During a dyadic social interaction, two individuals can share visual attention through gaze, directed to each other (mutual gaze) or to a third person or an object (joint attention). Shared attention is fundamental to dyadic face-to-face interaction, but how attention is shared, retained, and neutrally represented in a pair-specific manner has not been well studied. Here, we conducted a two-day...

We present an open-source, gaze-controlled adaptation of the well-known Breakout computer game. In a tournament where 20 subjects took turns playing this game against each other, one using gaze and one using a mouse, we demonstrate that gaze can be a superior input modality. In another experiment, we collected eye movement data from 9 subjects playing this game and find that expert and novice p...

Finally, these same-aged children would be expected to solve distance inference problems based on either time or velocity information depending on which is more salient. Therefore, future research should include younger children and manipulate the salience of velocity and time information in the distance inference task. Third, if the task demands of velocity inferences were reduced, it is predi...

Our question answering system was built with a number of priorities in mind. First, we wanted to experiment with natural language processing (NLP) technologies such as shallow parsing, named entity tagging, and coreference chaining. We felt that the small number of terms in the questions coupled with the short length of the answers would make NLP technologies clearly beneficial, unlike previous...

2 Principal contact: This year our primary goal was to improve on the performance of our TREC-8 system. In addition to improving the system directly, we worked on a number of tools to aid our development. We continued our work on a tool for automatic scoring of system responses, a “judge” program. We designed a tool for doing regression testing of question answering systems. W...

In this paper we summarize the current state of the development of SYS/3 (SYStematic SYStem Development SYStem), the main features of the system and further research. SYS/3 assists in developing software systems according to a pre-stated standard and assures proper quality of software during its entire life-cycle. A software is considered a set of system connguration items called documents. SYS...

OBJECTIVE Non-invasive diagnosis of rejection is a major objective in the management of heart transplant recipients. The ability of strain rate (SR) imaging on echocardiograms to detect rejection in heart transplant recipients was investigated. METHODS A total of 396 endomyocardial biopsies, right-heart catheterisation and echocardiograms were performed in 35 heart transplant recipients. Mean...

T h is paper introduces a human centered expert sys tem for des ign and improvement of s trategic planning in a manufacturer of cons truction products . The development process of the expert sys tem is facilitated through knowledge base, learning module, inference engine, description tools and usability tes ting and inspection. To achieve the above objective, all indigenous and exogenous factor...

C. elegans SYS-1 has key functional characteristics of a canonical beta-catenin, but no significant sequence similarity. Here, we report the SYS-1 crystal structure, both on its own and in a complex with POP-1, the C. elegans TCF homolog. The two structures possess signature features of canonical beta-catenin and the beta-catenin/TCF complex that could not be predicted by sequence. Most importa...
