In-Depth Information
system suggests renting a car rather than taking the bus. Using his smart phone,
Pierre drags and deposits personal information to fill in the car hire form. The
presentation adapts itself to the platform.
Analysis: as the display surfaces of the platforms are heterogeneous, moving
data requires a remodeling of the UI.
Moment No. 3:
Pierre and Christine finally get onto their connecting train. Pierre
consults his smart phone to see their seat numbers. They are in the augmented
compartment; an interactive table is available to users. Pierre goes towards it. The
system suggests moving information to the table. Virtual scissors then appear on
Pierre's smart phone that enable him to cut out the information he wishes to move to
the interactive table. He chooses to display information relating to their journey on
the table. A 3D view of the compartment of the train is displayed. Pierre can
navigate through the compartment by tilting and turning his smart phone. He locates
the seat numbers. Pierre takes advantage of this to visualize a map of the route.
Christine and Pierre can interact at the same time: Pierre consults information
regarding Toulouse station whereas Christine looks at where the seminar is and
locates the hotel they have reserved.
Analysis: it is the proximity of the user to the table that triggers the adaptation.
Moment No. 4:
Once in Toulouse, Pierre and Christine collect the hire car. Pierre
connects his smart phone to the vehicle system. The vehicle system asks him if he
wants his “car preferences” to be transmitted to the hire car. Pierre chooses two
options when he is driving: on the one hand, the display of text messages on the
dashboard and on the other hand, the vocal transmission of road information. Pierre
and Christine take the fast lane. The car system orally transmits the authorized speed
to them. They have been going for about half an hour when Pierre receives a text
message. The message is displayed on the dashboard: it is their colleagues from
Grenoble telling them that they have stopped a bit further on to visit a farm with
local products. Pierre and Christine decide to join them.
Analysis: the display of text messages adapts itself to the available platforms.
11.4. User interface plasticity: system viewpoint
This section is concerned with engineering UI plasticity. It recalls the key
periods illustrated in the field of transport.
