用户界面是系统运行成功至关重要的一部分，考虑如何更有效的为所有用户构建用户友好的人机界面也是很重要的。界面设计应减少人为错误。用户界面设计的目标是让用户的互动尽可能简单而又有效。在我们的系统中,我们尽可能的在每款游戏的界面提供简单易用的用户界面，主要是因为有不同类型的用户和不同年龄段，在对电脑的了解和电脑的操作经验上有不同的层次。主要有4种类型的用户:新手,普通用户,熟练用户和专家。新手用户是那些没有任何计算机系统这方面的知识。普通用户是对语义知识和应用程序有一点了解或对电脑了解一般但对系统的语义知识没有准确的了解。熟练的用户也叫断断续续的用户，他们对应用程序有一个合理的语义知识，但不记得使用界面时必须运用语法信息。专家用户对系统是如何构造的有一个深刻的理解,以及它如何运作。所以在设计任何类型的屏幕或接口之前,我们首先注意下列因素:
The User Interface of a system is critical to the success of a system. It's also important to consider how to build user friendly human computer interface that is more effective for all users. The interface design should reduce human errors. The goal of user interface design is to make the user's interaction as simple and efficient as possible. In our system, we try our best to give simple and easy to use user interface in every game interfaces because there are different kinds of users and groups of age to play game with different kinds of levels in computer knowledge and experience. There are four main types of users: novice, casual, skilled and expert. Novice users are those who have no knowledge any computers systems. Casual users are those who have little semantic knowledge of the application or computer usage in general but not have the exact syntactic knowledge of the system. The skilled users are also call intermittent users. They have a reasonable semantic knowledge of the application but not relatively low recall of syntactic information necessary to use the interface. Expert users have a profound grasp of how the system is constructed and how it operates. So before designing any kinds of screen or interface, we focus on the following factors first:
Who is going to use the screen and system?
Will be using more than one type of user?
Main purpose of the screen.
Level of user intelligence to play game.
Identify audio, vision, effects or animation for K12 game players.
Response time required.
Another consideration for user interface design is that groups of age may also decline in auditory abilities. For audio signals, lower frequency tones in the range of 500-1000 Hz are generally better to hear for increased age.
需求规格—Requirement Specification#p#分页标题#e#
用户需求—User Requirements
Good user requirements are needed for every project, especially computer system projects like game projects, to be successful. For game interfaces, there is some different with others. Following are the some considerations for designing game interfaces in terms of user requirement:
视觉效果—Vision
For Player vision, the developer should avoid using complex color and complicated animation. Then best color contrast is recommended and large font size needs to be required.
听觉效果—Hearing
For Player Hearing, the developer need to be careful to reduce loud background noise, player can be disrupted when playing game. Then less use of high frequency stimuli and the speed of verbal flow has to be adjusted for game players.
注意力—Attention
For Attention, operation commands need to be minimum and stating clear instructions are recommended for all game players.
触觉和动感—Touch and Movement
For Touch and Movement, the developer must avoid movement speed so fast. Next consideration is taking into account the difficulties of using interface, scroll bar, keyboard and mouse and also using single click is better than double click event.
功能要求—Functional Requirements
Functional requirements means to be done by identifying a function of a software system or its component and what a system should be able to do the functions it should perform. Then it has to be done by defining the necessary task, action or activity that must be accomplished. Functional requirement is the plan which is detailed in the system design for implementing functional requirements. For example, games are challenging, they typically include competition (both against a human opponent and a computer generated one). They are often story-based, include compelling characters and they keep scores. Which, if any, of these features are essential to learning still remains to be answered.
非功能要求—Non-functional Requirements
Requirement that specifies criteria that can be used to judge the operation of a system, rather than specific behaviors. Non Functional Requirements is the plan which is detailed in the system architecture for implementing non functional requirements. Game System need to be quick response time, utilization, throughput and static volumetric for performance requirements. The average response time between click and reaction should be less than 0.5 seconds for game interfaces. For usability issues, user interface must be simple and better if without scroll bars because most of the game players don't want to use scroll bar when play game and it's not suitable for game interfaces and interfaces should be appeared with the whole screen. Then, the total number of clicks for any function should not exceed five clicks for maximum because the interface will be more convenient for game players.#p#分页标题#e#
