Smart adaptation of BIM for virtual reality, depending on building project actors’ needs: the nursery case

Nowadays, virtual reality (VR) is widely used in the AEC (architecture, engineering and construction) industry. One crucial issue is how to reuse Building Information Modeling (BIM) models in VR applications. This paper presents an approach for a smart adaptation of BIM models for using in VR scene, by following the needs expressed by building projects actors. The main adaptation consists in filtering BIM data to keep the necessary ones for VR, according to the user objectives. Moreover, VR system should be chosen by taking into account the purpose of usage of the VR model. This approach is applied to a study case of a nursery building project

Understanding the challenges of immersive technology use in the architecture and construction industry: A systematic review

Despite the increasing scholarly attention being given to immersive technology applications in the architecture and construction industry, very few studies have explored the key challenges associated with their usage, with no aggregation of findings or knowledge. To bridge this gap and gain a better understanding of the state-of-the-art immersive technology application in the architecture and construction sector, this study reviews and synthesises the existing research evidence through a systematic review. Based on rigorous inclusion and exclusion criteria, 51 eligible articles published between 2010 and 2019 (inclusive) were selected for the final review. Predicted upon a wide range of scholarly journals, this study develops a generic taxonomy consisting of various dimensions. The results revealed nine (9) critical challenges which were further ranked in the following order: Infrastructure; Algorithm Development; Interoperability; General Health and Safety; Virtual Content Modelling; Cost; Skills Availability; Multi-Sensory Limitations; and Ethical Issues

Influence of color in a lactation room on users affective impressions and preferences

[EN] Objective: The present study aims to examine the influence of environmental color hue in a lactation room at a health center on users' affective response and preference. Background: Hospital design plays an important role in the emotional experience of patients. In this regard, many studies have attempted to find relationships between design variables and healthcare facilities users' response. Color has been frequently examined because it is always present in the environment and can be easily changed. However, most of the studies dealing with color-emotion relationships acquire users' affective response by questionnaires developed by experts which could lead to inaccurate results since nonexperts may misunderstand concepts set by experts and use nonimmersive images to simulate the environments to assess. Methods: To overcome these limitations, a Kansei Engineering-based approach was proposed. In the first phase, users' specific affective factors for lactation rooms were determined using Semantic Differential. In the second phase, the influence of nine different color hues on users' affective factors was obtained. An immersive display system was used to visualize the room altering hues in an isolated and controlled way. Results: (1) Six user's affective factors connected to the lactation rooms were discovered: safety, elegance, coziness, spaciousness, simplicity, and luminosity, of which coziness has the most impact on the assessment of the room. (2) Warm colors like orange and yellow tend to score highly for coziness which puts them in leading positions when users' assess lactation rooms. Conclusions: Results provide recommendations for designers and show the advantages of using semantic differential and immersive displays to analyze user's affective response to environments.The authors disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was supported by the Ministerio de Economia y Competitividad.

VR-assisted architectural design in a heritage site: the Sagrada Família case study

Virtual Reality (VR) simulations have long been proposed to allow users to explore both yet-to-built buildings in architectural design, and ancient, remote or disappeared buildings in cultural heritage. In this paper we describe an on-going VR project on an UNESCO World Heritage Site that simultaneously addresses both scenarios: supporting architects in the task of designing the remaining parts of a large unfinished building, and simulating existing parts that define the environment that new designs must conform to. The main challenge for the team of architects is to advance towards the project completion being faithful to the original Gaudí’s project, since many plans, drawings and plaster models were lost. We analyze the main requirements for collaborative architectural design in such a unique scenario, describe the main technical challenges, and discuss the lessons learned after one year of use of the system.Peer ReviewedPostprint (published version

Enhancing the Usability, Visibility, and Responsiveness of an Airline Reservation System: A User-Centered Design Approach

This paper presents the idea, design, and prototype of a flight search and airline booking system based on the perspective of user-centered design. The system is first sketched roughly on paper in the form of a sketched plan and implemented through the proper system by connecting with the rapid API to develop a responsive web application. Booking travel tickets is a hassle and quite stressful because there is a chance that the webpages take time, and several decisions to make, hard to choose a discounted or less expensive flight, and the user will have to put in a lot of effort with many browser tabs may leave open. If a user is looking for the lowest travel options within a range of dates, they need to search a lot of websites looking for better options. As UX designers, it is our responsibility to do some user research and identify the problem areas, then we will recommend some design options based on the research findings. After that, we will create a wireframe and prototype before jumping into web design by collecting all the requirements and analyzing the problems. We will be focusing on UI controls such as location picker, date picker, color contrast, accessibility, and so on. In this paper, we present the design and development of a user-centered flight search and booking system for the airline industry. Our goal is to create a system that would meet the needs and preferences of a diverse set of users. This paper will summarize the design, development, and implementation of an airline reservation system. We have used bubble.io to design the overall system and MYSQL as the database management system for this webpage. Our objective is to upgrade the current website by improving the usability, visibility, and responsiveness of the functions that the user will experience while buying a flight ticket. We have generated and managed the design documentation and a perfect user-based online flight booking system

