A series of low-tech prototypes drawing inspiration from existing urban practices, are tested in real settings with the general public. We stage the prototypes as props and people as performers to discover and uncover emerging behaviours, and to derive design implications for location-based information systems that make full use of the physicality of public spaces.

INTRODUCTION and augmented reality [e.g. 5, 9 11 12], interaction design [e.g. 1, 6, 7] and in particular to location-based information systems [e.g. 1.1 Motivation 4], which connect digital information to physical space. For Prompted by the excess of commercial media pervading the example, the project Hear&There enables people to leave virtual public arena, the research and design project Tejp aims at audio imprints at particular places, with content that is created by encouraging playful ways for indivduals to personalise territory the users themselves, located with GPS on a map through a PDA, and at providing a space and sounding board for existing social and accessed through headphones. GeoNotes focuses on the relationships between residents, passers-by and potential players “communicatory, social and navigational implications of the mass in the public arena. The aim of the project is to provide usage” [4] of text-based systems, addressing the issue of technological tools and situations for layering personal traces on information overload and introducing the notion of social public physical spaces for others to discover. We promote filtering. technologically enabled personal expression that can happen any day, in any public space without the need for group organization In Tejp, we concentrate on the tangible and semantic aspects of or ownership of specific devices. interaction between the user and that information space, and take advantage of the physicality of the environment. The ultimate goal Builiding upon existing alternative channels of public expresion is to facilitate the personalisation of public spaces by everyday and communication for everyday people such as graffiti, stickers, people, exploring parasitic communication as means of adding posters and bulletin boards, we perform a series of experiments by and revealing layers of content on physical space. deploying low-tech prototypes in the public realm.
