Multi-cursor multi-user mobile interaction with a large shared display
When using a mobile device to control a cursor on a large shared display, the interaction must be carefully planned to match the environment and purpose of the systems use. We describe a âdemocratic jukeboxâ system that revealed five recommendations that should be considered when designing this type of interaction relating to providing feedback to the user; how to represent users in a multi-cursor based system; where people tend to look and their expectation of how to move their cursor; the orientation of screens and the social context; and, the use of simulated users to give the real users a sense that they are engaging with a greater audience
Designing and evaluating mobile multimedia user experiences in public urban places: Making sense of the field
The majority of the worldâs population now lives in cities (United Nations, 2008) resulting in an urban densification requiring people to live in closer proximity and share urban infrastructure such as streets, public transport, and parks within cities. However, âphysical closeness does not mean social closenessâ (Wellman, 2001, p. 234). Whereas it is a common practice to greet and chat with people you cross paths with in smaller villages, urban life is mainly anonymous and does not automatically come with a sense of community per se. Wellman (2001, p. 228) defines community âas networks of interpersonal ties that provide sociability, support, information, a sense of belonging and social identity.â While on the move or during leisure time, urban dwellers use their interactive information communication technology (ICT) devices to connect to their spatially distributed community while in an anonymous space. Putnam (1995) argues that available technology privatises and individualises the leisure time of urban dwellers. Furthermore, ICT is sometimes used to build a âcocoonâ while in public to avoid direct contact with collocated people (Mainwaring et al., 2005; Bassoli et al., 2007; Crawford, 2008). Instead of using ICT devices to seclude oneself from the surrounding urban environment and the collocated people within, such devices could also be utilised to engage urban dwellers more with the urban environment and the urban dwellers within. Urban sociologists found that âwhat attracts people most, it would appear, is other peopleâ (Whyte, 1980, p. 19) and âpeople and human activity are the greatest object of attention and interestâ (Gehl, 1987, p. 31). On the other hand, sociologist Erving Goffman describes the concept of civil inattention, acknowledging strangersâ presence while in public but not interacting with them (Goffman, 1966). With this in mind, it appears that there is a contradiction between how people are using ICT in urban public places and for what reasons and how people use public urban places and how they behave and react to other collocated people. On the other hand there is an opportunity to employ ICT to create and influence experiences of people collocated in public urban places. The widespread use of location aware mobile devices equipped with Internet access is creating networked localities, a digital layer of geo-coded information on top of the physical world (Gordon & de Souza e Silva, 2011). Foursquare.com is an example of a location based 118 Mobile Multimedia â User and Technology Perspectives social network (LBSN) that enables urban dwellers to virtually check-in into places at which they are physically present in an urban space. Users compete over âmayorshipsâ of places with Foursquare friends as well as strangers and can share recommendations about the space. The research field of Urban Informatics is interested in these kinds of digital urban multimedia augmentations and how such augmentations, mediated through technology, can create or influence the UX of public urban places. âUrban informatics is the study, design, and practice of urban experiences across different urban contexts that are created by new opportunities of real-time, ubiquitous technology and the augmentation that mediates the physical and digital layers of people networks and urban infrastructuresâ (Foth et al., 2011, p. 4). One possibility to augment the urban space is to enable citizens to digitally interact with spaces and urban dwellers collocated in the past, present, and future. âAdding digital layer to the existing physical and social layers could facilitate new forms of interaction that reshape urban lifeâ (Kjeldskov & Paay, 2006, p. 60). This methodological chapter investigates how the design of UX through such digital placebased mobile multimedia augmentations can be guided and evaluated. First, we describe three different applications that aim to create and influence the urban UX through mobile mediated interactions. Based on a review of literature, we describe how our integrated framework for designing and evaluating urban informatics experiences has been constructed. We conclude the chapter with a reflective discussion on the proposed framework

Integrated context-aware and cloud-based adaptive home screens for android phones
This is the post-print version of this Article. The official published version can be accessed from the link below - Copyright @ 2011 Springer VerlagThe home screen in Android phones is a highly customizable user interface where the users can add and remove widgets and icons for launching applications. This customization is currently done on the mobile device itself and will only create static content. Our work takes the concept of Android home screen [3] one step further and adds flexibility to the user interface by making it context-aware and integrated with the cloud. Overall results indicated that the users have a strong positive bias towards the application and that the adaptation helped them to tailor the device to their needs by using the different context aware mechanisms

Entertaining situated messaging at home
Leisure and entertainment-based computing has been traditionally associated with interactive entertainment media and game playing, yet the forms of engagement offered by these technologies only support a small part of how we act when we are at leisure. In this paper, we move away from the paradigm of leisure technology as computer-based entertainment consumption, and towards a broader view of leisure computing. This perspective is more in line with our everyday experience of leisure as an embodied, everyday accomplishment in which people artfully employ the everyday resources in the world around them in carrying out their daily lives outside of work. We develop this extended notion of leisure using data from a field study of domestic communication focusing on asynchronous and situated messaging to explore some of these issues, and develop these findings towards design implications for leisure technologies. Central to our discussion on the normal, everyday and occasioned conduct of leisure lie the notions of playfulness and creativity, the interweaving of the worlds of work and leisure, and in the creation of embodied displays of affect, all of which may be seen manifested in the use of messaging artefacts. This view of technology in support of leisure-in-the-broad is strongly divergent from traditional entertainment computing models in its coupling of the mechanics of the organisation of everyday life to the ways that we make entertainment for ourselves. This recognition allows us to draw specific implications for domestic situated messaging technologies, but also more generally for technology design by tying activities that we tend to regard as purely functional to other multifaceted and leisure-related purposes
An Empirical Evaluation On Vibrotactile Feedback For Wristband System
With the rapid development of mobile computing, wearable wrist-worn is
becoming more and more popular. But the current vibrotactile feedback patterns
of most wrist-worn devices are too simple to enable effective interaction in
nonvisual scenarios. In this paper, we propose the wristband system with four
vibrating motors placed in different positions in the wristband, providing
multiple vibration patterns to transmit multi-semantic information for users in
eyes-free scenarios. However, we just applied five vibrotactile patterns in
experiments (positional up and down, horizontal diagonal, clockwise circular,
and total vibration) after contrastive analyzing nine patterns in a pilot
experiment. The two experiments with the same 12 participants perform the same
experimental process in lab and outdoors. According to the experimental
results, users can effectively distinguish the five patterns both in lab and
outside, with approximately 90% accuracy (except clockwise circular vibration
of outside experiment), proving these five vibration patterns can be used to
output multi-semantic information. The system can be applied to eyes-free
interaction scenarios for wrist-worn devices.Comment: 10 pages
