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 ‘democratic jukebox’ 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

Guiding the design and implementation of interactive public displays in educational settings

Interactive Public Displays (IPD) enable new ways of interaction as well as communication channels, extending online communities into physical places and supporting a culture of participation. While educational environments have seen how new digital technologies can enhance learning activities beyond the traditional classroom context, the use of IPDs is still an area insufficiently explored. This paper proposes a set of design goals for the implementation and deployment of engaging interactive public display applications in educational settings. Based on findings from a series of design workshops and two deployment studies in authentic settings, seven design goals were identified and defined. The design goals provide clear guidelines for the design of IPDs for schools by making design teams and stakeholders focus on factors fostering user adoption, social interactions and collaboration. The design goals also opened up paths for further explorations regarding display awareness, level of commitment in interactions, the displays’ integration into structured activities, and display management at the educational institutions

Situated Public News and Reminder Displays

Abstract. In this paper we present concepts for and experiences with a Situated Public Display system deployed in a university setting. We identify the rate with which information is updated as an important property to distinguish different kinds of information. With a first slideshow based prototype it was very difficult for users to predict whether information was updated since they last looked. To solve this problem, we took a broader view and conducted a contextual inquiry to investigate how people deal with paper based posters. We deduced an information flow diagram that identifies roles of people and categories of posters and noticeboards. We identified actionables, that is, posters that offer people to take a specific action, as a special type of information to support. We identified two strategies, planning and opportunism, to deal with actionable information. We present a system using two kinds of displays, News Displays and Reminder Displays, to support both strategies. We show how auctions can be used for Reminder Displays to select those information chunks that are most important in a particular context. Finally, we present an evaluation and lessons from the deployment.
