Talk Title: The Spoken Web
Abstract: The Spoken Web is a system that leverages the pervasiveness of mobile phones in developing countries and allows the creation, deployment, and hosting of voice-driven applications called VoiceSites by any phone subscriber. It attempts to empower users by giving them the opportunity to become content creators and provides a mechanism for users to access information and content with affordable devices (just a regular telephone). Being a voice-driven system, it extends the access to ICTs (Information and Communication Technologies) to illiterate users. Many users in the developing world are now creating and accessing information through the Spoken Web platform. The content ranges from information about people and events in a village to information about the crop prices in the market, to business information for the unorganized workforce in developing regions. This session will start with the need for such a technology, then focus on the technology platform that drives the Spoken Web and will finally end with some interesting field insights that were derived as a result of it being used by low-literate users for a period of more than three years.
Biography: Amit is a Senior Researcher and barely manages Telecom Solutions Research at IBM Research, India. He has been working on Telecom social network analysis (SNAzzy) since its inception in 2006. He is also a âSpoken Webâ evangelist â trying to promote the vision of a world-wide Spoken Web hosted in the Telecom network, which does not require an Internet connection or the ability to read and write. He is always interested in applying graph theory to various domains. He also dabbles with speech in mobile and pervasive environments. Along with Nitendra, he has been co-hosting the SiMPE workshop for the last 7 years at the ACM MobileHCI conference. Together they wrote a book on âSpeech in Mobile and Pervasive Environmentsâ published by Wiley in 2012. Much to his surprise and that of his friends, he was named a Master Inventor at IBM Research in 2011.

Medical Imaging Seminar Series
Tue, Sep 25, 2012 @ 01:45 PM - 03:00 PM

Speaker: Dr. Shuliang Jiao, Department of Ophthalmology and Department of Biomedical Engineering, University of Southern California
Talk Title: "Multi-modal Retinal Imaging: Technology Development"
Abstract: Photoacoustic ophthalmoscopy (PAOM) is a new retinal imaging technology based on the photoacoustic effect. PAOM detects the ultrasonic waves induced by pulsed laser light shined onto the retina. PAOM offers the unique capability to measure optical absorption contrast in the retina, which is suitable for imaging retinal vessel oxygenation and the pigmentation of the RPE cells. Since PAOM is compatible with optical coherence tomography, scanning laser ophthalmoscopy, and autofluorescence imaging, registered multimodal images can be acquired from a single device at comparable resolution for comprehensive anatomic and functional retinal characterizations. Therefore, photoacoustic ophthalmoscopy is anticipated to have applications in both research and clinical diagnosis of many blinding diseases. This talk will cover the principles of PAOM, the integration of PAOM with OCT and auto-fluorescence for multimodal imaging, and the integration of adaptive optics in PAOM.
Biography: Shuliang Jiao, PhD, is an associate professor in the Department of Ophthalmology and the Department of Biomedical Engineering at University of Southern California. He received his PhD in Biomedical Engineering from Texas A&M University in 2003. His research interest is bio-optical imaging. His current research focus is optical coherence tomography (OCT) and photoacoustic microscopy with the emphasis of their applications in eye imaging. He is one of the pioneers in Mueller-matrix polarization-sensitive OCT, OCT small animal ocular imaging, and photoacoustic retinal imaging. He also holds four US patents and several US patent applications.
