Cast-in-place Freeform Concrete with Big Area AdditiveManufacturing Formwork

Ming Tang, Noah Shroyer. Cast-in-place Freeform Concrete with Big Area AdditiveManufacturing Formwork. International Journal of Architecture, Engineering and ConstructionVol 10, No 2, Vol 10, No 2 (2021) 1-9

Abstract: Parametric design and digital fabrication give precise control in the design and materialization of complex geometric forms. Large-scale additive manufacturing machines can fabricate digitally generated architectural forms quickly and economically at full scale. However, their application in building construction has been limited. Through a case study, this paper examines integrating parametric design with material and constructed reality through 3D printed formwork for cast-in-place concrete. The following details are presented: (1) creating a parametric model capable of designing, testing, and manipulating the customized freeform in response to construction and material constraints, (2) fabrication method of big area additive manufacturing of formwork with carbon fiber-reinforced acrylonitrile butadiene styrene plastic, and (3) construction process (studying material behavior, testing the formwork, and the final onsite concrete cast)

This project was supported by the computation team led by Ming Tang, the design team led by Jose Garcia Design, the structural engineering team led by Pinnacle EngineeringInc, formwork and fabrication led by Cincinnati Incorporated. The project was constructed by the general contractor Jose Garcia Construction. The rebar shop fabrication was provided by Artistic Ironworks.

Visual Perception: Eye-tracking and Real-time Walkthroughs in Architectural Design

This paper discusses the application of Eye Tracking (ET) technologies as a new way for researchers to understand a person’s perception of a build environment regarding wayfinding and other spatial features. This method was beneficial for informing reviewers how an existing place or a proposed design was performing in terms of user experience. Combining ET with real-time walkthrough (RTW) and analytical platform allowed designers to make real-time changes and instantly see how these choices affected a user’s visual attention and interaction. This paper also presents a study investigating the architectural features emphasizing the simulated human behavioral cues and movement information as input parameters. The research is defined as a hybrid method that seeks augmented architectural experience, wayfinding and analyzes its’ performance using ET and RTW. While presenting their concepts through RTW, students used the Tobii Pro eye tracker and analytical software to investigate the attractiveness of the proposed experience related to the five spatial features: face, edge, intensity, blue-yellow contrast, and red-green contrast. The studio projects extended psychological architecture study by exploring, collecting, analyzing, and visualizing behavioral data and using the ET analysis to optimize the design presented through walking and driving simulations. ET allowed students in the transit hub design studio to investigate various design iterations about human perception to enhance spatial organization and navigation.

Abstract

Signs, in all their forms and manifestations, provide visual communication for wayfinding, commerce, and public dialogue and expression. Yet, how effectively a sign communicates and ultimately elicits a desired reaction begins with how well it attracts the visual attention of prospective viewers. This is especially the case for complex visual environments, both outside and inside of buildings. This paper presents the results of an exploratory research design to assess the use of eye-tracking (ET) technology to explore how placement and context affect the capture of visual attention. Specifically, this research explores the use of ET hardware and software in real-world contexts to analyze how visual attention is impacted by location and proximity to geometric edges, as well as elements of contrast, intensity against context, and facial features. Researchers also used data visualization and interpretation tools in augmented reality environments to anticipate human responses to alternative placement and design. Results show that ET methods, supported by the screen-based and wearable eye-tracking technologies, can provide results that are consistent with previous research of signage performance using static images in terms of cognitive load and legibility, and ET technologies offer an advanced dynamic tool for the design and placement of signage.

Cyber-Physical Experiences: Architecture as Interface

Turan Akman and Ming Tang’s Paper Cyber-Physical Experiences: Architecture as Interface was presented at the Artificial Realities: Virtual as an Aesthetic Medium for Architectural Ideation Symposium in Lisbon, Portugal. 2019.

Abstract:

Conventionally, architects have relied on qualities of elements such as materiality, light, solids and voids, etc. to break out of the static nature of space, and enhance the way users experience and perceive architecture. Even though some of these elements and methods helped create more dynamic spaces, architecture is still bound by conventional constraints of the discipline. With the introduction of technologies such as augmented reality(AR), it is becoming easier to blend digital, and physical realities, and create new types of spatial qualities and experiences, especially when it is combined with virtual reality(VR) early in the design process. Even though these emerging technologies cannot replace the primary and conventional qualitative elements in architecture, they can be used to supplement and enhance the experience and qualities architecture provides.

To explore how AR can enhance the way architecture is experienced and perceived, and how VR can be used to enhance the effects of these AR additions, the authors proposed a hybrid museum which integrated AR with conventional analog methods(e.g., materiality, light, etc.) to mediate spatial experiences. To evaluate the proposed space, the authors also created a VR walkthrough and collected quantifiable data on the spatial effects of these AR additions.
