Verkon digikuvat katoavat käyttäjiltä mutta säilyvät netissä

rsarvas — Wed, 23 Mar 2011 19:27:56 +0000

Ladatessaan verkkoon digivalokuviaan käyttäjä kohtaa kaksi keskeistä riskiä: Kuvat ja niihin liittyvät tiedot voivat kadota käyttäjältä ikuisiksi ajoiksi palveluntarjoajan toiminnan loppuessa. Toisaalta käyttäjän voi olla vaikea poistaa kuvia, kun ne on kerran verkossa julkaistu. Juuri ilmestyneessä kirjassaan "From snapshots to social media: the changing picture of domestic photography" (Valokuvauksesta sosiaaliseen mediaan: kotivalokuvaus muutoksessa) Risto Sarvas ja David M. Frohlich käsittelevät ajankohtaisia digivalokuvauksen riskejä.

− Viimeisen viiden vuoden ajalta on esimerkkejä siitä, kuinka valokuvien jakamista helpottavat verkkopalvelut ovat lopettaneet toimintansa ja samalla on kadonnut käyttäjien kuvia, videoita tai niihin liittyviä kommentteja. Esimerkiksi kuvapalvelu Ringo lopetti toimintansa vuonna 2008, eikä käyttäjillä ollut mahdollisuutta ottaa talteen kommenttejaan tai videoitaan, sanoo tutkijatohtori Risto Sarvas Aalto-yliopiston Tietotekniikan tutkimuslaitos HIIT:stä.

− Samaan aikaan käydään keskustelua verkon valokuvien yksityisyydestä ja ihmisten voimattomuudesta poistaa kerran internetissä julkaistuja kuviaan. Parhaimmillaan tai pahimmillaan digikuva alkaa elää verkossa omaa elämäänsä täysin kuvan omistajan ulottumattomissa, Sarvas jatkaa.

Taustalla on viime vuosikymmenien murros valokuvauksessa, jota on kiihdyttänyt kuvien digitalisoituminen, kamerakännykät ja internetin yleistyminen. Tänä päivänä valokuvien jakaminen, katselu, julkaisu ja arkistointi tapahtuvat kaikki usein kaupallisissa verkkopalveluissa, joiden elinkaari voi olla lyhyempi kuin valokuvien omistajat haluaisivat.

− Yrityksillä ja palveluilla on aina ollut merkittävä rooli kotivalokuvauksessa, mutta paperikuvien aikakaudella kuvien katsomiseen, jakamiseen tai arkistointiin ei vaadittu huipputeknologiaa eikä palveluita, tarkentaa kirjan toinen kirjoittaja professori David M. Frohlich Surreyn yliopistosta, Englannista.
− Jos haluamme digivalokuviemme säilyvän kymmenen tai viisikymmentä vuotta, on meidän luotettava siihen, että verkkopalvelut pysyvät hengissä tämän ajan tai että saamme pidettyä kuvatiedostomme, kovalevymme, romppumme ja tietokoneemme toimivina ja ajan tasalla.

Digikuvauksen alueella onkin selkeä tarve uusille ratkaisuille, joiden lähtökohtina ovat avoimet teknologiastandardit, luotettavuus sekä hajautettu ja pitkäaikainen digimateriaalin arkistointi.

Sarvas ja Frohlich kuvaavat kirjassaan, kuinka paperivalokuvista digikuviin siirryttäessä kotivalokuvaus on tullut asteittain riippuvaisemmaksi tieto- ja viestintäteknologian palveluista ja infrastruktuurista. Kotivalokuvaus on perinteisesti ollut tapa luoda yhteenkuuluvuutta, rakentaa omaa identiteettiä ja kerätä perheen kuvallista historiaa. Nyt näiden sosiaalisten tarpeiden toteuttaminen valokuvauksen avulla on tiivisti kytketty tietotekniikkaan.

Kirjan avoin julkaisuseminaari pidetään 30.3. klo 14 - 16 Suomen valokuvataiteen museolla, Kaapelitehtaalla, Helsingissä (www.hiit.fi/snapshots). Ilmoittautuminen 28.3. mennessä.

Welcome to a public seminar on the future of domestic digital photography. The seminar celebrates the publication of the book

From snapshot to social media: the changing picture of domestic photography (Springer 2011)

by Risto Sarvas and David M Frohlich. The book is pioneering work in combining the technically oriented computer science work on photography with more traditional studies of domestic photography. The book is also the first to chart a socio-technical history of domestic and snapshot photography from the invention of photography in 1839 to current and future trends in the 21st century.

