Collecting 3D point cloud data of buildings is important for many applications such as urban mapping, renovation, preservation, and energy simulation. However, laser-scanned point clouds are often ...difficult to analyze, visualize, and interpret due to incompletely scanned building facades caused by numerous sources of defects such as noise, occlusions, and moving objects. Several point cloud scene completion algorithms have been proposed in the literature, but they have been mostly applied to individual objects or small-scale indoor environments and not on large-scale scans of building facades. This paper introduces a method of performing point cloud scene completion of building facades using orthographic projection and generative adversarial inpainting methods. The point cloud is first converted into the 2D structured representation of depth and color images using an orthographic projection approach. Then, a data-driven 2D inpainting approach is used to predict the complete version of the scene, given the incomplete scene in the image domain. The 2D inpainting process is fully automated and uses a customized generative-adversarial network based on Pix2Pix that is trainable end-to-end. The inpainted 2D image is finally converted back into a 3D point cloud using depth remapping. The proposed method is compared against several baseline methods, including geometric methods such as Poisson reconstruction and hole-filling, as well as learning-based methods such as the point completion network (PCN) and TopNet. Performance evaluation is carried out based on the task of reconstructing real-world building facades from partial laser-scanned point clouds. Experimental results using the performance metrics of voxel precision, voxel recall, position error, and color error showed that the proposed method has the best performance overall.
The current study investigates the neural correlates when processing prototypicality and simplicity-affecting the preference of product design. Despite its significance, not much is known about how ...our brain processes these visual qualities of design when forming design preferences. We posit that, although fluency is the perceptual judgment accounting for the positive effects of both prototypicality and simplicity on design preference, the neural substrates for the fluency judgment associated with prototypicality would differ from those associated with simplicity. To investigate these issues, we conducted an fMRI study of preference decisions for actual product designs with different levels of prototypicality and simplicity. The results show a significant functional gradient between the preference processing of simplicity and prototypicality-i.e., involvement of the early ventral stream of visual information processing for simplicity evaluation but recruitment of the late ventral stream and parietal-frontal brain regions for prototypicality evaluation. The interaction between the simplicity and prototypicality evaluations was found in the extrastriate cortex in the right hemisphere. The segregated brain involvements suggest that the fluency judgment for prototypicality and simplicity contribute to preference choice in different levels of cognitive hierarchy in the perceptual mechanism of the design preference.
Consumers often rely on observable cues that hint at the hidden quality of a product. The aim of this study was to investigate brain activities associated with the country-of-origin (COO) effect and ...consumer evaluation of a product design. Electroencephalogram recordings were used to observe event-related brain potentials associated with the COO effect and design evaluation. We found that the frontocentral N90 and parieto-occipital P220 amplitudes are involved in forming preference to design, whereas the COO effect is processed in the centroparietal P500 amplitude. We also found a significant interaction effect between COO and design preference with regard to reaction times. Specifically, participants tended to spend more time making a preference decision when they did not like the product design made in a country with a favorable COO. These results imply that the two cognitive processes, evaluation of COO and formation of design preference, are activated independently at an early stage. It also suggests that these two processes interact with each other toward the end of the decision phase. Together, the results of this study provide neuropsychological evidence supporting a significant role of COO in the formation of design preference. Future studies are required to further delve into other neurophysiological activities associated with the COO effect.
This study sheds light on a prominent issue in retailing: how the digital atmosphere can affect the consumer decision-making process in a fashion retail store. Digital devices and services such as ...digital screens and digital signage are widely employed in fashion retail stores, transforming the way consumers make decisions about purchasing fashion products. This research investigates how the digital atmosphere affects consumers’ purchase behavior patterns based on the attention-interest-desire-search-action-share (AIDSAS) model. The findings show that attention is a key antecedent to interest, desire, and behavioral responses (search, action, and share) triggered by the digital atmosphere. The findings further suggest that attention has significantly positive effects on consumers’ purchasing patterns of utilizing the digital atmosphere in two types of fashion retail stores: sports and luxury stores. However, we find that these positive effects are more pronounced for sports retail stores than luxury retail stores. This research contributes to understanding consumer behavior related to the digital atmosphere of fashion retail stores by applying the AIDSAS model and helps uncover the stepwise relationships between attention to the store atmosphere-interest/desire and the products-behavior response. These findings have practical implications that can be applied in the fashion industry.
