Application diversity in open display networks

We envision that future public display networks will be more interactive and open to applications from third parties similar to what we already have with smartphones. This paper investigates the application landscape for interactive public displays aiming to understand what would be the design and usage space for this type of applications. In particular, we explore people’s perceptions and expectations regarding the diversity of applications that may emerge in future application ecosystems for public displays. We have devised a research methodology anchored on what is currently the rich and diverse range of applications in the mobile application market. We used a set of 75 mobile applications from Google Play application store and asked 72 participants about their relevance for public displays. The results showed that people had a clear preference for applications that disseminate content, and also that these preferences are affected by the type of location where the displays are deployed. These insights improve the understanding of the variables that may affect diversity in future display application ecosystems and inform the development of potential app stores in this context.Fundação para a Ciência e a Tecnologia (FCT

Dealing with mobility: Understanding access anytime, anywhere

The rapid and accelerating move towards the adoption and use of mobile technologies has increasingly provided people and organisations with the ability to work away from the office and on the move. The new ways of working afforded by these technologies are often characterised in terms of access to information and people ‘anytime, anywhere’. This paper presents a study of mobile workers that highlights different facets of access to remote people and information, and different facets of anytime, anywhere. Four key factors in mobile work are identified from the study: the role of planning, working in ‘dead time’, accessing remote technological and informational resources, and monitoring the activities of remote colleagues. By reflecting on these issues, we can better understand the role of technology and artefact use in mobile work and identify the opportunities for the development of appropriate technological solutions to support mobile workers

Is the writing on the wall for tabletops?

We describe an ethnographic study that explores how low tech and new tech surfaces support participation and collaboration during a workshop breakout session. The low tech surfaces were post-it notes and large sheets of paper. The new tech surfaces were writeable walls and a multi-touch tabletop. Four groups used the different surfaces during three phases: i) brief presentation of position papers and discussion of themes, ii) the creation of a group presentation and iii) a report back session. Participation and collaboration varied depending on the physical, technological and social factors at play when using the different surfaces. We discuss why this is the case, noting how new shareable surfaces may need to be constrained to invite participation in ways that are simply taken for granted because of their familiarity when using low tech materials
