Abstract

Manual control of driver information and support systems carries risks in terms of traffic safety. The manual control of all these systems leads to problems: firstly, manual control cannot be performed 'blind', i.e. without visual distraction from the traffic and secondly, appropriate manual control panels are not available or cannot be installed in a car. An alphanumeric keyboard is difficult to implement in the dashboard and the use of such a device chile driving is obviously risky. Speech recognition systems have progressed to a stage where useful applications exist. This paper investigates the benefit of speech recognition systems in cars. Three different control strategies were compared: manual, speech, and a human assistant. Three systems were examined: route guidance, car telephone and car radio with CD player. The mean number of visual glances per task varied with the experimental conditions. Manual control required the most glances. Only in the condition of speech control were no check glances observed, and it was found that older drivers in particular would gain a great deal from speech control.
