How to evaluate and analyze user experience

As the name implies, user experience is a purely subjective psychological feeling, there are many uncertainties and individual differences, it is not easy to accurately assess the user experience

The reason is not easy, because:

1. Lack of standards for user experience

1) The definition of user experience, now always floating in the theoretical level, the lack of a clear assessment criteria.
2) Different products have different emphases on the components of user experience.

2. Lack of effective assessment methods

1) There are uncertainties in the experiment, and there are individual differences in users.
2) Evaluation of large sample size Higher testing costs.

Therefore, in order to be able to accurately assess the user experience, the evaluation criteria should focus on the practicality and operability, following the following principles:

1) All evaluation criteria are quantifiable and provide detailed assessment data.
2) Evaluation criteria can be measured and observed in real terms, and reproducible.
3) Evaluation criteria can be reviewed on a periodic basis to verify improvement over a specified period of time.
4) Evaluation criteria should have good structural validity.

At present, the research on evaluation criteria can be divided into two categories: content evaluation criteria and user focus evaluation criteria.

Concerned about the content of the index system

Such as http://www.aliyun.com/zixun/aggregation/9394.html"> Nielsen proposes four new usability parameters: navigation, response time, Credibility and content. In addition, Agarwal and Venkatesh The Microsoft Usability Guidelines (MUG) is proposed to evaluate website usability. The index includes five dimensions: ease of use, Made for the Medium, emotion, content and promotion. .

Affected by this, many researchers put forward similar views, such as Turner will usability into navigation, web design, content, accessibility, multimedia use, interactivity and consistency. Some scholars also through a variety of empirical studies to further analyze the importance of various website usability indicators. For example, Monideepa Tarafdar et al. Analyzed the impact of the existing website usability design indicators on the website, and found that website design factors such as information content, navigation system ease of use, download speed, website accessibility and availability are positively related, Website security and customization are not related to usability.

Concerned about the user's index system

As far as research ideas are concerned, this part of the researchers investigated the construction of website usability assessment index system more from the perspective of user behavior analysis. Some scholars discussed this issue theoretically. For example, Venkatesh et al. Introduced the Technology Acceptance Model (TAM) into the field of usability studies. He believes that the importance of tasks and the user-friendliness of the system determine the degree of user acceptance of the technology. In addition, metrics such as ease-of-use, user-friendliness, and customer satisfaction have also been shown to have a decisive effect on site availability.

It should be pointed out that the division of usability indicators into two categories of so-called focus content and user focus does not mean that the former does not focus on the user but the latter does not focus on the content, but rather on the departure of the two types of research ideas Words. Judging from the composition of specific indicators, the difference between the two types of research is not actually obvious. In practical work, it is still necessary to summarize the evaluation index system according to the characteristics of the specific product evaluated, and to achieve the purpose of evaluating the whole system by evaluating each index contained in the index system.
