Revealed Preferences for Risk and Ambiguity

We replicate the essentials of the Huettel et al. (2006) experiment on choice under uncertainty with 30 Yale undergraduates, where subjects make 200 pair-wise choices between risky and ambiguous lotteries. Inferences about the independence of economic preferences for risk and ambiguity are derived from estimation of a mixed logit model, where the choice probabilities are functions of two random effects: the proxies for risk-aversion and ambiguity-aversion. Our principal empirical finding is that we cannot reject the null hypothesis that risk and ambiguity are independent in economic choice under uncertainty. This finding is consistent with the hypothesized independence of the neural mechanisms governing economic choices under risk and ambiguity, suggested by the double dissociation-fMRI study reported in Huettel et al.Mixed logit, Risk-aversion, Ambiguity-aversion

Use of video shadow for small group interaction awareness on a large interactive display surface

This paper reports work done as part of the Large Interactive Display Surface (LIDS) project at the University of Waikato. One application of the LIDS equipment is distributed meeting support. In this context large display surfaces are used as shared workspaces by people at collaborating sites. A meeting with start with a shared presentation document, typically and agenda document with summary and detail on agenda items as required. During the meeting, annotations with be made on the shared document, and new pages will be added with notes and drawings. To prevent access collisions and generally mediate use of the shared space, mechanisms to provide awareness of actions of people at other sites are required. In our system a web camera is used to capture a low-resolution image of the person/people near the board on each side. Rather than transmit the image directly we computed a shadow/silhouette. The shadow is displayed behind other screen content. This provides awareness of position and impending write actions and allows intentional pointing to locations of the screen. It also has the advantage of being transmitted with low bandwidth, being relatively insensitive to low frame rates, and minimizing visual interference with substantive data being displayed on the screen

Lecture capture using large interactive display systems

There are various software technologies that allow capture and redelivery of lectures. Most of these technologies however rely on the use of proprietary software, often requiring extra efforts from the lecturer in terms of the initial preparation of the lecture material, or in editing and annotating after the lecture to make the material suitable for the students. To review the material students then require access to the proprietary software. This paper describes a system for the lightweight capture of lecture presentations, based on the use of a low-cost large interactive display surface, together with standard Microsoft PowerPoint™ presentation software. The captured version of the presentation includes the original lecture slides, graphical annotations made by the lecturer during the lecture, and the audio recording of the lecture; all saved as a PowerPoint file. In addition, the system adds some annotations and index slides to allow quick and easy access to different segments of the presentation. Presentations can be replayed in part or in full as required, preserving all of the content of the live lecture

Traffic Safety Basic Facts 2012 : Main figures

The CARE database brings together the disaggregate details of road accidents and casualties across Europe, by combining the national accident databases that are maintained by all EU member states. Access to the CARE database is restricted, however, so it is important that a comprehensive range of publications based on these data be accessible to the general public. This process was begun in the SafetyNet project that was carried out between 2004 and 2008, and the concept of the Basic Fact Sheet (BFS) Basic Fact Sheets and Annual Statistical Report (ASR) was developed. By 2008, twelve Fact Sheets were being prepared annually by researchers at five institutes. This Fact Sheet presents an overview highlighting the main facts for Main figures. Wherever possible, measures of risk are calculated by relating the number of fatalities from CARE to exposure data available from other sources. Most Fact Sheets examined trends over the period 2001-2010, with more detailed analyses of data from 2010

This report represents the University of Waikato Usability Laboratory’s (Usability Laboratory) analysis of the Large Interactive Display Screen (LIDS) technologies as developed by the LIDS Research Group. The Usability Laboratory conducted three exploratory-type studies of the LIDS technology over January and February 2002. The studies each focused on individual elements of the LIDS technology, while at the same time contributing to the general understanding and knowledge of the technology
