With the widespread deployment of broadband connections worldwide, software development and maintenance are increasingly being performed by multiple engineers, often working around-the-clock to maximize code churn rates. To ensure rapid quality assurance ...

An essential aspect of mobile and ubiquitous computing research is evaluation within the expected usage context, including environment. When that environment is an urban center, it can be dynamic, expansive, and unpredictable. Methodologies that focus ...

We present a service providing real-time feedback to participants of small group meetings on the social dynamics of the meeting. The service measures and visualizes properties of participants' behaviour that are relevant to the social dynamics of the ...

This study is motivated by the increased need to understand human response to video-links, 3G telephony and avatars. We focus on response of participants to audiovisual presentations of talking heads, and examine the effect of noise and temporal misalignment ...

We have implemented an experimental test development environment (TDE) intended to raise the effectiveness of tests produced for GUI systems, and raise the productivity of the GUI system tester.The environment links a test designer, a test design library, ...

Using role play at every stage of the design process has been a vital tool for IDEO in working with clients and users. With the dual properties of bringing participants into the moment and making shared activities physical rather than just mental, role ...

A challenge to individuals with cognitive impairments in wayfinding is how to remain oriented, recall routines, and travel in unfamiliar areas in a way relying on limited cognitive capacity. According to psychological model of spatial navigation and ...

Fifty-six teachers, from four European countries, were interviewed to ascertain their attitudes to and beliefs about the Collaborative Learning Environments (CLEs) which were designed under the Innovative Technologies for Collaborative Learning Project. ...

Website authentication technologies attempt to make the identity of a website clear to the user, by supplying information about the identity of the website. In practice however, usability issues can prevent users from correctly identifying the websites ...

This paper describes the influence of eye blinks on frequency analysis and power spectrum difference for task-evoked pupillography and eye-movement during an experiment which consisted of ocular following tasks and oral calculation tasks with three levels ...

This work explores the use of ambient displays in the context of interruption. A multimodal interface was created to communicate with users by using two ambient channels for interruption: heat and light. These ambient displays acted as external interruption ...

We consider a multi-rate loss system where two types of non-peak allocated traffic flows receive service. Both elastic and adaptive flows are associated with a peak-and a minimum bandwidth requirement and they tolerate bandwidth compression ...

In this paper, we describe a new concept about a virtual environment on networked computers to support distributed collaborative work. We focus explicitly on tools to enable informal (casual) communications in contrast to most of the existing ...

PageLinker is a browser extension that allows to contextualise navigation by linking web pages together and to navigate through a network of related web pages without prior planning. The design is based on extensive interviews with biologists, which ...

With the growing popularity of the Internet, there is an increasing demand to deliver continuous media (CM) streams over the Internet. However, packets may be damaged or lost during transmission over the current Internet. In particular, periodic network ...

Master Usability Scaling (MUS) is a measurement method for developing a universal usability continuum based on magnitude estimation and master scaling. The universal usability continuum allows true ratio comparisons, potentially between all items measurable ...
