1. Tejp: Ubiquitous Computing as Expressive Means of Personalising Public Space ACM – UbiComp, 2003 Jacobs, M., Gaye, L. and Holmquist, L.E. 2008. 10. 9 C.K. Hong

2. Introduction How can people create their own ubiquitous computing infrastructures, to make it more personal , meaningful and expressive?

3. Introduction Graffiti Expressive Personalizing Parasiting

4. Introduction • Main idea • Expressive ubiquitous computing • Step towards a more poetic, strange, and personal expression in ubiquitous computing • Personalizing public space • Create layers of personal information and meaning in public space • Parasiting and Detournment • Purpose of the project • Observe how emerging information content and user behaviours are influenced by the characteristics of the prototypes • Exploring the actual physical interaction between the users and the information space. • Low-tech prototypes which are not meant to become end-products.

5. Design Concepts • Parasitic media • Adding functionality, which is invisible , to a pre-existing system within the system margin of error • Graffiti • Detournement • Deflection, diversion, misappropriation, hijacking, or otherwise turning aside from the normal course or purpose • Reusing elements of well-known media to create a new work with a different message, often one opposed to the original

6. Prototype 1 : Audio Tags • Overlaying personal traces on public space • contains an audio message that once recorded can be left at hidden places in public spaces. • When passers-by lean towards the device, this personal message is whispered to their ears. From ref.[3]

7. Prototype 2 : Glitch • Revealing a hidden layer of personal communication in public space • Array of loudspeakers picking up electromagnetic interferences from mobile phones. • Interferences caused by passers-by’s messages and phone calls, are loudly broadcasted at a public place [From Author’s home page]

8. Conclusion • Expressive ubiquitous computing environments • explores how to empower people with open pervasive means of structuring and personalizing their everyday environment through overlaying and uncovering meaning on public, physical space. • Is that all?

9. Others’ opinions • “Create playful or ambiguous experiences as a means, not only as an end, of research”[1] • “New types of personal creativity and expression” [2] • “Explores how temporal qualities can shape the social and spatial form for a communications system.”[3]

10. My Opinion(What I learned?) • Expressive Ubiquitous Computing • Learning from design theory • Parasiting media => “Invisibility” • Detournement => “Distributed output” • XXX Ubiquitous Computing • Creative Ubiquitous Computing? • Clean Ubiquitous Computing?
