Our paper titled "A hidden Markov model-based acoustic cicada detector for crowdsourced smartphone biodiversity monitoring" received the award for Outstanding Student Paper at the International Joint Conference for Artificial Intelligence (IJCAI), 2013. The conference was held in Beijing, China, and the paper was presented by Davide Zilli.

Abstract: Automated acoustic recognition of species aims to provide a cost-effective method for biodiversity monitoring. This is particularly appealing for detecting endangered animals with a distinctive call, such as the New Forest cicada. To this end, we pursue a crowdsourcing approach, whereby the millions of visitors to the New Forest will help to monitor the presence of this cicada by means of a smartphone app that can detect its mating call. However, current systems for acoustic insect classification are aimed at batch processing and not suited to a real-time approach as required by this system, because they are too computationally expensive and not robust to environmental noise. To address this short-coming we propose a novel insect detection algorithm based on a hidden Markov model to which we feed as a single feature vector the ratio of two key frequencies extracted through the Goertzel algorithm. Our results show that this novel approach, compared to the state of the art for batch insect classification, is much more robust to noise while also reducing the computational cost.

Alex Wood being awarded the Best Presentation prize
Our presentation entitled "DejaView: help with memory, when you need it" was awarded the best presentation prize at the SenseCam 2012 Symposium. The prize was awarded by Steve Hodges from Microsoft Research. Abstract: Promising findings in the use of wearable memory aids such as SenseCam have been widely reported. However, to date, there has been relatively little consideration of the potential for offering memory help in real-time during daily living. Such assistance, in the form of proactiv... [more]

Haptics Demoed at SoNG Outreach Event
18th November 2010
The Southampton Neuroscience Group (SoNG)
Our interdisciplinary research on haptic devices for tactile interaction was showcased at this year's SoNG 'Outreach' event'. The Outreach event was held to showcase research to both the University and selected school teachers, charities, patient groups and industrialists. At the event, we demonstrated some of the wearable tactile devices that we have produced through the project, and reported on the findings of their evaluation on human participants. The Southampton Neuroscience Group (So... [more]
