Chapter 13

Evaluation is introduced in this chapter. It is quite an important in the process. It is integral to the design process. Evaluators collect information about users’ or potential users’ experiences when interacting with a prototype, an app, a computer system, a component of a computer system, an application, or a design artifact such as a screen sketch. Evaluations usually involve observing participants and measuring their performance – in usability testing, experiments, or field studies. In the evaluation part, we usually will creat a prototype to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. Prototyping is an essential part of designing as it allows users or testers to evaluate design of a product interactively and also test its feasibility.

Chapter 15

Two methods of inspection which are heuristic evaluation and walkthroughsare are introduced in this chapter.

In theoritical, a heuristic evaluation is a usability inspection method for computer software that helps to identify usability problems in the user interface (UI) design. It specifically involves evaluators examining the interface and judging its compliance. It is guided by a list of usability principles, such as visibility of system status, match between system and the real world etc. Usually, in the inspectation part the expert is the one that will be engaged istead of the user.

Cognitive walkthrough is task-specific, whereas heuristic evaluation takes a holistic view to catch problems not caught by this and other usability inspection methods.The designer will woek together with some experts in this process. The Pluralistic Walkthrough is a usability inspection method used to identify usability issues in a piece of software or website in an effort to create a maximally usable human-computer interface. In this method it will engage the users, the experts and the

Questions:

1. In our project, if we want to create an interface for the visitors of the ferry, do we need to create a prototype first?
2. How can we collect the data of how the people feel when they are interacting with the product when prototyping?
