Studies have shown positive impact of video blogs (vlogs) on patient education. However, we know little on how patient-initiated vlogs shape the relationships among vloggers and viewers. We qualitatively analyzed 72 vlogs on YouTube by users diagnosed with HIV, diabetes, or cancer and 1,274 comments posted to the vlogs to understand viewers’(More)

Health video blogs (vlogs) allow individuals with chronic illnesses to share their stories, experiences, and knowledge with the general public. Furthermore, health vlogs help in creating a connection between the vlogger and the viewers. In this work, we present a qualitative study examining the various methods that health vloggers use to establish a(More)
Using peer-to-Peer (P2P) architectures for large scale <i>interactive</i> applications such as Massively Multiplayer Online Games (MMOG) is very challenging because of the difficulties to maintain a consistent game world in a distributed topology and exchange game state information in the P2P network without a central sever. In this demo proposal we present(More)
Educational tools that utilize the Internet to reach off-campus students are becoming more popular and many educational institutions are exploring their use. We report on a multiuser audio chat system that is using a multicast peer topology and is based on a new audio streaming protocol called YimaCast. The tool is designed to foster collaboration and(More)
The electrophysiological integrity of the adult rat spinal cord was assessed at the lumbar, lower cervical and cortical levels after the animals sustained a severe contusion injury at the mid-thoracic level (T8) and received either carbon filament cultured with fetal spinal cord tissue implants, fetal tissue implants, or carbon filament implants alone.(More)
In this paper, we describe a course of research investigating the potential for new types of music made possible by location tracking and wireless technologies. Listeners walk around downtown Culver City, California and explore a new type of musical album by mixing together songs and stories based on their movement. By using mobile devices as an interface,(More)
Peer-to-peer (P2P) streaming is emerging as a viable communications paradigm. Recent research has focused on building efficient and optimal overlay multicast trees at the application level. A few commercial products are being implemented to provide voice services through P2P streaming platforms. However, even though many P2P protocols from the research(More)
Children diagnosed with a chronic illness, such as cancer, experience a vastly different childhood than their healthy counterparts. They may struggle with accepting that they are no longer seen as "normal". We surveyed 10 children who have a chronic illness and interviewed 15 healthcare professionals and 7 parents of chronically ill children to understand(More)
