IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS'14) , Chicago, September, 2014

Origami affords the creation of diverse 3D objects through explicit folding processes from 2D sheets of material. Originally as a paper craft from 17th century AD, origami designs reveal the rudimentary characteristics of sheet folding: it is...

ChiroBot: Modular-Robotic Manipulation via Spatial Hand Gestures.

ChiroBot: Modular-Robotic Manipulation via Spatial Hand Gestures.

Jasjeet Singh Seehra, Ansh Verma and Karthik Ramani
Proceedings of the 2014 conference on Interaction design and children (IDC '14). ACM, New York, NY, USA, 209-212.

We introduce ChiroBot, a cyber-physical construction kit that allows users to create custom robots out of craft material, easily assemble the robots using joint modules and control them using hand gestures. These hand-crafted robots are assembled...

IDEA-Pen: Interactive Design and Analysis through a Pen-based Interface

IDEA-Pen: Interactive Design and Analysis through a Pen-based Interface

Anirudh Roshan Sriram, Monica E Cardella, Karthik Ramani
121st ASEE Annual Conference & Exposition, Indianapolis, IN, June 15-18, 2014

For students to succeed in engineering design (and engineering practice) they must be able to make design decisions that are grounded in data and analysis. The potential danger, however, in introducing analysis and calculations too early in the...

PuppetX: A Framework for Gestural Interactions With User Constructed Playthings

Saikat Gupta, Sujin Jang, and Karthik Ramani
Proceedings of the ACM Conference on Advanced Visual Interfaces, May 27-30, Como, Italy. pp. 73-80, 2014

We present PuppetX, a framework for both constructing playthings and playing with them using spatial body and hand gestures. This framework allows users to construct various playthings similar to puppets with modular components representing basic...

Tracing and Sketching Performance using Blunt-tipped Styli on Direct-Touch Tablets

Tracing and Sketching Performance using Blunt-tipped Styli on Direct-Touch Tablets

Sriram Karthik Badam, Senthil Chandrasegaran,Niklas Elmqvist, and Karthik Ramani
Proceedings of the ACM Conference on Advanced Visual Interfaces, May 27-30, Como, Italy. pp. 193-200, 2014

Direct-touch tablets are quickly replacing traditional pen-and-paper tools in many applications, but not in case of the designer's sketchbook. In this paper, we explore the tradeoffs inherent in replacing such paper sketchbooks with digital tablets...

zPots : A Virtual Pottery Experience Through Spatial Interactions Using the Leap Motion Device

zPots : A Virtual Pottery Experience Through Spatial Interactions Using the Leap Motion Device

Vinayak, Karthik Ramani, Kevin Lee Jr., Raja Jasti
Proceedings of the ACM CHI' 14 Extended Abstracts on Human Factors in Computing System (CHI EA'14) April 26- May 1, Toronto, Canada.

We present zPots, an application for gesture-free hand-based design of virtual pottery enabled by the Leap Motion device. With zPots, a user can shape and color 3D pots by moving bare hands in the air with minimal or no training. Unlike large-space...

Chiron: Interpreting signals from Capacitive Patterns and Inertial Sensors for intuitive Shape Modeling.

Ansh Verma, Gabriel Culberston and Karthik Ramani
In Proceedings of the extended abstracts of the 32nd annual ACM conference on Human factors in computing systems (pp. 1831-1836). ACM.

In this paper we introduce Chiron (abbr. Chironomia ): A wearable device for the hand that reads the digital and analogous signals from capacitive sensor patterns and orientation sensors, to interpret user-intent. Here, we explore two cases -- (a)...

Juxtapoze: Supporting Serendipity and Creative Expression in Clipart Compositions

Juxtapoze: Supporting Serendipity and Creative Expression in Clipart Compositions

William Benjamin, Senthil Chandrasegaran, Devarajan Ramanujan, Niklas Elmqvist, SVN Vishwanathan, Karthik Ramani
Proceedings of the ACM Conference on Human Factors in Computing Systems, April 26 - May 1, Toronto, Canada. pp 341-350, 2014.

Juxtapoze is a clipart composition workflow that supports creative expression and serendipitous discoveries in the shape domain. We achieve creative expression by supporting a workflow of searching, editing, and composing: the user queries the...