In the seminar we will hear two keynote presentations. Elina Heikka will discuss domestic photography from the perspective of traditional photography, and Markus Huttunen will talk about digital media from the perspective of business strategies. Following these keynotes the two authors will present the central messages and points of the book. After these talks there is time reserved for a general discussion. The speakers and their affiliations are:

Elina Heikka, Director of the Finnish Museum of Photography
Markus Huttunen, Managing Director and Partner of Magenta Advisory Ltd
David M Frohlich, Director of Digital World Research Centre, University of Surrey, UK
Risto Sarvas, Research Scientist at the Helsinki Institute for Information Technology HIIT, Aalto University

Pervasive User Modeling and Personalization (PUMP'10)

ptnurmi — Thu, 14 Jan 2010 03:24:26 +0000

Workshop at UMAP'10, June 20, Big Island, HI

Mobile and pervasive computing technologies have become an integral part of everyday life and have changed the way people interact with information. The rapidly growing amount of information and services raises the need for user modeling and personalization in pervasive and ubiquitous environments. Unique challenges include (1) inferring relevant information about a user from sensors, (2) aggregating and integrating such information effectively into long-term user models, while achieving user model interoperability, and (3) providing pervasive and ubiquitous information access in a personalized manner. The objective of this workshop is to bring together active researchers and practitioners working on user modeling and personalization in pervasive and ubiquitous environments and to produce vision statements about the future of these fields.

Workshop Topics

The workshop addresses the following four focus questions:

What pervasive or situational information is most useful for user modeling and personalization, how can such information be extracted from sensors, and how can the information be represented and effectively used in user models?
How can we aggregate and integrate user modeling data from various sources, resolve conflicts, and abstract from and reason about the data?
How can we overcome syntactic and semantic heterogeneity of distributed user models in order to achieve user model interoperability?
What unique challenges and opportunities exist in pervasive ubiquitous environments that are not present in conventional online personalization domains, and how can these challenges be addressed?

A bibliometric exercise for SIGCHI Conference on Human Factors in Computing Systems. By Antti Oulasvirta. 2006

oulasvir — Fri, 09 Mar 2007 06:43:27 +0000

See a more recent bibliometric analysis by Christop Bartneck!

Today's academic research is a competitive enterprise, similar in many respects to sports. "Publish or perish" is no joke but hard reality for researchers who have to compete for funding, for publications, for fame. But can we measure their performance and, perhaps, see who "holds the world record"?

Ever since academic research ceased to be a hobby of the blue-blooded, there has been an interest in measuring scientific performance. There are numerous rankings and evaluations of scientific institutions and they play an important role, perhaps too important, in political decision-making. While the "validity" of quantifications of scientific output has been questioned, for good reasons, I still find them inspiring and at times even amusing. They certainly have their own role in this economy. However, to my disappointment, I have not been able to find systematic measurements of my own field, the field of human-computer interaction (HCI), quite likely because the field is so young. (See also this.) In the spirit of the science=athletics equation, I was interested to find out what is the "world record" there and who holds it? Who are the athletes and how good are they? If a new athlete enters this arena, what are his/her changes of success?

To satisfy my curiosity, I needed to produce some measurements, and I decided to start from a particular scientific conference, the CHI. The annual ACM Conference on Human Factors in Computing Systems, or CHI for short, if any event, corresponds to the 100 metres sprint in HCI. It is undoubtedly the most competitive conference with the broadest attendance. To "measure CHI", I made a small bot that crawled the ACM Digital Library on 6th March 2007, starting from the Proceedings of CHI 2006. My humble bot extracted the title, the first author, the number of citings (if any), and some other relevant pieces of information. The key measure of performance is thus here, in the absence of alternatives, the number of citings in the ACM Digital Library.

Before moving on, please take a minute to read a few words about the data set. First, the proceedings span years from 1990 to 2006, because when the bot was supposed to move from CHI'90 to CHI'89, the ACM server blacklisted my IP address for repeated downloads :( This does look like a DoS attack, after all. In addition, the server could not always respond to the queries; I calculated that some 20-30 individual publications, and the whole year of 1991 (!), and the full paper procs of 1992, are missing due to Server busy errors. Moreover, the Digital Library does not always report exact citings number if there are three or less citations, which means that there are more 0 citation papers in the data than in reality. Moreover, self-citations were not removed. Please take these shortcomings into account when interpreting the results. I intend to revise my code and complete the crawl if people find these statistics useful.

