Introduction

How can people create their own

ubiquitous computing infrastructures, to

make it more personal , meaningful and

expressive?

Personalizing

Parasiting

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.

Introduction

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

Design Concepts

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]

Prototype 1 : Audio Tags

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

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?

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]

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?
