User-centered design and evaluation of an interactive visual-haptic-auditory interface : a user study on assembly

Utilizing user-centred system design and evaluation method has become an increasingly important tool to foster better usability in the field of virtual environments (VEs). In recent years, although it is still the norm that designers and developers are concerning the technological advancement and striving for designing impressive multimodal multisensory interfaces, more and more awareness are aroused among the development team that in order to produce usable and useful interfaces, it is essential to have users in mind during design and validate a new design from users' perspective. In this paper, we describe a user study carried out to validate a newly developed haptically enabled virtual training system. By taking consideration of the complexity of individual differences on human performance, adoption and acceptance of haptic and audio-visual I/O devices, we address how well users learn, perform, adapt to and perceive object assembly training. We also explore user experience and interaction with the system, and discuss how multisensory feedback affects user performance, perception and acceptance. At last, we discuss how to better design VEs that enhance users perception, their interaction and motor activity.

A systematic scoping investigation of cross-cultural visual communication design

This research project provides a systematic and strcutured investigation into the issues associated with the emergent field of cross-cultural visual communication design. The results of the scoping research and the international cross-cultural design project offer clear guidance for designers through all stages of the communication process. 

Place branding and cross-cultural visual communication : how do the theories and practices of place branding inform our understanding of cross-cultural visual communication design?

In a globalised environment, visual communication designers are now required to understand their audience’s needs, values and unique methods of communication, creating a new focus on the recipient. In a cross-cultural design context, the visual communication also needs to appeal to a broad range of stakeholders and multiple recipients who hold a strong emotional investment in the message being sent. Our understanding of the complexities of designing in this environment can be informed by recent developments in the research of place branding where the focus is on the increased possibility for failure, the strong potential for criticism and the issues associated with a broad range of stakeholders.

The outcomes of this connection are explored further in a case study involving eight countries as diverse as Australia, Brazil, Mexico, South Africa, Turkey, Qatar, United States of America and Zimbabwe. More than 140 student and lecturer participants reviewed a student driven cross-cultural visual communication project that produced over 560 designs. The increased potential for failure and strong, emotional criticism raised questions about the role of images and symbols in cross-cultural visual communication. The impact these have on the reception of the design, challenge our views on the use of stereotypical imagery. This paper will discuss the movement towards designing visual images that are generic and lacking in cultural representation presenting the view that stereotypical imagery is important to the recipient who relies on these cultural references to effectively read the message.

Visual effects in great bowerbird sexual displays and their implications for signal design

It is often assumed that the primary purpose of a male's sexual display is to provide information about quality, or to strongly stimulate prospective mates, but other functions of courtship displays have been relatively neglected. Male great bowerbirds (Ptilonorhynchus nuchalis) construct bowers that exploit the female's predictable field of view (FOV) during courtship displays by creating forced perspective illusions, and the quality of illusion is a good predictor of mating success. Here, we present and discuss two additional components of male courtship displays that use the female's predetermined viewpoint: (i) the rapid and diverse flashing of coloured objects within her FOV and (ii) chromatic adaptation of the female's eyes that alters her perception of the colour of the displayed objects. Neither is directly related to mating success, but both are likely to increase signal efficacy, and may also be associated with attracting and holding the female's attention. Signal efficacy is constrained by trade-offs between the signal components; there are both positive and negative interactions within multicomponent signals. Important signal components may have a threshold effect on fitness rather than the often assumed linear relationship.

Visual communication design as a form of public pedagogy

This paper identifies visual communication design as a form of public pedagogy. Communication design practices aim to achieve the successful transmission of a message to a recipient in a visual mode. Understanding the theories and practices of visual communication design can assist in enhancing the reception of the communication, as these practices become a tool to increase the effectiveness of learning in a public space. To demonstrate this, I will use the example of museums as an informal place of public learning, and argue design, and in particular visual communication design strategies, are extremely important in the creation of successful learning. If participants are not engaged or entertained, their capacity for learning will diminish. Engagement depends on the representation of the information and the successful interpretation of that information by the visitor. Further, this paper will emphasize the vital role communication design plays in all forms of public pedagogy, not just within the museum context. However, non-designers create many public learning environments and although this paper argues the benefits of communication design to increasing the effectiveness of learning, it recognizes the narrow opportunities of applying this knowledge.

Diretrizes para análise e desenvolvimento de identidade visual: contribuições para o design ergonômico

Currently, too much visual information present in all media is form vehemently, for example, in print media and interfaces used for publicity in conjunction with informational design. This visual information has great influence in the lives of human beings, since the vision of these individuals is the sense most used. Studies on visual identity have not explored this issue in a satisfactory manner, favoring thus the subject of this little development projects in the area. Note the need for analyzes to enable implementation principles of projective, making them accessible to the understanding of most individuals. This study aimed to propose an evaluation of visual identities, which were analyzed by means of visual concepts of usability, design methodologies and Gestalt. We contacted design firms specializing in visual identity projects, places where interviews were conducted to collect the marks allowed for analysis. The results point to a frequent demand the employment of visual usability principles, design methodologies and design in Gestalt visual identities.

A percepção visual visando a continuação gráfica na repetição modular do design de superfície

This article narrates from experiences in the classroom, the use of visual perception in the search for the solution of a basic problem of modular repetition, embodied by the lack of continuity in the elements that shape the design surface. Although Wong (1998) approach emphasizes the intuitive and intellectual approach as different parameters for building visual compositions, we list both as participants in the same focus, where the solution starts from the sensory stimulation.

An fMRI-study of locally oriented perception in autism: altered early visual processing of the block design test

Autism has been associated with enhanced local processing on visual tasks. Originally, this was based on findings that individuals with autism exhibited peak performance on the block design test (BDT) from the Wechsler Intelligence Scales. In autism, the neurofunctional correlates of local bias on this test have not yet been established, although there is evidence of alterations in the early visual cortex. Functional MRI was used to analyze hemodynamic responses in the striate and extrastriate visual cortex during BDT performance and a color counting control task in subjects with autism compared to healthy controls. In autism, BDT processing was accompanied by low blood oxygenation level-dependent signal changes in the right ventral quadrant of V2. Findings indicate that, in autism, locally oriented processing of the BDT is associated with altered responses of angle and grating-selective neurons, that contribute to shape representation, figure-ground, and gestalt organization. The findings favor a low-level explanation of BDT performance in autism.
