Context aware hand-held devices:Licentiate thesis
No full textThe need to build devices that are more context aware has recently emerged. The motivation is to make devices easier to use on one hand, and decrease the information overload on the other. Context awareness should be helpful because it provides information to the device without bothering the user. In this thesis we concentrate on the context awareness of hand-held devices. Hand-held devices have special needs in the user interface, as they are small in size and fairly weak in performance. Moreover, they should also be easy to use while walking or doing something else. In the theoretical part of this thesis we analyze the possibilities that hand-held devices have for obtaining and exploiting contextual information. We propose use-case modeling and interaction scenarios to be used in revealing the potential use for context awareness. We also discuss the similarities between context awareness and agents. In the constructive part of the thesis we implement a general purpose sensor box which we use for increasing the context awareness of an example device. In the experiment we evaluate the theoretical ideas to gain hands-on experience of the practical problems involved in increasing context awareness of hand-held devices. Research into context awareness has been rather limited, especially in applying theories to practice. Research prototypes that use sensor information as a base of user interface operations have been built without much concern for the underlying principles. In this thesis we propose a theory for context awareness and show how it is used in practice
Sulautettu tulevaisuus, kehoverkosta sähköiseen apulaiseen
No full textPerinteisesti sulautetuilla järjestelmillä tarkoitetaan laitteita ja järjestelmiä, joissa käyttäjältä näkymättömissä oleva tietokone ohjelmistoineen kantaa suurimman vastuun vaadittavien toimintojen toteuttamisesta.Esimerkkeinä vaikkapa TV:n kaukosäädin ja auton ABS-jarrut. Tulevaisuuden sulautetuissa järjestelmissä prosessorit ja tietokoneet integroituvat huomaamattomaksi osaksi jokapäiväisiä toimintoja ja palveluita. Ainakin, jos maailman merkittävimpien tutkimuslaboratorioiden esittämät visiot toteutuvat
Methods and technologies for experimenting with ubiquitous computing:Dissertation
No full textInterest in ubiquitous computing (ubicomp) has increased dramatically during the past ten years. This trend is driven partly by the availability of enabling technologies and partly by the increased understanding that computers will eventually be everywhere and their use will change accordingly. This thesis present's work with two important subtopics of ubiquitous computing: context awareness and intelligent user interfaces. Methods are developed that firstly will make it easier to increase context awareness especially with personal technology devices and secondly enable the implementation of intelligent user interfaces as part of a smart environment. Context awareness is studied together with hand-held devices. The use of personal technology devices is analysed in order to find out possibilities for obtaining and exploiting context awareness. A sensor-box has been developed that is unobtrusively integrated into a hand-held device the user is carrying continuously with them. In this case context awareness is self-supportive, operating without the support of the surrounding infrastructure. Experiments with this device concentrate on improving the context awareness of a mobile phone used in everyday settings. Intelligent user interfaces are studied as a part of smart environments. By starting from smart environment scenarios a stack-based approach is used for defining more and more detailed requirements for each subsequent level. Finally a general-purpose platform, the SoapBox, that integrates sensors with wireless communications and computing in a small and versatile module that is easy to use in different designs and in various application domains has been defined, designed and implemented. The design examples consist of: a maze, dice, gesture control and responsive displays. Each of these highlights a different characteristic of user interfaces and smart environments and their role in ubiquitous computing. This study shows that it is possible to develop ubiquitous computing applications in a controlled and consistent manner. Methods are created that make it possible to achieve the ubiquitous computing vision with technical implementations. With personal technology devices interaction diagrams are used in revealing the possibilities for obtaining and exploiting context awareness. With smart environments a stack-based approach is used in defining the technology that enables intelligent user interfaces. In both cases the method leads to technical requirements that makes it possible to implement ubiquitous computing applications

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
