It’s noticeable that fashion retailing doesn’t always rely on “newness” for a competitive advantage, so the clothing design process should imply subjectivity in the clothing's purpose or preference, as well as in the social behavior of the target market. Therefore, there’s a need to create outfits that highlight the construction and communication of identity over physical product properties.This project uses the Kansei Method to achieve a predictive model for women's gym wear, in order to find outfit tendencies based on the potential user's emotional reactions that will serve as both a model to support the decision-making of the designer through the new product development process, and a...

A virtual building emergency where alarms went off while participants were performing activities was created to study the effect of redundancy on evacuation effectiveness. Three alarms were studied: (i) a regular nonverbal ISO alarm, (ii) a speech‐inserted ISO alarm, and (iii) a technology‐based ISO alarm concept (sound, visual, and haptic information). Evacuation behavior, perceived urgency, and delay time were measured. Results confirmed the effect of redundancy on measurements, and participants complied better with the speech‐inserted and technology‐based alarms, but there were no differences in evacuation effectiveness between them. Participants perceived higher urgency from the tec...

To this aim, usability testing was performed considering a Living Lab approach. Seniors were invited to use the applications in an environment that simulates the one they would use the tested technology during their everyday life. Observation methods, thinking aloud and questionnaires were used to collect data related to the systems' effectiveness and users' satisfaction, namely their expectations, frustrations and difficulties. Evaluations were performed during the initial phases of product development and results were used to improve the applications, considering the development cycle of User-Centered Design methodology.

However, regarding cybersickness, this technology it is not innocuous. We report results concerning cybersickness related with awareness of the secondary effects of VR before doing an experiment. Two groups of participant were found. A group that read the consent form (CF) with attention and a group that did not pay attention to the CF and just signed it. The consent contained information about the experiment and also an alert on the secondary effects of VR. In the VR experiment, participants were asked to accomplish a task in a virtual environment (VE) related with other study. Findings suggest that for those who read the consent form carefully, thus, were more aware about VR side effects, there were more symptoms of cybersickness and more withdraws. These reported results rise some practical and also ethical issues related with VR experiments that are discussed in this paper.

Previous studies [1], showed that in a T-type corridor, the brightness acted as factor of attraction improving the affordance of that corridor in an emergency egress situation Here, we test this effect in children. Participants were presented with an adapted narrative of a fire inside a school. Their task was to choose which of the two corridors they would follow to leave school. We used T-type intersections in which one corridor (left or right) was brighter than the other. Bright corridors were chosen 48% for group aged 3 to 6 years, 65% for group aged 7 to 10 and 90% for adults. Results can be interpreted as children looking at affordances in a different way than adults, what might have implications in the design of safety built environments.

An interesting approach to consider when studying human wayfinding behavior within buildings, namely considering the detection of visual stimuli, is the use of psychophysics methods. This paper aims to discuss the use of stimulus presentation comparing three methodological approaches. Three types of stimulus presentation with an increasing increment of visual information and interaction were considered: (i) constant stimuli method with fixed images, (ii) constant stimuli method with movies, and (iii) virtual reality simulation of a real environment. For this, the results of three studies were analyzed in order to verify the existence of agreement between users’ route-choices. Findings suggest, as expected, that increasing the visual information and interaction level also increase the results dispersion.

There are already works that study the effectiveness of safety signals in emergencies, evaluating which the people prefer to move along in the corridor, the results shown that, in a “T-type” intersection, users randomly chose which direction to follow. However, if there is an increment in the width of the side corridor, users tend to follow the wider corridor. When light is inserted, users also prefer to choose the corridors with more lighting .[1] The objective of this preliminary study is evaluate the efficacy of a virtual involvement to study decision making situations in a hurry situations with influence of others, where these others people will move in one direction, and will be checked if target audience will continue to walk by the normal route or will follow the others. The results show the people really might exert some influence in our decision making, the virtual involvement is effective for the study, but some adjustments were to be revised to increase immersion of the participants in the experiment, such as narrative and the interaction of virtual agents (VA) with the avatar.

However, the application of this tool still needs to be widely consolidated, mainly in teaching theoretical subjects related to the field of design, such as the History of Architecture and Urbanism. In addition, only some publications still discuss the advantages of using VR on this theme. The objective of this research is to map the scientific articles published in the last 25 years related to the use of virtual reality in teaching the history of architecture and urbanism. The scientific research sites ScienceDirect.com, CuminCad.org and GoogleScholar.com were chosen to perform data collection. The keywords "history of architecture", "virtual reality" and "learning" were used in the advanced search of each of the three sites mentioned. Subsequently, a two-stage filtering was carried out, the first related to reading the titles and the second aimed at reading the abstracts. Finally, the works found were all classified according to their own methodology, as well as their main contributions were identified. The main conclusion from this study is that, although VR is not yet consolidated in most architecture courses, especially in history teaching, the studies showed several benefits of applying the tool. However, the ways to do so still require further investigation, especially considering the emergence of new applications that are increasingly easy to use.

Electrodermal activity was used to detect users' emotional arousal, while navigating in VR. Navigation conditions and participants' expertise with games were controlled. Main results show that physiological measurement of user's perceptions can discriminate well "positive" from "negative" spaces, providing designers with basic information on people's emotional state when using the buildings they design.

We describe in detail the addressed educational skills and the developed research and we highlight the contributions towards the improvements of teaching and learning in those areas. We discuss in detail the role of Digital technologies, such as Virtual Reality, Augmented Reality, Multimedia, 3D Modelling software systems, Design Processes and its evaluation tools, such as Shape Grammar and Space Syntax, within the Architecture curricula.
