Design Considering Driving Safety

Apps running on Pleos Connect must be designed with the vehicle environment and driving conditions in mind so that they do not distract the driver. Whether an app can be used while driving and which functions are restricted may vary depending on the driving state, region, and app category. Follow the AAOS Driver Distraction Guidelines and pay attention to the following UX principles in design and development.

App Behavior Under Driving Restrictions​

Whether an app can be used while driving and which functions are restricted may vary depending on the driving situation, region, and app category. For details, see the following documents.

Apps must use CarUxRestrictions to check the restriction state while driving and appropriately reduce or disable the UI and behavior of restricted functions. Prevent video playback from starting or resuming while driving restrictions apply. For audio playback, follow the policy defined in the Audio Focus Development Guide.

UX Design Principles to Reduce Driver Distraction​

Minimize Visual Distraction​

  • Display information needed for driving clearly and concisely so that the driver can understand it quickly. When using HUD, cluster, or OSD areas provided by the platform, follow the policies for those areas.
  • Minimize or restrict videos, animations, and moving images that excessively attract the driver's attention while driving.
  • Use images only as needed to convey information, and avoid decorative or repeatedly moving visual elements.

Information Architecture·Interaction​

  • Prioritize information and functions needed while driving, and place them where the driver can understand and use them quickly.
  • Simplify screen and menu structure so users can reach necessary functions with minimal interaction.
  • Place frequently used functions on the first screen or top area, and avoid overusing dropdowns and multi-level menus.
  • Minimize automatic animations and repeated screen transitions that excessively attract the driver's attention while driving.
  • When important driving-related audio guidance is playing, respond appropriately according to the audio focus policy, such as pausing media playback or adjusting its volume.

Touch Interaction Optimization​

  • Apply large touch targets, high contrast, and minimal text patterns in accordance with the Pleos Connect UI Design Guide.
  • Minimize touchscreen interactions and support interaction through voice commands or vehicle-provided input methods such as physical buttons.
  • Do not induce activities that may distract the driver, such as games, web surfing, or fitness.
  • Follow the Pleos Connect UI Design Guide for button sizes and spacing between touch targets.

Minimize Text Input · Prioritize Voice · Presets​

  • Even for search and login, prioritize preset selection, recent items, and voice input over keyboard input.
  • Place frequently used functions such as preset playlists, recently played items, and favorites on the first screen of music apps.
