Overview - What ISO 8202:2025 covers

ISO 8202:2025 defines a standardized, laboratory-based dual-task method - the Box Task + Detection Response Task (BT + DRT) - to quantify how secondary in‑vehicle tasks degrade performance on a driving‑like primary task. The standard provides definitions, performance metrics, equipment and procedural minimums, and instructions for data capture, analysis and reporting to assess visual‑manual and cognitive secondary‑task demand associated with visual‑manual or auditory‑verbal interactions with IVIS (in‑vehicle information systems).

Key topics and technical requirements

• BT + DRT method: Combines a two‑dimensional continuous tracking Box Task (dynamic box controls lateral position and headway) with a Detection Response Task (DRT) to assess attention and cognitive load.
• Performance metrics:
  • Box task metrics: box position variability, box size variability, lateral and longitudinal error states.
  • DRT metrics: response time and hit rate.
• Measurement setup:
  • Minimum equipment guidance for display of driving scene, steering wheel and gas pedal controls, and DRT stimulus/response hardware (including tactile DRT options).
  • Requirements for data capture, sensor use, and documentation of setup.
• Procedure and study design:
  • Participant selection, instructions, training, baseline runs, dual‑task conditions, and trial definitions.
  • Methods for calculating, analysing and interpreting differences between dual‑task conditions.
• Scope limits: Designed for standardized laboratory experiments and comparisons across secondary tasks; does not apply to measurement of primary driving‑task demand.

Practical applications

• Evaluate the visual‑manual and cognitive demand of IVIS features, smartphone apps, and voice/gesture interfaces during driving‑like tasks.
• Support early‑stage human‑factors testing in driving simulators, surrogate driving setups, or controlled labs to identify distracting interactions.
• Enable objective, comparable metrics for product design iterations, usability testing, and pre‑regulatory assessments of driver distraction.

Who should use ISO 8202:2025

• Automotive OEMs and after‑market IVIS developers
• Human factors / ergonomics researchers and test laboratories
• Safety engineers, HMI designers, and regulatory bodies assessing driver distraction
• Developers of driving simulators and usability test protocols

ISO 8202:2025 provides a practical, standardized approach to quantify and compare how secondary tasks affect driver attention and manual control, helping stakeholders reduce distraction risk and improve IVIS design.