1. The most cited first authors 1990-2006

If the number of citings is the measure, the following people are the ten most successful people in the history of CHI since 1990. The list contains no surprises, all of these researchers have not only been researching a topic, but have been establishing important new areas of research.

Note: Some authors have used two or more different versions of his/her name and may therefore not show as high on the list as he/she should. William Gaver / Bill Gaver / William W. Gaver is a perfect example. I did not have time to go through the whole list of almost 3000 authors to fix this issue.

First author	Citings
Hiroshi Ishii	378
Upendra Shardanand	187
Peter Pirolli	174
Steve Whittaker	160
Jun Rekimoto	159
John Lamping	132
George W. Fitzmaurice	131
I. Scott MacKenzie	124
Sharon Oviatt	121
Steve Benford	116

If you're interested, you can find the list ALL first authors from here. 2781 authors altogether!

There's a Most frequent authors list available at Gary Perlman's HCI Bibliography. HCIBib's list is perhaps more comprehensive in the sense that it covers more publications and from a longer period of time. However, the list is not based on citings, but on the total number of publications. These differences explain why the two lists seem so distant.

2. The most influential sites of research

Jakob Nielsen evaluated in his Alertbox article that the best HCI labs in the 1990s were

Gold: Bell Communications Research (Bellcore)
Silver: Apple Computer Advanced Technology Group
Bronze: Xerox PARC

and in 2000-2010 are going to be

Gold: Microsoft Research
Silver: Xerox PARC
Bronze: Carnegie Mellon University.

According to my bot, the best sites in 1990-2006 have been:

Position	Site	Citings
1.	Xerox PARC	1133
2.	MIT Media Lab	849
3.	Microsoft Research	443
4.	CMU	361
6.	UC Berkeley	232

Thus, the "hard facts" disagree with Nielsen's opinions. Xerox is no doubt the most important site, particularly so in the 1990s. And MIT Media should be included as the "silver medalist".

Disclaimer: For the time being, these were calculated by merging the affiliations that referred to the same institute only in the list of the top 30 affiliations. By doing this I hoped to address the fact that the naming conventions and the names of the institutes have changed over the years. The list could look different if this was done properly. I am tempted to re-do this in the near future.

And an extract from the stats that might interest us Finns:

Helsinki University of Technology (incl. my institute HIIT) - 50 citations
Nokia Research Center - 32
University of Tampere - 18
University of Jyväskylä - 13
University of Helsinki - 2.*

* University of Oulu's CHI paper from 1993 also has 2 citings, but due to the limitations of the ACM DL and my bot, it was not shown in this data although UH's was.

3. The most productive authors

Who have contributed the most pages for the CHI audience to enjoy? Here's a table of the TOP 10 paper machines.

First author	Total page numbers
Brad A. Myers	66
Michael J. Muller	52
William W. Gaver	49
Steve Whittaker	48
Victoria Bellotti	48
Steve Benford	46
Ken Hinckley	45
Jun Rekimoto	44
Suresh K. Bhavnani	44
Tovi Grossman	44

If you compare this list to list no. 1, you see that the two lists overlap partially. Most of the top researchers of list no. 1 have published many important articles over the years, and by that way have secured their claim for fame. However, the high ranking of the two most highly cited authors, Ishii and Shardanand, seems to be established on only one "killer" publication.

4. The most cited papers

Okay, numbers are nice, but what kinds of papers have been influential? The following table should be indicative, if any statistic, of the most significant findings made in this area.

Title	First author	Year	Citings
Tangible bits	Hiroshi Ishii	1997	313
Social information filtering	Upendra Shardanand	1995	187
A focus+context technique based on hyperbolic geometry for visualizing large hierarchies	John Lamping	1995	126
Bricks	George W. Fitzmaurice	1995	111
Email overload	Steve Whittaker	1996	92
The WebBook and the Web Forager	Stuart K. Card	1996	92
i-Land	Norbert A. Streitz	1996	87
Virtual reality on a WIM	Richard Stoakley	1995	85
Augmented surfaces	Jun Rekimoto	1999	78
Recommending and evaluating choices in a virtual community of use	Will Hill	1995	77

Fine, what can one conclude about the most significant contributions to HCI, based on this list? I believe three kinds of contributions have been more important than others:

Presentation of a novel interaction paradigm (e.g., Tangible bits, Augmented surfaces, Focus+Context)
Presentation of a novel paradigm for computer-mediated human-human interaction
Identification of important HCI phenomena in widely used technologies (Email overload)

Again, the list of ALL top papers per year can be found here.

