Motivation

Proximity is at the core of the spread of

different innovative services.

IoT products and services, for example, take

advantages from proximity: virtual heritage,

advertisements, customer support, ...

Case study:

Exhibition areas like tradeshows were not

yet fully enhanced by IoT and proximity services.

Motivation

4

Motivation: proximity services

Proximity Based Services:

Software services that use relative

distance between a user and other entities.

Location Based Services:

software services that use absolute

position information.

Motivation

Example: emergency warning

system that advices citizens that

live and are present in a place

about a catastrophic event

Motivation

6








Example: advice when you

are walking near a famous

person

Example: emergency warning

system that advices citizens that

live and are present in a place

about a catastrophic event

Motivation

7

Analyze how IoT can improve proximity

interactions between all the involved

stakeholders of an exhibition area

(tradeshow)

Stakeholders

Exhibitors

Participant engagement:

• Provide products interaction

• Enhance meeting interaction (e.g.,

book a meeting)

Participants

Experience enhancement:

• Use available products

• Interact with other participants

• Benefit from smart meetings

Organizers

• Easily provide common services (e.g., storage)

o AllJoynTM framework: a

software framework that

enables proximity interactions

between devices and apps.

It enables direct interactions

between near devices

• Standard version: for non-

embedded devices, like

Android, iOS, Linux

• Thin version, for resource-

constrained embedded

devices, like Raspberry


Prototype

o AllJoynTM framework:

• User-products interaction

• User-exhibitors interaction

• User-to-user interaction

Conclusion and future work

Prototype implementation: users appreciated proximity interaction with

both other users and exhibitors.

Exhibitors appreciated the possibility of letting users interact with their

products.

User feedback demonstrates that our architecture (that combines IoT with

proximity-based services) improved exhibition experience

Future work:

• New implementation with more stable and complete framework

• New validation tests

Conclusion
