’Eyes free’ in-car assistance: parent and child passenger collaboration during phone calls

This paper examines routine family car journeys, looking specifically at how passengers assist during a mobile telephone call while the drivers address the competing demands of handling the vehicle, interacting with various artefacts and controls in the cabin, and engage in co-located and remote conversations while navigating through busy city roads. Based on an analysis of video fragments, we see how drivers and child passengers form their conversations and requests around the call so as to be meaningful and paced to the demands, knowledge and abilities of their cooccupants, and how the conditions of the road and emergent traffic are oriented to and negotiated in the context of the social interaction that they exist alongside. The study provides implications for the design of car-based collaborative media and considers how hands- and eyesfree natural interfaces could be tailored to the complexity of activities in the car and on the road

The role of digital technologies during relationship breakdowns

Relationship breakdowns are undoubtedly difficult. Access to and use of technology can exacerbate the situation. In our networked society, shared lives generate vast amounts of shared digital data which can be difficult to untangle, whilst social media can provide an outlet to emotions that can take a public and often persistent form. In this paper, we report on a qualitative study that considered the role of technology in the process of a relationship breaking down. Four main themes emerged in our findings: communicating about the separation, change in social status, shared digital assets, and moving on. Opportunities for design are identified in reducing misunderstandings via CMCs, enhancing social media, supporting intimacy in distributed families, and refining service provision

Älykäs tunnistauminen ja käyttöoikeuksien hallinta monimuotoisessa verkotetussa maailmassa

Our living environments are full of various connected computing devices. These environments in homes, offices, public spaces, transportation etc. are gaining abilities to acquire and apply knowledge about the environment and its users in order to improve users' experience in that environment. However, before smart adaptive solutions can be deployed in critical applications, authentication and authorization mechanisms are needed to provide protection against various security threats. These mechanisms must be able to interoperate and share information with different devices. The thesis focuses to questions on how to facilitate the interoperability of authentication and authorization solutions and how to enable adaptability and smartness of these solutions. To address questions, this thesis explores existing authentication and authorizations solutions. Then the thesis builds new reusable, interoperable, and adaptive security solutions. The smart space concept, based on semantic web technologies and publish-and-subscribe architecture, is recognized as a prominent approach for interoperability. We contribute by proposing solutions, which facilitate implementation of smart access control applications. An essential enabler for smart spaces is a secure platform for information sharing. This platform can be based on various security protocols and frameworks, providing diverse security levels. We survey security-levels and feasibility of some key establishment protocols and solutions for authentication and authorization. We also study ecosystem and adaptation issues as well as design and implement a fine-grained and context-based reusable security model, which enables development of self-configuring and adaptive authorization solutions.Ympäristöt, joissa elämme, ovat täynnä erilaisia verkkolaitteita. Nämä koteihin, toimistoihin, julkisiin tiloihin ja ajoneuvoihin muodostuvat ympäristöt ovat oppimassa hyödyntämään ympäriltä saatavilla olevaa tietoa ja sopeuttamaan toimintaansa parantaakseen käyttäjän kokemusta näistä ympäristössä. Älykkäiden ja sopeutuvien tilojen käyttöönotto kriittisissä sovelluksissa vaatii kuitenkin tunnistautumis- ja käyttöoikeuksien hallintamenetelmiä tietoturvauhkien torjumiseksi. Näiden menetelmien pitää pystyä yhteistoimintaan ja mahdollistaa tiedonvaihto erilaisten laitteiden kanssa. Tämä lisensiaatin tutkimus keskittyy kysymyksiin, kuinka helpottaa tunnistautumis- ja käyttöoikeusratkaisujen yhteensopivuutta ja kuinka mahdollistaa näiden ratkaisujen sopeutumiskyky ja älykäs toiminta. Tutkimuksessa tarkastellaan olemassa olevia menetelmiä. Tämän jälkeen kuvataan toteutuksia uusista tietoturvaratkaisuista, jotka ovat uudelleenkäytettäviä, eri laitteiden kanssa yhteensopivia ja eri vaatimuksiin mukautuvia. Älytilat, jotka perustuvat semanttisten web teknologioiden ja julkaise-ja-tilaa arkkitehtuurin hyödyntämiseen, tunnistetaan työssä lupaavaksi yhteensopivuuden tuovaksi ratkaisuksi. Tutkimus esittää ratkaisuja, jotka helpottavat älykkäiden tunnistautumis- ja käyttöoikeuksien hallintaratkaisujen kehitystä. Oleellinen yhteensopivuuden mahdollistaja on tietoturvallinen yhteensopivuusalusta. Tämä alusta voi perustua erilaisiin avaintenhallinta ja tunnistautumisprotokolliin sekä käyttöoikeuksien hallintakehyksiin. Tutkimuksessa arvioidaan joidenkin olemassa olevien ratkaisujen käytettävyyttä ja tietoturvatasoa. Tutkimuksessa myös tutkitaan ekosysteemi- ja sopeutumiskysymyksiä sekä toteutetaan hienojakoinen ja kontekstiin perustuva uudelleen käytettävä tietoturvamalli, joka mahdollistaa itsesääntyvien ja mukautuvien käyttöoikeuksien hallinta sovellusten toteuttamisen

