A usability evaluation toolkit for In-Vehicle Information Systems (IVISs).

Area of Science:

• Human-Computer Interaction
• Automotive Engineering
• Usability Engineering

Background:

• Usability is critical for In-Vehicle Information Systems (IVISs) to ensure driver safety and enhance the driving experience.
• Current methods for evaluating IVIS usability often lack context-specificity, leading to suboptimal design outcomes.
• A structured approach is needed to guide the definition and evaluation of IVIS usability.

Purpose of the Study:

• To present a framework for evaluating the usability of In-Vehicle Information Systems (IVISs).
• To guide designers in defining context-specific usability criteria and selecting appropriate evaluation methods.
• To facilitate an iterative design-evaluation-redesign process for improving IVIS usability and driver experience.

Main Methods:

• The framework emphasizes defining usability based on the specific context of use for the IVIS.
• It outlines four guiding principles for selecting evaluation methods: information needs, evaluation stage, resources, and personnel.
• The framework supports an iterative process of design, evaluation, and redesign.

Main Results:

• The proposed framework provides a systematic approach to usability evaluation for IVISs.
• It enables designers to tailor usability criteria and methods to the specific in-vehicle context.
• The iterative process aims to enhance IVIS usability and the overall driving experience.

Conclusions:

• A context-driven framework is essential for effective usability evaluation of In-Vehicle Information Systems (IVISs).
• Implementing this framework can lead to improved IVIS usability, a better driving experience, and maintained driver safety.
• The iterative design-evaluation-redesign cycle is key to optimizing IVIS functionality.
