@article{ref1, title="Integrative assistance: a 'task-timer' to counteract possible driver distraction effects", journal="VDI Berichte", year="2006", author="Totzke, I and Schoch, S and Kruger, Hans-Peter", volume="2006", number="1960", pages="403-419", abstract="Driver information systems may lead to detrimental effects in driving which may be counteracted by ADAS. However, existing ADAS (e.g. ACC, HC) only lead to a non-specific compensation of possible effects of secondary tasks while driving. Therefore, an alternative is introduced which informs the driver that he has been handling the information system too long (here: 2s) and that he should guide his concentration on driving. By this so-called "task-timer" an optimal time-sharing ability shall be trained. In contrast to this, a combined "lane-position-headway-warning" is introduced which informs the driver about critical lane positions and headways (close following) while handling the information system. An empirical study with N = 24 subjects (driving simulation with movement system) was conducted. Half of the subjects drove with the "task-timer" or "lane-position-headway- warning", respectively. As menu structure was identified as one difficulty relevant aspect of information systems half of the subjects of each group had to handle a broad or a deep menu system while driving. The introduction of the "task-timer" leads to a deterioration of menu handling and to higher driver workload. However, detrimental effects of menu handling on driving are not as aggravating. In general, the subjects accept the concept of a "task-timer". Therefore, further empirical studies are required which particularly deal with an optimal ergonomic design of the so-called task-timer.
