For any questions relating to the applying procedure, please get in touch with the coordinator early on (available until 21.6.2012 and between 6.-10.8.2012.)

A successful candidate will have a good track record of high-quality research in the area of FuNeSoMo (depending on the career phase). The main target group of the call is senior candidates, but applications from graduate students are also more than welcome. The junior applicants must have at least a master's level degree and be enrolled as a graduate student in either Aalto University or University of Helsinki to be eligible to apply for funding from FuNeSoMo.

FuNeSoMo funding will cover the salary, daily allowance and travel expenses and a fixed sum for housing expenses during the research visits for the successful candidates. Additional family costs are for the most not covered from FuNeSoMo, but applicant is free to seek for complementary funding to cover these costs from elsewhere. The salary during FuNeSoMo funded exchange is based on HIIT/Aalto salary policy and the applicant will in most cases become HIIT/Aalto employee during the exchange. Applicants from companies should get in touch with the coordinator to inquire how to apply for funding from FuNeSoMo for a research exchange to ICSI or UCB.

The FuNeSoMo steering group will choose the best applications for funding. The funding decisions will be announced 24.8.2012 directly to all applicants.

FuNeSoMo has 2-3 calls annually. The next call deadline is planned for late 2012 - early 2013.

Dr. Asko Lehmuskallio, Researcher

alehmusk — Wed, 11 Apr 2012 13:29:41 +0000

I am interested in the kinds of relations we take with each other via techniques and technologies, especially with techniques of vision and looking. The aim of my research is to understand the social implications of technical solutions, such as of digitally networked cameras. How do specific artifacts act as a nexus in social relations?

My work builds on the premise that the ways in which we create techniques and technologies matter. In my understanding technical solutions tell us about social relations, and social relations are always maintained with techniques and technologies – although how this exactly happens is not always straightforward.

I have a background in social sciences (M.A. in cultural anthropology, PhD in media and communication studies), and enjoy my work with colleagues that often have different educations than my own, such as computer science or legal studies. My publications reflect both my background as social scientist, and joint efforts with diverse colleagues.

I have had the luck to both study and work at different universities in Europe and the US, among them Philipps-Universität Marburg, Staatliche Hochschule für Gestaltung Karlsruhe, Universidad Complutense de Madrid, Aalto University, and University of California, Berkeley. Additionally, I've given invited talks at several other universities (e.g. Humboldt-Universität zu Berlin), and completed a professional short program at MIT Media Lab.

Currently, I work as Researcher at Locating Media at the University of Siegen, as well as at the Tampere Research Center for Journalism, Media and Communication (COMET) at the University of Tampere.

Additionally, I am active in research networks, especially the Nordic Research Network in Digital Visuality (NNDV, funded by NordForsk), the DFG-network Media of Collective Intelligence and the HIIT Privacy group.

Recently, I've co-curated an exhibition called #snapshot at the Finnish Museum of Photography.

MIXSIG
HIIT Music Interaction Special Interest Group

MIXSIG presents a new type of collaboration within HIIT. It brings together researchers with expertise from various backgrounds with a common interest:
digital music

MIXSIG
Is not a single project
Is not a traditional research group

MIXSIG unites tacit knowledge and methodological competence from several disciplines

MIXSIG has some main challenges that influence our selection of research questions:

What music?
How music?

Given that "how (we acquire)" music issue is settled HOW do we select the music we want? Can abandon the old music interface concepts to provide a new types of musical experiences?

MIXSIG
Spans several existing research groups:
– Ubiquitous interaction (UIx)
– Adaptive computing (AC)
– Digital content communities (DCC)
– Empirical law & economy (ELE)

MIXSIG is presently related to following activities:
• Musiquitous (2009-2012) @UIX
• EMOKEITAI (2009-2011) @DCC
• DCM, Laila (2008-2010) @ELE
• Cappella@AC

workshop on mobility and environment ~ april 21, 2008

oulasvir — Mon, 03 Mar 2008 18:15:54 +0000

A workshop with Nokia Research Center Palo Alto and Ubiquitous Interaction (UIx) of HIIT
April 21 2008, at Nokia Research Center Palo Alto, CA

