Joking, storytelling, artsharing, expressing affection: a field trial of how children and their social network communicate with digital images in leisure time

Increasing use of mobile phones in leisure and communication with digital images are important and current issues in the field of telecommunications. However, little is known about how images would be used in leisure related communication. According to our experience field trials are the best way of studying it. In this paper, we describe a field-trial case study of leisure related communication with digital images. Moreover, we discuss the advantages of conducting field trials as part of product concept design process.

Paper prototyping - what is it good for?: a comparison of paper- and computer-based low-fidelity prototyping

This study investigated the differences between computer-based and paper-based low-fidelity prototypes. It researched whether subjects confronted with these two kinds of prototypes differ in their willingness to criticize a system and to give suggestions for its improvement. The chosen approach was an empirical study including test sessions using both kinds of prototypes. Quantitative and qualitative methods were applied to measure and to explain possible differences.

Usability evaluations for multi-device application development three example studies

This paper discusses three example studies, that informed user interface guidelines, developed for a set of different classes of mobile devices. The results of these studies show answers to typical design problems arising during the development of mobile applications. Furthermore the studies are meant to be examples showing which kind of studies are required in order to develop a sufficient pool of user interface guidelines covering almost all sorts of mobile devices.

The gear model of HCI education

Gears are used as central metaphor for the philosophy of a coordinated HCI education program. The program consists of six parts distributed over one year. The main emphasis of all parts is on active involvement with a considerable amount of feedback and reflection.

Java based user interface design and development

The objective of this tutorial is to introduce the Java platform from a design rather then from a programming perspective. It provides an exploration of key issues of the Java technology necessary to create high quality and novel web technology based application environments. Based on the experience of several Java based user interface projects the specific needs of usability engineers will be addressed. User interface potentials embedded in the Java platform will be uncovered.

Multichannel-Usability — Faktor Mensch bei der Gestaltung

Derzeit (noch) alternative Arbeitskonzepte wie Teleworking oder im allgemeinen Sinne Remote Working konnten in Zukunft von immer mehr Arbeitnehmern in Anspruch genommen werden. So ist der Anteil an Arbeitnehmern, die zumindest Teile ihrer Arbeitsleistung nicht im Firmenburo erbringen, in den letzten Jahren kontinuierlich um ca. 15% jahrlich gestiegen. [1]

Making usability engineering happen: Center for Usability Research & Engineering (CURE)

CURE is an usability organization active in a variety of national and international initiatives and projects. The whole usability engineering cycle is covered and a wide range of application domains is supported. In particular the integration of usability engineering in day to day development is a major challenge.
