Here is the sales pitch from citysense. A system for gathering and representing real time city data from San Francisco. A nice idea for a company.
Quoted.
Citysense is an innovative mobile application for local nightlife discovery and social navigation, answering the question, “Where is everybody?”

Citysense shows the overall activity level of the city, top activity hotspots, and places with unexpectedly high activity, all in real-time. Then it links to Yelp and Google to show what venues are operating at those locations. Citysense is a free demonstration of the Macrosense platform that everyone can enjoy.

Instead, it evolves searching to sensing. Citysense passively “senses” the most popular places based on actual real-time activity and displays a live heat map.
Location data is everywhere. Cars, buses, taxis, mobile phones, cameras, and personal navigation devices all beacon their locations thanks to network-connected positioning technologies such as GPS, WiFi and cell tower triangulation. Millions of consumers and businesses use location-enabled devices for finding nearby services, locating friends & family, navigating, asset- and pet-tracking, dispatching, sports, games, and hobbies.

These forces have lowered the cost of technology, ignited interest in location-enabled services, and resulted in the generation of significant amounts of historical and real-time streaming location information. Sense Networks was founded on the idea that these datasets could provide remarkable real-time insight into aggregate human activity trends.

Macrosense employs patent-pending technology to learn from these large-scale patterns of movement, and to identify distinct classes of behaviors in specific contexts, called “tribes.”

Once it’s known which tribes are where, by sampling the distribution of tribes at any given place and time, it’s possible to understand what it means when a user is there at that place and time.

For example: rock clubs and hip-hop clubs each retain distinct tribal distributions. When a user is out at night, Citysense learns their preferred tribe distribution from time spent in these places. When that user visits another city, they see hotspots recommended on the basis of this distribution and combined with overall activity information.

Users who go to rock clubs see rock club hotspots, users who frequent hip-hop clubs see hip-hop hotspots, and those who go to both see both. The question “where is everybody like me right now?” is thus answered for these users – even in a city they’ve never visited before.

Citysense is an application that operates on the Sense Networks Macrosense platform, which analyzes massive amounts of aggregate, anonymous location data in real-time. Macrosense is already being used by business people for things like selecting store locations and understanding retail demand. But we asked ourselves: with all this real-time data, what else could we do for a city? Nightlife enhancement was the obvious answer. This release is just a test, and we’re interested in your feedback on how to make the application better. You’ll find a feedback button in Citysense.

Principles…

People should own their own data
People should have full control over the use of any data that they generate. All data collection should be “opt-in,” and users should be able to easily remove themselves and their data from the system without questions or hassle. The system doesn’t “remember” a user for later, but completely deletes data at the user’s discretion.

People should receive a meaningful benefit in exchange for sharing data
Meaningful benefits include compelling applications to help manage life better, or personalized services based on anonymous learning from “users like me.” People should be able to enjoy the benefits of these services simply in exchange for their data.

We’re looking for additional common good uses of aggregate, anonymous location data. If you would like to submit a project for consideration, please contact us at ….

From my Sensity projects.
Citysense…Sounds like sensity backwards….Various types of data can be re-imagined within the context of city space and the environment. This includes pollution data recorded via sensors in the street, to create audio acoustic files expressing the pain and suffering of the air as it pollutes. Weather and forecast data, acquired via weather station equipment; this can be used and can create ambient soundscapes and morphing visualizations as the wind shifts direction or the rain increases. Noise monitor levels, and noise maps , create a symphony of true urban sounds that can be used to make sound reactive sculptures. The patterns we make, the forces we weave, are all being networked into retrievable data structures that can be re-imagined and sourced for information. These patterns all disclose new ways of seeing the world. The value of information will be a new currency as power change. The central issue that will develop will be the privilege and access to these data sources….
I like their pitch about owning their own data, couldn’t agree more in fact all royalties should be shared. Its not just about privacy its about ownership. Once you enter the grid you body is now externally giving away data and information. Companies are now rushing to harvest this information , ( information services) making new products for mobile devices. I think we are going to see a lot of this.

“Gallery” by Stanza, is a dynamic public sculpture viewable over the internet.

"Gallery” by Stanza, is a dynamic public sculpture viewable over the internet.

“Gallery” by Stanza, is a dynamic public sculpture viewable over the internet. Gallery describes the space, in this case the upper gallery in Plymouth Arts Centre, England. Made during an artist in residency project in situ in the gallery space during feb 2008.

The gallery interior has been made virtual and placed online. “Gallery”, is part of a series of process led experiments in data visualization within the context on an art gallery. This is an experimental engagement with data in the art gallery using sensors and CCTV. Stanza asks , “what happens during the process of visiting the gallery as a dataspace”; ie what happens to the gallery and what do the visitor do?

