Embodiment Construction

[0098] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0099] like figure 1 , a validation method for the usability design of an interactive system, includes the following sequence of steps:

[0100] S1. Modeling: first establish cognitive model, task model and system usability design model, and build an interactive system model with IMPA process algebra; the details are as follows:

[0101] (1) Based on the GOMS cognitive model, decompose the cognitive processing aspects related to the completion of user tasks in the process of human-computer interaction;

[0102](2) Establish a human-computer interaction task model based on the UML use case diagram;

[0103] (3) Establish an interactive system usability design model based on the IMC model;

[0104] (4) Use the formalized language IMPA to establish the formalized specif...

Abstract

The invention discloses an effectiveness verification method for interactive system usability design. The effectiveness verification method for the interactive system usability design includes steps that modeling, to be specific, building a cognitive model, a task model and a system usability design model, and using IMPA process algebra to uniformly build models of an interactive system; stipulating an agreement, to be specific, building a usability agreement of the interactive system, wherein the usability comprises safety and reliability; verifying, using an IMC model verifier to verify the safety and reliability design effectiveness of the interactive system. The effectiveness verification method for the interactive system usability design is capable of forecasting safety disadvantages due to close human error, evaluating the reliability and cognitive complexity of a post-WIMP interface and quantitatively comparing the efficiency of a WIMP interface with the efficiency of the post-WIMP interface.

Description

technical field [0001] The invention relates to a formalization method of human-computer interaction, in particular to a validity verification method for usability design of an interactive system. Background technique [0002] Usability is the effectiveness, efficiency and satisfaction of a specific user using a product to achieve a specific goal in a specific scenario [ISO2011]. An interactive system consists of a user, a computer system, and a human-computer interaction (HCI) process, and its key feature is usability [Dix2006]. The wide application of interactive systems requires more natural, efficient and credible human-computer interaction. Small usability issues can have large economic and social impacts. Fierce market competition requires interactive system designers to continuously improve user interface design to enhance user experience and attract users. Usability has become the focus of competition in the computer industry, and there are strong motivations for ...
