烟台南山Introduction
All too often when designing complex systems, developers concentrate their effort on expanding system features or maximizing system performance—neglecting, if only temporarily, the important issue of making the systems usable to people. This tendency is both quite natural and misguided. It is natural becau the construction of a rich and fast application pos challenges and uncertainties that em to require our undivided attention. However, it is misguided becau a system with a poorly designed ur interface will be ud inefficiently and, probably, ldom—no matter what a system's technical merits are.

Though it is increasingly common for developers of new systems to focus specifically on the design of ur interfaces, it is still often the ca that this important aspect of design is not given the attention it is due. The result is that many new programs overtax peoples' capacities for perceiving, recalling, and acting, and that, therefore, the programs interact with urs very ineffectively. Not only is this true for programs and computer systems, but also for many other things—from appliances, to cars, to buildings. Most of us have heard the jokes about "programmable" VCRs, puzzled over simple tasks like heating water in a new microwave oven, or fumbled at the steering wheel while looking for a "scan" button on a car radio. However, how often do we stop to consider 板载声卡why the things are difficult to u and what would make their interfaces more usable?
The Assignment
The goal of this exerci is to focus your critical thought on tho features of a computer system that promote usability or hinder it. To this end, you will be asked to write a short essay discussing the usability shortcomings of an application of your choosing. Note that
many technically elegant and successful applications are suitable candidates for scrutiny—since, sadly, technical virtue and usability are often not found together.
As you examine the application, think about usability issues in order to find specific reasons why the application's interface fails in some respect, and then propo solutions to correct this failing. As much as you are able, ground your reasons for both the failings and the solutions on the principles of psychology you have just been introduced to. Also, propo a way to test your solution—to e if it really address the problem, not merely your individual taste. That is, you will need to propo an experiment that will demonstrate the effectiveness of your solution for real urs.
Plea note that, to a considerable extent, the tools you need to carry out the tasks successfully are covered in detail in ctions of this cour that you have yet to take. However, this is not a problem: the purpo of this initial exploration of usability issues is to 1) give you an opportunity to reflect on the importance of good human-centered design, 2) allow you to practice thinking about the psychology of the urs in a focud way, and 3) allow you to apply this psychology reasoning to ur interface design.
What you must do:
白杨礼赞朗读1. 有创意的广告文案Choo an application to obrve. This can be a Web page, a standard application, a utility program—even a gadget or appliance that has interesting ur-interface features.
2. Write an essay of no more than two pages in length. The essay should include:
o A brief description of the system or application you are critiquing. If at all possible, include a picture or drawing to help us understand this application. 进位乘法
o A conci statement of the problem you have obrved.
o An explanation of why you believe this is a problem bad on the content of "1.1.3 Basic Psychology Needed for Interface Design." (Don't merely say that a feature is "annoying" or "ugly," but explain how it forces a ur to perform the tasks of perceiving, processing, or acting in ways that are difficult for people.)
o A suggestion for improving the design and a rationale for that suggestion.
(When proposing a solution, try to be as realistic as possible and not suggest costly or complicated enhancements. For example, it probably would not be reasonable to propo that VCRs should recognize and process human speech, as this would make them very expensive, if not unfeasible to build.)
