A spectrum of new augmented, virtual, and mixed-reality technologies promise to fundamentally change how landscape architects and designers plan, design, collaborate, construct, and manage projects. At the ASLA 2017 Annual Meeting in Los Angeles, Matthew Wilkins, ASLA, KTU+A Planning and Landscape Architecture; David Leonard, ASLA, Parsons; and Ryan Deane, ASLA, the Slam Collaborative argued that of all these new technologies, perhaps mixed-reality technologies, like the HoloLens, may have the greatest potential to change how designers work.
Augmented reality (AR) comprises technologies that layer location-based data on existing reality. Pokemon Go, the popular game that had thousands out searching their neighborhood for pikachus, is a prime example. Virtual reality (VR) is an “immersive interaction” using 360 video, explained Leonard. 360 videos can take the form of games, animations, or videos of the real world.
In contrast, mixed reality, or hybrid reality, is about “merging virtual and real worlds so you can interact with the world in real-time.” This technology enables a landscape architect to don glasses and create a SketchUp model overlaid on the scene they are looking at in real time, all with the swipe of their hands or pinch of their fingers. Other designers nearby or on the other side of the globe can join in and collaborate as well.
According to Leonard, “creating a hologram of a design on-site is where things are going. The technology won’t stop until that happens.” He also warned that “other professions will dominate this technology fast if landscape architects don’t get on board.”
Within these virtual worlds, landscape architects can appear as avatars, working together or with engineers or construction managers to “create SketchUp models, make changes to design parameters, or solve issues.” Working together in a virtual model, “they can get a sense of the size and scale of objects.”
Leonard noted that the HoloLens is still “first generation, with a limited field of view. It’s like looking at a little pane, so it’s not fully immersive at this point.” Magic Leap, Lord of the Rings director Peter Jackson’s new media company, is expected to take mixed-reality up a notch, given they’ve already raised $1.9 billion in funding.
Leonard went through many of the leading hardware and software options for AR, VR, and mixed reality, but noted “these technologies are just now coming out of their infancy.”
On the software front, Leonard discussed the benefits and drawbacks of AR Media for augmented reality, which costs $300 and uses geo-reference tracking technology so you can mark designs and data in real-world locations.
For virtual reality, he then discussed Lumen RT, which is “integrated into a lot of software and offers moderately-high-end quality, with a plant factory that enables you to make your own plants;” Fuzor 2018, which is “widely used in the construction and design industry, very powerful, and allows you to do ‘drag and drop rendering'”; Revit Live, which is “easy to navigate but doesn’t offer animations of designs”; and Autodesk 3DS Max, which offers “superior rendering, but is challenging to work with.”
For mixed-reality, Leonard mentioned SketchUp for HoloLens.
On the hardware front, for virtual reality, there’s Google cardboard glasses, which are cheap but have major latency issues that can cause fatigue; Samsung Gear VR, which cost around $100 and offers much better quality than the cardboard lens; Oculus Rift, which goes for $399 and is “very high quality;” HTC Vive, which is similar to Oculus Rift; and the just-announced Oculus Go, which will have a “high-resolution LCD screen and no cables or phones — the video will be accessed via WiFi.”
As for bringing these technologies into a design studio, Deane called for “assuming the start-up costs internally — don’t charge clients for this.” But then, moving forward, these technologies can be used to “reassure clients.” And, of course, firm CFOs will say “don’t do it for free.”
Wilkins demonstrated how KTU+A is already using these technologies, creating models, which are then rendered in virtual reality. As part of engagement, community groups are now reviewing proposals using headsets before they are designed and built.
