    Semantics for Intuitionistic Arithmetic Based on Tarski Games with Retractable Moves

    Abstract. We define an effective, sound and complete game semantics for HAinf, Intuitionistic Arithmetic with ω-rule. Our semantics is equivalent to the original semantics proposed by Lorentzen [6], but it is based on the more recent notions of ”backtracking ” ([5], [2]) and of isomorphism between proofs and strategies ([8]). We prove that winning strategies in our game semantics are tree-isomorphic to the set of proofs of some variant of HAinf, and that they are a sound and complete interpretation of HAinf. 1 Why game semantics of Intuitionistic Arithmetic? In [7], S.Hayashi proposed the use of an effective game semantics in his Proof Animation project. The goal of the project is ”animating” (turning into algorithms) proofs of program specifications, in order to find bugs in the way a specification is formalized. Proofs are formalized in classical Arithmetic, and the method chosen for “animating ” proofs i

    Designing Affective Loop Experiences

    There is a lack of attention to the emotional and the physical aspects of communication in how we up to now have been approaching communication between people in the field of Human Computer Interaction (HCI). As de-signers of digital communication tools we need to consider altering the un-derlying model for communication that has been prevailing in HCI: the in-formation transfer model. Communication is about so much more than trans-ferring information. It is about getting to know yourself, who you are and what part you play in the communication as it unfolds. It is also about the experience of a communication process, what it feels like, how that feeling changes, when it changes, why and perhaps by whom the process is initiated, altered, or disrupted. The idea of Affective Loop experiences in design aims to create new expressive and experiential media for whole users, embodied with the social and physical world they live in, and where communication not only is about getting the message across but also about living the experi-ence of communication- feeling it. An Affective Loop experience is an emerging, in the moment, emotional experience where the inner emotional experience, the situation at hand and the social and physical context act together, to create for one complete em-bodied experience. The loop perspective comes from how this experience takes place in communication and how there is a rhythmic pattern in com-munication where those involved take turns in both expressing themselves and standing back interpreting the moment. To allow for Affective Loop experiences with or through a computer system, the user needs to be allowed to express herself in rich personal ways involv-ing our many ways of expressing and sensing emotions – muscles tensions, facial expressions and more. For the user to become further engaged in inter-action, the computer system needs the capability to return relevant, either diminishing, enforcing or disruptive feedback to those emotions expressed by the user so that the she wants to continue express herself by either strengthening, changing or keeping her expression. We describe how we used the idea of Affective Loop experiences as a con-ceptual tool to navigate a design space of gestural input combined with rich instant feedback. In our design journey, we created two systems, eMoto and FriendSense

    Scaling up: Achieving a breakthrough in adult learning with technology

    Get PDF
    The first report commissioned by Ufi Charitable Trust. It investigates opportunities for and barriers to the application of digital technology to adult learning. It focuses on possible ways to transform the UK’s vocational education and training system, identifying three main priorities for funding by the Ufi Charitable Trust: * increasing the capability of those involved in running the vocational learning system * exploiting networks to bring together learners, learning content and learning professionals * harnessing computers to support individualised and differentiated learning
