The tools we use : a study of user preferences for sketches, prototypes, and CAD models and the influence on design outcome
During a product design and development process, design teams use a variety of tools to generate and represent multiple design options before they eventually arrive at a singular design solution. Studying how these tools can influence the design outcome has the potential to enable designers to …

Robot Graph Grammars: Towards Custom Robots for Every Task
… complex dynamics. Existing robots are largely designed by hand to meet a given set of specifications. While highly capable, these manually-designed robots tend to leave performance on the table. These difficulties have motivated research into automatic robot design tools. Early tools were often …

Geometric Properties of Learned Representations
… refers to optimizing a mapping from data to some representation space (usually generic vectors in Rᵈ for some pre-determined 𝑑 much lower than data dimensions). While such training often uses no supervised labels, the learned representations have proved very useful for solving downstream tasks. …

Supporting design: a computational theory of design and its implementation in a software support tool
… engineering to a broader class of problem: design. Design is examined as a generic activity, found in many fields of professional practice. A theoretical framework is developed that supports the refinement of design from high-level concepts through implementation. This framework includes a …

Researching on Multisensory Design Communication for Design Development and Collaboration among Designers and Stakeholders
Focusing on VR/AR-enhanced design representations, this research explores Multisensory Design Communication (MDC) in the context of design development and collaboration among design professionals and stakeholders. To address the differences between various groups of design participants, three …

Prototyping for user feedback : how visual detail can influence feature preference
User-centered design focuses on insights drawn from users to drive product development. Provisional design prototypes are often used as a tool for collecting feedback from users that can then be incorporated into future design iterations. However, experience from design practice suggests that user …

Approximate translation : media, narrative, and experience in urban design
Approximate translation is developed as a design process through which the place-embedded history of an urban environment can be understood, allowing for better design and intervention in that urban environment. Generally, approximate translation champions media, narrative, and experience as design …

Hierarchical volumetric object representations for digital fabrication workflows
Modern systems for computer-aided design and manufacturing (CAD/CAM) have a history dating back to drafting boards, early computers, and machine shops with specialized technicians for each stage in a manufacturing workflow. In recent years, personal-scale digital fabrication has challenged many of …

Design optimization for 2-D granular media with dissipation
… reaction force at the desired bead contacts. Two design approaches are presented: introducing interstitial beads and prescribing initial plastic compression in the system. Using the intruders presence or lack thereof as the design variable is a discrete optimization problem. It is necessary to …
