What is BS EN ISO 9241-307:2017?

Introduction

BS EN ISO 9241-307:2017 is an international standard that provides guidelines for the design and evaluation of tactile feedback for interactive systems. The standard, published by the International Organization for Standardization (ISO), aims to enhance the user experience by incorporating haptic or tactile sensations into user interfaces. This article will delve into the technical details of the standard and explore its significance in the field of human-computer interaction.

Tactile Feedback Design Principles

In accordance with BS EN ISO 9241-307:2017, the design of tactile feedback should adhere to several key principles. Firstly, it should be perceivable and appropriate to the task, meaning that users should be able to recognize and understand the feedback provided by the system. Secondly, it should be compatible with the user's capabilities, considering factors such as age, disability, and previous experience. Thirdly, tactile feedback should be consistent and predictable, allowing users to develop a mental model of how the system responds to their actions.

Furthermore, the standard emphasizes the importance of providing feedback that is timely and informative. Tactile signals should be presented in a timely manner, enabling users to quickly react to them. At the same time, the feedback should provide meaningful information about the system status or the consequences of user actions. Additionally, the design should take into account user preferences by providing options for customization, allowing individuals to tailor the tactile feedback according to their own needs and preferences.

Evaluation Methods for Tactile Feedback

BS EN ISO 9241-307:2017 also outlines various methods for evaluating the effectiveness of tactile feedback in interactive systems. One commonly used method is user testing, where participants interact with the system while their reactions and feedback are recorded. This allows designers to assess the user's perception of the tactile feedback and make adjustments accordingly.

In addition to user testing, objective measurements can be conducted to evaluate the physical properties of the tactile feedback. These measurements may include factors such as force, pressure, vibration frequency, and amplitude. By quantifying the physical characteristics of the feedback, designers can ensure that it falls within the specified parameters outlined in the standard.

Benefits and Implications

The incorporation of tactile feedback in interactive systems has the potential to greatly enhance the overall user experience. By providing users with haptic sensations, such as vibrations or textures, the system can convey information more effectively and intuitively. This is particularly beneficial for individuals with visual impairments or those operating in situations where visual attention is limited.

Furthermore, adherence to BS EN ISO 9241-307:2017 ensures that tactile feedback is designed and implemented consistently across different systems and devices. This promotes a more seamless and standardized user experience, allowing individuals to easily adapt to new interfaces without having to learn entirely new interaction techniques each time.

In summary, BS EN ISO 9241-307:2017 plays a vital role in guiding the design and evaluation of tactile feedback for interactive systems. By following the principles and guidelines outlined in the standard, designers can create user interfaces that are both intuitive and efficient, ultimately enhancing the usability and accessibility of technology for individuals around the world.
