D2.2: Set of use cases and scenarios

Title: SCENARIO: ENJOY A BAR IN 2012

Scenario: Enjoy a bar in 2012

What does a bar in the future look like? This scene (see , image source: [Beslay et. al, 2005]) helps to describe the features of such bar.

Figure 9.4‑: A scene in a bar in 2012

First of all at both entrances, we can observe electronic devices (e.g. for the detection of new customers or the transmission of information); on the wall a special TV; at the bar an adaptive screen and personal electronic devices (e.g. a PDA) for some customers. The Ambient Intelligence environment of the bar is symbolized by the dashed oval - this determines the space in which communications are enabled and all devices can interact. 

The scenario is composed of four moments as depicted in the schematic view below (see ). The customer (i.e., the user of the AmI environment) enters into the bar, enjoys a moment at the bar, he is fortunate enough to have a chance encounter and finally, he pays for the drinks.

Figure 9.4‑: Schematic view of scenario

Case Study 1: in his city

Entry into the bar: The customer declares his preferences (using his PDA) and activates his availability to meet a friend (Thus, the following data are transmitted - to the adaptive screen for example - : his favourite drink, language etc., his user specificities, e.g. prescribed medication and list of friends.)

At the bar: Barman: do you want a cappuccino? (the transmitted favourite drink). The adaptive screen shows also him the soft drinks option (it knows he cannot have alcohol because of his medication).

Thanks to his electronic device he “watches TV in the language of his choice (preference)”. (more precisely, he listens to the sound in the language of his choice through his PDA and the corresponding image is displayed on the TV screen). 

Chance encounter: An alarm notifies him a friend has arrived.

After a nice conversation with his friend, he decides to leave. 

Payment: He chooses whether to pay with fingerprint mode or with RFID (Radio Frequency IDentification) card from local account.

Case Study 2: foreign country

Entry into the bar: He declares his preferences. A temporary account is opened.

At the bar: The adaptive screen automatically provides him the menu in his own language (preferences).

After he has a drink and makes a local hotel reservation through the WI-FI connection, he becomes relaxed and activates his availability to meet a person, putting his profile at disposal.  

Chance encounter: An alarm notifies him two answers (of course, from two people in the bar). He accepts one.

Payment: His temporary account indicates the amount to be paid in both currencies with the conversion rate. And he pays by credit card.