The sensors are used as real time recording devices to gather information about the sensory behaviour of the real space. The gallery becomes the artwork formed by the emergent real time data in the space.
The gallery laid bare as a work of art. Gallery proposes that the data is art. The art is a real time flow of the things around us that allow our senses to invoke understanding. The gallery space becomes the art described by the shifts in light, temperature and noises in the space over time.

Surveillance artworks: experiments with realtime images.

Stanza artwork: Live CCTV online remixed in real time. 2004

Projects with tangible outcomes for the mobile infrastructures. Using CCTV to create emergent artefacts and new ways of seeing the city. In the UK there is one CCTV camera for every 14 people. If you are in London, you could be caught on camera up to 300 times a day. Westminster City Council in London have come up with a solution – CCTV cameras without wires, which broadcast their pictures back to base using the council’s new wireless network. The advantage a wi-fi network camera is the mobility.

The pilot scheme uses five discreet cameras to monitor people’s comings and goings in Soho Square. Wireless CCTV cameras make it easier for more and more cameras to be installed.

“Within the Soho Square we have a network of wireless LAN bridges providing blanket coverage throughout the square,” said Tim Hearn of Cisco Systems which is providing some of the technology. “Down the narrows streets, Greek Street and Frith Street, we have Wi-Fi pointing down those streets as well so they give us coverage down there.” So that’s a network of wireless LAN devices that we then plug into CCTV cameras, we provide access to mobile workers that will have laptops of mobiles working with them, or maybe some specialist devices. “We’re also linking into noise monitoring devices or other sensors,” he said. Sourced from the BBC website.

The city already has a recorded source of data, cctv is everywhere. Using data from cctv, artists can bring the outside inside. Selected feeds are collected from around the city in real time. These real time images can be fed into software systems where a series of specialised channels rework these images. The channels are always on, and always changing, a constant view of any city or environment evolving around the clock.

I have made a system or art project called ccityv which uses specially created software and technology to randomly engage any camera globally. The system can grab images from any source.

I have to extend this to network cameras in the Bristol area. It is now possible to go further and get everyone in Bristol to tell us where webcams and cctv systems are; we could also set up some of our own. We can then grab all this imagery and edit it rework it and manipulate it inside the software.

Using pdas we can also send users to find the cameras to be recorded and re-engage with the world of surveillance. This system can capture portraits to monitor, and we can use it to tell stories and narrative in the street that can come into the ccityv project. This allows a process to start whereby we can get the outside inside and the inside outside. Data maps can be set up using the mobile Bristol software so that users can find these cameras and put themselves in the pictures. Then when it is updated you would be updated into the archive online. So the public can have all sorts of fun with this. The public can use cameras to make narratives, take portraits, subvert the surveillance process etc.

My system is online and can be engaged with in the everyday use by anyone. Most importantly it is inside the gallery projecting onto display devices. Note this is in real time, it is also online (see urls below); see the date and time stamp on each one. Also if a camera does not load please wait and a new one will be found immediately. Sometimes cameras go offline. The first image to load is a ‘dummy’ image.

Sensity in Italy Festival at Share IT. The art of environmental data

March 21st, 2007

ddcPIEMONTE_SHARE_FESTIVAL | TORINO, 23 – 28 GENNAIO 2007: From over 200 submitted works, an international jury shortlisted six works that were exhibited at the festival, from which one prize winner is selected.

Sensity was selected but they just set up a projected version rather than the live sensor network. Like with many other festivals, there is one prize only that is not tied to a specific technology or genre but rather to their combination and to the expression of ideas.

A series of artworks based on connecting city spaces. The results are visualisations and sonifications of real time spaces using my own wireless sensor networks and environmental sensor technologies.

Sensity artworks are made from the data that is collected across the city. The sensors interpret the micro-data of the interactive city or responding city space. The outputs from the sensors networks then display the “emotional” state of the city online, in real time. The information is also used to create offline installations and sculptural artworks. Several artworks (sonfications and visualisations) have been made connecting up space and cities.

All the artworks in this series by Stanza use data from the real time environment. A new city experience results based on the mash up meta data from these multiple cities streams. Sensity leverages these real time data city streams and represents it online, showing the life of the system, opening up the system, and the publishing emerging changing bahaviours of the space.

As all things becomes connected and networked, my concept will be become a system that senses not just the city but the whole world. Eventually sensors will be linked to give a real time global visualization. ~ Public domain data resource for art and environmental monitoring.
