7 Aesthetic Urban Practices
Origins Aesthetic Urban Practices Urban sports: skateboarding parkour >> urban space as resource for aesthetic movements

8 Ubiquitous Computing Mark Weiser’s vision (1991) disappearing computer
Origins Ubiquitous Computing Mark Weiser’s vision (1991) disappearing computer everyday world literally used as interface away from desktop settings, available at hand in the real world: where needed, “where the action is” “The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it.” (Weiser) including when users are mobile social and physical: digitally augmented interface manipulating digital data = manipulating entities in the physical and social world

9 Ubiquitous Computing Implementing the vision
Origins Ubiquitous Computing Implementing the vision Mobile devices combined with computers embedded in the environment Awareness of physical & social context + each other >> Mapping the digital world onto the physical one >> User interface: tangible and embedded in the real world (e.g. post-hoc augmentation of everyday objects with sensors and networked communication)

10 Ubiquitous Computing Technologies context awareness mobile computing
Origins Ubiquitous Computing Technologies context awareness mobile computing tangible interfaces social navigation embedded sensor networks global positioning wearable computing augmented & mixed-reality ad hoc and p2p user networks etc obs! vem jag är + OBS! Inte blanda ihop med physcomp. Här handlar de tom att ge föremål ett nytt liv, parasita, ta vara på föremåls fysiska egenskaper, etc.

11 Ubiquitous Computing Examples “walk-up-pop-up” wearables
Origins Ubiquitous Computing Examples “walk-up-pop-up” wearables ambient displays intelligent work environments augmented, interconnected everyday objects etc Media cup, TecO obs! vem jag är + OBS! Inte blanda ihop med physcomp. Här handlar de tom att ge föremål ett nytt liv, parasita, ta vara på föremåls fysiska egenskaper, etc.

12 Ubiquitous Computing Everyday physical world:
Origins Ubiquitous Computing Everyday physical world: not designed for the purpose of these new activities offers a rich and heterogeneous variety of engaging interaction situates them in cultural and social context, with existing web of meaning more than a setting, a resource for computer-mediated aesthetic interaction >> Everyday activities as basis for interaction + everyday physical real world as interface everyday life as context of use - physical and mundane interactions - poetics of everyday life affordances, embodiment, user experience etc (SEE THESIS!!) post-production multidisciplinary approach in collaborative projects...

46 Interaction Properties
Locative media Interaction Properties Interactions happening anywhere, on the move : taking advantage of the mobile setting: playing with social and geographic dynamics implied by mobility >> outdoors everyday space, location and social context becoming resources for interaction as you move through space >> spontaneous & situated collaboration with people around or distributed across the city Background: aesthetic uses of public space (graffiti, parkour, situationism, etc) ubiquitous computing, consumer electronics and locative media sound-art (nime + sound installations in public space) sound & mobility in urban space themes and projects characteristics, challenges and design opportunities Technologies (sound specific) Discussion: new types of relationships between people and technology in urban space

47 Interaction Properties
Locative media Interaction Properties Interactions happening anywhere, on the move becoming embedded in the physical and social context of everyday life >> people managing interaction in heterogeneous context >> and in simultaneity with other activities (crossing a street... waiting for the bus...) Background: aesthetic uses of public space (graffiti, parkour, situationism, etc) ubiquitous computing, consumer electronics and locative media sound-art (nime + sound installations in public space) sound & mobility in urban space themes and projects characteristics, challenges and design opportunities Technologies (sound specific) Discussion: new types of relationships between people and technology in urban space tunA, Bassoli et al, Medialab Europe, 2002

48 Questions User-authored content spread
Locative media Questions User-authored content spread across public space: raises questions about property of information privacy & surveillance spamming? Augmenting environments and supporting activities with embedded computation: what if it changes what makes things what they are? If ubicomp spreads into public space, according to whose will? Top-down corporations, government vs bottom-up citizens, communities? Conflicts of interests? Background: aesthetic uses of public space (graffiti, parkour, situationism, etc) ubiquitous computing, consumer electronics and locative media sound-art (nime + sound installations in public space) sound & mobility in urban space themes and projects characteristics, challenges and design opportunities Technologies (sound specific) Discussion: new types of relationships between people and technology in urban space

49 Locative media Questions User control (Greenfield): How do you know you are interacting with a computer if invisible? How do you protect your privacy? avoid false commands? How do you know where to look for interaction? How to query/notify presence, access, place, manipulate media? How is the place? Who is there? What activities are going on there? How mobile is/are the user(s)? What meaning do the place, activities, and things around have and for whom? Background: aesthetic uses of public space (graffiti, parkour, situationism, etc) ubiquitous computing, consumer electronics and locative media sound-art (nime + sound installations in public space) sound & mobility in urban space themes and projects characteristics, challenges and design opportunities Technologies (sound specific) Discussion: new types of relationships between people and technology in urban space

50 Locative media Questions Ubicomp vs pervasive computing: at hand when needed vs always on everywhere Connect physical and virtual world: technical and HCI issue but also sociological, aesthetic, even political and environmental. F.ex. Yellow Arrow vs Geonotes: physical vs virtual markers Graffiti style interaction vs screen-based Background: aesthetic uses of public space (graffiti, parkour, situationism, etc) ubiquitous computing, consumer electronics and locative media sound-art (nime + sound installations in public space) sound & mobility in urban space themes and projects characteristics, challenges and design opportunities Technologies (sound specific) Discussion: new types of relationships between people and technology in urban space
