Learning Spatial Semantics

We have built a system that acquires semantics for spatial terms in a simple 2D world. Users can select objects and describe them relative to a landmark (here marked by a pear). For example, someone might pick the apple circled here and say “a little above”. The system uses spoken input processed through our speech recognition system.

On the visual side, we measure a set of language independent features that includes not only the obvious distance and angle measurements, but additional values indicating, for example, the shape of the landmark.Ôøº

… il semble aujurd’hui improbable que le fait de truver son chemin soit du à un quelconque “intinct” magique. Il s’agit plutot d’une utilisasion et d’une organisasion logique des indicasions sensorielles fournies par l’environment exteérieur. Cette organisasion est fondamentale pour l’efficacité et la survivance meme de toute vie sans entraves.

The initial idea

My idea is that of a learning system to explore the city using a mobile recording different parameters.
In my vision, the user can walk into the city with a group of friend. All of them have a mobile with special functions which allows them to track their position and defines landmarks that is reported in the virtual map of the city. In addition, they can define sections of the map just joining the landmarks of the map. I hope to stimulate, through this system, the comprehension of the city and the ability to “read” the map and build upon existing structures and sites.
For this reason I think that the advices of a professional urban planner can have a great value on the definition of the project. the following are some of the questions I need to answer in order to proceed into next step of development:
1. What are the parameters a urban planner have to consider while planning the city?
2. What kind of information you can gather while walking into the physical city you cannot get from the map (*important*)?
3. What are the key idea a urban planning student has to grasp in order to achieve the goal of the course?
4. What is the elaboration a urban planner does on the layout of the city in order to test hypothesis?
5. What is the common process for proposing a city expansion or redesign that a urban planner does to formulate hypothesis and to test them before formulating the final conclusions?

Meeting with Golay and Merminod

Meeting with Golay and Merminod

1. We need to improve the educational aspect of the project because there are no possibilities for the professional market.

2. It is important to design the system so that the location information is sent as part of the message and not provided by the telecom company. This is for the privacy issues.

3. We need to recast the idea to give more space to the activities done in the field rather than on the virtual. This will justify the real time purpose and the mobility at once.

–> Simulation
People using the system are simulating, are representing reality making a model, but at the same time, they are augmenting the reality through personal cognitive processes.

I need to find a mechanism – activity which allows people to collaborate while collecting data? What are the other activity you can do in the place rather than collecting data – counting cars – taking pictures – walking – observing the structure of the city.

justifying mobility

Meeting with Pierre:

There are three reasons for justify the mobility:
1. Physical experience while walking into the city which brings an added experience to the learning.
2. Finding special information on the site which cannot be simulated or incorporated in by any means. these information are not present on the maps of the city because too specialise to be part of a previous study.
3. Reporting virtual information from the virtual world into the physical world. For example, exploring the lost city is just one of these examples because it allows to follow a street that doesn’t exist any more with the physical experience of bumping into buildings.

One of the possible solutions is to use the specific information recorded from the physical position to solve something in the virtual and the obtained outcome to be the pointer to another physical position (next move).

About urbanSimulation.com

Launched in June of 2002, urbanSimulation.com fills the void for an independent source of information specifically addressing urban simulation technology.

Most resources on the web today, has some sort of affiliation with a particular vendor, therefore a need arose for a truly independent place for researching information and discussing topics concerning urban simulation.

There is more than one way to simulate urbanism. With that in mind urbanSimulation.com is open to and welcomes a wide range of methodologies and approaches for simulating the built environment.

urbanSimulation target specifically all the resources related to the graphical display of simulated cities, GIS, historical studies, etc.

Dreamhaus: build your imagination

The problem of our epoch is the problem of the house
— Le Corbusier (1919)

DreamHaus is a third person adventure / design game. DreamHaus uses architecture as an entry point for learning AP-level mathematics, engineering, and physics material. Players examine virtual architectural sites (such as the Tokyo Olympic Stadium), solve physics and engineering-based puzzles, and complete architectural design challenges using the game’s design tools. Players may also participate in a web-based community surrounding the game, submitting their designs, viewing others’ work, or offering critique on designs.

DreamHaus draws on the artistic allure of architecture and romantic history to make Engineering and Physics accessible to a diverse audience of players. Players explore fantastic virtual buildings, solve thought-provoking Physics and Engineering puzzles, manipulate virtual Engineering Systems, share their work in virtual communities. These game practices have proven to be successful with non-gamers in games such as Myst, SimCity, and The Sims. DreamHaus capitalizes on games’ ability to represent buildings as systems, and allows players to learn through manipulating these systems. DreamHaus is grounded in David Perkins’ Teaching for Understanding a pedagogical framework that is designed to foster deep, intuitive understandings of phenomena by providin learners multiple entry paths into understanding and performance-based modes of expression.

designing a city

if you wanted to design a city, what rules would you make?

