摘要: This report supplements the proposed NHTSA Driver Distraction Guidelines for Visual-Manual Interfaces with explanatory information and examples about the definition of a task. It is intended to assist those using these Guidelines. The contents of this report are the opinions of contractor personnel; they are not necessarily official NHTSA policy. This report is believed to be consistent with NHTSA's proposal of February 24, 2012. The material provided herein is offered to facilitate a common and shared understanding of the definitions needed for consistent and rigorous testing of tasks that may be performed using electronic devices that are within the scope of the NHTSA Driver Distraction Guidelines. This report particularly focuses on the definition of a testable task, and on supporting definitions which are used in conjunction with it (for example, definitions such as start of measurement and end of measurement). These definitions are needed when device tasks are tested to determine whether the proposed acceptance criteria of the NHTSA Distraction Guidelines have been successfully met. This report provides numerous examples which illustrate how to apply the definitions for testing purposes, and discusses some of the challenges that exist in applying definitions to tasks in real system architectures.
