Understanding Brainstorming through Text Visualization

by Senthil | Jul 29, 2013 | 2013, DESIGN METHOD, Design Representation, Karthik Ramani, Publications, Senthil Chandrasegaran

Automated content analysis software tools have significantly aided in the study of design processes in the recent past. However, they suffer from the lack of domain knowledge and insight that a human expert can provide. In this paper, we adopt the use of text...

Multiscale Kernels using Random Walks

by ayan | Jul 10, 2013 | 2013, Ayan Sinha, HUMAN SHAPE INTERACTION, Karthik Ramani, People, Publications, Shape Understanding

ABSTRACT We introduce novel multiscale kernels using the random walk framework and derive corresponding embeddings and pairwise distances. The fractional moments of the rate of continuous time random walk (equivalently diffusion rate) are used to discover higher order...

Shape-It-Up: Hand Gesture Based Creative Expression of 3D Shapes Using Intelligent Generalized Cylinders

by Convergence Design Lab Admin | May 10, 2013 | 2013, HUMAN SHAPE INTERACTION, Karthik Ramani, Mid-air Interaction, People, Publications, Vinayak

Abstract: We present a novel interaction system, “Shape-It-Up”, for creative expression of 3D shapes through the naturalistic integration of human hand gestures with a modeling scheme dubbed intelligent generalized cylinders (IGC). To achieve this...

Extended Multitouch: Recovering Touch Posture & Identity Using Depth Cameras on a Pen+Touch Tabletop Interface

by Convergence Design Lab Admin | Oct 3, 2012 | 2012, HUMAN SHAPE INTERACTION, Karthik Ramani, Mid-air Interaction, Multi-touch Interaction, Publications, Vinayak

Abstract: Multitouch surfaces are becoming prevalent, but most existing technologies are only capable of detecting the user’s actual points of contact on the surface and not the identity, posture, and handedness of the user. In this paper, we define the concept...
