Research on the Usability of information Positioning Interaction Method in Instant Messaging App

Abstract

Objective: This paper investigates an interaction method for quickly finding a target message in an instant messaging app and uses usability testing to determine whether this interaction method improves usability.<BR><BR>Background: With the development of Internet technology and the widespread use of social media, instant messaging apps have become a must-have app for everyone. Due to this convenience, users need to deal with a large amount of information every day and searching and filtering consume a lot of time. It is necessary to study new interaction methods to solve problems.<BR><BR>Method: Analyzed the structure of the focus area of the instant messaging app message lookup, identified problematic points and designed a new interaction method and prototype. Conducted usability evaluation of the old and new interaction methods using objective methods. 1) Designed experiments and questionnaires around three aspects of usability, effectiveness, efficiency, and user satisfaction. 2) Recruited testers to conduct tests. 3) Performed statistical analysis of the obtained data.<BR><BR>Results: The efficiency and user experience of the new interaction method can be greatly improved, and the learning cost is low. The new interaction method significantly reduces the disadvantage of increasing the number of messages affecting the finding time. No matter how many messages it takes only about 6 seconds.<BR><BR>Conclusion: With the increase of users
