrotactile are used to enhance the immersive feeling. We developed a multimodal football game based on the multimodal approach as a proof-of-concept. We confirm our systems user satisfaction through a user study.

Robots and systems as autonomous ethical agents

Konferensbidrag (refereegranskat)abstract
- IT systems and robots can help us to solve many problems caused by the quantity, variation and complexity of information; because we need to handle dangerous and risky situations; or because of our social and emotional needs like elderly care. In helping us, these systems have to make decisions and act accordingly to achieve the goals for which they were built. Ethical decision support tools can be integrated into robots and other decision making systems to secure that decisions are made according to the basic theories of philosophy and to the findings of psychological research. This can be done, in non-independent systems, as a way for the system to report to its operator, and to support the operator's ethical decision making. On the other hand, fully independent systems should be able to regulate their own decision making strategies and processes. However, this cannot be based on normative predefined criteria, or on the ability to make choices, or on having own control, or on ability of rational processing. It seems that it is necessary for an independent robot or decision system to have "emotions." That is, a kind of ultimate purposes that can lead the decision process, and depending on the circumstances, guide the adoption of a decision strategy, whatever it may be, rational, heuristic or automatic.

Konferensbidrag (refereegranskat)abstract
- The ICT infrastructure and its technological core are now becoming the critical infrastructures of our society. Our activities and processes are now relying on these platforms, they are now our social and business platforms. But are they sustainable? What are the (physical) limits to take into account when looking into the ICT future? Do the planet have enough resources to sustain the making, powering and wasting of all the electronic devices needed to support our social and business platforms in the future? This paper addresses the issue of evaluating the environmental impact of ICT. Starting from the analysis of the sustainability of one of its most celebrated "laws", the Moore's law, we analyse its entire life-cycle, from "silicon-factories", to their use in data centres, to the final destination of ICT products: recycling and reuse (trash ware) in the best case or, uncontrolled waste traffic towards poor countries with health hazards and environmental pollution, in the worst case. We introduce a new dimension in the social and ethical analysis related to ICT: the future. What are the implications of this future ethics in ICT?

Konferensbidrag (refereegranskat)abstract
- The purpose with EthXpert is to help an analyst or decision maker to understand how different design solutions affect the interests of each involved stakeholder. To support this understanding, the analysis is made explicit by iterating a procedure comprising three main steps. The first step is to create an overview by drawing a stakeholder network, i.e. a map over the relations between all stakeholders. Second the impact of each stakeholder’s interests on other stakeholders are analyzed and noted. Finally the considerations for each interest are used as foundation for making assumptions about how the stakeholders are affected by different design solutions. Not only does this process help people to scrutinize, structure and get overview of an ethical problem. The resulting document can also be used as vindication of the choices that are made. Various ethical support systems have targeted the concern of identifying relevant information in different ways. EthXpert has been applied on the design of different IT systems with very positive results. With help from EthXpert the test groups were able to extend previous analyses through identifying additional stakeholders and interests. The procedure also gave insight in how the interests of different stakeholders were interrelated. Some of the test groups especially appreciated the collaboration feature of EthXpert. An ethical analysis often brings up many big and small issues to consider and it is therefore efficient if a group can cooperate in solving the problems. Thus the tool also works as a means to gather several perspectives on a problem. Through the explicit process, the designer acquires both a better overview of the complexity of a problem and a conception of how the involved stakeholders affect and are affected by different solutions. Almost all of the test subjects were of the opinion that the systematic procedure of EthXpert is purposeful for acquiring higher ethical problem-solving and decision-making skills by offering a holistic overview over ethical aspects in the design of IT systems. Although critical remarks about the usability of the interface, many also became aware of shortages in a prior analysis made without the tool. This indicates that a computerized tool that guides the investigation of stakeholders’ interests, and supports structuring and overview over information, is helpful for designing more ethical IT systems.

What are ethical agents and how can we make them work properly?

Konferensbidrag (refereegranskat)abstract
- To support ethical decision making in autonomous agents, we suggest to implement decision tools based on classical philosophy and psychological research. As one possible avenue, we present EthXpert, which supports the process of structuring and assembling information about situations with possible moral implications.
