Bart and Evi have planned a city trip to Brussels. Both of them have never been in Brussels so they do not quite know what to expect. A friend of Bart, who has lived and studied in Brussels, gave him some suggestions, such as a visit to the Marollen and Sint-Katelijne.

Bart would like some additional information on Brussels and thus starts up his computer and opens the internet browser. He enters 'bezienswaardigheden Brussel' as query in Google.

On top of the listing with the search results appears 'Top 10 bezienswaardigheden van Brussel'. Bart goes to the website and reads the 10 suggestions. They seem very interesting so Bart prints the webpage.

One of the top 10 curiosities is the Marollen. The website claims it is a sociable and authentic district of Brussels. Still Bart wanders if it would actually be worth a visit. So Bart decides to open the 3D city application and enters 'Marollen Brussel'.

Introduce POI's of Tele Atlas, check with Tele Atlas what kind of POI's they have, for example Marollen?

It is strange to connect a district to a POI because it is not a point.

It is important that

the search activities of the user are ideally not saved/stored, or at least only for a short period or else you will run the risk of profiling.

Bart now sees the Marollen in bird's eye view and notices that the district is near to the Palace of Justice, which is enlarged.

Indicate important monuments: colours, arrows, red line/contour around a building. EDM/Androme agree that the starting point/screen should be bird's eye view/2D map. Tele Atlas cannot provide satellite images.

Emphasizing important

buildings/monuments in bird's eye view could work.

Since recently Tele

Atlas has a deal with BLOM so as from Q1 of next year they will probably have satellite images.

Bart descends to the street level and virtually walks through the Marollen district. He did not know there were so many antique shops in this area. This will definitely interest Evi. Bart puts the district on his to do/see list.

It will not be possible to see what is installed in a particular shop, but by means of the POI information of Tele Atlas you will be able to identify the type of shop. It will also be possible to distinguish houses from shops, for example introduce symbols of restaurants.

It might be useful to propose a typical walking route through the district or else the user might easily get lost and go outside the district.

You can combine

virtually visiting the Marollen with entering a building that is technically feasible. Can you print the information and take it with you? On the spot, you should be able to ask for more information about a building with your PDA when you are standing in front of the building.

POI information of

shops: within the MOBVIS project the university of Slovenia developed a mobile vision application: if a user takes a picture of a building, the information will be send to the server where the 3D model is annotated and which is linked to the POI information. As a result the user will receive information on the picture he took on his mobile display. It would be interesting to contact Prof. Ales Leonardis: link existing components of new mobile applications to URBAN.

Bart's friend told him there are a lot of excellent restaurants in Brussels. So Bart decides to click on the feature 'Top 10 Belgian restaurants' in the 3D city application. Ten buildings colour green in the bird's eye view of the city centre.

Experiment with what kind of indication the user prefers, for example coloring, arrows, ... A link to a webpage with a top 10 of Belgian restaurants is easier than integrating it into the system/software. In case of the latter, you will need someone who constantly updates the software. In addition not every tourist will be interested in a top 10 of Belgian

restaurants, but might prefer a restaurant that offers reasonable prices.

Bart double clicks on one restaurant and descends to street level. He takes a look around. The restaurant, called 'In 't spinnekopke', looks very cozy from the outside and is located on a pretty little square. Bart clicks on the restaurant and the following message appears: "In 't spinnekopke welcomes you every day of the week, except on official holidays. Go to our website for some additional information and to consult our authentic Belgian menu card."

The idea is that a restaurant could buy its own virtual restaurant and uploads information. The feedback can be faked in the demonstrator.

Link to website of restaurant is good idea. You can charge restaurants to upload their link into the system.

Is this a sort of

advertising?

Bart selects the note icon that is attached to the restaurant and receives the most recent restaurant reviews of former visitors and a general score that is based on all the reviews.

EDM/Androme are not that enthusiastic about integrating this idea because it is linked too strongly to a previous project called A4MC3. An option could be to integrate a link to resto.be

Tele Atlas thinks it is

a good idea to show the scores of a restaurant.

