An Experiment in Located Media Experiences Ed Leland Introduction What is the Mobile Bristol Project? Experimental testbed for pervasive mobile media located in Bristol, UK from November 2002 August 2005 Focused on both technology and user value research

Collaborative activity between industry, universities, content providers and government Funded by the UK Department for Trade and Industry (DTI) from November 2002 August 2005 Purpose To investigate how mobile devices and wireless technology can be used to

enhance the ways in which residents and visitors experience and interact with their physical environment and with each other in urban and public spaces Vision: A Platform for Situated Experiences Provide a digital canvas over the city onto which rich digital experiences can be painted and new commercial ventures can be explored

Wireless & wired Networks Context-sensitive clients, services and experiences Right thing at the right time, in the right place, in the right way Creating another Dimension City as a showcase, canvas and lab Participants Principal founders: Hewlett Packard Laboratories University of Bristol

different kinds of people with an eye toward the design of new technologies. Goal is to use this understanding to develop new technology concepts, and to help shape and direct other technologies currently under development in ways that people will find valuable. Context sensitive based on what User Group is involved Initial research focused on working parents Experience Design Research

Centered on two main questions: What makes a technology experience compelling? How do you design situated technology experiences? Single Site, Multiple Sites, Single Application Single Application (Fusion) (Roaming)

Single Site, Multiple Applications (Discovery) Multiple Sites, Multiple Applications (Integration) Application Framework The

framework reflects an emerging, mixed-reality metaphor for Mobile Bristol applications and consists of three main components: An XML based specification language for laying out the virtual world of the application and defining how client devices should respond to events A PC-based graphical authoring tool for creating application specifications in this language Portable client hardware and software that can download and interpret such specifications

Infrastructure Rollout The goal for the Mobile Bristol network is to establish as wide a coverage of wireless LAN as possible in the center of Bristol Three tiers of access: Tier 1: 802.11 access points to BMEX backbone Tier 2: 802.11 access points to Internet Tier 3: Mobile Phone network access to Internet Application Projects

Public launch (March 2003) Players use an iPaq handheld computer to solve musical puzzles. Users can play individually or invite other users in the bar to join in a group game. Designed to promote social interaction and test acceptability of new technologies in social spaces

Implemented May-July 2003 Used 36 children, ages 9-10 to provide input. The children gave their thoughts and feelings about Old Chapel Park, a familiar outdoor space They were then given a set of hardware and software tools to create soundscapes in that space. Fielded July- November 2003 Uses portable, handheld technology to access location

specific information Focused on the rich history of the Bristol docks Allows for interaction with other users and the ferry staff Designed as an example of an Open Space tourism service, suitable for a park, castle or city district. Proof of concept test Autumn 2003 Futurelab saw the opportunity in utilizing the Mobile Bristol framework for

educational purposes when they participated in our first set of workshops with local schools. Savannah is a collaborative project that explores whether children can learn about ecology and ethology by 'being an animal'. The project is motivated by the question of what innovation and creativity mobile technologies and rich media delivery can bring to ways of learning in a game play environment. The idea of the game is for participants to learn what it is like to be a lion by walking around in a virtual Savannah and encountering sounds of other animals or things in the environment.

Field trail and user evaluation (October 2003) The interactive Jukebox is designed to allow a community of people in a public space (e.g. a bar or caf) to all partake in the choice of music playing Owners of the bar/cafe create MP3 music collections from which candidate tracks are nominated to be voted on by the clientele. People in the bar use wireless iPAQ handheld to view nominated tracks, find out further information about the tracks and submit their votes

Votes are collated across all the iPAQs to determine the next track providing a democratic choice over the music played Bursary projects: November 2003-November 2004 Schminky demonstrated that it was possible to introduce technology mediated experiences into the heart of a social space without destroying the ambiance The project gave us the incentive to explore the integration of interactive exhibition systems into the lifestyle experience of a visit to Watershed. The aims of the bursary: To enable artists and multi media producers to develop their creative practice in digital media

and specifically to work with mobile technologies To explore the integration of interactive exhibition systems into the lifestyle experience of a visit to the Watershed. To foster creative collaborations between artists, technologists and Watershed to explore new working practices To develop the Mobile Bristol Infrastructure through practice based R&D To make digital work and practice available to audiences in the South West through seminar, presentation, exhibition and/or publication To support opportunities for exchange of ideas in the wider community Works initially shown to an invited audience (February

2004) Consists of two separate interactive artworks Both Zoe and Dan used kit consisting of ipaq+gps unit to enable the viewer to access located audio as they moved around the outdoor space. With Zoes piece the screen was hidden, in Dans the screen displayed images to draw the users attention to a particular location. Daniel Belasco Rogers description: As you walk down a street, do you wonder if it can remember everything

that happened on it? Can bricks and mortar really record sound vibrations from the past and if so would you be able to hear yourself? A description of this place as if you were someone else is an exploration into siting personal histories in geographical locations such as Queen Square, to form the tapestry of experience, and how the viewer can use the technology to peel back the city's layers, revealing those personal stories of first kisses and car crashes. Zoe Irvines description: This piece takes as its points of departure the filmic sensation of using a walkman and Queen Squares recent history as a venue for open air cinema

screenings. The viewer of the work navigates the physical landscape in which there are lingering fragments of film soundtracks which have both been shown there; the Matrix and Moulin Rouge. As the viewer/listener first walks around the soundscape it takes the form of an auditory archaeological dig but as the viewer moves further the sounds begin to merge and transform taking on ideas of DJ culture and plunderphonics. Multiplayer game experiment (May 2004) CitiTag is a wireless, location based multiplayer game Designed to enhance spontaneous social interaction Integrates virtual, gamespace presence with

physical Players tag players on opposite team and are freed by friendly players Urban space becomes a playground and everyone is a suspect. Fielded Summer 2004 Demonstrate DABs capability to send multimedia data alongside existing audio services. The data will complement the audio with: album images, interviews with the artists and interactive games. These will be triggered by the broadcaster.

Demonstrate conditioning of the audio by inserting downloaded sound clips at certain points in the playback. The sound clip that gets played could be chosen based on context provided by sensors, for example location. Add in a low bandwidth backchannel allowing users to provide feedback to broadcasters, for example to vote for their favorite artist or song. Add in a high bandwidth backchannel (possibly 802.11), making it possible to download content over the Internet. EG an advertiser could broadcast an advert that contains a link to their website. This could be

viewed within the confines of the GWR-branded browser. BBC Festival of Nature Walk Ran for one week in October 2004 Participants were provided with satellite navigation equipment, a small screen and a pair of headphones Multimedia content is triggered based on the users location

Content provided by local experts Active Print / I Can Read You Active Print started development in June 2003 I can read you game was demonstrated May 2005 Active Print allows camera equipped devices to read a barcode like symbol, then pull content from the web based on that

information I can read you was a team based gather the clues game using Active Print Conclusions Conclusions As first large scale experiment in Urban Computing, the Mobile Bristol project was a success. Project was broad in scope and tried to

explore all facets of Urban Computing While some aspects have been dated by changes in technology, most basic concepts remain sound Multi-user participation is far more prevalent in the Mobile Bristol project than most current applications Questions?
