Abstract—In order to examine user group differences in modality preferences, participants of either gender and two age groups have been asked to rate their experience after interact-ing with a smart-home system offering unimodal and multi-modal input possibilities (voice, free-hand gesture

Map places 554 subdisciplines on the surface of a sphere—those with papers that cite the same base knowledge are placed in closer proximity. The spheric layout is then flattened using a Mercator projection. Each node is labeled and has an extensive list of journal names and key phrases as metadata, which can be used to “science locate ” journal

to solve this mystery by defining different professional publisher groups, examining the behaviors of these user groups, and identifying the characteristics of their metadata use. This study will enhance the current understanding of metadata application behavior and provide evidence useful to researchers

Abstract: This paper presents the results of a web based survey assessing the usability of main uncertainty visualisation methods for users belonging to different key domains such as GIS and Climate change research. We assess the usability of the visualisation methods based on the user

are investigated in Izmir City, Turkey. The study focused on the transit users; considered information types for different transit mode segments were identified. In addition, accepted information types for non-transit users to consider transit as an alternative commute mode was investigated. For these purposes, a

In this work, algorithms are developed and evaluated to detect physical activities from data acquired using five small biaxial accelerometers worn simultaneously on different parts of the body. Acceleration data was collected from 20 subjects without researcher supervision or observation

masquerade detection. Furthermore, the performance of these methods on different types of users and masqueraders is analyzed. We explore what kind of users are easily distinguishable from others, and what kind of masqueraders are difficult to detect. Copyright c © 2010 John Wiley & Sons, Ltd.

Information technology (IT) acceptance research has yielded many competing models, each with different sets of acceptance determinants. In this paper, we (1) review user acceptance literature and discuss eight prominent models, (2) empirically compare the eight models and their extensions, (3

management. We formalize the notion of a secure group as a triple (U; K;R) where U denotes a set of users, K a set of keys held by the users, and R a user-key relation. We then introduce key graphs to specify secure groups. For a special class of key graphs, we present three strategies for securely

The original formulation of SharedPlans by B. Grosz and C. Sidner ( 1990) was developed to provide a model of collaborative planning in which it was not necessary for one agent to have intentions-to toward an act of a different agent. Unlike other contemporaneous approaches (J.R. Searle, 1990
