What is ISO-FDIS 18075-3:2017

Introduction

ISO-FDIS 18075-3:2017 is a technical standard that focuses on the design and evaluation of text entry systems. This standard provides guidelines for measuring and evaluating the usability of such systems. In this article, we will explore the key aspects covered by ISO-FDIS 18075-3:2017 and delve into its importance in improving user experience.

Scope

ISO-FDIS 18075-3:2017 lays out three areas of focus when it comes to text entry systems: efficiency, effectiveness, and satisfaction. Efficiency refers to the speed at which users can input text, while effectiveness measures the accuracy of the input method. Satisfaction, on the other hand, evaluates how users perceive their overall experience with the system. By considering these three factors, this standard ensures a comprehensive evaluation process.

Evaluation Methods

ISO-FDIS 18075-3:2017 provides detailed guidelines for conducting evaluations of text entry systems. One of the recommended methods is the measurement of text entry speed, which involves calculating words per minute (WPM) or characters per minute (CPM) for different tasks. This allows for objective comparisons between different systems and input methods.

Another important aspect covered by this standard is error analysis. Evaluators are encouraged to record and analyze errors made during the text input process. This includes not only typographical mistakes but also errors when selecting or activating keys. These analyses provide valuable information for improving the system's design and identifying potential issues.

Benefits and Implementation Challenges

ISO-FDIS 18075-3:2017 offers several benefits to both developers and end-users. By adhering to this standard, developers can ensure that their text entry systems are designed with usability in mind. This leads to more efficient and effective systems, resulting in improved user satisfaction.

However, implementing ISO-FDIS 18075-3:2017 may come with its own set of challenges. It requires a thorough understanding of the standard's guidelines and the ability to conduct rigorous evaluations. Additionally, integrating the recommended evaluation methods may require additional resources, both in terms of time and equipment.

Conclusion

ISO-FDIS 18075-3:2017 plays a crucial role in the design and evaluation of text entry systems. By focusing on efficiency, effectiveness, and satisfaction, this standard provides a comprehensive framework for improving user experience. Developers who adhere to these guidelines can ensure that their systems meet the highest standards of usability, ultimately benefiting end-users. While there may be implementation challenges, the long-term advantages gained from applying ISO-FDIS 18075-3:2017 outweigh the initial difficulties.