Crossing Boundaries: Patients’ Experiences of using a Diabetes eHealth System

This thesis is concerned with exploring patients’ experiences of using a diabetes eHealth system. The context of the study is the growth of interest in eHealth systems that focus on patient needs, alongside increasing home computer use and the rising incidence of chronic diseases, such as diabetes. I aim in this thesis to make a novel contribution to knowledge about how eHealth technology is experienced by patients with diabetes. The study takes the form of a qualitative enquiry into the use of a diabetes eHealth system by a group of patients and their healthcare practitioners at a primary care general practice in Northern England. Using symbolic interactionism as a methodological perspective and taking elements from grounded theory the study produces a theoretical framework based on a thematic analysis of participants’ descriptions of their experiences of using the eHealth system. A diabetes eHealth system was designed and built for the study, and 38 patients were recruited from a single GP practice using purposive sampling. Participants used the system for six months and were interviewed at the beginning, middle and end of the study period. Issues of surveillance, automation, endorsement and interaction influenced use and experiences of the system. Results from the study indicate that participants use and perceive the eHealth system as part of their diabetes management experience. My thesis is that the eHealth system is a boundary structure through which boundary objects, such as electronically formatted blood glucose readings, are created and shared across different social worlds. The eHealth system crosses the boundary between two spheres of an individual’s diabetes management experience, the personal sphere of self-management, and the external sphere of seeking and receiving support from medical experts and others with diabetes. The co-location of these two spheres exposes participants to scrutiny but also opens up new possibilities for collaboration and learning

Technology and the family car: situating media use in family life

This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonThe thesis describes how family life is organised in the car, with a particular focus on exploring the role and use of mobile technology in this setting. The objective of this research is to use the insights from video ethnographic data collected with families to discuss how social interaction between family members may be situated to technology use. Drawing from the notion of ‘ordinary work’ discussed in ethnomethodology and applying this to naturalistic video data of families in cars, the thesis demonstrates how family activities are locally produced, drawing on background knowledge and common-sense understandings of family members’ work. Using methods from conversation analysis, the research demonstrates how transcribed instances of talk can reveal how parents and children produce their actions and talk to jointly produce activities in relation to media use. The analysis presented in this thesis demonstrates how the family car provides an opportunity for parents and children to come together, and engage in mundane family activities of talk and play while using a range of mobile devices. The thesis draws on richly documented and closely analysed episodes of interaction to demonstrate how family life unfolds in the accomplishment of activities in which interactions are situated, orderly and observable. The production of family life within the car involves talk and embodied action that is artfully placed within interactions between parents, children and technology. The analysis elucidates how the features of negotiation, collaboration and coordination around device-use are placed alongside driving activities. The contributions of this thesis lie in providing a descriptive analysis of the social organisation of family life through technology, developing an understanding of family technology use in a mobile context and highlighting elements of interaction that will inform the development of insights for the design of technology that is sensitive to the nuances of family life, mobility and technology practices.EPSRC and Microsoft Researc
