Driver Workload Guidelines applied to MirrorLink™ Mobile Applications Dr. Matthias Henning HMI Specialist, Carmeq - Volkswagen Group Driver Distraction Task Group, CCC
Overview • Driver Distraction Guidelines • DD Guidelines and MirrorLink™ • MirrorLink™ Developer Requirements
Phone Applications in the Car Phone applications are not designed for use in cars!

DD Guidelines and MirrorLink™Challenges • Different driver distraction guidelines for different regions • Guidelines are designed for a complete system vs. MirrorLink™ ecosystemconsists of different entities • Technical Requirements vs. Driver Distraction Guidelines
Drive-Certified Application RequirementsCompilation of Regional Guidelines – EU ApplyESoP
Drive-Certified Application RequirementsCompilation of Regional Guidelines – EU & NA Combine AAM andESoP
Drive-Certified Application RequirementsCompilation of Regional Guidelines – Global Global Guidelines
Divided/Shared Responsibility Example AAM Guidelines • Installation Principles • Head unit installation • Information Presentation Principles • e.g., workload, font size, contrast • Principles on Interactions with Displays/Controls • e.g., chunkibility, pace of interaction • System Behavior Principles • e.g., no video, lock of functions • Principles on Information About the System • documentation Head Unit Smartphone Application
MirrorLink™ Developer Requirements“Cookbook” for Developers to pass Drive-Cert Testing • Restricted Content • Excerpt: “Video-based entertainment SHALL NOT be used. Notable examples are streaming applications, …” • User Interface Accessibility and Responsiveness • Excerpt: “The foreground and background of an application SHALL have a Brightness Difference equal to or greater than NN.” • Driver Workload • Excerpt:“One of the following criteria will be used to verify that an application does not exceed critical driver workload thresholds: • Occlusion Method …” • Golden Rules for minimizing driver workload • Excerpt: “Limit visual and auditory list length”
MirrorLink™ Developer RequirementsMinimizing Driver Distraction • Guiding Principals • Nothing that demands the driver’s attention • Quickly comprehendible and accessible • Restricted Content • No video, incidental animations or flashing • No automatic scrolling text • Visual Accessibility • Color contrast – brightness & color differences • Text legibility (Minimum height, Font requirements) • Manual Accessibility • No two-handed operations • Control sizing and spacing
MirrorLink™ Developer RequirementsMeasuring Driver Distraction • Only NAand Japan • Occlusion Testing • Bench testing with a pool (~24) of users • 50% male, 50% female • 45-65 years of age • 1 hour training • Special goggles that switch from transparent (1.5 seconds) to opaque (1 second) • Must be able to perform a task with a total open time of less than 15 secondsfor 85% of testers
MirrorLink™ Developer RequirementsMeasuring Driver Distraction • Only NA • Additional Test Methods Pending • Eye tracking simulation testing • Driver performance simulation testing • Only 1 method will be required – app developers will be able to choose their preferred method
Conclusion – DD Guidelines and MirrorLink™ • The MirrorLink™ Developer Requirements: • cover the most relevant criteria for the driver workload • use a common format for all regions • give additional hints for a good HMI • are ready to be published • The developer requirements support developing of applications that can be used while driving
