| Get what you want, faster, through content-centric networks! Video - Jim Thornton, PARC Posted: 26 Sep 2010 07:22 PM PDT Get what you want faster: Xerox PARC has a plan to make the internet more speedy Dean Takahashi, VentureBeat, 9/26/10 In the video below, Jim Thornton, a researcher at PARC, is interviewed by Dean Takahashi, from VentureBeat. Jim discusses his work in the area of content-centric networking, also known as CCN or Named-Data-Networking (NDN). CCN is a way to work around the problem of internet "bottlenecking", something that happens when lots of people want to view rich multimedia content at the very same time. As it stands, content-delivery companies handle this problem by storing content in video caches, identified by IP addresses. If you search for content via the CCN protocol, your search will lead to a memory node that is identified by the name of the content (or other information that identifies the content), rather than an IP address, and select the content that is closest to your location. One of the objectives of CCN is to reduce internet bandwidth expenses. PARC is working with nine universities on this project, which provides open-source software that can be found on the Project CCNx website. About CCNx: "Project CCNx exists to develop, promote, and evaluate a new approach to communication architecture we call content-centric networking. We seek to carry out this mission by creating and publishing open protocol specifications and an open source software reference implementation of those protocols. We provide support for a community of people interested in experimentation, research, and building applications with this technology, all contributing to its evolution." If you are curious, the open-source Content Centric Networking code can be found on the github website. If you visit the website, make sure you take a look at the "ReadMe" section. Also heed this warning, found on the Project CCNx website: "CCNx technology is still at a very early stage of development, with pure infrastructure and no applications, best suited to researchers and adventurous network engineers or software developers. If you're looking for cool applications ready to download and use, you are a little too early."

Proceedings of the 5th ACM International Conference on Emerging Networking Experiments and Technologies (CoNEXT 2009); 2009 December 1-4; Rome, Italy. NY: ACM; 2009; 1-12. "Network use has evolved to be dominated by content distribution and retrieval, while networking technology still can only speak of connections between hosts. Accessing content and services requires mapping from the what that users care about to the network's where. We present Content-Centric Networking (CCN) which takes content as a primitive – decoupling location from identity, security and access, and retrieving content by name. Using new approaches to routing named content, derived heavily from IP, we can simultaneously achieve scalability, security and performance. We have implemented the basic features of our architecture and demonstrate resilience and performance with secure file downloads and VoIP calls." SocialTV: designing for distributed, social television viewing (pdf) Ducheneaut, N. ; Moore, R. J. ; Oehlberg, L.; Thornton, J. D. ; Nickell, E. SocialTV: designing for distributed, social television viewing. International Journal of Human-Computer Interaction. 2008 February; 24 (2): 136-154. "Media research has shown that people enjoy watching television as a part of socializing in groups. However, many constraints in daily life limit the opportunities for doing so. The Social TV project builds on the increasing integration of television and computer technology to support sociable, computer-mediated group viewing experiences. In this paper, we describe the initial results from a series of studies illustrating how people interact in front of a television set. Based on these results, we propose guidelines as well as specific features to inform the design of future "social television" prototypes." http://interactivemultimediatechnology.blogspot.com  |
| Posted: 26 Sep 2010 08:21 PM PDT I came across a link about Dan Saffer's recent post, Essential Interaction Design Essays and Articles. Equally important is Dan Saffer's List: Top Ten Essential Interaction Design Books. Dan Saffer is one of my "important influences". When I was taking HCI and Ubiquitous Computing courses, I bought the first edition of his book, Designing for Interaction: Creating Innovative Applications and Devices. In today's world of technical convergence, it is an important read, as Saffer's content crosses a number of disciplines.  It doesn't surprise me to learn that the #1 book on Saffer's Essential Interaction Design Books list is list is Don Norman's The Design of Everyday Things  . According to Saffer, "there's no getting around it: this is the book. Affordances, mental models, and other bits that have all become part of the general lexicon all started with The Don's book. A must read."  Don Norman's book was required reading in the Human-Computer Interaction class I took a few years ago. As I read through the book, I sensed a familiar tone. I later learned that Don Norman was the co-author of a required textbook for one of the psychology courses I took when I was a university student the first time around.  Don Norman's thinking has influenced me for decades - he continues to be an influence, because he writes articles for one of my favorite publications, Interactions Magazine:  It brightens up my day when I open up my mailbox- the one at the end of my real-life driveway- and find my Interactions magazine, in all of its well-designed, well-written, semi-glossy-paged glory, waiting for me to open up and read. The September/October, 2010 issue includes articles on topics related to authenticity in new media, the complexity of "advancement", design and usability, and the politics of development. A must-read is Gestural Interfaces: A Step Backwards in Usability, co-authored by Don Norman and his collaborator, Jakob Neilson, Here is an excerpt from the article, which highlights some of the problems of rushing to get products with natural-user interfaces out to market: "Why are we having trouble? Several reasons:
