Augmented Reality for Digital Fabrication: Evaluating impact of AR visualization of machine toolpaths for Clay 3D printing

    Joyce Passananti, Ana Cardenas, Jennifer Jacobs, Tobias Hollerer
    IEEE ISMAR 2024
    Visualizing toolpaths in AR can help Cay 3D practitioners gauge, interpret, and plan machine behavior. To better understand the potential of AR to aid the understanding of machine toolpaths, we present a user study involving nine 3D printing practitioners with varying backgrounds. Weinvestigate the effectiveness of two AR modalities: head-worn (Hololens) and hand-held (iPad) in visualizing machine toolpaths to improve the design process for clay 3D printing, and compare with the baseline workflow of desktop-only visualization.

SculptAR: Direct Manipulations of Machine Toolpaths in Augmented Reality for 3D Clay Printing

    UIST Demo Track 2023
    With SculptAR we seek to support fabrication workflows where clay artists can previsualize and dimension their vessel in the fabrication context and manipulate the shape textures and forms created by these toolpaths in an immersive 3D context. By visualizing the machine toolpath directly, we allow clay artists to leverage their unique knowledge and experience of the material to design structurally sound vessels.

Level-of-Detail AR: Dynamically Adjusting Augmented Reality Level of Detail Based on Visual Angle

    A. Wysopal, V. Ross, J. Passananti, K. Yu, B. Huynh and T. Hollerer
    IEEE VR 2023
    Dynamically adjusting the content of augmented reality (AR) applications to efficiently display information best fitting the available screen estate may be important for user performance and satisfaction. We present a Level-of-Detail AR mechanism to improve the usability of AR applications at any relative size. Our mechanism dynamically renders textual and interactable content based on its legibility, interactability, and viewability respectively.

ThermalRouter: Enabling Users to Design Thermally-Sound Devices

    Alex Mazursky, Borui Li, Shan-Yuan Teng, Dasha Shifrina, Joyce Passananti, Svitlana Midianko, Pedro Lopes
    UIST 2023
    We created a CAD plugin that assists users with to improve the thermal performance of their models. ThermalRouter automatically converts regions of the model to be made from thermally-conductive materials (such as nylon or metallic-silicone). The key is that ThermalRouter automatically simulates the thermal performance of many possible heat channel configurations and presents the user with the most thermally-sound design (e.g., lowest temperature).

ecoEDA: Recycling E-waste During Electronics Design

    Jasmine Lu, Beza Desta, K. D. Wu, Romain Nith, Joyce Passananti, Pedro Lopes
    UIST 2023
    We present an interactive tool that enables electronics designers to explore recycling electronic components during the design process. We accomplish this via (1) creating suggestions to assist users in identifying and designing with recycled components; and (2) maintaining a library of useful data relevant to reuse (e.g., allowing users to find which devices contain which components).
