Communication Behavior in Embodied Virtual Reality

Human Computer Interaction Conference (CHI)

To investigate communication behavior with embodied virtual reality onto an avatar in a virtual 3D environment, we had 30 dyads complete two tasks using a shared visual workspace: negotiating an apartment layout and placing model furniture on an apartment floor plan.

Examining the Demand for Spam: Who Clicks?

Conference on Human Factors in Computing Systems (CHI)

Some spam content manages to evade detection and engage users which is why, in this paper, we focus on the demand side of the spam equation examining what drives users to click on spam via a largescale analysis of de-identified, aggregated Facebook log data (n=600,000).

A Face Recognition Application for People with Visual Impairments: Understanding Use Beyond the Lab

Conference on Human Factors in Computing Systems (CHI)

We present Accessibility Bot, a research prototype bot on Facebook Messenger, which leverages state-of-the-art computer vision algorithms and the existing set of tagged photos of a user’s friends on Facebook to help people with visually impairments recognize their friends.

Rethinking Concurrency Control for In-Memory OLAP DBMSs

IEEE International Conference on Data Engineering (ICDE)

In this paper we describe a new concurrency control protocol specifically designed for analytical DBMSs that can provide Snapshot Isolation for distributed in-memory OLAP database systems, called Append-Only Snapshot Isolation (AOSI).

Sparse Head-Related Transfer Function Representation with Spatial Aliasing Cancellation

International Conference on Acoustics, Speech and Signal Processing

In this paper, a new technique to reconstruct high resolution individual HRTFs from sparse measurements is presented. This is achieved by minimizing the spatial aliasing error in the spherical harmonics (SH) representation of the HRTFs, and by incorporating statistics calculated from a set of reference HRTFs, leading to an optimal minimum mean-square error solution.
