A Recent Case Study:

Recently, our team conducted an eye tracking study to evaluate the usability of different IFU variations for a novel medical device. The study aimed to analyze user gaze patterns, identify areas of difficulty, and ultimately optimize IFU design for safe and efficient use.

Key Findings & Visualizations:

• Visual Attention and Ease of Use: Eye tracking data revealed that one IFU variation elicited the most even gaze distribution across all sections, suggesting a more efficient layout of information. This, coupled with shorter overall fixation durations, strongly suggested that this IFU variation provided the greatest ease of use for users.

• The Impact of Imagery: Another IFU variation, while engaging with its realistic imagery, exhibited longer text fixation durations, indicating that the detailed imagery, while visually appealing, potentially slowed down user comprehension.

• The Role of Text and Visual Cues: The study highlighted the importance of concise text and effective visual cues. The IFU with the most concise text and clear visual guidance facilitated smoother user interaction and improved comprehension.

  • Visuals of some heatmaps, gaze sequence path, AOI fixation data to illustrate

Recommendations for Your IFU Design:

Based on these findings, we recommend an IFU design that incorporates the following:

• Efficient Imagery: Leverage large-format images and visually meaningful graphics to enhance user engagement and understanding while ensuring they do not overwhelm or distract the user.

• Effective Use of Visual Cues: Utilize visual cues such as symbols, icons, and colour coding to guide user attention and improve the clarity of instructions.

Eye tracking technology provides valuable objective insights into how users interact with medical device IFUs, enhancing overall usability and effectiveness. By analyzing user gaze patterns, we can identify areas of difficulty and incorporate these findings into the design process. This approach ensures the creation of more user-friendly IFUs, ultimately improving patient safety and increasing overall product satisfaction.