Purpose:
Unlike desktop-based computing, mobile computers are regularly exposed to drastic changes in surroundings. These include technical changes, as changes in network conditions and resource availabilities, but also cognitive and social. We believe that a deep understanding of the mobile environment will be the basis for the next generation mobile human-computer interaction models. In this workshop, we would like to explore how mobile applications can leverage context both explicitly as in context-aware applications and implicitly through means of user interface design. The goal of this workshop is to bring together mobile application developers and user researchers to discuss the impact of the changes in environment to the use of mobile technology. We would like to develop ideas and approaches to better understand how mobile computers can mediate user-environment interaction.

Schedule:

09.30 - 09.45: Introduction to the workshop
09.45 - 10.00: Ann Morrison: The zone of progressive activity: Designing for locative mobile experience

The Zone of Progressive Activity: Designing for Locative Mobile Experience
Ann Morrison
The Practice of Locative Experiences" is a workshop paper that was presented at Digital Arts and Culture Conference 2005 (DAC), Denmark that discusses a framework to ensure essential elements are continually re-cycled back into complex design problems. This method was developed in response to designing an initial set of trials for a Mobile Locative User Experience for the transient back packer community in Brisbane, Queensland, 2004, as a part of Australasian CRC for Interaction Design (ACID) projects. Similar principles form the backbone in looking at designing User Trials (and ultimately successful use experiences) for Augmented MapLens technology, which had its first light-weight user trial in Helsinki, March 2008 (HIIT).

Personalised mobile ubicomp applications in public spaces
Peter Peltonen and Petri Saarikko
We present the PUPS project, which purpose is to design, implement and field trial prototypes of novel ubicomp applications that combine context-awareness with personalisation in order to provide a better user experience in everyday tasks in public spaces. We present two application prototypes: Massive, a mobile shopping assistant, and Funnelry, a mobile social media aggregator.

Ubiquitous media for performative interaction and collective experiences
Giulio Jacucci
Prototypes and field evaluation demonstrate that mobile and ubiquitous applications can contribute to sustain performative actions (embodied, expressive and experiential) and collective experiences. Conceptual work aimed at better articulating these actions and experiences could provide a more conscious, critical and grounded constructive research.

Large-scale experimentation of mobile social media applications: The OtaSizzle project
Martti Mäntylä
Our accumulated experience in designing digital customer services, such as Jaiku.com, www.kuvaboxi.fi, and comeks.com, suggest design principles dealing with the service life-cycle. They include: how to gain the interest of the user at first encounter; how to hold it during the process of service appropriation; and how to make the contact durable. However, even though the evidence towards these principles is clear, and comes from several parallel sources, a number of open lines of research remain: How do the principles scale with the size of the user population? Are some further design rules needed to deal with larger crowds? Just how general are these rules? Are there also domain-specific rules (what it yes, what distinct domains are identifiable)? The successful services are also characterised by continuous contact with users and very rapid evolution (daily builds). Is there some larger principle behind this? The recently started OtaSizzle project is designed to study these issues. We plan to build services following the above principles, focusing on service initiation; hooking the user; and building a durable relation. We will test the services them with sufficiently large user populations and over sufficiently long time to see the dynamics of service diffusion and the impact of various principles. To achieve this, we will involve partners with access to large user populations and service infrastructures for reaching the users and deploy multi-disciplinary researcher resources for really studying, understanding and explaining the phenomena taking place.

Field testing of mobile location-aware systems
Timo Partala
This presentation addresses problems related to studying mobile location-aware systems in the field. Recent field experiments on car navigation and location-aware mobile learning are discussed, and a design for an upcoming field experiment on streaming mobile videos from public events is also presented. The meaning of environmental variables in the field testing of mobile location-aware systems is discussed.

