From the Publisher: 
The accessible presentation of this book gives both a general view of the entire computer vision enterprise and also offers sufficient detail to be able to build useful applications. Users learn techniques that have proven to be useful by first-hand experience and a wide range of mathematical methods. A CD-ROM with every copy of the text contains source code for programming practice, color images, and illustrative movies. Comprehensive and up-to-date, this book includes essential topics that either reflect practical significance or are of theoretical importance. Topics are discussed in substantial and increasing depth. Application surveys describe numerous important application areas such as image based rendering and digital libraries. Many important algorithms broken down and illustrated in pseudo code. Appropriate for use by engineers as a comprehensive reference to the computer vision enterprise.

The Achievement Motive

3. The purpose of the Bill is to give effect to proposals published in May 2003 to deal with those suspected of terrorist-related offences committed before the date of the Belfast Agreement (10 April 1998) in connection with the affairs of Northern Ireland, who have not yet been tried or convicted because they have been 'on the run'. The Bill also makes comparable provision for those who might be charged in the future with terrorism-related offences committed before that date, and for those who have already been convicted of such offences.

Mobile devices are becoming the mass IT platform of the future, reaching people that have never accessed the digital world. Aiming at digitally including visually impaired people also, it is necessary to address solutions that overcome natural barriers originating from the touch screen feature? a growing market trend. This concern has already triggered a number of researches and also some commercial solutions. However, a survey conducted to identify user requirements with blind and partially-sighted people evidenced that the few solutions available on market and the cutting-edge research are far from the reality for visually impaired people in a developing country scenario. To bridge this gap, this paper defines a set of guidelines that has been applied on the development of an accessible interaction model for mobile devices in the Brazilian context.

Developing an accessible interaction model for touch screen mobile devices: preliminary results

Big tech-players have been successful in pushing the chatbots forward. Investments in the technology are growing fast, as well as the number of users and applications available. Instead of driving investments towards a successful diffusion of the technology, user-centred studies are currently chasing the popularity of chatbots. A literature analysis evidences how recent this research topic is, and the predominance of technical challenges rather than understanding users’ perceptions, expectations and contexts of use. Looking for answers to interaction and design questions raised in 2007, when the presence of clever computers in everyday life had been predicted for the year 2020, this paper presents a panorama of the recent literature, revealing gaps and pointing directions for further user-centred research.

Chasing the Chatbots

In 2012, the Brazilian HCI community identified Five Grand Research Challenges in Brazil, for the timespan between 2012 and 2022. In this paper, we discuss 3 issues: (a)what our community has done so far to advance with Challenge 4 - Human Values; (b) what results had effective impacts; and (c) what challenges remain and/or have come up. To do so, we present our perspectives on studies related to the three central axes of this challenge (ethics, privacy and post-mortem digital legacy), along with their potential impacts. Our observations point out that a compartmentalized, narrow mindset might be preventing us from advancing to greater reflections, which could challenge paradigms and articulate the aforementioned axes within the Grand Challenges.

Human Values in HCI: a challenge for the GrandIHC-BR

TV can be regarded as the most far-reaching media in Brazil. Its presence is noticed in 90% of Brazilian homes and it is the main source of information for a major part of the population. The moment of definition and consolidation of the digital TV technology provides us with a unique opportunity for analyzing and discussing this media accessibility. Making sure that TV contents and devices are flexible enough so that people are able to perceive, understand and interact with them is a main asset for its use and an essential requirement for the democratization of information via TV broadcasting. This paper analyzes interactive digital TV accessibility in informal, formal, and technical levels, considering the Brazilian context. In addition, it presents recommendations to design accessible interfaces by referring to the W3C guidelines 2.0 for Web accessibility and specific recommendations for iDTV.

Accessibility and interactive TV: design recommendations for the Brazilian scenario

Despite all technological advances in the energy research field and the ubiquitous presence of technology in all aspects of life, the lack of information is still recognized as a gap to engage people in a pro-environmental behaviour towards energy conservation Consumption feedback is elementary to tackle this paradox, but not enough to trigger a social change It is still necessary to motivate people in order to raise awareness effectively This study associated the feedback provided by smart monitors with a debate tool and a tangible motivational device for building energy awareness collectively in a workplace The analysis of the role of each technology considered assessments and interviews, and also the content of the online discussion, which encompassed more than 170 ideas for changing behaviour for around 100 issues about how the energy has been consumed Results demonstrated that for raising energy awareness, beyond technology, it is also necessary to deal with formal and informal elements, such as institutional practices and individual's motivation These technical, formal, and informal levels shaped our qualitative analysis to identify elements participants considered relevant to learn and to discuss, suggesting their importance to similar initiatives that aims to raise energy awareness in a wider perspective