Digitaalisuudella tehokkuutta liiketoimintaan

Tässä julkaisussa keskitytään siihen, kuinka digitaalisuus näkyy erityisesti pk-yrityksissä ja valmistavan teollisuuden aloilla. Digitaalisuus haastaa uudistumaan ja ajattelemaan toisin. Yhteiskehittämisalustat ja erilaiset innovaatioekosysteemit tarjoavat hedelmällisen alustan uusien toimintojen kehittämiseen. Tiina Tervaniemen artikkelissa käsitellään juuri näitä innovaatioekosysteemejä verkostomaisen kehittämisen alustoina. Kaupan ja palveluiden ala on tarkastelussa Heli Aaltosen artikkelissa, jossa käsitellään Digitaalisuudella verkkokauppaa. Verkkokauppiaat ovat usein uuden edessä, sillä verkkokaupassa myyminen vaatii myyntiosaamisen lisäksi myös teknologian tuntemusta ja kykyä hyödyntää sitä. Aaltonen jatkaa toisessa artikkelissa digitaalisesta kaupankäynnistä ja markkinoinnista ja tuo videot osaksi sisältömarkkinointia. Anna-Maija Torniaisen artikkelissa on pohdittu suomalaisten pk-yritysten uudistumisen esteitä. Työn tuottavuutta on suomalaisissa pk-yrityksissä haettu pikemminkin säästöjen kautta kuin uusilla innovaatioilla tai panostamalla digitaalisuuteen. Kuitenkin tutkimuksissa on todettu juuri voimakkaasti kasvavien yritysten olevan samalla digitalisaatiota voimakkaimmin hyödyntäviä yrityksiä. Tiina Maarasen artikkelissa tarkastellaan, kuinka työhyvinvointi voisi kasvaa uudella koulutuksella ja koulutuksen seurauksena työn uudenlaisella organisoinnilla. Timo Partalan artikkelissa pohditaan digitaalisaation vaikutuksia ja erityisesti rakennusten tietomallien hyödyntämisen mahdollisuuksia rakennusalalla. Uusina teknologioina virtuaalitodellisuus, lisätty todellisuus ja tehokkaat simuloinnit voivat muuttaa tulevaisuuden rakennussuunnittelua merkittävästi. Tämä julkaisu on toteutettu Digitaalisuudella ja prosessien hallinnalla tuottavuuteen – hankkeessa. Hankkeen tavoitteena oli yhtäältä lisätä digitaalisuuteen liittyvää osaamista pk-yrityksissä ja toteuttaa yhdessä yritysten kanssa valmennuspilotti, jossa korostuvat vertaisoppiminen ja verkottuminen. Toisaalta tavoitteena oli käynnistää Etelä-Savon teknologia- ja prosessiteollisuusyrityksissä systemaattinen kehittämisprosessi tuotannon tuottavuuden parantamiseksi ja kehittää näin yritysten kansainvälistä kilpailukykyä. Julkaisussa on haluttu ottaa laajempi useita eri toimialojen pk-yrityksiä hyödyttävä näkökulma digitaalisuuden murrokseen ja työn tuottavuuteen. Lisäksi pohditaan ihan uusien innovaatioiden ja markkinoiden syntyä. Digitalisaation hyödyntäminen pk-yrityksissä kysyy ennen kaikkea rohkeutta innovoida uusia tuotteita ja palveluita sekä uskoa tulevaisuudessa oleviin mahdollisuuksiin. Digitalisaation huomattavan nopeasta kehityksestä huolimatta, monet digitaaliset ratkaisut ovat sellaisia, joista on olemassa enemmän tulevaisuuden lupauksia kuin tutkittua ja toteen näytettyä tietoa tuottavuuden parantumisesta. Digitaalisuuden voimakas hyödyntäminen tuo kuitenkin lähes alalla kuin alalla yritykselle merkittävän kilpailuedun

Design agency:prototyping multi-agent systems in architecture

This paper presents research on the prototyping of multi-agent systems for architectural design. It proposes a design exploration methodology at the intersection of architecture, engineering, and computer science. The motivation of the work includes exploring bottom up generative methods coupled with optimizing performance criteria including for geometric complexity and objective functions for environmental, structural and fabrication parameters. The paper presents the development of a research framework and initial experiments to provide design solutions, which simultaneously satisfy complexly coupled and often contradicting objectives. The prototypical experiments and initial algorithms are described through a set of different design cases and agents within this framework; for the generation of façade panels for light control; for emergent design of shell structures; for actual construction of reciprocal frames; and for robotic fabrication. Initial results include multi-agent derived efficiencies for environmental and fabrication criteria and discussion of future steps for inclusion of human and structural factors
