While haptic and auditory feedback on in-car touchscreens do not enhance driving or task performance, users express a preference for multimodal feedback over visual-only interfaces. This human factors research insight is drawn from a 2012 study published in Academic Publication. Using Experimental with 48 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize user preference for multimodal feedback in automotive touchscreens, but carefully manage feedback implementation to avoid unintended increases in cognitive load or interference.

Application

Design takeaway

Prioritize user preference for multimodal feedback in automotive touchscreens, but carefully manage feedback implementation to avoid unintended increases in cognitive load or interference.

How to apply

When designing in-car interfaces, consider offering users options for haptic and auditory feedback alongside visual cues, and conduct user testing to gauge preference and identify potential workload issues.

Project actions

  • 01When testing interfaces, consider not just performance metrics but also subjective user preference.
  • 02Explore how different combinations of sensory feedback might influence user experience in your design project.

Method & Evidence

AimTo evaluate the effect of different combinations of visual, audible, and haptic feedback on in-car touchscreens on driving performance, task performance, affective response, and subjective workload.
MethodExperimental
ProcedureParticipants completed a dual-task scenario involving a Lane Change Test (driving task) and realistic automotive touchscreen tasks. Different combinations of visual, audible, and haptic feedback were presented for the touchscreen interactions.
Sample48 participants
ContextAutomotive infotainment systems, human-computer interaction in vehicles.

Variables

IVType of feedback (visual only, visual + audible, visual + haptic, visual + audible + haptic).
DVDriving performance (e.g., lane deviation), touchscreen task performance (e.g., completion time, accuracy), affective response, subjective workload.
CVParticipant expertise (non-expert), driving task (Lane Change Test), touchscreen tasks (realistic automotive use cases).

Strengths & Limitations

Strengths

  • +Employed a realistic dual-task methodology to simulate in-car usage.
  • +Investigated multiple outcome measures including performance, affect, and workload.

Limitations

The complexity of implementing and controlling different feedback modalities can be a practical challenge. Generalizing findings to all user groups or driving conditions may be difficult.

Reliability & validity

The study's validity is supported by its use of a dual-task methodology mimicking real-world conditions. Reliability could be enhanced by standardizing feedback intensity and duration across all participants.

Think critically

Given that multimodal feedback did not improve performance, what are the ethical implications of implementing it in safety-critical systems if it potentially increases cognitive load or distraction, even if users prefer it?

05

Design Principles

"User preference for richer sensory feedback in interactive systems can be a design goal, but must be balanced with performance and cognitive load considerations."

This insight highlights a critical consideration for automotive interface design. Designers must balance the desire for enhanced user experience and perceived sophistication with the reality that adding feedback modalities may not yield measurable performance gains, and could potentially introduce complexities in cross-modal interaction or workload.

06

What This Means for Your Design

Making car touchscreens vibrate or make sounds doesn't make you drive or use the screen better, but people tend to like it more when there are more ways to interact (seeing, hearing, feeling).

How to use in your project

  • 1.Reference this study when discussing the trade-offs between user preference and objective performance in your design project's evaluation phase.
  • 2.Use the findings to justify design choices related to feedback mechanisms in your chosen interface.

Paragraph starter

Research by Pitts et al. (2012) indicates that while multimodal feedback (including haptic and auditory cues) on in-car touchscreens does not improve objective driving or task performance, users express a preference for these richer interfaces over visual-only options. This suggests that user satisfaction can be enhanced through sensory feedback, though careful design is required to mitigate potential increases in workload or cross-modal interference.
