Mixed reality is the next big thing for construction technologists

by CW Staff on Aug 2, 2018 


The construction sector has been among the prominent adopters of virtual reality (VR) systems, with a number of companies testing out the technology, mainly in areas such as design visualisation.


With improvements to the technology, and new ideas coming out of the proof-of-concept projects, even more companies are looking to VR – and more specifically, mixed reality (MR) – to improve processes in a wide range of scenarios.



MR is helping to bridge operational gaps in the construction sector.

건설 분야는 주로 설계의 시각화를 위해서 많은 기업들이 이 기술을 시험하는 VR(VirtualReality)시스템을 적용하는 분야 중 하나였다.

기술의 발전과 새로운 아이디어로 인해 더욱 구체적으로 프로세스를 개선하기 위해 VR(그리고 MR)을 찾는 기업이 늘어나고 있다. 


MR에서 가능성을 가장 빨리 발견한 회사는 트림블(Trimble)이다. 이 회사는 약 3년 전에 마이크로 소프트 홀로렌 기술을 이용하여 몇가지 초기 프로젝트를 실시했고, 그 이후부터 MR기술을 사용하는 고객들이 자체 시스템을 사용할 수 있게 만들었다. 교육, 품질 관리 및 생산 환경뿐만 아니라 설계 및 아키텍처를 다루는 기능에 적합하다.


VR와 MR의 차이를 주목하는 것이 일단 중요하다. 전자는 전체적으로 가상 환경을 제공하는 반면 MR은 실제 환경과 가상 환경의 조합이다. 

간단히 말해, MR은 실제 환경에서 제시된 가상 개체의 예로서 물리적 개체와 디지털 개체가 실시간으로 공존하고 상호 작용한다.


트림블의 MR프로그램 책임자인 Aviad Almagor는 개념 증명 프로젝트가 완료된 후 이 회사는 고객들과 긴밀하게 협력하여 테스트 계획을 시작했다고 설명한다.상업화 하기 전에 우선 그들의 요구를 들어주었다.


트림블이 MR플랫폼을 개발하는 주된 요인은 기업들이 이미 빌딩 정보 모델링(BIM)이나 디지털 모델과 같은 시스템으로부터 막대한 양의 데이터를 생성하고 있다는 것이다. 데이터와 디지털 세계를 물리적 세계와 연결할 수 있어야 하기 때문이다.


"고객은 디지털과 물리적 환경 간의 격차, 원격 위치에 있는 동료와의 격차, 작업에 대한 정신적 모델 간의 격차로 어려움을 겪고 있으며.수행할 작업과 실제 작업을 수행했다. 


이러한 모든 격차는 효율성, 품질 관리, 안전성 등과 관련된 문제를 야기한다. MR, 우리는 디지털 세계와 물리적 환경을 통합할 수 있는 방법으로 이러한 격차를 해소하고 있다

One company that was quick to see the potential in MR is Trimble. The firm conducted a few early projects using Microsoft HoloLens technology around three years ago, and from there, has progressed to making its own systems available to customers using MR technology, for functions covering design and architecture, as well as training, quality control, and production environments.




It is important to note the difference between VR and MR – the former presents an entirely virtual environment, while MR is a combination of real and virtual. Put simply, MR is exemplified as a virtual object presented in a real setting, with both the physical and digital objects co-existing and interacting in real time.


Aviad Almagor, director of the MR programme at Trimble, explains that following the completion of a proof-of-concept project, the company launched pilot schemes by working closely with customers to understand their requirements, before moving onto commercial products.


The main driver for Trimble to develop MR platforms is that companies are already generating huge amounts of data from systems such as building information modelling (BIM) or digital models, but there is a need to be able to connect that data and the digital world with the physical.


“We can summarise what we learned [through market interaction] in one word: ‘gaps’,” Almagor tells Construction Week.


“Customers are suffering from gaps between the digital and physical, gaps between themselves and a co-worker in a remote location, and gaps between the mental model they have about the task that they need to perform, and the actual task. All those gaps create issues with efficiency, quality control, safety, and so on; MR, we realised, can actually bridge those gaps in ways that can merge the digital world with the physical environment.”


By utilising an MR environment, which projects digital plans onto the real world and allows users to share models in a three-dimensional environment, it is much easier to understand a concept or a scope of work, and even to see discrepancies between what needs to be done and the situation on site.


Trimble has developed three systems that incorporate MR using HoloLens. This includes Connect for HoloLens, a construction management software; SketchUp Viewer for HoloLens, a design framework; and Connected Mine Visual Intelligence, created for the mining sector. In addition to the software systems, the company has also integrated a Microsoft HoloLens rig into a safety helmet, allowing for easy use of the equipment on site. The focus of Trimble’s MR programme is currently on construction and mining, Almagor says, but there is potential across all areas of its operations.


      


The systems are already having an impact on customers. Concrete prefab manufacturer, Consolis, is exploring a system that will allow workers assembling complex concrete elements to see the 3D models and plans in front of them while they work, instead of having to move back and forth between 2D plans or onscreen models. French company GA Smart Building is using the hard hat HoloLens with Trimble systems for quality control inspections on site.


Trimble has also worked with architect Greg Lynn for the redesign of the Packard Plant in Detroit, US, where the architect was able to develop complex designs and communicate them in 3D. This was exhibited at the Venice Biennale in 2016.


The ability to take the digital world and bring it into the real world is a huge development, Almagor says: “There is a synergy between MR and other trends – in construction, it is all about BIM. Our customers invest a huge amount of effort in developing 3D models, but they consume these models on 2D screens.


“With MR, you can take those models out of the constraints of being in a 2D frame, and have much better interaction. The level of engagement for themselves and for their customers provides a huge benefit in terms of communication. One of the things we were really surprised about was the power of real 3D visualisation, compared to 3D on screen. When I saw the customers interact with it, the level of engagement is totally different,” he adds.


Users being able to work together in a MR environment, whether they are actually in the same space or connecting in from different locations, also has a big impact on the ability to collaborate and communicate, Almagor explains: “It is good if the users are isolated in their holographic experience, but once you add more people to the session and see the avatars of the other partners, you start communicating, you see what they are looking at. With Trimble Connect and SketchUp Viewer, this has opened up a completely new level of interaction.”


To support this adoption, Trimble has two professional services teams working in various, areas including integrating BIM into MR. At the customer level, Almagor says he is seeing demand both from innovation teams that are tasked with exploring new technology, and from the project teams that are getting an understanding of how the technology can help them to deliver better. Almagor says he expects MR technology to move beyond visualisation into object creation and editing in the future, and to include more support for Internet of Things objects, as well as artificial intelligence. The initial systems from Trimble are already in use with thousands of users, he says, and the technology is bringing tangible benefits to the bottom line.


“HoloLens is not mainstream yet, but looking at the process in the last three years, we have gone from [customers that] have the vision to gain first-mover advantage, to more conservative companies that really understand this is not just  a trend, and that there is real value behind it,” he says.




“Part of the success is to identify the right set of cases that the technology can support – quality control, training, improving safety, production control, communication, and so on. If you focus on those uses, then you can improve productivity and efficiency.”