The effort to maximise one’s wealth through personal profits and land speculation creates all sorts of problems in the modern city, and that is difficult to administer such a city.

Should decisions affecting all the players be made by one of them? Where to place major buildings, where to locate city services, and what kind of services to provide should be decided by everyone.

the anatomy of sprawl

Hudson, Ohio: the anatomy of sprawl

This article describe the morphological approach to the urban study of a city, establishing a system of analysis that breaks the physical city down into fundamental elements that are found in all cities. Sveral steps are taken to analyse the city:
a. study the population (and growth)
b. locate urban core and village center
c. define land use (functional study, classifying areas and corridors by their use)
form is different from function
d. describe land subdivision (blocks, districts, tissues, regions)
e. proceed through an historical comparison
f. arrange the components of the city into broad groups (site, buildings, objects) this is related to the order of endurance of components.
g. analyse the cadastral map where two broad groups of spatial ordering componets (paths and plts) can be thought of as a “checkboard” upon which the physical elements of the city are composed and built.
h. compare the different layers representing these different components.
i. explore the topography of the site.
The author sketches an operative approach while planning the urban expansions and redesign according to each particular tissue . For the elastic tissue, there is no proper methodology, so, in this sense, there is space for experimenting new approaches, trying to mix phisical walks with traditional approaches.

————————————————————

Most of the tasks described above requires the following cognitive tasks:
1. comparison
2. build exemplar units
3. layering
4. define transitions points

Is it possible to incorporate these tasks in a collaborative game?

1. The gaming board is the cadastral map
2. The size of the city should be determined by the number of participants
3. The goal is to maximise the citizen’s wealth
4. [LAND] Businessman and factory owners expect to collect profits on their business which can be connected to the land value which will result in increased profits.
5. [PEOPLE] if people have to travel a lot to reach their destination they loose their work efficiency
6. [GOVERNMENT] one or more players represent the city government, they have to act in agreement. Also the government can be elected with secret ballot.

MapTribe shaping up

MapTribe is moving towards the direction of tool for supporting urban planning. During the past few weeks we sketched possible applications for this technology:
1. place a landmark_ define zones, track the geometry of a place.
2. contextual alerts_ social navigation.
3. additional information_ Geographical Information System (GIS) -> Local Observation: data you can observe directly and that you cannot find elsewhere.
4. Mix physical and conceptual experience: physical experience is an important added value to the cognitive experience.
5. Movement tracking.

An interesting idea for the scenario is to ask students to follow a street that doesn’t exist any more. They can follow the street using the historical map on their mobile and they can leave landmarks in the new map of the place for comparing the the maps but also for understanding physically how the landscape was modified during the years.

Another interesting activity is related to the making students stepping back from the map and encouraging them to take their perspective:

For this purpose we envisioned an activity of taking pictures of the facade of buildings and relate these information to the gps position and send back to the server for building an interactive map of the city.

I realised that a game is the perfect script/activity to support both exploration/collaboration and learning practice. So, the proposal needs to be rewritten trying to:
1. building a learning/game scenario
2. merge the game design with the learning design
3. give an idea of possible feature/interaction on the map
4. synthesise the key ideas of the scenario

Today I started reading the book by Wilson Forrest titled: City Planning: the games for human settlement.
This book target precisely the idea of learning the urban planning through games on tridimensional game boards.

Urban planning

Study more deeply the field of urban planning to justify the project and to build a better scenario.
Did some biographical research on the subject.

I have to find a way to create a conceptual framework where the students can compare their work and activate a cognitive process above it. For example dividing in groups and comparing the results at the end.

[analysis - actions] ——–> [synthesis - cognitive process] ———> [new step - starting over with new hypothesis]

What students need to understand from the course? What are the key ideas?
How do they usually achieve these ideas? What are the tools usually used to grasp the ideas?
Is it possible to use technology to support the cognitive processes o these topics?

> meta-cognitive / epistemological <
How these ideas are related? Is there a structure among these ideas? Are there ideas which can be considered more prevalent on the others?

cartography – semantic maps – geometrical relationship – urbanism

restructurig the proposal

I need to restructure the proposal following the new idea: ClickTribes / MapTribes_

1. Restructure the scenario placing a picture + a map of Lausanne. for the interaction design.

2. Rationale: (1) Mobile Learning in Urban planning; (2) territories for Urban Tribes.
-> answer the question: Why would you pay for this project?

3. Research framework
. Questions
. Method
. Similar work
. Technology
. Planning and Budget
. CRAFT

4. Tools to understand the city / to decompose the map
5. Differencies with SimCity: - there is no dynamic aspect

6. possible application: 1- bridge to SimCity
2 – to do something else

Lhvpu

Alexandre Pilloud is in charge of the development of the e-learning site of the course in Literature and History of the Ville in the Urbanist context: lhvpu.epfl.ch.
Some of the key ideas the students have to learn while studying the urbanist development of a city are connected to the roads, idrographic map, parcels.
