Introduction
Touch screens are widely used in mobile terminal equipment such as mobile phones, tablet computers, and industrial Internet terminals: user is using touch
When viewing a mobile terminal, we often encounter different fluency experience problems: some interfaces have obvious delays in responding to user operations; some pages switch
Not smooth, with a feeling of stuttering or jumping; some applications have slow startup response: These perceptual fluency problems directly affect the user's ability to use
Use experience:
Touchscreen perceived fluidity is not the same as system performance: Although user-perceived fluency is inseparable from the support of system performance, an excellent system
Performance is a necessary condition to ensure smooth user perception, but good system performance does not necessarily lead to good perceived fluency: system performance, resources
Indicators such as speed capability, image rendering technology, and hardware startup speed affect user perception through interface feedback, and determine the optimization of perception fluency:
inferior: For example, the smoothness of application startup and loading needs to pass the time from the user's click action to fully seeing the content of the home page of the interface:
It is measured by the user experience evaluation, including whether the user feels that the home page of the application appears in time, and whether the drawing process of the screen is natural and connected:
These factors will comprehensively affect the user's perceived fluency: Excellent system design can maximize the use of system performance, giving users
Bring the best fluency experience:
This document provides a method for testing the perceived fluency of mobile terminals: Perceptual fluency testing can be used by product manufacturers, service providers, and
Consumers provide important information about the smooth user experience of mobile terminals, providing a basis for product comparison and optimization:
Human-system Interaction Ergonomics of Mobile Terminals
