Blocks World Redux: Formalizing Material Interaction in Exploratory Model-Making

Blocks World Redux: Formalizing Material Interaction in Exploratory Model-Making

How do architects think through interaction with physical models? In this study we codify model making in terms of picking, transforming, and placing blocks to compare the interactions of architects and students. 

Learning from Interaction for Robotic Programming

Learning from Interaction for Robotic Programming

Can the way we think with our hands be automated with robotic technologies? This study reveals human techniques observed in simple manipulation tasks and develops robotic programs that embed this know-how.

Robotic Fabrication and Assembly Systems

Robotic Fabrication and Assembly Systems

How can robotic tools consolidate the fabrication and assembly processes? Through workshops and undergraduate research projects we initially investigate stand-alone assembly systems for planar construction.

Taming the Wild Horses: Digital Fabrication in Singapore

Taming the Wild Horses: Digital Fabrication in Singapore

In collaboration with computer scientists in Singapore (SUTD) I developed a 3-axis digital-to-physical translation algorithm for generating high fidelity planar construction prototypes.

Spatial Cognition in Planar Assemblies

Spatial Cognition in Planar Assemblies

In this study we explore the cognitive challenges of the complex assembly involved in digitally fabricated planar construction. We devised interlocking jigsaw puzzles.

A Physical Design Computing Environment

A Physical Design Computing Environment

How can the work space of design activity change with interactive computing technology? We develop a simple solution to work in real-time with a robotic manipulator arm.

Slide Rule: Digitally Fabricated Analog Calculator

Slide Rule: Digitally Fabricated Analog Calculator

According to the Oughtred Society, this is the world’s first digitally fabricated analog calculator. This simple device pushes the limits of current 3D printing technology but raises the possibility for analog computation to surpass digital computing power.

The Parallelepiped: A Study in Symmetry

The Parallelepiped: A Study in Symmetry

Symmetry makes things predictable. That’s why cubes are boring shapes for designers. Rotate them along 13 different axes and you will see the same thing. I designed a set of 3D-printed blocks based on a special geometry that is surprisingly asymmetrical - the parallelepiped. While it looks like a cube it behaves differently from one when you manipulate it.

Interactive Computational Reasoning

Interactive Computational Reasoning

This study explores how humans interact with physical material in computational terms such as copying, rotating, arraying, and reflecting. Why and how are some people better than others? In what ways do they interact that can be observed through video analysis?

Mental vs Physical Rotation

Mental vs Physical Rotation

Given two identical tasks of rotating blocks, one in which you could manipulate physical blocks and the other only mentally, which would you do faster? We found people struggle more with physical rotation. Why is this?
