GestureAnalyzer: Visual Analytics for Pattern Analysis of Mid-Air Hand Gestures

Sujin Jang, Niklas Elmqvist, Karthik Ramani
Proceedings of the ACM Symposium on Spatial User Interaction, October 4-5, 2014, Honolulu, HI, USA

Understanding the intent behind human gestures is a critical problem in the design of gestural interactions. A common method to observe and understand how users express gestures is to use elicitation studies. However, these studies requires...

Plex: Finger-Worn Textile Sensor for Mobile Interaction during Activities

Sang Ho Yoon, Ke Huo, Karthik Ramani
In Proceedings of the International Joint Conference on Pervasive and Ubiquitous Computing: Adjunct Publication (Ubicomp'14 Adjunct), Seattle, USA, 2014.

Abstract: We present Plex, a finger-worn textile sensor for eyes-free mobile interaction during daily activities. Although existing products like a data glove possess multiple sensing capabilities, they are not designed for environments where body...

BendID: Flexible Interface for Localized Deformation Recognition

BendID: Flexible Interface for Localized Deformation Recognition

Vinh Nguyen, Sang Ho Yoon, Ansh Verma, Karthik Ramani
Proceedings of the ACM international Joint Conference on Pervasive and Ubiquitous Computing, Sep 13-17, Seattle, USA. pp 553-557, 2014

We present BendID, a bendable input device that recognizes the location, magnitude and direction of its deformation. We use BendID to provide users with a tactile metaphor for pressure based input. The device is constructed by layering an array of...

Art Meets Engineering Design: An Approach for Reducing Sketch Inhibition in Engineers During the Design Process

Art Meets Engineering Design: An Approach for Reducing Sketch Inhibition in Engineers During the Design Process

Joran W. Booth, Abhinav K. Bhasin, and Karthik Ramani
In ASME 2014 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference (pp. V003T04A013-V003T04A013). American Society of Mechanical Engineers.

While much prior work has been done regarding sketching and its impact on design and a few on how to train engineers to sketch, there have been no prior studies in engineering to reduce inhibition to frequent sketching. This paper describes a...

PROTO-TAI: Quick Design Prototyping using Tangible Assisted Interfaces

Cecil Piya, Karthik Ramani
Proceedings of the ASME 2014 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference IDETC/CIE 2014, August 16-20, 2014, Buffalo, NY, USA

In the real world, we use our innate manual dexterity to create and manipulate 3D objects. Conventional virtual design tools largely neglect this skill by imposing non-intuitive 2D control mechanisms for interacting with 3D design models. Their...
