Ainda hoje, as técnicas existentes para a manipulação de slides se apresentam restritas. Em geral, ocorre a interrupção frequente da apresentação para que o apresentador se desloque ao computador para o controle dos slides. Este livro apresenta a construção de um sistema de baixo custo que possibilita o controle de apresentações de slides em projetores multimídia por meio da visão computacional e processamento digital de imagens. O aplicativo constitui basicamente de duas etapas: uma de calibração em que a região da área de projeção que o usuário pode interagir é detectada e outra que diz respeito à apresentação. O controle ocorre a partir de um sistema de rastreamento que gera ações na apresentação a partir da posição da mão do apresentador. Uma webcam é utilizada como um sensor para a captura, em tempo real, de imagens da apresentação. Estas imagens passam por algoritmos e técnicas de visão computacional e processamento digital de imagens para que seja possível detectar alterações na cena. Quando alterações são detectadas, comandos são executados sobre os slides.
This book constitutes the proceedings of the First International Conference on Information and Communication Technology for Development for Africa, ICT4DA 2017, held in Bahir Dar, Ethiopia, in September 2017. The 31 revised full papers presented were carefully reviewed and selected from 72 submissions. The papers address the impact of ICT in fostering economic development in Africa. In detail they cover the following topics: e-services, natural language processing, intelligent systems, mobile and wireless communication, privacy and security.

Cyber-physical systems (CPSs) combine cyber capabilities, such as computation or communication, with physical capabilities, such as motion or other physical processes. Cars, aircraft, and robots are prime examples, because they move physically in space in a way that is determined by discrete computerized control algorithms. Designing these algorithms is challenging due to their tight coupling with physical behavior, while it is vital that these algorithms be correct because we rely on them for safety-critical tasks. This textbook teaches undergraduate students the core principles behind CPSs. It shows them how to develop models and controls; identify safety specifications and critical properties; reason rigorously about CPS models; leverage multi-dynamical systems compositionality to tame CPS complexity; identify required control constraints; verify CPS models of appropriate scale in logic; and develop an intuition for operational effects. The book is supported with homework exercises, lecture videos, and slides.
This book is concerned with computing in materio: that is, unconventional computing performed by directly harnessing the physical properties of materials. It offers an overview of the field, covering four main areas of interest: theory, practice, applications and implications. Each chapter synthesizes current understanding by deliberately bringing together researchers across a collection of related research projects. The book is useful for graduate students, researchers in the field, and the general scientific reader who is interested in inherently interdisciplinary research at the intersections of computer science, biology, chemistry, physics, engineering and mathematics.