Mobile web challenges in mobile meeting service
Alison Lee
The mobile phone is a critical and common accoutrement of mobile workers. Yet, except for communication, email, and personal information management tools, there are many traditional computing capabilities and business activities (e.g., productivity tools, meetings) that remain unsupported on mobile phones. EZMeet is first exemplar of a service offering developed to enhance the mobile business user experience. It is a Web-based meeting service developed with AJAX and Apache/Python technologies that works on a variety of browser-enabled smart phones. A pilot of this service within Nokia has just begun. In rethinking electronic and face-to-face meetings for the mobile context, our design and development has sought to lower the barriers to meetings in order to nurture new and emerging meeting behaviors facilitated by mobility and mobile technologies. We present the capabilities of this service, illustrate some scenarios of collaborative use, and describe some key usability and sociality issues impacting initial adoption. The discussion of issues touches on familiar topics related to input and output modality challenges but it will be couched in terms of needs and requirements posed by meeting activities, collaborative-application support, and longer-lived activities (conducting meetings compared to reading email, accessing calendar, sending SMS). We will also discuss our experiences with using AJAX and Web technologies to deliver services on mobile phones supporting different browser technologies (e.g., Firefox, Opera, S60 OSS).

Designing interactions for 3D mobile maps
Antti Nurminen
Mobile 3D maps could be the next generation of navigation and location based information browsing, offering an intuitive gateway to the environment. However, navigation is not just model viewing, and 3D maneuvering requires control over many dimensions. We present the problem of 3D interaction with limited inputs, and our first solutions. What methology would be most suitable for rapid development of interfaces for a new family of applications?

Mobile services using online collections of geotagged photos
Radek Grzeszczuk
Providing mobile services, such as image-based information retrieval or landmark-based navigation, faces the problem of lack of content. Building suitable databases is a daunting task. Brute-force acquisition is very costly and the information goes quickly out of date. A promising approach of addressing this issue is to use online collections of geotagged photos. With the emergence of camera- and GPS-equipped mobile phones, the growth of this resource is bound to accelerate in the near future. In this talk, we describe a method for adaptively maintaining a database of user-contributed images. We show that such database scales gracefully with addition of new data and adapts to changing environments. We then describe two applications built on top of this resource: a robust image-based information retrieval system for mobile devices and a landmark-based navigation system that uses an online collection of geotagged photos for automatically generating navigation instructions.

EveryBit
Rich Hankins
Mobile devices provide a wealth of information and abundant opportunities for building highly personal services, as well as understanding large-scale social patterns. Many researchers, startups and established Internet service companies are currently experimenting with novel applications based on this personal data. Unfortunately, a lot of infrastructure often needs to be built just to prototype and experiment with these services, and it is rarely known initially what data is most important to collect, requiring many experiments and iterations on prototypes. To ease the situation, we have created Everybit, a community platform for mobile data collection, aggregation, and dissemination. The Everybit system consists of three components: (1) client software for collecting context, content, and community data from mobile devices; (2) server software for aggregating and indexing this data; and (3) a simple HTTP-based API for storing and querying data on the server. While the system is conceptually simple, it greatly reduces the effort required to collect, analyze and publish mobile data. As a result, researchers can rapidly prototype new services, possibly leveraging other web-based services (such as Google Maps), and test out theseservices on a community of users. In this short presentation, I'll go over the design of the Everybit system and show how it's currently being used within the C3 team.

Sustainable Interaction Design for Mobile Phones
Elaine Huang (Motorola Labs)
As electronic waste and mobile device proliferation present an increasing ecological problem, industry has responded by working towards more environmentally sustainable solutions largely through advances in materials science and industrial design. In this research, I investigate how interaction design informed by studies of current phone ownership practices can play a complementary role in the design of mobile phones that support more sustainable ownership practices. Through qualitative studies of people's practices for replacing and disposing of mobile phones, this work uncovers some of the challenges to sustainable practices and the complexity of the decision-making processes involved in mobile phone ownership. Based on these studies, this research identifies design opportunities and interface ideas for mobile phones that can help provide users with information and options regarding environmentally sustainable phone practices. Such interaction design, in parallel with materials science, industrial design, and advances in other areas, is a step towards solving the e-waste problem posed by ubiquitous computing devices. In addition, I will also touch upon other current and recent themes in my research, including ethnographic studies of social networks throught the United States that seek to understand how people maintain connectedness within their networks of friends and family through social exchange through a variety of conventional and technological media.

