Abstract: In this study we compare human and machine acceptability judgments for extreme variations in sign productions. We gathered acceptability judgments of 26 signers and scores of three different Automatic Gesture Recognition (AGR) algorithms that could potentially be used for automatic acceptability judgments, in which case the correlation between human ratings and AGR scores may serve as an ‘acceptability performance’ measure. We found high human-human correlations, high AGR-AGR correlations, but low human-AGR correlations. Furthermore, in a comparison between acceptability and classification performance of the different AGR methods, classification performance was found to be an unreliable predictor of acceptability performance.

Me at the FG2008
I would almost forget, but I also presented some work at the FG2008 conference: Acceptability Ratings by Humans and Automatic Gesture Recognition for Variations in Sign Productions.
Snapshots of the three signs used in the experiment.
Examples of three manipulations of the sign SAW. We tested about 68 sign manipulations in total. These were run through the automatic recognition algorithms we had been working on and they were rated by human signers. The paper is about how humans and machines can be compared.
Nadia Magnenat-Thalmann at the FG2008
One of the more interesting lectures at the FG2008 conference was a keynote speech delivered by Nadia Magnenat-Thalmann, director of the MIRALab in Geneva. She talked about Communicating with a Virtual Human or a Robot that has Emotions, Memory and Personality. She went far beyond the simplistic notion of expressing 'the six basic emotions' and talked about how mood, personality and relationships may affect our facial expressions.
The talk by Magnenat-Thalmann focused on facial expression. (source)
By coincidence I got an invitation to write a paper for another conference, organized by Anton Nijholt and Nadia Magnenat-Thalmann (and others), called the Conference on Computer Animation and Social Agents (CASA 2009). It is organized by people from the University of Twente but held in Amsterdam. Call for papers: deadline February 2009.
Nadia also mentioned a researcher at Utrecht University called Arjan Egges. He got his PhD at the MIRALab and is now working on "the integration of motion capture animation with navigation and object manipulation".

ERC grant Onno Crasborn
Onno got a grant from the European Union that will allow him to start his own research group. He will investigate what happens 'on the other hand' in signed languages.