Evi and Bart will take the train to Brussels to avoid possible parking problems. Bart marks the central station of Brussels as starting point on the 3D city map and some places he has put on his to do/see list. Now he clicks on 'simulate route'.

Predefine some walking routes, not make your own walking route. As starting point take the most obvious places like central station. Copy walking routes of maps of Brussels tourist centre.

It will be interesting

to plan a route, from A to B that takes some criteria the user entered into account. The added value will have to be that the route is better visualized than all the other existing route planning applications.

The Urban Maps of

Tele Atlas, their pedestrian maps, have certain features like shopping street, tourist street, ... and with those attributes tourists can make their own loops. Linde thinks that Tele Atlas has such features for Brussels. Reuse existing features of Tele Atlas as much as possible.

He automatically walks out of the train station, crosses a big street and follows a descending street. He arrives at a big square which is marked with 'Grote Markt' in grey letters.

Are POI's, will be possible to show the names. All the POI's on a route should be marked.

Squares are not

POI's, but have an address label.

Bart clicks on the event icon that he sees on the 'Grote Markt' and receives the message: "Every saturday of July free jazz concert on

the Grote Markt". That is good to know.

Will be possible, can be faked by the demo. Event POI will be made by EDM by themselves. Is important for tourism.

It might be complicated to keep this information up-to-date. Maybe it can be linked to a webpage where this kind of information is kept up-to-date so you can download the information of current events.

GA's mobile mapping data can also be useful for the municipality. For example to assess if there is enough space for the stage of the jazz festival, if certain trees are too big, ...

It might be

interesting to make a link to the culture web of Belgium (cultuurweb.be). You will have a strong case if you would link all the cultural events to POI's. Contact cultuurweb?

Evi has offered to search for a nice hotel in Brussels. She opens the internet browser and goes to Tripadvisor.com. She clicks on 'Hotels and accommodations' and enters Brussels as city. Evi carefully looks at the most popular hotels and reads the reviews of former guests.

Hotel Bloom receives overall positive reviews and seems very trendy. Yet the most important requirement for Evi is the central location of a hotel. Thus Evi opens the 3D city application and enters 'Hotel Bloom Brussels'.

Indicate distances from the hotel to city centre, indicate different points/locations and distances in bird's eye view/fly distance.

A lot of fancy hotels already offer 360° images of the interior of the hotels by means of QuickTime Virtual Reality applications. Could be interesting to integrate. Is does not always need to be 3D data.

Evi now sees the hotel colored green from bird's eye view. She immediately notices the proximity of the royal palace and the central station, which are both enlarged, so the hotel is well located.

Not enlarged, but marked. Names of POI's are enlarged.

Enlarging buildings might be complicated. You would have to draw the enlarged building over the other buildings.

If the user wants to

enter the hotel, it becomes more complicated. When the 3D model of an hotel dates from before a reconstruction this will not stroke with the reality anymore. This could cause a problem.

Even though the central train station is not that far away from the hotel, Evi does not want to walk the end with all her luggage. That is why Evi goes to bird's eye view and selects the central station as starting point and the hotel as end point. Now she clicks on the feature 'public transport'. Within a few seconds Evi receives the timetables of the busses and trams that connect the two locations.

Provide links to website to De Lijn, NMBS, MIVB and enter the queries by themselves. Are going to look up if this is possible.

Providing links to public transport web pages would be the easiest solution.

Recently Montréal is included in the Google Transit feature of Google Maps. So one can indicate 2 locations and request a public transport route description.

Public transport in

3D is a sensitive topic. Tele Atlas is involved in a project with De Lijn, NMBS & MIVB. Making a link to their websites at all the stopping-places is easy, but entering their database to calculate the route and insert this information into the 3D environment is more difficult and the focus of another project.

Once arrived at Brussels, Bart suggests they first go for lunch. What was the name again of that authentic Belgian restaurant on that pretty little square? And where is it located? Bart quickly takes out his PDA and opens the 3D city application. He clicks on 'Top 10 Belgian restaurants' and again sees the 10 restaurants colored green.

It will be the future when GPS works better in a city and there is wireless everywhere. iPhone has good GPS but has to be tested. Test accuracy of iPhone in Brussels.

