In order to study users’ spontaneous formulation of commands in the context of multimodal human-computer interaction (HCI), we conducted a Wizard of Oz experiment on the use of unconstrained speechand 2D-gestures for interacting with standard application software: 8 subjects performedvariousdesignand process control tasks during 3 weekly sessions. Some(More)
Within the framework of a prospective ergonomic approach, we simulated two multimodal user interfaces, in order to study the usability of constrained vs spontaneous speech in a multimodal environment. The first experiment, which served as a reference, gave subjects the opportunity to use speech and gestures freely, while subjects in the second experiment(More)
The development of advanced instrumentation for in-pile experiments in Material Testing Reactor constitutes a main goal for the improvement of the nuclear fuel behavior knowledge. In the framework of high burn-up fuel experiments under transient operating conditions, an innovative sensor based on acoustic method was developed by CEA and IES (Southern(More)
This paper describes the activities carried out in order to define the relevant information to be specially adapted so as to enable train drivers to comply with train timetables. We shall describe the chosen methodology used and in particular the combined assessments of some fields of desirable future activity. The interface concept used was designed and(More)
