This paper presents the Hefestos Smart Wheelchair with sensing capability, designed to provide ubiquitous accessibility. The project aims at supporting accessibility for wheelchair users in various situations of their everyday life. Offering context awareness, user profiles, and trails We also present the evaluation of the prototype academic experiment. This assessment used which is under development at University of the Valley (Unisinos). The prototype was operated by users.

“…The environment itself is equipped with low cost passive RFID tags. For those cases in which information sharing is desired, security can be improved by the use of available protocols for two-way authentication [6] that can be plugged into our systembut are outside of the purview of this document.Context aware frameworks [7], [8], [9], [10] would serve to enhance the robustness of the solution proposed in this paper.

The current ubiquitous presence of RFID tech nology opens up possibilities for new applications. The RFID enabled indoor pervasive environment is the area of interest for our study. We explore the system requirements for an RFID enabled pervasive system and develop a middle ware called GuardianAngel to support a monitoring and guidance system for use in an assisted living environment. This paper describes a prototype of such a system, using real RFID devices in a proof of-concept to evaluate feasibility and emulated RFID devices to evaluate scalability. Our study illustrates the feasibility of such a system, demonstrating greater than 99% accuracy in situ with a confined testbed, and with above 93% accuracy estimated when emulated in a larger environment.

Resumo: Observa-se hoje um crescimento do número de dispositivos móveis disponíveis no mercado. Esses aparelhos estão cada vez mais ao alcance da população, seja pelo valor, cada vez mais acessível, seja pela facilidade de uso. Apesar disso, os sistemas operacionais desses dispositivos não estão preparados para atender pessoas com determinados tipos de deficiência, principalmente quando se trata de problemas visuais. O presente trabalho tem por objetivo propor um modelo de acessibilidade para dispositivos móveis, orientado ao suporte de pessoas que possuam algum nível de deficiência visual. Também são descritos cenários onde o modelo pode ser aplicado e o protótipo que foi desenvolvido para validá-los. Por fim, são apresentados os resultados obtidos após a execução dos cenários propostos. Palavras IntroduçãoHá aproximadamente vinte anos, Mark Weiser introduziu o conceito de computação ubíqua [1], prevendo um mundo onde dispositivos computacionais estariam presentes em objetos, ambientes e nos próprios seres humanos, interagindo naturalmente com os usuários sem que fossem percebidos. Dez anos após, Satyanarayanan reforçou o conceito através de um artigo considerado clássico [2].Nos últimos anos a evolução da tecnologia vem viabilizando a computação ubíqua, pois os equipamentos móveis estão cada vez menores e mais poderosos. Além disso, o advento das tecnologias de comunicação sem fio permitiu aos equipamentos acessarem serviços em qualquer lugar e a qualquer momento. Adicionalmente, a
