pARam: Leveraging Parametric Design in Extended Reality to Support the Personalization of Artifacts for Personal Fabrication
arxiv(2024)
摘要
Extended Reality (XR) allows in-situ previewing of designs to be manufactured
through Personal Fabrication (PF). These in-situ interactions exhibit
advantages for PF, like incorporating the environment into the design process.
However, design-for-fabrication in XR often happens through either highly
complex 3D-modeling or is reduced to rudimentary adaptations of crowd-sourced
models. We present pARam, a tool combining parametric designs (PDs) and XR,
enabling in-situ configuration of artifacts for PF. In contrast to modeling- or
search-focused approaches, pARam supports customization through embodied and
practical inputs (e.g., gestures, recommendations) and evaluation (e.g.,
lighting estimation) without demanding complex 3D-modeling skills. We
implemented pARam for HoloLens 2 and evaluated it (n=20), comparing XR and
desktop conditions. Users succeeded in choosing context-related parameters and
took their environment into account for their configuration using pARam. We
reflect on the prospects and challenges of PDs in XR to streamline complex
design methods for PF while retaining suitable expressivity.