GPS might

sometimes lose its signal in a city, but Karel has overall positive experiences with his GPS in the city.

Geographical

locations cannot be stored, unless the location is necessary to invoice. So as soon as the user has received the information he asked for at a specific location, the location needs to be erased.

Tele Atlas tested a 3D model of Rome on a Mio device 3 years ago and only had little loss of signal. You don't need wireless internet if your data is local. Your 3D application can be locally installed, you can download it once at a train station or airport but you don't need it everywhere on the road. Other information can go through GPRS.

The GPS receiver of Bart's mobile phone locates Bart and Evi's current position. The 3D city application generates a route that will bring Bart and Evi to the restaurant.

Route planning is complex to implement, switch to google maps in the iPhone.

Tele Atlas thinks it's

strange that navigation is disconnected of the 3D model: the user should always see its position in the 3D model. For 3D navigation it would be interesting to contact the project Mona 3D in Germany: develop special algorithms to navigate efficiently in 3D models on mobile applications. For Tele Atlas it is important that 3D and navigation are never disconnected from each other. The prototype has to be on a mobile device to be relevant for Tele Atlas. This mobile device needs to contain a compass function and indicate the direction the user looks at.

Annex 6: Input of project partners on user scenario real estate

User Scenario: Real estate EDM/Androme IMEC VISICS GeoAutomation AGIV ICRI Tele Atlas

Bart and Evi are searching for a spacious family house outside the busy city centre of Brussels. For the last few months, Bart has been browsing Immoweb.be. As a daily habit, Bart starts up his computer and goes to Immoweb.

Bart enters his personal criteria, asks to only show the updated/new properties and starts the search.

In the following listings of properties that match the entered criteria, the picture of the façade of a house in Vilvoorde catches Bart's eye. So Bart clicks on the listing display in question and receives additional information on the property. Bart closely examines all the property pictures. The pictures look promising so Bart also reads the short description of the property.

Yet Bart is also interested in the location of the property. He clicks on 'ligging' in Immoweb and receives a road map of Vilvoorde with a small balloon that locates the property. However this does not offer Bart a lot of help since he does not know Vilvoorde that well.

So Bart clicks on 'ligging in 3D' and receives Vilvoorde in bird's eye view. The position of the property is indicated with a small balloon.

EDM/Androme agree that the starting point/screen should be bird's eye vies/2D map. Tele Atlas cannot provide satellite images.

Will this tool play a

part in the purchase of a house or will it only be informative? In case of the first option, the tool will be subjected to the contract law and everything the user sees in the 3D model will have to correspond with reality.

Tele Atlas refers to the deal with Blom concerning the satellite images. It is also important that the prototypes allow to switch between different views: 2D, 3D, aerial, bird's eye.

Bart notices that the property is nearby the church of Vilvoorde, which is enlarged. He remembers that the church is located next to the shopping street where he and Evi sometimes go to. Now he can locate the property within Vilvoorde.

Enlarging buildings is not possible, coloring for example is. Names of POI's can be enlarged. Experiment with what kind of indication the user prefers, for example coloring, arrows, ...

Evi and Bart want to get away from the noise in the city centre of Brussels. Thus Bart looks at the distance between the motorway and the property. The property is located perfectly: far enough from the motorway to avoid noise nuisance and close enough to go to work.

To assess the

distance to a motorway you need to know the location of motorways. Karel assumes Tele Atlas has such maps.

When buying a house, 2

factors are important: the sight and the noise. People want silence and a nice view. There already exist algorithms that calculate the decibels by means of the proximity of motor ways, the hight of buildings, the wind direction, etc. The same applies for sights, what is the periphery that you can see? Relevant research has been conducted in the

Netherlands. See Springer book 3D conference at Delft in 2006: contains an article of a researcher that used 3D models for sound algorithms. Such tools would give 3D models an added value.

In contrast to Bart, Evi prefers to take the train to work. So the proximity of a train station would be an advantage. So Bart enters 'train station Vilvoorde' as query in the search box.

