Paper points to new ways to verify visualizations

Errors in visualizations used to verify large-scale data analysis are often the result of the limitations of underlying visualization algorithms and techniques. These errors can be hard to find.

In this paper presented at InfoViz in October, Carlos Scheidegger and co-authors propose using topological properties as a more robust verification technique.

Geocast: A technology for when disaster strikes

Disasters often knock out power and communications, making it difficult for rescue personnel to communicate with one another or to locate survivors.

This MSNBC video (at 4:03) shows how Geocast, an ad hoc network protocol, can enable smart phones to communicate even in the absence of cell towers and other fixed infrastructure.

Study looks at speaking rates and TTS intelligibility

AT&T researchers, along with the ASA Text-to-Speech (TTS) Technology working group (S3-WG91), are collecting data comparing the intelligibility of seven different synthetic speech systems at various speaking rates. The aim is to make TTS more usable by all, including users of mobile devices, children with learning disabilities, people with visual disabilities (see paper) or hearing impairments.
