Do slow computer systems impair driving safety?

Although many modern in-vehicle information systems (IVIS) possess delays, up till now, there has been little research about safety-related issues. Therefore the effects of delays in menu interaction on driving performance were investigated. Delay length (0,500,1000 ms), delay type (constant, variable) and the application of an acoustic feedback (with, without) were varied in an artificial menu system. Driver performance was measured with the lane change task (LCT) simulation. Drivers performed significantly better under constant delays. Longer delays did not have an effect on driving performance, though they were perceived as more annoying. To minimize driver distraction, modern IVIS should have constant delays. To improve driver satisfaction, manufacturers of IVIS should avoid long delays in menu interaction.
