1 The present research is mostly achieved in the framework of the art.live project (http://www.tele.ucl.ac.be/projects/art.live). This project is part of the 5th framework programme of the European Commission: Information Society Technologies (IST, project #10942). Abstract: Intuitive movements in front of a mirror are banal. Replacing the mirror by a screen showing a similar mirrored image, bu...

This article presents ISEE, an intuitive sound editing environment, as a general sound synthesis model based on expert auditory perception and cognition of musical instruments. It discusses the backgrounds of current synthesizer user interface design and related timbre space research. Of the three principal parameters of sound—pitch, loudness and timbre—ISEE focuses on control of timbre, and af...

A color-picker or color-selection tool is part of a GUI that allows users to select colors for use in software applications. There is a widespread belief that some color spaces or models are more “natural” than others. However, this intuitively appealing idea that a color space based on the nature of color perception (such as HSL) may be preferable to one that is driven by the nature of the tec...

A substantial body of evidence indicates that utilitarian judgments (favoring the greater good) made in response to difficult moral dilemmas are preferentially supported by controlled, reflective processes, whereas deontological judgments (favoring rights/duties) in such cases are preferentially supported by automatic, intuitive processes. A recent neuroimaging study by Kahane et al. challenges...

This article is divided into two parts. In the first part we present a general theory of the dyadic lattices. In the second part we show several applications of this theory to harmonic analysis: a decomposition of an arbitrary measurable function in terms of its local mean oscillations, and a pointwise bound of CalderónZygmund operators by sparse operators. Table of

This paper treats the pathfinding of autonomous agents from a given start point to a set of targets. It mainly focuses on continuous domains with continuous state and action spaces of the agents. In these continuous domains a technique called Cross Entropy Online Planning can be deployed by the agents to plan and assess sequences of actions in order to reach their goals. However, this technique...

Kommt intuitive Benutzbarkeit als übergeordnetes Usability-Ziel infrage? Wenn ja, unter welchen Bedingungen? Wie wird geprüft, ob das Ziel erreicht wurde? Nach einer Klärung des Konzepts wird die Frage bearbeitet, inwiefern sich intuitive Benutzbarkeit mit dem UsabilityQualitätsmodell der ISO 9241-Serie vereinbaren lässt. Abschließend werden Implikationen der vorgestellten Überlegungen für den ...

By a graph, a mathematician generally means a collection of points (vertices) and a list indicating how they are connected (a collection of edges). The study of graphs and their properties is a huge industry, with applications from the completely abstract (e.g. classification of algebras) to the very applied (e.g. network routing). The simplest type of graph, and the only type which I’ll consid...

Formal countermodels may be used to justify the unprovability of formulae in the Heyting calculus (the best accepted formal system for constructive reasoning), on the grounds that unprovable formulae are constructively invalid. We argue that the intuitive impact of such countermodels becomes more transparent and convincing as we move from Kripke/Beth models based on possible worlds, to Läuchli ...

This thesis examines the role of intuition in the way that people operate unfamiliar devices, and the importance of this for designers. Intuition is a type of cognitive processing that is often non-conscious and utilises stored experiential knowledge. Intuitive interaction involves the use of knowledge gained from other products and/or experiences. Therefore, products that people use intuitivel...