5. Expected citings

Assuming that you're lucky enough to get a paper pubbed at CHI, how probably is it going to be a killer paper like the ones listed above?

First of all, it depends on the type of the paper. In my data there are 4151 papers, of which 1214 are full papers. The average number of citations per paper is quite different in the two categories:

The average number of citings for full papers is 8.4
The average number of citings for all papers (incl. full papers) is 3.2

This measure should not be confused with Journal Impact Factor, as it is calculated differently (see this link).

This is of course an average that tells nothing about the distribution. It turns out that a majority, a whopping 61% of full papers, get less than 6 citations. See this table:

Citings	N	%
0	519	43
1 - 5	218	18
6 - 10	172	14
11 - 20	156	13
21 - 50	127	10
51 or more	22	2
Total full papers	1214	100

The 20/80 rule by Garfield (guy who invented Impact Factor in 1959) seems to apply here as well. According to this rule, the top 20% of papers get 80% of citings. I calculated that in CHI the top 21% of papers receive 76% of citings. Pretty close.

Moreover, the top 5% of papers have "robbed" amazing 38% of all citations to full papers.

6. Conclusions

CHI is the premier forum of HCI research. Full papers receive on average 8 citings in my data, which is a respectable number.
CHI has been, and it still is, an enterprise led by a small band of American universities and IT companies. The gold medal goes to Xerox PARC. The best individual "athlete" is Hiroshi Ishii from MIT.
The 20/80 rule seems to hold here.
The law of important articles seems to hold in CHI. According to the law, the number of important articles is the square root of the number of all articles, which in this case would yield 55 “important” full papers. These 55 top full papers (4% of all) received one third of all citations to full papers. Interestingly, according to the same law, the number of “revolutionary” articles is the logarithm of the total number of articles, which in this case would be 3. Ishii’s Tangible Bits is no doubt one of the most important papers in the history of CHI and therefore of all HCI. What would be the other "landmark" articles?
“The best of CHI” is dominated by constructive contributions. The most influential papers seem to be of two types: 1) a novel interaction paradigm/technique or 2) a novel paradigm to support human-human interaction. The most cited of such papers do not necessarily need to be backed up by rigorous empirical evaluation, because the technology itself has been so powerful a demonstrator. All of such papers have opened new vistas for research and founded a basis for continuity and development in research. Papers providing an empirical contribution, e.g., powerful observations about the use of a powerful technology like email, are salient but in the minority. I believe it would be beneficial to find a better balance between constructive and empirical papers.
Papers that attempt to develop the theoretical foundation of HCI are not visible. Most research efforts are technology-centered, making it difficult to "see the forest from the trees." As John M. Carroll said in his 1997 Annual Review of Psychology article, HCI needs more integrative work to systematize research efforts.
This little exercise shows that the scientometrics of HCI, if it is ever to be conducted seriously, will be challenging.

Abstract

Play stimulates in young students an understanding of history that would otherwise be difficult to engender, helping players to acquire historical notions. “Gaius' Day” is a game designed for mobile devices that supports young students learning history at an archaeological site. The game is structured like a treasure hunt. Groups of 4/5 players are formed: each group impersonates an ancient Roman family (playing historical roles strongly motivates students). The groups has to explore the city by collecting information, identifying places and noting them down on a map of the site. The group has the possibility to see on the phone the 3D-reconstruction of the identified places. When the game is over, teachers meet students for debriefing, to reflect upon their experience. Striving for a simple and cheap digital gaming infrastructure, the proposed design is based on cellular phones able to run a Java2 Micro Edition (J2ME), equipped with a memory card slot and also (optionally) a digital camera. Visitors will use their own cellular phone so that the archaeological site does not need to provide any hardware infrastructure. The recognition of the places is performed by visual tags or codes distributed across the site.

