A Formal Framework for Design and
Validation of Multimodal Interactive Systems
in Transport Domain
4.1. Introduction
The birth of new interaction devices (touch screens, feedback gloves, etc.), the
use of machines in different situations with different users, the use of different modes
(visual, auditory, etc.) has led to a complexity in the use of machines. The integration
of these different media has given rise to a new type of human-computer interface
called the multimodal human-computer interface (multimodal HCI).
The use of multimodal HCI enables the user to intuitively communicate with the
machine; however, the use of several interaction modalities in a sequenced or even
simultaneous manner (speech, gesture, etc.) makes the representation of information
exchanged more arduous and involves a more complex development and validation
process.
The introduction of computerized interactive systems in transport systems,
generally critical, requires them to be highly reliable and imposes safe design
approaches guaranteeing the specifications are respected. These approaches, normally
dedicated to the development of the functional core of systems, are now turning
towards the development of interfaces - an integral part of the system that also plays
a determining role in this type of system; such is the importance of communications.
