RevoMaker: Enabling Multi-directional and Functionally-embedded 3D Printing using a Rotational Cuboidal Platform

RevoMaker: Enabling Multi-directional and Functionally-embedded 3D Printing using a Rotational Cuboidal Platform

Nov 5, 2015

In recent years, 3D printing has gained significant attention from the maker community, academia, and industry to support low-cost and iterative prototyping of designs. Current unidirectional extrusion systems require printing sacrificial material...

Extracting Hand Grasp & Motion for Intent Expression in Mid-Air Shape Deformation: A Concrete & Iterative Exploration through a Virtual Pottery Application

Extracting Hand Grasp & Motion for Intent Expression in Mid-Air Shape Deformation: A Concrete & Iterative Exploration through a Virtual Pottery Application

Oct 25, 2015

We describe the iterative design and evaluation of a geometric interaction technique for bare-hand mid-air virtual pottery. We model the shaping of a pot as a gradual and progressive convergence of the pot-profile to the shape of the user's hand...

A Collaborative Filtering Approach to Real-Time Hand Pose Estimation

A Collaborative Filtering Approach to Real-Time Hand Pose Estimation

Aug 31, 2015

Collaborative filtering aims to predict unknown user ratings in a recommender system by collectively assessing known user preferences. In this paper, we first draw analogies between collaborative filtering and the pose estimation problem....

Bridging The Gaps: Augmenting Design Learning Through Computer-Aided Exploration

Bridging The Gaps: Augmenting Design Learning Through Computer-Aided Exploration

Aug 30, 2015

ABSTRACT In helping students learn engineering design, it is very important that they explore complex scenarios that are realistic, and fall outside the domain of standard and over-simplified textbook problems that typically have an answer. A...

Empirical Studies of Functional Decomposition in Early Design

Empirical Studies of Functional Decomposition in Early Design

Aug 11, 2015

This paper explores functional decomposition in early design. In the first part of this study, we explore how the three most common methods (top-down, energy-flow, enumeration) affect concept generation for novice design teams (n=25). We found that...

Comparing Functional Analysis Methods for Product Dissection Tasks

Comparing Functional Analysis Methods for Product Dissection Tasks

Aug 10, 2015

The purpose of this study is to begin to explore which function identification methods work best for specific tasks. We use a three-level within-subject study (n ¼ 78) to compare three strategies for identifying functions: energy-flow, top-down,...

MotionFlow: Visual Abstraction and Aggregation of Sequential Patterns in Human Motion Tracking Data

MotionFlow: Visual Abstraction and Aggregation of Sequential Patterns in Human Motion Tracking Data

Jul 17, 2015

Pattern analysis of human motions, which is useful in many research areas, requires understanding and comparison of different styles of motion patterns. However, working with human motion tracking data to support such analysis poses great...

A framework for visualization-driven eco-conscious design exploration

A framework for visualization-driven eco-conscious design exploration

Jul 17, 2015

A large portion of design activity involves applying previous design knowledge in order to solve new problems. Therefore, facilitating eco-conscious exploration of archived designs is needed for advancing sustainable product design. It is thus...

Mutually coordinated visualization of product and supply chain metadata for sustainable design

Mutually coordinated visualization of product and supply chain metadata for sustainable design

Jul 17, 2015

In this paper, we present a novel visualization framework for product and supply chain metadata in the context of redesign-related decision scenarios. Our framework is based on the idea of overlaying product-related metadata onto the interactive...

HandiMate: Exploring a Modular Robotics kit for Animating Crafted Toys

HandiMate: Exploring a Modular Robotics kit for Animating Crafted Toys

Jun 17, 2015

Building from our previous work we explore HandiMate, a robotics kit which enables users to construct and animate their toys using everyday craft materials [32]. The kit contains eight joint modules, a tablet interface and a glove controller....
