    We explore some of the characteristics of multimodal input interaction spaces for notification systems within a multi-tasking environment like a command and control center using two promising interaction methods: gestures and touch based input through a laboratory experiment comparing both techniques. Results of our study suggest that gestures are better suited for multi-tasking situations because... View full abstract»

    Clustering algorithms are the core technique of data mining, machine learning, pattern matching, bioinformatics and a number of other fields. This paper proposes a new clustering method based on attribute partitioning and a novel data visualization method. In a nutshell, the idea for our method is based on two steps: 1) cluster data set using primary and secondary attributes of data; 2) map color ... View full abstract»

    In today's continuously changing markets newly developed products often do not meet the demands and expectations of customers. Research on this problem identified a large gap between developer and user expectations. Approaches to bridge this gap are to provide the developers with better information on product usage and to create a fast feedback cycle that helps tackling usage problems. Therefore, ...

    We present a fully automated three-dimensional model-based, real-time capable approach to distinguish six universal facial expressions from visual images of human faces. The face model is fitted to the images of a publicly available data base. From the model parameters two sets of features are computed, person-specific and non-person-specific to estimate the facial expression visible in the curren... View full abstract»

    Device-assisted navigation is rapidly becoming a major topic in computer science. PDAs and other small devices are enabling the introduction of navigational assistants to many different spaces. These areas are generally filled with points of interest with which users may choose to interact with. The natural behavior of users in such a space is to explore, interacting with objects the user deems wo... View full abstract»

    The main problem for generating an extractive automatic text summary is to detect the most relevant information in the source document. For such purpose, recently some approaches have successfully employed the word sequence information from the self-text for detecting the candidate text fragments for composing the summary. In this paper, we employ the so-called n-grams and maximal frequent word se... View full abstract»

    An important issue when evaluating a search tool is the satisfaction that is expressed by its users. While there are many factors that affect satisfaction, we believe that users' expectations affect their evaluation of a query's response, and in turn, their satisfaction. We validate this perspective by measuring individuals' expectation, judgement of response quality, and overall satisfaction for ... View full abstract»

    We are interested in whether humans create a model of their partner when they jointly manipulate an object in a virtual task without haptic feedback. In such a scenario the partner is perceived as a disturbance because she/he is responsible for inconsistencies between the visual and proprioceptive feedback of the individual. To gain basic knowledge on the predictability of such disturbances we com... View full abstract»

    To better understand motion perception in immersive virtual environments, we conducted a user study to quantify perception of scene motion as subjects yawed their heads. We measured psychometric functions of scene-velocity thresholds for different head motions and then extracted 75% thresholds, creating scene-velocity thresholds as functions of three measures of head motion: 1) angular range, 2) p...

    Given its current state of the art, model-based UI development (MBDUI) is able to fulfill the major requirements of desktop and mobile applications, such as form-based user interfaces that adapt to the actual context of use. More recent research deals with the development of 3D interactive multimodal environments. Though user-centered design is more and more driving the design of these environment... View full abstract»

    As a consequence of various situational and personal factors, programmers use a variety of styles when performing software development and maintenance tasks. In this paper, we develop a contextual framework that links situational, task-oriented, and individual factors to a set of traits. These traits are expressed as behavioural modifiers, and thus, influence one's performance of tasks such as com... View full abstract»

    Human interaction like entering some data, making decisions etc. has to be dealt with as an integral part of today's business processes and the supporting IT likewise. Hence, human interaction leads to an increased complexity in software development and software systems. Current business- and model-driven development approaches provide promising means to deal with this complexity. Diverse aspects ... View full abstract»

    An incoming freshman student stops by your office because he/she has read that your research area is HCI and desires to work with you. As teachers and academic advisers, how should we assist our students in choosing courses that will be beneficial to their study of HCI, but that will also provide the breadth that undergraduate studies provide? How should we as researchers assist our students in de... View full abstract»
