LMN Tech Studio, 2010-2012
Used a WiiMote to track IR-LED Light Pens and an under-table projection system to create a large-scale table-top display with pen-based interaction. Early experiments centered around using the setup to interact with Grasshopper definitions in groups. This work eventually led to a hybrid touch/pen interaction with the Microsoft Kinect (see the Grasshopper-Kinect project).
A Collaboration with Scott Crawford.
Design Machine Group, 2007
An Augmented Reality based system for reviewing Building Information Models using a tangible interface and a MagicLens. A single or multi-user tangible workplane is used to swap in and out different models which are sorted by layer. A modified presenter tool was augmented with a MagicLens-style filter tool, allowing the user to selectively toggle system visibility, effectively creating X-Ray views of the model.
C#, Kinect SDK, Grasshopper
Oversaw the development of a Microsoft Kinect-based multi-touch interface for interacting with Grasshopper parametric definitions on a large-scale table-top display. The system allowed users to review and manipulate nodes in a visual programming language through simple touch gestures (see right). Voted into the Top 10 Kinect Hacks of 2011. LMNts, with Viswa Kumaragurubaran.
Flash, Actionscript
A Flash-based interface for viewing and analyzing three Urban Design options at three different time-scales with three different performance metrics. The interface is well-suited to quick apples-to-apples comparisons from temporal, qualitative and numerical perspectives. With the LMN Architects, Urban Design Department.
Interaction Design and adaptation of multi-touch gestures for Grasshopper definition manipulation. The Kinect depth sensor registered touch events (see left) which were then analyzed across frames to form gesture events that corresponded to standard Grasshopper events such as selecting and moving nodes, panning and zooming the canvas, connecting wires between nodes, etc. At LMNts with Viswa Kumaragurubaran.
ARToolworks, 2007
Created an Augmented Reality-based MagicBook of Leonardo DaVinci’s inventions. Using an “Opera Glasses” style binocular viewer (with button controls in the handle), readers of the “Codex Interactivus” could flip the pages and watch Da Vinci’s inventions come to life. Each page contained an interactive and animated 3D model of each invention. Facing pages were Da Vinci’s sketches and translated notes. Users could manipulate each invention using buttons embedded in the Opera-Glasses-style wand.

Advocated for and managed burgeoning use of physical computing devices such as Arduino microcontrollers, sensors, and actuators, in an architectural professional practice for design conceptualization and scale modeling. Basic electronics skills: soldering, circuit testing, breadboarding, etc. were taught and promoted as part of LMN Tech Studio.
Processing, Arduino, Grasshopper, Firefly
Used a combination of physical-computing and parametrics to create lighting mock-ups and interaction with physical architectural models for design visualization. The Arduino micro-controllers were used to control arrays of mini-LED lights that were built into a series of architectural models (Tobin Center for the performing arts shown here). The LED lighting setups were controlled from a Grasshopper interface, allowing design teams to quickly determine lighting placement, color and intensity in scale models of theaters.

New Orleans Convention Center Design
LMN Architects
Increased use of Arduino, Processing, Firefly and Grasshopper within physical models at LMN became standard practice. In the case of the New Orleans Convention Center Ballroom design, the team included interior designers, lighting designers, facility operations staff and other stakeholders. The entire team used a scale model with built-in interactive LED lighting to experiment with different options. The model was then photographed to create compelling visualizations (see image at right)….

Final visualizations of the ballroom spaces were created using a combination of physical scale models with built-in mini-LED lighting, photography, and Photoshop compositing and post-processing. In this image, only the dining convention attendees and the screens in the distance are stock footage; the rest is a photograph of the physical model.
