Abstract
This paper offers a reflection on the design space capturing interaction between private devices and public displays. Our aim is to map out the broad territory rather than present a specific interaction technique or application. The analysis of the design space covers (i) the range of possible interactions according with the number of devices vs. displays involved in the interaction, (ii) the type of the devices identified in terms of size and purpose, (iii) social context and audience characterised through number of participants and level of audience’s participation, (iv) levels of conflict between participants and audience in terms of content and pace, (v) spatial context in terms of levels of publicness and extent to which displays are part of the environment, and (vi) multiple device interaction described in terms of time-space matrix, and levels of coupling between public and private displays.
Keywords: public displays, private devices, design space
