Analysis of Suzuki infotainment system for elderly.

PROBLEM
FM radio controls in modern infotainment systems create invisible friction for older drivers, especially when the system gives no feedback during critical actions.

POV OF
Jaiveer is 55 and is familiar with FM radio and used to button-based interfaces, which are similar to the touchscreen layout. He has good memory and doesn’t get confused easily but struggles when unexpected errors occur or when the system resets. He mostly uses FM radio and isn’t familiar with other car features.

WHY USE DIS-CO METHOD
Most usability methods told me what went wrong. But DISCO also told me why it felt wrong, by mapping cognitive load, display friction, stress, error risk, and ease of use at every single step of the interaction.

Strenghts
Deficiencies

Strenghts
Deficiencies

Minimal spacing between element groups reduces glancability
FM is inside a widget stack, small swipes leads to unwanted swipes
Missing pause button for FM and media options in widget.
Low visibility for text and icon elements due to crowded background
Font size hierarchy not established for active widget elements

Constraints.
I did considered redesigning the entire infotainment but scoped down to the FM flow because of the project timeline of 2 weeks, which helped me to focus on depth over breadth for the project.
