Chapter
In this paper, we present a methodology on how to implement multimodal voice controlled systems by means of automatic speech recognition. The real flight deck environment brings many challenges such as high accuracy requirements, high noise conditions, non-native English-speaking users or limited hardware and software resources. We present the desi...
Article
Evolutionary music composition refers to machine-based generation of musical pieces by means of evolutionary computation techniques. In this chapter we discuss machine-based music composition from several viewpoints. First, techniques used to machine-based music composition are reviewed. Second, music composition subtasks, such as generating melodi...
Chapter
This chapter provides a review of methods for automatic modularization of programs evolved using genetic programming. We discuss several techniques used to establishing modularity in program evolution, including highly randomized techniques, techniques with beforehand specified structure of modules, techniques with evolvable structure and technique...
Article
Autonomous evaluation of computer generated musical pieces remains one of the most challenging open problems in evolutionary music composition. This paper introduces the design of novel mutation and fitness operators for autonomous evolution of human-competitive rhythm accompaniment using genetic algorithm. We propose several fitness operators that...
Chapter
Enterprise Resource Planning (ERP) systems had grown into complex applications integrating various processes and large amounts of data in detail. Such complexity negatively impacts usability owing to providing single static user interface that should meet users with diverse roles, tasks and requirements. In this paper we introduce a concept of adap...
Conference Paper
This paper introduces novel approach to logging user activity in software applications that provide accurate high-level information about issued commands, commands parameters and user interaction styles without a need for inferring user activity from logged user interfaces events as it is required on most loggers these days. We also demonstrate the...
Conference Paper
An analysis was conducted to evaluate the differences between users in utilization of functionality and interaction styles in word processing applications. The study evaluated 117 users of various word processing applications using a questionnaire. Results show that differences between users in used functionality are considerable. The differences i...
Conference Paper
We introduce novel fine-grained adaptive user interface for the OpenOffice.org Writer word processor. It provides a panel container with personalized user interface to an individual user. The personalization is provided on frequently or recently used user commands, user’s preferred interaction styles and frequently used parameters to user commands....
Conference Paper
This paper introduces particular results on analysis of usage patterns in contemporary word processing applications. We evaluate how interaction styles are used accordingly to frequency of usage of underlying user commands or semantical categories of user commands. We show that menus are used as a prevalent interaction style and report usage patter...
Conference Paper
We introduce a research framework which enables to use the OpenOffice.org as a platform for HCI research, particularly for performing user studies or prototyping and evaluating intelligent user interfaces. We make two contributions: (1) we introduce an innovative hybrid logging technique which provides high-level, rich and accurate information abou...
Article
Modern graphical user interfaces are based on the WIMP (Window, Icon, Menu, Pointing device) paradigm which has been introduced around 1980 and used without any dramatic change until today. In 2007, Microsoft introduced the Ribbon: a radically redesigned user interface for the Office suite as a reaction to increasing complexity of the Office suite...
Article
This paper introduces a multi objective function based approach for evolving programs with emphasis on modularity and repetitive code execution. A functional paradigm based programming language for evolution of programs is presented. The evolution of recursive functions using code structure abstraction is discussed henceforward and a kind of struct...
Article
This article introduces an application of higher order functions as structure abstractions of recursive1 functions as a method to reduce a search effort needed for the automatic programming (evolving) of common types of recursive functions. We will shortly describe a functional paradigm based language specially designed for automatic programming. H...
Article
This article introduces a genetic algorithm based system intended for automated generating of a realistic rhythmic (drum set) accompaniment. Present systems do not insist on the natural music criteria and realistic (human-like) result. They generate a rhythmic accompaniment regardless to the other instruments used. The fitness operators are mostly...
