Introduction

• Our objective is to study a new approach of mobile web andlocation-based services (LBS) for communication / collaboration.

• Classically web communication is world wide: an user canClassically web communication is world wide: an user can communicate (access, consult, update,…) the information which is located world wide.

• At the apposite, tools like Follow-me (experimented at Interact 2003) is working on the on the basis of geographical proximity of actors, who can be detected by the locator and each actor is informed on de proximity of his “friends “.

• Our approach is based on a physical hot spot serving as an pp p y p gaccumulation point; a hub for thematic and social collaboration.

• Different actors can consult, publish or exchange information in relation with the location materialized by the hot spot.

Communication / Cooperation • A taxonomy of cooperation situations was proposed by Ellis et al. [1]

who identified local versus distant and asynchronous versus synchronous working conditions. y g

• The next step was to take into account the location of actors i.e. predictable or unpredictable [2].

• At the moment we have a large number of solutions, from asynchronous (in the form of e-mail, SMS, MMS) to more or less synchronous as with ICQ, …

• From a device point of view, desktops or laptops are not anymore a unique kind of device, more mobile devices such as TabletPC, q , ,PDA, and smart phone, called wearable or handheld computers, are being used more and more.

• In web-based cooperation the location of actors can be world wide and more or less dynamic as are facebook or twitter.

Case study

• For us the communication / collaboration is mobile and contextual.contextual.

• In our case study it is based on a bus shelter as a location hot spot and is transportation and local community social life cooperation oriented.

Eight basic communication / cooperation situations:

1. Global interaction between initiator actor and www server.2. Local interaction between initiator actor and hub server.3. Local interaction between initiator actor and hub server with

propagation to final actorpropagation to final actor.4. Local interaction between initiator actor and hub server with explicit

consultation by the final actor.5. Local public advertising sent by the servers or initiator actor to the

Hub Public Screen, with possible propagation to final actors (push).6. Local public advertising sent by the servers or initiator actor to the

Hub Public Screen, with possible collection by final actors (pull).7. Local semi-public information sent by the servers or initiator actor

to the Hub Public Screen, with possible collection by final actors (pull)

8. Local private information sent by the servers or initiator actor to the Hub Public Screen, with collection by final actors allowed by received access code (pull)

Transportation oriented Hotspot Communication / Cooperation

Main services:• Deliver highly detailedDeliver highly detailed

transportation information• Special requests (cycle or

baby carriage, elderly or disabled passengers …).

• Rapid or snail transportation, according to a majority passenger destination.

• Car sharing or hitch-hiking

Neighborhood social life oriented Hotspot Communication / Cooperation

Main services:• Local animation during the

waiting period for adults and childrenchildren

• Transportation intermodal information

• Shopping and tourist information, cultural and sport activities

• Theatre, sport games, community associations meetings

meetings• …

• Lockers for parcels to be sent and received in order to manage home and office-off of an addressed person. The locker has a sharing ID access mechanism which ismanaged by the hotspot. The sender can ask for an ID, which will be used to deposit the parcel, and the distribution service will use same ID to take the parcel and vice versa for the distribution of parcels.

Information exchange

• Information exchange between a large public screen and personal handheld devices by QR-Code to appropriate, personal and confidential exploration and treatment.

Main services:• Local information such as

just in time shopping advertising from local shopkeepers, bakers or butchers

• Neighborhood exchange of used clothes or appliances

• Private information

Final discussions (1/2)• Bus shelters in urban locations and on busy traffic routes are often

provided without charge by companies such as JCDecaux, Clear Channel Communications and CBS Outdoor in return for valuable out-of-home advertising rights In this way economicalout of home advertising rights. In this way economical considerations can be integrated into this global negotiation.

• Another important aspect is related to prevention of vandalism and degradations. Naturally this is an important aspect mainly in certain county areas and districts. The solution is not easy but can be oriented to different approaches: physical protection, appropriate technical and technological solutions such as with no large screenstechnical and technological solutions such as with no large screens and only individual devices on which the information is exclusively displayed, and so on.

Final discussions (2/2)

• Another important problem is naturally related to the acceptability of such a system, in its different aspects which are more or less intrusive in an actor’s private life [15] Of course two excessiveintrusive in an actor s private life [15]. Of course, two excessive attitudes are to be eliminated: nothing and everything.

• We expect to carry out appropriate acceptability studies in relation with which different prototypes on which we are working at the moment will be experimented.

Conclusion and perspectives• We have presented an original mobile web and location-based

services for communication / cooperation situations characterized by a contextual hotspot.

• It allows to the actors located worldwide but having a particular location point of interest, to organize their communication / cooperation in relation with this hub.

• We have described a generic view and its adaptation to a situation related to transportation and neighborhood life.

• We are at the moment creating a first prototype in order to be able to appreciate its utility, utilisability and acceptability with the respect of privacy.
