Résumé / Abstract
This report has been drawn up in the framework of collaboration between the PROMISE (Personal mobile Traveller and Traffic Information) and TELSCAN (TELematic Standards and Coordination of ATT system in relatioN to elderly and disabled travellers) projects. This experiment focused on the evaluation of different control interfaces of an in-vehicle Internet navigator for carrying out different types of task on a driving simulator. This experiment on the Renault driving simulator did not concern the use of the PROMISE France Internet site, which can be accessed via a PC, but a fictional site that makes use of certain of the services of this web sit (District Map, Route), as well as other services such as electronic messaging, cinema programmes and phone directory identified as useful for the PROMISE concept. The <<PROMISE>> Internet site is presented in the form of an in-vehicle screen built into the vehicle dashboard and controlled by three control devices: - a keyboard located above the gear stick, - a tactile pad located near the steering wheel, - a vocal command. The experiment was divided into two parts: - A quantitative evaluation: carrying out a certain number of actions on the system by using only one control device, i.e. the tactile pad or the keyboard. For each action, a comparison of the control devices can be carried out for task duration time, errors, lateral deviation, time between vehicles, speed. - A qualitative evaluation: in this stage the subjects had the possibility to use a new control device: a vocal command. Instead of executing the actions demanded (as in the first experiment), the subject had to follow a scenario which began by reading an electronic message. On the basis of the content of this message, the subject deduced the different tasks to be carried out. To accomplish these tasks (confirm, cancel, enter a name, etc.), the subject could use as wished one of the three control devices: speech, the keyboard or the tactile pad. Thus, the subject used the device they felt was most appropriate for each task. ; RAPPORT DE CONTRAT
