3D Object Classification via Spherical Projections

Zhangjie Cao, Qixing Huang, Karthik Ramani
In Proceedings of International Conference on 3D Vision (3DV 2017), Spotlight Presentation. Qingdao, China, October 12-14, 2017

In this paper, we introduce a new method for classifying 3D objects. Our main idea is to project a 3D object onto a spherical domain centered around its barycenter and develop neural network to classify the spherical projection. We introduce two...

In Proceedings of the 30th Annual ACM Symposium on User Interface Software & Technology (UIST'17) , Quebec City, Canada, 2017 (Acceptance Rate: 22.5%)

We present iSoft, a single volume soft sensor capable of sensing real-time continuous contact and unidirectional stretching. We propose a low-cost and an easy way to fabricate such piezoresistive elastomer-based soft sensors for instant...

Robust Hand Pose Estimation during the Interaction with an Unknown Object

Robust Hand Pose Estimation during the Interaction with an Unknown Object

Chiho Choi, Sang Ho Yoon, Chin-Ning Chen, Karthik Ramani
Proceedings of the IEEE International Conference on Computer Vision, 3123-3132

Abstract: This paper proposes a robust solution for accurate 3D hand pose estimation in the presence of an external object interacting with hands. Our main insight is that the shape of an object causes a configuration of the hand in the form of a...

Learning Hand Articulations by Hallucinating Heat Distribution

Learning Hand Articulations by Hallucinating Heat Distribution

Chiho Choi, Sangpil Kim, Karthik Ramani
Proceedings of the IEEE International Conference on Computer Vision, 3104-3113

We propose a robust hand pose estimation method by learning hand articulations from depth features and auxiliary modality features. As an additional modality to depth data, we present a function of geometric properties on the surface of the hand...

Design Patterns for Visualization-Based Tools in Sustainable Product Design

Design Patterns for Visualization-Based Tools in Sustainable Product Design

Ramanujan D., Bernstein W.Z., Ramani K.
Proceedings of the 2017 ASME International Design Engineering Technical Conferences, Cleveland, Ohio, USA

Most design activities involve exploring and comparing existing designs. Thus, adopting an eco-conscious approach in the design exploration process can aid environmentally sustainable product design (SPD). One approach for supporting exploration in...

The Design for Additive Manufacturing Worksheet

The Design for Additive Manufacturing Worksheet

Joran W. Booth, Jeffrey Alperovich, Pratik Chawla, Jiayan Ma, Tahira Reid, Karthik Ramani
Journal of Mechanical Design 139.10 (2017): 100904.

Additive manufacturing (AM) technologies have become integral to modern prototyping and manufacturing. Therefore, guidelines for using AM are necessary to help users new to the technology. Many others have proposed useful guidelines, but these are...

Secure Collaboration in Engineering Systems Design

Secure Collaboration in Engineering Systems Design

Wang S., Bhandari S., Chaduvula S. Chaitanya, Atallah M., Panchal J. H., Ramani K
Journal of Computing and Information Science in Engineering 17.4 (2017): 041010.

The goal in this paper is to enable collaboration in the co-design of engineering artifacts when participants are reluctant to share their design-related confidential and proprietary information with other co-designers, even though such information...

Integrating Visual Analytics Support for Grounded Theory Practice in Qualitative Text Analysis

Integrating Visual Analytics Support for Grounded Theory Practice in Qualitative Text Analysis

Senthil Chandrasegaran, Sriram Karthik Badam, Lorraine Kisselburgh, Karthik Ramani, Niklas Elmqvist
Computer Graphics Forum. Vol. 36. No. 3. 2017.

We present an argument for using visual analytics to aid Grounded Theory methodologies in qualitative data analysis. Grounded theory methods involve the inductive analysis of data to generate novel insights and theoretical constructs. Making sense...
