Avaliação de interface de um aplicativo para uso em telefone celular e voltado para a terceira idade BIBAFull-Text 1-10
  Artur Martins Mol; Lucila Ishitani
This paper presents the results of an interface evaluation of Termoquiz, an educational game for seniors, developed for mobile phone. This study aimed to evaluate whether the usability metrics recommended for application interface for desktops or notebooks, considering the seniors, are also valid for cell phones. The choice of cell phones was based on research results that indicate that elderly people have less aversion against cell phones than they have against computers [2]. The results point to the need of interface adjustments to improve older users experience.

  Patricia Tavares; Luiz Agner; Simone Bacellar Leal Ferreira
This paper presents the observational method of scenario and task based interviews to evaluate software usability. This is a flex form of field usability tests, which was adapted to Brazilian Institute of Geography and Statistics corporate context. This technique was created to be implemented with the users using PDAs (Personal Digital Assistants), mobile devices for statistical surveys. A software application was developed to support the digital questionnaire of the Continuous National Household Sample Survey and its usability was evaluated.
Avaliação do uso da manas como ferramenta epistêmica no projeto de sistemas colaborativos BIBAFull-Text 21-30
  Raquel Oliveira Prates; Rodrigo Ferreira da Silva
The Semiotic Engineering theory of Human-Computer Interaction defines epistemic tools as those that allow the designer to reflect about the problem space and available solutions when designing an interactive system. Thus, Semiotic Engineering points out to the importance of offering designers such tools. In this context, Manas was proposed as an epistemic tool that can support designers' of collaborative systems in identifying and reflecting (at design time) about potential social impacts the system may have on a group of users. In this paper we present the first evaluation of Manas' use at design time. The results of this evaluation illustrate how Manas can support designers reflection about the system's social impact on user, and its contribution. It also indicates the costs involved in learning and using the proposed model.
Bringing users of a digital divide context to website evaluation using WELFIT BIBAFull-Text 31-40
  Vagner Figuerêdo de Santana; Maria Cecília Calani Baranauskas
The will of users to be part of a website evaluation depends on a number of variables (emotional state, context of use, etc). Especially remote evaluation tools must care about the invitation mechanism used. This work presents results of a participatory practice that observed how a diverse group of users deals with an invitation of a remote evaluation tool. WELFIT (Web Event Logger and Flow Identification Tool) is a remote evaluation tool that records client-side data during informal use of a website. This work aimed at verifying how the participants interact with the component of the tool added to a user interface of a well known application, the Vila na Rede, an Inclusive Social Network website. The results corroborate assumptions made during the requirements elicitation for the tool and also bring characteristics that would increase users willing to participate in this kind of evaluation. These characteristics would help evaluation tool developers to bring more users to remote studies involving client-side logging.
Considerações sobre Aplicação do Método de Avaliação de Comunicabilidade ao domínio educacional BIBAFull-Text 41-50
  Erica R. de Oliveira; Raquel O. Prates; Gisleide A. M. Werneck
The increasing use of technology in the classroom brings new challenges to the design and evaluation of educational systems and their interfaces. Among these challenges, there is a need to assess how much the system supports learning. In this work, we investigated the applicability of the Communicability Evaluation Method (CEM) in learning support systems. This method is proposed by the Semiotic Engineering theory and involves the participation of users. By applying CEM to the evaluation of educational systems, we have identified specific considerations that should be taken into account when applying this method to the educational domain. By doing so it was possible to identify not only interface problems, but also problems related to the content or students' learning.
Conversas online: a synchronous communication tool integrated to inclusive social networks BIBAFull-Text 51-60
  Leonelo D. A. Almeida; Elaine C. S. Hayashi; Júlio C. Reis; M. Cecília Martins; M. Cecília C. Baranauskas
Computer-Mediated Communication tools as Instant Messaging are currently built for those who are already accustomed to the digital technology. When considering contexts of vast socio-economical diversity found in developing countries (e.g. China, India and Brazil), this type of tools may not be adequate. Focusing on average users when developing communication tools usually results in non inclusive solutions. This paper first describes our attempt to change this scenario by eliciting ordinary people's requirements in the context of the Brazilian population for the development of a synchronous communication tool integrated to an Inclusive Social Network. Following we present our prototype and practices with a target audience. As results, we point out considerations that may guide designers in developing Instant Messaging tools that are supposed to be used in contexts of vast diversity of user profile.
Estendendo a linguagem MoLIC para o projeto conjunto de interação e interface BIBAFull-Text 61-70
  Ugo Braga Sangiorgi; Simone Diniz Junqueira Barbosa
The storyboarding technique is widely adopted for low fidelity prototyping, providing a global view of the sequence of interfaces of a system, together with scenarios. However, the product of such a technique is by definition disposable, partly because they do not have a structure representation, hindering its usage in an evolving development process. In this paper, we argue that interaction design may benefit from an interaction model extended with user interface sketches used in storyboards, thus promoting a more comprehensive discussion about design decisions throughout a project. We have developed an extension to the MoLIC language and a tool to support the construction of diagrams with user interface sketches, and conducted an exploratory study to evaluate it.
Estratégias para comunicar qualidade na Wikipedia BIBAFull-Text 71-80
  Raquel Lara dos Santos; Raquel Oliveira Prates
In open and collaborative encyclopedias like Wikipedia, communication to users about the quality of its articles is essential to increase the reliability of the information disclosed. In this article, we identify and evaluate the strategies provided by Wikipedia, to associate quality to an article. To do so the Semiotic Inspection Method is applied scientifically. The result was the identification of nine different strategies. The evaluation has also pointed out potential problems in how the strategies are conveyed to users.
FAVIHC -- framework de avaliação da interação Humano Computador, estudo de caso na televisão digital BIBAFull-Text 81-90
  Albert Schilling Gomes; Elizabeth S. Furtado
From the moment the specification of a system or product to its delivery, various types of evaluations can be conducted, involving aspects such as functionality, usability, etc. This worked a framework was developed to promote the evaluation of interactive systems from the viewpoint of four perspectives: Needs, Requirements and Design Solutions, Products and Systems. The framework is based on the quality model proposed in ISO/IEC 9126 which suggests that the evaluation of the characteristics of a software is made according to three types of quality: internal quality, external quality and quality in use. The proposed framework was applied in a case study of interactive Digital TV (TVDi).
Interação com conteúdo complementar para apoio ao entendimento de programas televisivos BIBAFull-Text 91-100
  Kamila R. H. Rodrigues; Erick L. Melo; Patricia I. Nakagawa; Cesar A. C. Teixeira
For many people television is still the main form of entertainment. It is a kind of entertainment which is becoming less passive, to the extent that new technology is being applied to the area, especially with digital TV and viewers are changing the way they watch TV. In this new scenario, a new TV, digital, interactive, lets the viewers shop, take part in surveys, send emails, among other facilities, through the remote control. These possibilities bring new challenges, including the provision of interfaces that enable users to enjoy the offered features. The digital interactive TV must minimize barriers and promote accessibility to different types of audiences, including the users who have some trouble to understand the broadcast content. In this paper, through a pilot case study, it was possible to analyze a group of users and the existence of difficulties to understand the transmitted content. These difficulties are presented in different levels and depend on several factors, including cultural and educational factors. Suggestions for this public accessibility may be provided using additional content to television programs. The use of such content lets users to take advantage of the programs as they become more enjoyable and profitable.
Making interactive systems more flexible: an approach based on users' participation and norms BIBAFull-Text 101-110
  Vânia Paula de Almeida Neris; M. Cecília C. Baranauskas
One approach for suiting the diverse and mutable interaction requirements is to tailor interfaces according to the users' preferences or needs. Although literature regarding tailoring presents results with diverse foci, there has been a lack of works considering methods and techniques to support designers in their practice. This paper presents a practical approach to elicit and formalize the tailorable behavior making interactive systems more flexible. The elicitation of the different possible interfaces is performed with users' participation and the tailorable behavior is formalized with a norm-based structure. A case study is described as well as the evaluation with final users.
Meta-communication in inclusive scenarios: issues and alternatives BIBAFull-Text 111-120
  Elaine C. S. Hayashi; M. Cecília C. Baranauskas
Considering the growing need of providing government services through the Internet, it is fundamental to make these systems accessible and inclusive, in order to reach the majority of citizens. In this paper we present a proposal of a meta-communication mechanism to support users in inclusive social networks and the validation of a prototype tool by a community of users in a Brazilian city. Furthermore, based on lessons learned from the activity reported here and from previous investigations, we describe the Design Rationale for this mechanism in an attempt to inform designers of inclusive systems about suitable alternatives to issues that arise during the development of the application.
Patterns for the design of musical interaction with everyday mobile devices BIBAFull-Text 121-128
  Luciano V. Flores; Marcelo S. Pimenta; Eduardo R. Miranda; Eduardo A. A. Radanovitsck; Damián Keller
The growing popularity of mobile devices gave birth to a still emergent research field, called Mobile Music (music with mobile devices). Our particular research investigates such repurposing of ordinary mobile devices for use in musical activities. In this paper we propose the use of patterns in the design of musical interaction with these devices. We introduce the musical interaction patterns that came out of our investigation so far, and describe the exploratory prototypes which served as inspiration and, at the same time, as testbed for these proposed interaction patterns.

