2nd Cycle Studies - Mestrado

Recommended Prerequisites

As this course addresses the application of competencies in various areas – programming, data analysis, communication protocols, and others – it has as prerequisite a transversal use of the knowledge acquired in a typical bachelors degree in informatics engineering or computer science.

Teaching Methods

Teaching methodologies and resources include theoretical classes and lab classes. The course also comprises:

- development of a short project along the semester

- slides of the theoretical classes

- demonstration systems (some of them developed by the students in the previous years

- smartphones an specific hardware

The evaluation comprises (scoring detailed ahead):

- Exam

- Project with the following items being evaluated: proposal, follow up, presentation at a workshop and technical documentation.

Learning Outcomes

Ubiquitous computing realises the vision of Mark Weiser – ―a physical world richly and invisibly interwoven with sensors, actuators, displays’ and computational elements, embedded seamlessly in the everyday objects of our lives and connected through a continuous network‖.

Ubiquitous computing is an area that integrates various competences – programming, artificial intelligence, information systems, networking, and others.

In this course the students acquire the knowledge and competences for conception and development of ubiquitous systems and their integration in the existing information systems. Particular emphasis is devoted to the study of approaches for positioning, place representation, context awareness, privacy and security management and evaluation of ubiquitous systems.

Work Placement(s)
