This presents an opportunity for an enormous and unprecedented stimulation of creativity and production of knowledge.<br /> <br /> New licensing models have been created to help this collaborative creation. Open licenses such as Creative Commons provide ways for creators and distributors to work together. Such collaboration has proven itself fruitful also economically: open licensing has been succesfully used by music businesses, movie producers, book publishers and media companies.<br /> <br /> How is business created around open licensing? What benefits does the Creative Commons model provide for public broadcasting and archiving? How open licensing changes the production of cultural works? How does the common Nordic legal environment affect re-use of cultural works?<br /> <br /> Nordic Cultural Commons Conference provides insight into these questions. Bringing together all Nordic Creative Commons scholars and practitioners, it is also a great opportunity to meet and discuss the latest open content practices and ideas.<br /> <br /> Our speakers include Mike Linksvayer (Creative Commons), John Buckman (Magnatune), Nicklas Lundblad (Google) and Paul Gerhardt (BBC Creative Archive).<br /> <br /> Visit conference web site for more information: <a href="/nccc/">www.hiit.fi/nccc/</a></p></div></div></div><div class="field field-name-taxonomy-vocabulary-5 field-type-taxonomy-term-reference field-label-above"><div class="field-label">Events:&nbsp;</div><div class="field-items"><div class="field-item even"><a href="/events/2008">Events 2008</a></div></div></div> Thu, 23 Oct 2008 15:05:23 +0000 noronen 691 at http://old.hiit.fi http://old.hiit.fi/node/695 <div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><abbr class="dtstart" title="2008-09-08T06:45:00Z">ma 08.09. klo 09.45</abbr> <abbr class="dtend" title="2008-09-08T14:30:00Z"> - klo 17.30</abbr></p> <div class="loc">Paikka: <span class="location"><span class="adr"><span class="text">Dipolin auditorio</span>, <span class="street-address">Otakaari 24</span>, <span class="postal-code">02150</span>, <span class="locality">Espoo</span>, <span class="region">Finland</span>, <span class="country-name">FI</span></span> <span class="geo" style="display: none;"> <abbr class="latitude" title="60.1849">60&deg; 11,094 N</abbr> <abbr class="longitude" title="24.8317">24&deg; 49,902 E</abbr> </span> </span></div> <p>Rajaton tietojenk&auml;sittelytiede -tapahtuma j&auml;rjestet&auml;&auml;n Dipolin auditoriossa 8.9.2008 kello 9.45-17.30.

In my group the Future Applications Lab, we have tried to balance the search for new ideas, or the generation of inventions, with the need for grounding them in the real world through inquiry into human practices. With grounded innovation, we mean processes that balance the two axes of inquiry and innovation, to increase the chance for true innovations to be created. We have used this approach to develop a number of new applications and digital artifacts. For instance, the Context Camera is a novel digital camera that takes pictures where the visual appearance are affected by the surrounding sound and movement. GlowBots are small autonomous robotic pets that encourage long-term explorative interaction. In both these cases, the designs were driven by a combination of technical and conceptual invention. At the same time they were grounded in inquiry into unusual user groups, including amateur photographers who enjoy the unpredictable results of a slightly defect camera model, or owners of exotic pets such as snakes and spiders. We believe that grounded innovation can be a fruitful approach to create new applications that are novel and exciting while at the same time relevant and interesting for real users.<br /> <br /> <a href="http://www.viktoria.se/~leh/">Dr. Lars Erik Holmquist</a> is a senior researcher at the Swedish Institute of Computer Science in Kista, Sweden, a research leader in the Mobile Life Center at Stockholm University, and leader of the Future Applications Lab at the Viktoria Institute in G&ouml;teborg, Sweden.

He received his master&rsquo;s degree in Computer Science in 1996 and his Ph.D. in Informatics in 2000, both at the G&ouml;teborg University, and became an associate professor at the G&ouml;teborg IT University in 2004. His research interests include human-computer interaction, information visualization and ubiquitous computing. He has been member of many international conference committees and published extensively in these research fields. He was chair of the UbiComp 2002 conference and started the <em>Mobile Music Technology</em> workshop series in 2005.

The goal is to examine how the gaming experience - player's emotions and cognitions - can be accurately assessed.</p> <p>The project also develops a prototype of an emotionally adaptive game. The game changes in real time based on the player's emotional state. For example, the game can get more difficult if the player becomes nervous.</p> <p>The FUGA mini-symposium will be held at the <a href="/">Helsinki Institute for Information Technology (HIIT)</a> in Espoo on 24 April, 2008 from 13:00 to 17:00. At the symposium, the FUGA researchers from different European countries will present their latest findings.</p> <p>They will show new innovative techniques for researching the gaming experience. They will also provide new tools for designing games for different purposes.

Title and abstract follow.<br /> <h2>Multimedia Workloads, Architectures to Process Them, Their Performance and the Use of Caches for Multimedia Workloads </h2> Alan Jay Smith<br /> CS Division<br /> UC Berkeley<br /> Berkeley, California<br /> http://www.eecs.berkeley.edu/~smith<br /> <br /> Monday, Jan 7th 2008, 1:30 pm - 4 pm<br /> HIIT, Spektri Pilotti, 3rd floor, Mets&auml;nneidonkuja 4, Espoo<br /> <br /> The last decade has seen the integration of audio, video, and 3D graphics into existing workloads as well as the emergence of new workloads dominated by the processing of these forms of media. Unfortunately, widely accepted benchmarks which capture these new workloads in a realistic way have not emerged. We present the Berkeley multimedia workload, which was developed to facilitate our own studies on architectural support for multimedia.<br /> <br /> The caching behavior of multimedia applications has been described as having high instruction reference locality within small loops, very large working sets, and poor data cache performance due to non-locality of data references. Despite this, there is no published research deriving or measuring these qualities. Utilizing the previously developed Berkeley Multimedia Workload, we present the results of execution driven cache simulations with the goal of aiding future media processing architecture design. Our analysis examines the differences between multimedia and traditional applications in cache behavior.&nbsp; We find that multimedia applications actually exhibit lower instruction miss ratios and comparable data miss ratios when contrasted with other widely studied workloads.&nbsp; In addition, we find that longer data cache line sizes than are currently used would benefit multimedia processing.<br /> <br /> Many microprocessor instruction sets include instructions for accelerating multimedia applications such as DVD playback, speech recognition and 3D graphics.&nbsp; Despite general agreement on the need to support this emerging workload, there are considerable differences between the instruction sets that have been designed to do so.&nbsp; We present a study of the performance of five instruction sets on kernels extracted from a broad multimedia workload. Each kernel was recoded in the assembly language of the five multimedia extensions.&nbsp; We compare the performance of each extension against other architectures as well as to the original compiled C performance. From our analysis we determine how well multimedia workloads map to current architectures, what was useful and what was not. We also propose two enhancements to current architectures: strided memory operations, and superwide registers.<br /> <br /> The work to be presented was done with Nathan Slingerland, formerly a graduate student at UC Berkeley.</div></div></div><div class="field field-name-taxonomy-vocabulary-5 field-type-taxonomy-term-reference field-label-above"><div class="field-label">Events:&nbsp;</div><div class="field-items"><div class="field-item even"><a href="/events/2008">Events 2008</a></div></div></div> Mon, 07 Jan 2008 11:30:00 +0000 mam 444 at http://old.hiit.fi
