    The invention concerns an interaction area with image processing for the objects to be detected at the perception area. The objects are in contrast in the perception area and thus can be easily recognized by the image processing

    An analysing and modelling tool kit for human-computer interaction

    Get PDF
    A tool kit has been developed to analyze the empirical data of the interactive task solving behaviour described in a finite discrete state space (e.g., human-computer interaction), helping the human factors engineer to design a good interactive system. The observable sequences of decisions and actions produced by users contain much information about: the mental model of the user; the individual problem solving strategies for a given task; and the underlying decision structure. AMME (Automatic Mental Model Evaluator) tool kit, handles the recorded decision and action sequences and automatically provides: an extracted net description of the task dependent device model; a complete state transition matrix; and different quantitative measures of the decision behaviou

    BUILD-IT: an intuitive design tool based on direct object manipulation

    Natural interaction, in the context of this paper, means human action in a world of tangible objects and live subjects. We introduce the concept of action regulation and relate it to observable human behaviour. A tool bringing together motor and cognitive action is a promising way to assure complete task regulation. Aiming for such tools, we propose a set of guidelines for the next generation of user interfaces, the Natural User Interface (NUI). We present a NUI instantiation called BUILD-IT, featuring video-mediated interaction in a task specific context. This multi-brick interaction tool renders virtual objects tangible and allows multiple user simultaneous interaction in one common space. A few user experiences are briefly describe

    Design Methods for Interactive TV : two empirical studies

    Get PDF
    The central question for this paper is how to improve the production process by closing the gap between industrial designers and software engineers of television(TV)-based User Interfaces (UI) in an industrial environment. Software engineers are highly interested whether one UI design can be converted into several fully functional UIs for TV products with different screen properties. The aim of the software engineers is to apply automatic layout and scaling in order to speed up and improve the production process. However, the question is whether a UI design lends itself for such automatic layout and scaling. This is investigated by analysing a prototype UI design done by industrial designers. In a first requirements study, industrial designers had created meta annotations on top of their UI design in order to disclose their design rationale for discussions with software engineers. In a second study, industrial designers assessed the potential of four different meta annotation approaches. The question was which annotation method industrial designers would prefer and whether it could satisfy the technical requirements of the software engineering process. One main result is that the industrial designers preferred the method they were already familiar with, which therefore seems to be the most effective one although the main objective of automatic layout and scaling could still not be achieved

    Revolution in Manipulation Law: The New CFTC Rules and the Urgent Need for Economic and Empirical Analyses

    Three major banks have now admitted that their employees manipulated worldwide interest rates through the London Interbank Offered Rate (Libor), the most widely used interest rate index. Libor is the interest rate term for trillions of dollars of swaps and loans, and its manipulation may have been used to extract billions of dollars. These allegations come just as commodities manipulation law has been dramatically reformed and the Commodity Futures Trading Commission (CFTC) given vast new regulatory powers. This Article provides the first extended, scholarly analysis of the CFTC’s new anti-manipulation rules. We consider the difficulty the rules address: Commodities manipulation claims have traditionally faced nearly insuperable obstacles to success in prosecuting manipulations like that of Libor. We then analyze the new rules, including their extension of the CFTC’s powers to cover the swap market. The new rules appropriately lower the standards of pleading and proof, and yet the breadth of the new rules invites abuse. Both to implement the new rules and to prevent overuse, we argue for more elaborate, sophisticated, and creative economic analysis than ever before. We provide a wide-ranging overview of empirical tools for assessing manipulation claims, while re-engaging a decades-old debate on the place of empiricism in the laws of evidence and intent. We provide detailed examples of how manipulation screens are necessary to complete the Dodd-Frank Wall Street Reform and Consumer Protection Act’s (DoddFrank)’s revolution in manipulation law