Introduce POI's of Tele Atlas, but check with Tele Atlas what kind of POI's they have, for example train stations?

Tele Atlas has 3D landmarks

of special buildings, but train stations usually do not belong to that group. SMIT can have the 3D landmarks and 2D urban maps for Brussels.

The position of the train station is indicated with a small balloon. The distance between the property and the train station is approximately 1 kilometre so Evi will love to hear that.

Bart now descends to street level. The façade of the property and its front garden seem well looked after. The houses of the neighbours also look very pretty.

Only possible to see through omni-directional video, not in the 3D world that is not detailed/realistic enough.

Omni-directional video would be more suited to explore the façades of a property since the 3D model is still quite simple, not detailed enough.

Solution for insufficiently detailed data: make the images that are recorded in all directions by GA's van available on the internet. Then the user will have highly detailed 2 pixel pictures of the property and its surroundings on street level.

The more details and information and the more user friendly, the better.

For the MOBVIS project Tele

Atlas made a prototype where they made their mobile mapping data available through a web server and after entering the street name and house number you immediately see the façade of a house. You have the full 360° so you can indicate what you want to see. SMIT could maybe ask GeoAutomation to offer such images since it's their core business. BUT, privacy issues: fade the faces and license plates.

Bart takes a virtual walk through the street of the property. He comes across a little playground, the children will love that. At the corner of the street, Bart passes a bakery and GB Express.

It is important to keep

the data up-to-date because for example supermarkets come and go and a new big supermarket could cause shadows in the property's garden. On the other hand, people will only use the tool for preselection and will not buy a property before visiting it in person. A playground might be difficult to recognize in a 3D model because with all its different structures it is difficult to reconstruct. It might be possible to automatically detect particular logo's of companies, like Carrefour.

If you want to know

where there is a park, shop, pharmacy, etc a 2D map can give you an overview. 2D should be combined with 3D.

For Tele Atlas the link

between position & 3D and navigation & 3D is very important. Users should always be able to position themselves

Bart walks back to the property. He notices that the property does not have a garage, yet the street is broad enough to park cars on both sides of the street.

The question is

whether it is allowed to park in a street. But you could introduce artificial cars to indicate that you can park on both sides of a street.

At the moment, Bart still has one question: is it a busy street? So he looks around in the street and notices a traffic sign that indicates a maximum speed of 50 kilometres per hour. That is already a good sign.

So he clicks on 'omni-directional video' and chooses 6 p.m as time of the day. An additional screen appears and shows the 360° images that are recorded in the street of the property at 6 p.m. The street is not jammed by traffic, definitely a big difference with their current place of residence.

Integrate the switch between the 3D world and omni-directional video in the demo.

This requires to be

present at every part of the city at 6 p.m to capture the 360° images. You could say between 5 and 7 p.m, but this still means you need to be present at many places in a short time. The images can also be misleading, it might have been busy in that street at that moment because of reconstructions nearby.

Omni-directional video can also be used to explore the

neighbourhood and even for a virtual tour inside the house. Image based rendering could also be interesting: generate a virtual camera by linking a lot of pictures to one location that the user can steer in different directions. VISICS has experience with this, but not the scope of URBAN.

If the

omni-directional video is used as a sales argument and not solely as an information tool, than it becomes risky. In that case if the street did not look busy on the ODV, but actually is busy in reality, you have a legal problem.

Bart has seen enough. The property looks really interesting so he immediately dials the telephone number of the property owner that is mentioned on Immoweb to make an appointment for a home visit.

Annex 7: User scenario tourism adjusted

User Scenario: Tourism Previously Adjusted because:

Bart and Evi have planned a city trip to Brussels. Both of them have never been in Brussels so they do not quite know what to expect. A friend of Bart, who has lived and studied in Brussels, gave him some suggestions, such as a visit to the

One of the top 10 curiosities is the Marollen. The website claims it is a sociable and authentic district of Brussels with a beautiful church called 'Kapellekerk'. Still Bart wanders if it would actually be worth a visit. So Bart decides to open the 3D city application and enters 'marollen brussel'. Unfortunately he does not get any useful search result.
