WAIS Seminar:Evaluating the Cognitive Side of Information Interaction

Abstract In this talk, I'll focus on the work we've been doing on evaluating the cognitive side of dealing with information resources and increasingly complex user interfaces. While we can build increasingly powerful user interfaces, they often come at the cost of simple design and ease of use. I'll describe two specific studies: 1) work on the ORCHID project focused on measuring mental workload during tasks using fNIRS (a blood-oxygen-based brain scanner), and 2) a evaluation metric for measuring how much people learn during tasks. Together these provide advances towards understanding the cognitive side of information interaction, in working towards building better tools for users.

WAIS Seminar:LinkedTV: Building the Future of Television

Abstract Broadcast video can be augmented with links to information related to the topics in the video and to other related entities. Viewers are sufficiently digitally literate that they can carry out their own searches during or after a broadcast. We investigate what types of information viewers would actually like to see while being engaged in watching a news broadcast. On the base of this we have designed user interfaces for passive and active uses of a second screen to accompany a news broadcast. A next step is to understand the specific types of information users would like to consult and investigate whether these can be automatically generated.

Plan de negocio Gree-Waste

El crecimiento apresurado de la industria tecnológica en los últimos años a nivel mundial, ha generado un nuevo problema socio-ambiental: el manejo y control de los volúmenes de aparatos y componentes electrónicos obsoletos que crecen exponencialmente, específicamente los aparatos que provienen de sistemas de informática, volviéndose en una situación descontrolada y desatendida. Esta problemática empeora cada día por el desconocimiento, la imprudencia, las malas políticas adoptadas por el gobierno y el constante deseo de los consumidores por estar en contacto con los últimos modelos del mercado, reflejándose en un incremento acelerado en las ventas de aparatos electrónicos. Sin embargo, muchos se preguntaran él porque proponemos una idea de negocio caracterizada por lo social y lo ambiental, pues dicha idea viene de la experiencia que se ha tenido durante 7 años en el mercado de tecnología en computación y periféricos, que ha logrado una relación directa con empresas y personas; observando así, las verdaderas preocupaciones de los clientes y a su vez un aumento acelerado en los desechos tecnológicos. De esta manera y siguiendo con el espíritu emprendedor que nos ha caracterizado desde pequeños, hemos llegado a pensar en una idea de negocio interesante y viable, que nos permita incursionar ante competidores importantes y sobresaliendo con una idea innovadora que no se maneja de lleno en dicho sector. Para lograrlo, aprovecharemos los conocimientos y la experiencia que hemos acumulado a través de los años con el contacto directo con los clientes, quienes consideramos son el motor del negocio y llevándonos a concluir con el transcurrir del tiempo, que en Colombia no existe una cultura para desechar los elementos tecnológicos de una manera ecológica y saludable con el medio ambiente. Gracias a la oportunidad latente que muestra el mercado en el sector de reciclaje de desechos tecnológicos, nuestro equipo de trabajo se muestra inquieto ante la oportunidad de negocio encontrada, debido a que en Colombia existen pocas organizaciones que se especialicen en el proceso de reciclaje y reutilización adecuada de dichos desechos. Por esta razón, se confirma la oportunidad para generar un completo plan de negocio que gire en torno al manejo de e-waste y cuidado del medio ambiente, mediante la implementación de productos y servicios especializados para la recolección de dichos desechos electrónicos tanto para los consumidores como para las empresas.

Investigating novel point-select techniques for older people

As the number and proportion of older people worldwide continues to grow, robotic devices can play a role in helping older people continue to live independent and active lives. Graphical user interfaces (GUIs) and interactions that involve pointing to items and selecting them are becoming more common in assistive robots. The authors are currently working on a project investigating techniques to improve point-select interactions for older people. In particular, the project studies how older people respond to expanding and moving targets. The research is ongoing, and this paper describes the methods that will be used in upcoming experiments.

Analysis of the dominant enterprise information assurance mechanisms

The purpose of this study is to analyse current data continuity mechanisms employed by the target group of businesses and to identify any inadequacies in the mechanisms as a whole. The questionnaire responses indicate that 47% of respondents do perceive backup methodologies as important, with a total of 70% of respondents having some backup methodology already in place. Businesses in Moulton Park perceive the loss of data to have a significant effect upon their business’ ability to function. Only 14% of respondents indicated that loss of data on computer systems would not affect their business at all, with 54% of respondents indicating that there would be either a “major effect” (or greater) on their ability to operate. Respondents that have experienced data loss were more likely to have backup methodologies in place (53%) than respondents that had not experienced data loss (18%). Although the number of respondents clearly affected the quality and conclusiveness of the results returned, the level of backup methodologies in place appears to be proportional to the company size. Further investigation is recommended into the subject in order to validate the information gleaned from the small number of respondents.

Monte Carlo methods for matrix computations on the grid

Many scientific and engineering applications involve inverting large matrices or solving systems of linear algebraic equations. Solving these problems with proven algorithms for direct methods can take very long to compute, as they depend on the size of the matrix. The computational complexity of the stochastic Monte Carlo methods depends only on the number of chains and the length of those chains. The computing power needed by inherently parallel Monte Carlo methods can be satisfied very efficiently by distributed computing technologies such as Grid computing. In this paper we show how a load balanced Monte Carlo method for computing the inverse of a dense matrix can be constructed, show how the method can be implemented on the Grid, and demonstrate how efficiently the method scales on multiple processors.

The implementation of a low-cost production-line inspection system

This article describes an application of computers to a consumer-based production engineering environment. Particular consideration is given to the utilisation of low-cost computer systems for the visual inspection of components on a production line in real time. The process of installation is discussed, from identifying the need for artificial vision and justifying the cost, through to choosing a particular system and designing the physical and program structure.

Hyperresolution global land surface modeling: meeting a grand challenge for monitoring Earth's terrestrial water

Monitoring Earth's terrestrial water conditions is critically important to many hydrological applications such as global food production; assessing water resources sustainability; and flood, drought, and climate change prediction. These needs have motivated the development of pilot monitoring and prediction systems for terrestrial hydrologic and vegetative states, but to date only at the rather coarse spatial resolutions (∼10–100 km) over continental to global domains. Adequately addressing critical water cycle science questions and applications requires systems that are implemented globally at much higher resolutions, on the order of 1 km, resolutions referred to as hyperresolution in the context of global land surface models. This opinion paper sets forth the needs and benefits for a system that would monitor and predict the Earth's terrestrial water, energy, and biogeochemical cycles. We discuss six major challenges in developing a system: improved representation of surface‐subsurface interactions due to fine‐scale topography and vegetation; improved representation of land‐atmospheric interactions and resulting spatial information on soil moisture and evapotranspiration; inclusion of water quality as part of the biogeochemical cycle; representation of human impacts from water management; utilizing massively parallel computer systems and recent computational advances in solving hyperresolution models that will have up to 109 unknowns; and developing the required in situ and remote sensing global data sets. We deem the development of a global hyperresolution model for monitoring the terrestrial water, energy, and biogeochemical cycles a “grand challenge” to the community, and we call upon the international hydrologic community and the hydrological science support infrastructure to endorse the effort.
