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 speech and 2D-gestures for interacting with standard application software: 8 subjects performed various designand 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 report is the final report of the first phase of a study of head up displays (HUD) symbology conducted for DGAC/SFACT, in the frame of its pre normative research program for civil aviation safety. This report describes the main steps and results of the study : 1. Comparative analysis of the JAA and FAA regulations concerning HUD in general, and more(More)
Three experiments were conducted on 90 flying personnel to determine the role of luminance, hue, and saturation contrasts on angular visual acuity measured on a CRT system. A Snellen E test object was displayed under various visual acuity conditions on a TV screen, in color contrast, using red, yellow, green, cyan, blue, purple, white, and black. The(More)
