Scanning is one of the most popular text input methods for people with severe movement restrictions due to diverse kinds of disabilities. It is frequently used to input messages into communication systems, such as text-tovoice translators in order to maintain conversations. Nevertheless, the rate of text production usually obtained is very slow. For this(More)
Biofeedback from physical rehabilitation exercises has proved to lead to faster recovery, better outcomes, and increased patient motivation. In addition, it allows the physical rehabilitation processes carried out at the clinic to be complemented with exercises performed at home. However, currently existing approaches rely mostly on audio and visual(More)
Prediction is one of the techniques that has been applied to Augmentative and Alternative Communication to help people enhance the quality and quantity of the composed text in a time unit. Most of the literature has focused on word prediction methods that may easily be applied to non-inflected languages. However, for inflected languages, other approaches(More)
Ambient Supported Living systems for people with physical, sensory or cognitive restrictions have to guarantee that the environment is safe, fault tolerant and universally accessible. In addition it is necessary to overcome technological challenges, common to ubiquitous computing, such as the design of a middleware layer that ensures the interoperability of(More)
This paper presents the design and development of the Robochair robotic wheelchair and its performance within the AmbienNet project. Robochair is an open robotic platform intended to assist challenged users with their daily driving tasks. It uses and extents the Player robotics framework providing uniform access to either robotics hardware and user(More)
In this paper, we describe a context server application for mobile computing. Its main objective is to assist developers to exploit context-aware features in their applications. This approach uses the extraction of new context information using a combination of sensors and proposes a sensing abstraction layer to avoid having to deal with specific hardware.
Ubiquitous Computing has proved to be an excellent way of providing technological support for the daily life of people within its range. Ambient Assisted Living (AAL), which is largely based on Ubiquitous Computing, aims at tutoring and supervising elderly people and users with physical, sensory or cognitive disabilities in the performance of routine(More)
The comparison of actions in the physical world with actions on interactive devices reveals a remarkable difference. In daily life we easily perform several tasks in parallel, e.g. when drinking coffee while reading this text, drinking may be in the background or periphery of the attention. Contrarily, we almost always have to focus our attention on each(More)
