Embodiment Construction

[0042] In order to make the objectives, technical methods and advantages of the present invention clearer and easier to understand, the present invention will be further described in detail below in conjunction with specific embodiments and diagrams. However, it should be noted that this specific embodiment does not limit the application scope of the present invention.

[0043] During the implementation process, a usability evaluation method for medical device instructions based on visual behavior, its main implementation steps are as follows:

[0044] A Tobii TX 300 eye tracker was used to test the eye movement data of the subjects when they read the instructions for use of two medical devices (Raphael, Weikang ventilator instructions). And the description is divided into different areas of interest (AOI) for comparative testing.

[0045] Among all the measured data types, five eye movement data types related to the usability evaluation were selected as indicators for the su...

Abstract

The invention provides a method for evaluating the usability of eye movement technology based medical device manual, which utilizes a Tobii eye tracker to obtain the eye movement data of a subject who reads two kinds of medical device manuals. Five kinds of eye movement data associated with the usability evaluation are selected for analyzing cognitive activities and as usability indexes. According to the relationship between the five kinds of eye movement data and cognitive activities and based on three criteria of attraction, search speed and search accuracy, the using effect of the manual is evaluated. The questionnaire is used to evaluate the rationality of an eye movement model. The variance of five kinds of eye movement data under different areas of interest are analyzed by single factor analysis of variance. A multiple comparison method is used and comprehensive analysis is done in combination of the evaluation results of the eye movement model so as to find the influence of different types of interest areas on the eye movement data and put forward suggestions on usability improvement. The method, with high accuracy and quantitative characteristics, has strong reference value for the design and improvement of such manuals.

Description

technical field [0001] The present invention relates to the field of human factors engineering, and more specifically, relates to an eye movement technology-based method for evaluating the usability of medical device instruction manuals. Background technique [0002] Written instructions with clear concepts play an important role in teaching people how to use medical devices safely and effectively. Usability testing can help identify strengths in instructions and provide suggestions for improvement. Often, however, information that the designer considers to be highly readable may not appear to be so to the intended user. Instructions for use of medical devices should be as easy to read as possible, such as setting bold fonts, etc., and facilitate users to effectively extract information from them, such as setting tables and pictures. Different designs can have a great impact on the effectiveness of the instructions. Therefore, for the instructions for use of medical devic...
