Distraction Effects of Manual Number and Text Entry While Driving - Part 1

The Dynamic Following and Detection (DFD) protocol was developed by the National Highway Traffic Safety Administration (NHTSA) to measure the distraction potential of secondary tasks using in-vehicle information systems (IVIS). In recent years, the Alliance of Automobile Manufacturers (the Alliance) developed a set of guidelines for managing driver workload and distraction associated with IVIS. Alliance Principle 2.1 states that the design of systems with visual displays should allow the driver to complete desired tasks with brief sequential glances that do not affect driving. In this study, the authors compare the DFD metrics with the Alliance Principle 2.1 measurement alternatives, and use the DFD distraction protocol to assess the distraction potential of secondary tasks involving manual number and text entry. The findings can assist NHTSA with guidelines for the assessment of distraction potential associated with IVIS in production vehicles or portable devices.
