This paper introduces a new AAL architecture intended to simplify and enhance the end user interaction with the technology. The proposed concept makes state-of-the-art task model technology available and accessible to all types of users. The concept relies on the integration of both ANSI/CEA-2018 Task Model Description (CE TASK 1.0) and ISO/IEC 24752 Universal Remote Console Framework standards. Additionally, a proof-of-concept implementation has been carried out which assist people in performing blood pressure measurements. Finally, a validation involving 8 elderly persons suffering from Alzheimer's disease has been carried out, obtaining encouraging results. © 2010 IEEE. Source

One of the challenges that Ambient Intelligent (AmI) faces is the provision of a usable interaction concept to its users, especially for those with less technical background. In this paper, we describe a new approach to integrate interactive services provided by an AmI environment with the television set, which is one of the most used interaction client in the home environment. An implementation of this approach has been carried out as a multimodal/ multipurpose natural human computer interface for elderly people, by creating adapted graphical user interfaces and navigation menus together with multimodal interaction (simplified TV remote control and voice interaction). In addition, this user interface can also be suited to other user groups. We have tested a prototype that adapts the videoconference and the information service with a group of 83 users. The results from the user tests show that the group found the prototype to be both satisfactory and efficient to use. © 2011 IEEE. Source

Our study area is located in northwestern Argentina. It is a semiarid valley in which developed agricultural pre-Columbian settlements were located. The objectives of our research were to establish the geomorphological characteristics of the area, its relative chronological development, and the relationships between geomorphological development and pre-Columbian settlements. Pre-Quaternary lithologies are represented by a metamorphic basement that is commonly exposed on slopes and belongs to the Precambrian and Cambrian periods. Tertiary sediments from several formations are exposed over an extensive surface forming cuesta relief landforms. Quaternary landscape units were classified according to their genesis into structural-denudational landforms (denudational slopes and structural scarps), denudational landforms (covered glacis), fluvio-alluvial landforms (alluvial fans, fluvial fans, and fluvial terraces) and aeolian forms (stabilized dunes). Archaeological sites belonging to the Formative (500 BC-AD 1000) and Regional Development (AD 1000-1500) periods were identified. The main archaeological sites are located on the surfaces of debris-flow deposits and some covered glacis. They are characterized by the presence of residential units together with agricultural structures (terraces and irrigation channels). The earlier settlements (Formative period) are restricted to alluvial fan landforms (debris-flow deposits), where present hydrological supply is lower than in the rest of the study area. Later settlements (Regional Development period) are juxtaposed with earlier settlements in the south of the area, where present hydrological supply is higher owing to larger river catchments and moistureladen winds from the SE. © The Geological Society of London 2011.

The use of user models can be very valuable when trying to develop accessible and ergonomic products and services taking into account users’ specific needs and preferences. Simulation of user–product interaction using user models may reveal accessibility issues at the early stages of design and development, and this results to a significant reduction in costs and development time. Moreover, user models can be used in adaptive interfaces enabling the personalised customisation of user interfaces that enhances the accessibility and usability of products and services. This paper presents the efforts of the Virtual User Modelling and Simulation Standardisation ‘VUMS’ cluster of projects towards the development of an interoperable user model, able to describe both able-bodied and people with various kinds of disabilities. The VUMS cluster is consisted by the VERITAS, MyUI, GUIDE, and VICON FP7 European projects, all involved in user modelling from different perspectives. The main goal of the VUMS cluster was the development of a unified user model that could be used by all the participant projects and that could be the basis of a new user model standard. Currently, within the VUMS cluster, a common user model has been defined and converters that enable the transformation from each project’s specific user model to the VUMS user model and vice versa have been developed enabling, thus, the exchange of user models between the projects. © 2014, Springer-Verlag Berlin Heidelberg.

A vast number of people with disabilities are supported by assistive technologies (AT). Often, AT solutions do not directly fit the specific requirements of a user, making costly adaptations necessary. Assistive Technology Rapid Integration & Construction Set (AsTeRICS) aims to change this situation by employing rapid prototyping technologies in AT. A construction set of building blocks to create flexible prototypes for each individual user is provided. This set is configured by a visual modelling software application which allows to connect all building blocks as needed, tailoring the prototype to the user's abilities and needs. Building blocks include sensors (which in this context includes not only stand-alone sensors such as simple switch inputs but also vision systems, brain computer interfaces, and many more), data processing elements (mathematical and flow control), and actuators (such as mouse/keyboard replacement, smart environments, and mobile phone access). As central part of AsTeRICS, a runtime environment has been developed, handling all signal processing and data exchange operations needed for the interaction of the building blocks.