  Mauricio Cirelli; Plínio Thomaz Aquino; Lucia Vilela Leite Filgueiras
This paper presents the usage of the Personas technique in order to help interaction projects for mobile web sites. Based on researches about Brazilian cell phone market, we have defined archetypical mobile devices using the persona technique. The resulting group of fictitious models intends to help designers abstract the large number of possible devices. We review W3C (World Wide Web Consortium) mobile best practices as an example of usage of the mobile device personas in design.
Reconstruindo o diálogo em sistemas de ajuda BIBAFull-Text 139-148
  Mauro F. Santos; Milene Selbach Silveira
Despite the advances of computer systems, there are still few alternatives of help systems. New paradigms are needed because the possibilities of help systems are still poorly explored both by end users and by the designers. This paper explores research on help systems, based on a new paradigm: the dialogue between the user and the system. From this research emerged an approach to reduce their communication gaps and transform that communication into something closer to a natural dialogue.
Softwares sociais: uma visão orientada a valores BIBAFull-Text 149-158
  Roberto Pereira; M. Cecília C. Baranauskas; Sergio Roberto P. da Silva
Social software have been triggering transformations that are changing the way people relate, use and are affected by technology. The opportunities and challenges brought by this kind of interactive systems require traditional methods of design and evaluation to be rethought and new concepts, such as human and technical values, be considered in computing systems. This paper presents a discussion on the concept of social software and places this kind of system in the context of human and technical values. As main contribution, it presents a set composed of 27 personal, social and technical values identified through an extensive literature review for supporting social software analysis.
Um sistema de interação baseado em gestos manuais tridimensionais para ambientes virtuais BIBAFull-Text 159-168
  Silvia E. Ghirotti; Carlos H. Morimoto
With the steady price reduction of 3D visualization devices such as Head Mounted Displays (HMDs) and more recently 3D TVs, we can now foresee the dissemination of applications that was only possible within very expensive virtual reality environments. However, interaction within virtual 3D environments requires more natural modes than those provided by the ubiquitous mouse and keyboard. In this paper we introduce a novel low cost 3D hand gesture based interaction system. We have developed a real-time stereo computer vision system and a hybrid interface that combines natural and symbolic gestures for navigation and manipulation of 3D objects in virtual environments. Results from a pilot study reveals that the hybrid interface presents great power and flexibility without significant increase in the complexity of the user interaction.
Universal design principles combined with web accessibility guidelines: a case study BIBAFull-Text 169-178
  Leonelo Dell Anhol Almeida; Maria Cecília Calani Baranauskas
Accessibility evaluation processes currently face important issues. One is the difficulty to understand the issues pointed out in accessibility guidelines and the procedure to correct them. Other regards the coverage of the accessibility guidelines in relation to the whole technical and social aspects, and contexts of use. Those deficiencies contribute to the low adherence to recommendations and naive solutions since designers usually are not experts in accessibility. Aiming at contributing to this scenario in clarifying understanding and action towards the development of accessible code we proposed a merging of accessibility guidelines for web content from WCAG 2.0 and accessibility physical recommendations from ISO 9241 to Universal Design principles and guidelines. To evaluate our approach we conducted a case study involving students in computer science and specialists in web accessibility. As results we verified relevant contributions regarding the number and quality of the identified accessibility issues even for the specialists in accessibility.
Validação de um método para identificação de problemas de usabilidade a partir de diagramas UML BIBAFull-Text 179-188
  Tiago Silva da Silva; Milene Selbach Silveira
Aiming to take the usability evaluation of interactive systems to the early stages of the software development process we propose a method to the model-based usability evaluation. In order to cover subjective aspects and evaluate models used in the real world we propose a non-automatic method to be applied on software engineering models: guidelines to model-based usability evaluation. To refine the proposed method, we carried out some experiments combining different evaluation methods and models. After the method definition and refinement, we carried out an experiment to validate our proposal. From the results of this experiment we may say that we reach a set of guidelines to anticipate the usability evaluation using models. The validation process is presented in this paper.

