A gap exists between the growing prevalence of peripheral displays and appropriate methods for their evaluation. Mankoff et al. [11] present one attempt to bridge this gap by adapting Nielsen's Heuristic evaluation to the defining characteristics and goals of peripheral displays. In this paper, we present a complementary approach that depends on active user(More)
The Americans with Disabilities Act (ADA), and Sections 504 and 508 of the Rehabilitation Act, prohibit discrimination against people with disabilities in all aspects of daily life, including education, work, and access to places of public accommodations. Increasingly, these antidiscrimination laws are used by persons with disabilities to ensure equal(More)
Ada is an entertainment exhibit that is able to interact with many people simultaneously, using a language of light and sound. " She " received 553,700 visitors over 5 months during the Swiss Expo.02 in 2002. In this paper we present the broad motivations, design and technologies behind Ada, and a first overview of the outcomes of the exhibit. Ada is an(More)
While one can characterize deep and shallow models at a high level of abstraction and contrast their relative merits in a general way, this provides little direction for knowledge engineering. In particular, the field lacks a clear definition of 'knowledge depth' and lacks guidelines regarding the appropriate depth of models for a given application, in this(More)
Do democracies make more effective coercive threats? An influential literature in international relations argues that democratic institutions allow leaders to credibly signal their resolve in crises, thereby making their threats more likely to work than threats by nondemocracies+ This article revisits the quantitative evidence for this proposition, which we(More)
Biomass from cellulosic bioenergy crops is expected to play a substantial role in future energy systems, especially if climate policy aims at stabilizing greenhouse gas concentration at low levels. However, the potential of bioenergy for climate change mitigation remains unclear due to large uncertainties about future agricultural yield improvements and(More)

While much is now known about the operation and organisation of the brain at the neuronal and microcircuit level, we are still some way from understanding it as a complete system from the lowest to the highest levels of description. One way to gain such an integrative understanding of neural systems is to construct them. We have built the largest(More)
Despite the prominence of the disability civil rights model--with its values of inclusion and empowerment--the majority of social and policy research conducted to date has not sufficiently included the perspective of persons with disabilities in the research process and as uniquely qualified researchers themselves. This article describes a new project,(More)
Despite immense progress in neuroscience, we remain restricted in our ability to construct autonomous, behaving robots that match the competence of even simple animals. The barriers to the realisation of this goal include lack of knowledge of system integration issues, engineering limitations and the organisational constraints common to many research(More)