Semantic graphics for more effective visual communication
Vidya Setlur
Computers are becoming faster, smaller and more interconnected, creating a shift in their primary function from computation to communication. This trend is exemplified by ubiquitous devices such as mobile phones with cameras, personal digital assistants with video, and information displays in automobiles. As communication devices and viewing situations become more plentiful, we need imagery that facilitates visual communication across a wide range of display devices. In addition, producing effective and expressive visual content currently requires
considerable artistic skill and can consume days. The goal of my research is to develop new techniques and user interfaces that enhance visual communication, while making it fast and easy to generate compelling content. New algorithms in semantic graphics, i.e. combining concepts and methods from visual art, perceptual psychology, information processing, and cognitive science, help facilitate users in creating, understanding and interpreting computer imagery. In this talk, Vidya Setlur will present the usage of semantic graphics for various information visualization goals.

Tagging in ZoneTag and Jaiku
Sami Vihavainen
Development of mobile phone technology and mobile data transfer technology has generated web 2.0 related mobile services that enable people to share information with their social network regardless of time or location. One specific technology often part of these services is tagging. Tagging itself is not anymore a new innovation. It has been a feature in many web 2.0 services (social tagging systems) for several years. Social tagging systems in mobile terminal are however quite new. Like from desktop terminal also from mobile terminal people can use tags for both to organize information and to communicate with other people. However, mobility has brought especially location tagging into a more interesting light. With a mobile phone it is possible for user to add a location tag to her camera phone photo right after taking it, or to tag her current location and share that information to her friends via microblogging service. In this presentation I’ll show preliminary results from our recent case study, where two mobile/web based social media services, Zonetag/Flickr and Jaiku, were introduced and given to three social groups: high school friends (Finland), interest group of bird watcher (Finland), and group of ‘hipster’ friends in their 30’s (USA), to use mainly for their inner communication. Based on those results I’ll argue that although there are advantages in using location tags for communicating with one’s social network it is not always self evident that people use them. I’ll also argue that the technology itself and the structure of a social group can affect on the appropriation of the tagging technology, especially in location tagging.

I have been a researcher since 2000, and from 2011 I have worked primarily as the head of ux & service design at a Finnish software company Futurice. I'm also a docent (i.e., adjunct professor, reader) at the Aalto University School of Science.

My latest major academic work is a book co-authored by David Frohlich and published by Springer in February 2011. It is on domestic photography as a socio-technical system in transition: "From Snapshots to Social Media – The Changing Picture of Domestic Photography".

I have worked in the Helsinki Institute for Information Technology HIIT since 2001. In 2008-2011 I ran the Self-Made Media research group at HIIT. In 2002-03 I was a visiting scholar in the School of Information (iSchool) at the University of California, Berkeley. The year 2009 I was a visiting fellow at the Digital World Research Centre in University of Surrey, UK.

I got my doctoral degree from the Helsinki University of Technology (TKK) in December 2006. The dissertation was about domestic photography, metadata and software design. I'm still very proud that the thesis was awarded by the Finnish Information Processing Association, it was also one of the 17 finalists for the ERCIM Cor Baayen Award 2007, and the thesis was one of the two theses from the CS department nominated for the TKK thesis of the year.

Parsimonious Modelling

tmantyla — Wed, 31 Jan 2007 10:55:16 +0000

The research group Parsimonious Modelling of the Helsinki Institute for Information Technology HIIT operates on the Department of Information and Computer Science (ICS) of the Aalto University School of Science, in Finland. It is part of the Algorithmic Data Analysis (Algodan) Centre of Excellence, elected by the Academy of Finland.

The research group Parsimonious Modelling develops novel computational data analysis methods and applies these methods on two application fields: cancer genomics and environmental informatics. Parsimonious modeling aims at simple, compact, or sparse models as a result of learning from data in the presence of very little or no a priori information about the modeled problem. Simplicity of the models facilitates understanding of the problem domain by humans.

Both application fields present similar challenges to the data analysis problems: the high dimensionality of observed data and the presence of moderate or large noise levels are both factors that bear fundamental problems for any data analysis. Seeking new areas of application and interfacing the newest application domains with lots of novel types of generated data helps in finding new, unsolved settings of problems.