Incremental computation of information landscapes for dynamic web interfaces BIBAFull-Text 205-208
  Vedran Sabol; Kamran Ali Ahmad Syed; Arno Scharl; Markus Muhr; Alexander Hubmann-Haidvogel
This paper presents a technique for the visual analysis of topical shifts in dynamically changing textual archives. Our approach is based on the well-known information landscape metaphor, whereby topical changes are represented by changes in landscape topography. Incremental clustering and multi-dimensional scaling algorithms are periodically applied to a changing document set for generating a series of information landscapes. The resulting landscapes are suitable for dynamic Web interfaces, enabling the user to explore topical relationships and understand topical shifts and trends in changing document repositories.

Qualidade de uso de um sistema de TV digital BIBAFull-Text 221-224
  Danielly B. Guimarães; Elizabeth S. Furtado
A clear definition of quality goals of the business processes of a proposed system and the establishment of responsibilities among stakeholders (professionals, users and organizations), individually and systemically, are basic requirements for the success of this proposal. A framework is proposed to guide those involved to implement practices and ISO Usability and Interactive Digital TV (TVDi). The standards proposed in this framework were obtained from a socio-technical scenarios relating to a digital TV system. An analysis of theoretical and practical experiences on the deployment of digital TV shows there are challenges to apply them caused by attitudes fragmented and where the user does not have the central role.

O uso de descrições narrativas para avaliar significados em interfaces de usuário BIBAFull-Text 265-266
  Macilon Araújo Costa Neto; Jair Cavalcanti Leite
Production and interpretation of meanings are fundamental in HCI. To the semiotic engineering theory, the designer needs to construct a user interface to communicate his/her intended solution to the user. In order to appropriately use a computing system, the user should interpret the designer's intended meanings. In our project, we investigate the use of scripts to express the user interface meanings in natural language as an epistemic tool to analyze differences in stakeholders' interpretations. As a first step, we define a dictionary of interactive signs that could be use to generate user interface scripts.