To enable organizations to achieve carbon neutrality through agile capabilities, this paper establishes an integrative framework of carbon-zero agility consisting of three dimensions: search scope ...agility, search locus agility, and search pace agility. However, applying common agile methodologies like Scrum, Kanban, and Lean to cultivate these capabilities inevitably introduces feedback ambiguity, which can paralyze decision-making and increase errors due to inherent human cognitive limitations. To address this, tailored carbon-zero feedback algorithms are proposed to complement human judgment in agile workflows. Specifically, prescriptive analytics, federated learning, and probabilistic programming are injected into Scrum, Kanban, and Lean respectively to restore clarity amidst ambiguity. The framework is grounded in cases from the textile industry to demonstrate applicability in practical settings. By targeting the roots of distortions with human-algorithm collaborations, it provides an actionable roadmap to implement carbon-zero agility.

This study examines how users accept the information from mobile Word-of-mouth (MWOM) information communication. In so doing, we investigate the role of both trust and distrust affecting the degree ...to which users would accept the recommendation made by MWOM and refer the information to other users. Furthermore, we identify specific evaluative judgments critical in enhancing trust and engendering distrust. We then examine the moderating role of event significance and the aggregate preference by other users reflected by the number of likes. The results indicate that trust has a greater influence than distrust in determining the information acceptance and referral of the recommendation made by MWOM. We also find that source expertise, message relevance, and altruism are more significant in inducing trust, while self-interest seeking is more critical in engendering distrust. The results show that our model is robust against different levels of event significance and the number of likes, although the relative significance of a few paths differs by these two moderating variables.
This study investigates the mechanism by which trust is formed and affects collaboration in virtual teams. In so doing, we identify the judgement dimensions involved in determining interpersonal ...trustworthiness (i.e., ability, benevolence, integrity and goal congruence) and systems through which virtual interactions are organized and executed (i.e., system performance, system design, and system assurance). We also examine the way in which trust influences three distinct aspects of collaboration (i.e., cooperation, coordination, and knowledge sharing). Further, we investigate whether trust and collaboration would be affected by the culture of autonomy and task complexity. The proposed hypotheses were tested with data from 483 respondents collected in South Korea. The results find that coordination and cooperation enhance knowledge sharing and that trust is critical in determining all aspects of collaboration. We find that ability, integrity, and goal congruence as well as system performance and system design are significant in forming trust. The results also indicate that virtual teams with strong autonomy have greater trust and collaboration than those with weak autonomy. Virtual teams carrying out complex tasks exhibit higher trust and collaboration than those working on simple tasks.
•Cooperation and coordination enhance knowledge sharing in virtual teams.•VTT enhances all three dimensions of collaboration.•VTT is determined by ability, integrity, and goal congruence of team members.•VTT is affected by system performance and system design.•Autonomy and task complexity affect the level of trust and collaboration.
We investigate factors affecting tourists' intentions to revisit and recommend a travel site they visited before. The results indicate that delight (i.e., holistic emotional evaluation), more so than ...satisfaction, determines revisit and referral intentions. We also find that delight is affected by the extent to which one perceives his/her travel experience to have engendered self-enhancement. The assessment of self-enhancement is significantly influenced by both real and ideal self-congruence judgments. In addition, we examine the roles of variety-seeking and the need for uniqueness on tourists' patronage intentions. We find that the higher variety-seeking and the need for uniqueness, the more likely one will revisit and recommend the site he/she visited before.