Short Biography

Carmelo Ardito is PhD student in Computer Science at the University of Bari, Italy. His research group is the Interaction Visulization Usability (IVU) group, coordinated by Prof. Maria Francesca Costabile (http://ivu.di.uniba.it). His current research interests are in the Human-Computer Interaction field, particularly information visualization techniques, usability evaluations and mobile systems. In the early phases of his PhD course, he studied information visualization techniques suitable to mobile devices. He developed PHiP (Patient History in Pocket, presented at MobileHCI ‘06), a tool designed for a mobile device that displays patient histories and permits to visually query patient data stored in the hospital database. Currently, his work is part of the CHAT project (“Cultural Heritage fruition & e-learning applications of new Advanced (multimodal) Technologies”), which aims at developing a software infrastructure that provides services accessible through thin clients such as cellular phones or PDAs. He proposes a scenario that can merge e-learning and cultural heritage: an excursion-game to support young students learning history at an archaeological site, by making use of recent advantages provided by mobile technology.

Video recording system for behavioral studies in the field

oulasvir — Wed, 28 Feb 2007 19:28:46 +0000

"Mobile usability lab"

A state-of-the art wearable (bearable:) video recording system, developed in the PASION project (EU FP6 Presence) to study mobile human-computer interaction. Tuomo Nyyssönen, perhaps the only expert in this field in Finland, was hired from Nokia Research Center to construct the system.

General goals:

Rich data collection
Easy post-trial data fusion
Realtime quality control
Flexibility
Unobtrusiveness
Longer operational duration.

Figure 1. The user (actually, Sauli). Carrying three cameras, wireless receiver, a quad, a recording device, and batteries.

Key improvements (in comparison to the previous generation system called ARMI, 2004):

Environmental cameras can be utilized, switching takes place automatically on the fly based on signal strength
Everything fits to a belt instead of a backpack (previously 4-5kgs)
Longer operation (4 hours without battery change)
Smaller cameras, better attachment mechanisms
New industrial design for "the pole" (used to attach cameras to the mobile device), supporting different shapes and sizes
Easier use of data (MPEG4, no digitization needed)
More robust, may actually survive the extreme weather conditions of Finland
Option for Bluetooth-triggered recording / shutdown events to save batterylife
All system components fit two aluminium suitcases that can be easily carried to the site.

Digital Economy

webmaster — Sat, 13 Jan 2007 12:01:30 +0000

Digital Economy (DE) has been merged into Digital Content Communities (DCC) research group. The information below is thus outdated!

Digital Economy covers the whole range of processes, mechanisms, and facilities that control, constrain, or support economic activities amongst partners operating in a market based on digital transactions. Research in the widest possible sense covers legal and self-regulation, in addition to aspects of "pure" information technology.

In accordance to the above, the main objective of the research carried out by the Digital Economy research group is to develop concepts, models, processes, facilities, platforms, and infrastructures that provide foundations for creating products and services for digital economy. The group studies, for instance, business models that facilitate and encourage the operation of digital markets. The special focus is on legal rules that govern emerging services. They include intellectual property rights (IPR), especially copyright, patents, and database protection, as well as privacy and data protection.

19 May 2006 - The project Peer-to-peer Fusion (P2P Fusion) concluded its negotiations successfully and will be launched in the beginning of June, 2006. The project addresses the current difficulties in the legal creative reuse of audio and video media in the Internet environment. It aims to create an open, accessible, legal and economically efficient environment for creative audiovisual cultural activities that can also be based on the work of others and materials from cultural institutions, through built-in, easy-to-use support for suitable licensing schemes. The consortium consists of 7 partners from Finland, Hungary and the Netherlands. The project is co-ordinated by TAIK. For more information contact Kari-Hans Kommonen at TAIK, khk(a)uiah.fi

24.11.2005: COMSOA project receives strategic TEKES funding

mam — Wed, 23 Nov 2005 22:00:00 +0000

The National Technology Agency TEKES awarded two-year funding for the project Community Media and Service-Oriented Architecture (COMSOA), originally submitted to the call of strategic research projects in the ICT domain at end of June. The project will focus on basic phenomena of community media, i.e., systems that enable and support social creativity, participatory media, and distributed problem solving viewed through the possibilities offered by service-oriented computing (SOC), a new emerging cross-disciplinary paradigm that has risen to offer solutions to various challenges in large-scale distributed computing. The planned research research will consist of (1) in-depth case studies of selected community media services, (2) development of new methods and tools for dynamic community analysis and modeling, (3) demonstration of the benefits of service-oriented computing by building extensions to service platforms being developed at HIIT, most notably to Digital Content Distribution Management System DiMaS, and to ALVIS, an open super-peer search engine, and (4) development of novel community-centric methodology for product and service concept design. For more information, please contact the leader of the project, Dr. Marko Turpeinen.
