Abstract
A smart house is usually described as an interactive house where information and communications technology is used to support the daily tasks of its inhabitants. One of the important components of a family house context is the food storeroom or pantry. In a fully smart house, the pantry should also be supported by information technologies, as it happens with the others components of the house. By other means, in a fully smart house, the pantry should be smart too. In this paper we present an UML specification for a smart pantry management system. We also discuss all the process that was followed to identify the system requirements, to build the systems models and to create the system prototype. As final remarks we present some guidelines for the future development of a complete smart pantry system. © 2008 IADIS.

MANAGEMENT AND CONTROL OF PRODUCTION AND LOGISTICS, VOL 1 AND 2

Abstract
A major transport company working in a urban environment, in Portugal, has been developing an automatic vehicle location (AVL) system, based on a telemetric system to assist the optimisation of vehicle use, time-tabling and scheduling. The data is used in real time and stored on disk for later statistical analysis. Several factors can corrupt data during acquisition and transmission, and make it impossible to automatically extract useful information. A pre-processing stage is needed to extract inconsistent data. The paper describes a strategy, based on simulation, to pre-process the data in order to analyse data consistency and classify the messages as correct or incorrect. Copyright (C) 1998 IFAC.

Abstract
It is well known, widely accepted, scientifically proved and published by major governmental and non-governmental organizations worldwide (e.g. WHO - World Health Organization), that nutritional misbehaviour in so called developed countries, is a major cause of diseases, morbidity and death. The phenomenon is mainly felt in aged populations, but a significant increase has also been detected more recently in young populations. This paper presents a proposal to tackle serious social and behavioural problems related to aging and nutrition. NutriMe is presented as a nutritional monitoring and advising system to help individuals to monitor and correct their behaviours. We also propose NutriMe as the main component for a public national observatory on nutritional profiles for public health analysis purposes.

USABILITY of 3D CONTROLLERS in SECOND LIFE

PROCEEDINGS OF THE 3RD INTERNATIONAL CONFERENCE ON SOFTWARE DEVELOPMENT FOR ENHANCING ACCESSIBILITY AND FIGHTING INFO-EXCLUSION (DSAI 2010)

Abstract
The Second Life platform unites various technologies: 3D virtual environments, virtual reality, Internet connection between participants and the possibility of customization of the three-dimensional content. It is a virtual collaborative environment that allows users to explore digital worlds and interact with others in real time. Increasingly, new peripherals to interact with virtual environments are emerging in the market, and good examples of this are 3Dconnexion's 3D controllers. These are designed to be easy to use, allowing users to zoom, move around in space and rotate 3D objects with a simple hand tap on the device. With this project we wanted to identify usability problems among 3Dconnexion's devices in Second Life 3D virtual environment. We created a usability test and implemented it. With its data we identified usability features of these 3D controllers.

Planning of a usability test for 3D controllers in Second Life / OpenSimulator virtual worlds

Abstract
3D interface devices are being announced as rendering virtual world navigation easier. We have prepared a usability testing framework for two such devices, SpaceNavigator and SpacePilot PRO, manufactured by 3Dconnexion. The paper summarizes the underlying concepts of usability testing and links them to the requirements of a virtual world 3D interface context. We detail the metrics to be employed and the reasoning behind their selection, and the planning which yielded the actual framework to be used for conducting the 3D interface usability tests in the Second Life virtual world. © 2011 IEEE.

Usability test of 3Dconnexion 3D mice versus keyboard plus mouse in Second Life undertaken by people with motor disabilities due to medullary lesions

Abstract
The use of keyboard and mouse combinations to navigate 3D environments of virtual worlds requires the coordination of both hands in order for the 2D degrees of motion of the mice to transform into the variety of motions available in a 3D space. Such coordination may pose a challenge to people with motor disabilities. 3D controllers known as "3D mice" are presented by manufacturers as significant interface alternatives. To establish the feasibility of such claims, we have conducted a usability test of two 3D mice marketed by 3Dconnexion, in parallel with a keyboard+mouse test. The 10 participants had motor disabilities due to medullary lesions on vertebrae C5-D11, and performed 13 different tasks in the Second Life virtual world: 5 participants used 3D mice, 5 used keyboard+mouse. We have concluded that 2-3 of the 5 most challenging tasks in the keyboard+mouse combination become less challenging using 3D mice. Participants' feedback was more positive regarding 3D mice, but with significant differences between mice. Contrary to our initial expectations, the least stable mouse, Space Navigator, originated the best feedback. (C) 2012 The Authors. Published by Elsevier B.V.
