英语作文《关于手机的使用》

Hello,every one ,the title of my speech is:

On The Use Of Mobilephones

然后开始下面的正文:

Nowadays,mobilephones are becoming more and more widely used by people,especially among our young。Almost every one of us has a mobilephone,some people even get more than one.Wherever we go,you can find people using phones.Even,to some people, mobilephone is almost their lives,they can’t live without it.

There are many reasons accouting for this phenomenon.first of all,some people say that they can use their phones to keep in touch with their friends who are far away from them,and they can call for help if they are in trouble.In addition,as there are more and more functions in cell phone ,people can use it to search the internet,play games,chat with others,even buy some things.

However,every thing has two sides.we must find the fact that Mobile phone radiation is harmful to the body.It’s also detrimental to our eyes to look at the Phone screen for too long.besides,it’s a weste of time and

money to use phones too often.

Considering the above situation,I think we should limit the use of cell phone in addition to phone calls and check information ,then we can save a lot of time and money to do some Beneficial things,and only then we can live a happy and health life.

演讲完毕的结尾句:

That’s all,thank you for you listening.

探索老年人的手机界面设计

摘要:这项研究评估了手机操作性能上的界面设计对老年使用者的影响。为了实现这一目标,目前研究采用课一个2 × 2的学科实验设计,在软件接口和硬件接口的基础上制定不同的实验处理。一共有20名受试者,包括10个年纪较小(15-30岁)和10年龄较大(40岁以上的)的参与者在这个实验中进行测试。在研究中有三个因变量。第一个措施是在实验中执行多个任务的对象所运行的时间。第二项措施是指错误的频率,指对象在运行时出现错误的步骤。第三个是主管变量,通过一个7点李克特量表衡量。最后,最后,本研究讨论中年人士的手机设计的设计方向。这个结论为手机设计的研究提供了有益的参考。

关键字:老年人,手机,界面设计【手机应用英语作文】

1介绍

手机是在技术领域增长最快的产品之一。在台湾,超过69.9%的人有手机[18]。此外,随着信息技术的进步,手机将成为日用品之一。目前的手机设计的趋势是制造更小,更轻的,比过去有更多的功能。因此,加强对手机界面的复杂性是至关重要的是用户操作。据黄[9]所研究的,方向键是手机的硬件接口,可以分为两种类型,如交叉和电子。此外,主菜单在屏幕上,手机软件接口也可以分为两种类型,如矩阵和页面。主菜单页面类型是只在屏幕上显示符号和文字的单一选项。用户需要使用方向键操作屏幕上的其他选项页。另一方面,矩阵式的主菜单一旦安排一样在屏幕上的矩阵就会显示九个或十二个符号和文字的选项。

界面设计无疑是成功经营的手机为用户最重要的因素之一。不过,如果界面设计人员没有考虑用户的认知方面,当他们设计了一个手机界面,用户将更有可能在使用手机的时候遇到困难[19]。用户不会快速了解所有功能,也会对简单的矩阵式界面所混淆[29]。一些用户体验的研究已经表明,目前的设计趋势可能对老年人带来不便

[1][14][27][2]。因此,如何找到最合适的方式来显示功能,是手机的设计者的意义所在。

在台湾,45岁以上的人口从1980年的350万增加到2007年的800万。根据上述,老人在台湾的人口比例和增加台湾的人口结构将进入老龄化社会。老龄化是指一个对人类[6]生理年龄的增加的影响的过程。老龄化广泛影响人类行为。人体机能在40岁开始下降,显著影响生理能力[17]。许多研究表明,随着他们的年龄增加,老人的智力,记忆力,注意力将退化越来越多,[12][8][4][24][11][7][25] [28],这使老年人难以学习新的技能[22][30]。然而,一些研究表明,大多数手机往往度身订造的年轻人想要什么,但似乎忽视老人的要求,留给老人[3],只有少数种类和选择;[3][20][16][23][15]。因此,老人在使用为年轻人设计的手机时感到沮丧。本研究的重点是探究适合老年人的手机硬件和软件设计。

2方法

在学科实验设计本研究采用2 × 2,制定不同的根据不同类型的软件接口(矩阵和试验性治疗页)和硬件接口(交叉和电子对)。一个用于蜂窝电话的用户界面设计,包含四个用户界面,不同的软件界面和硬件接口。这项研究评估了手机界面的影响设计上的中年人士的经营业绩。

在研究中的三个独立的变量。其一是指用户的年龄,比较年轻(15-30岁)和老年人(40岁以上)的经营业绩。第二个变量是手机的软件接口,由不同的手机屏幕定义的主菜单的类型。第三个变量是手机的硬件接口,方向键盘控制软件见面选项。

作为因变量,对不同的手机界面设计的经营业绩进行了调查。总体而言,两种不同的依赖变量正在研究中。其中一项措施,是指在实验中的受试者要求执行两个任务(即设置闹钟和呼叫某人)所运行时间的。另一个变量是主观变量,由五个7点李克特测量。

实验过程是:1)实验前,先讲解实验内容和相关的特别注意事项,参与者熟悉这个手机操作前的仿真程序。 2)打开实验接口,并告诉用户该实验细节。3)参与者在四个随机顺序的接口条件下执行三大任务。 4)完成三个任务后,让用户写“主观因素”的问卷调查。 5)休息30分钟后,进行等3种不同的软件和硬件接口设计任务,并重复步骤3),4),和5)。实验完成后,用户完成了4种手机。经过实验数据的收集和统计分析,一般的线性模型(GLM)是用来测试受试者的年龄,运行时间和主观因素对手机界面设计和交互效应的影响。

3结论

本研究使用的GLM统计分析,探讨了年龄和手机界面设计对运行时间和方便性的影响。首先,年轻和年长的参与者(F =10.98,P <0.05)设置闹钟的执行时间有着显著的不同。年长者设置闹钟的时间(M =58.10)显著比年轻的参与者“(M =25.15)长。第二,操作系统之间的交叉和硬件接口的电子对在设置闹钟时所用的时间长短是很大不同的(F=6.95, P<0.05)。跨硬件接口(M =48.68)的设置闹钟的运行时间明显比电子对硬件接口(M =34.58)的长。第三,运行设定闹钟的时间上有一个显著的年

龄和硬件接口设计的互动效应(F= 3.86,P<0.1),其中图1的结果显示。

图1 年龄和硬件接口设计对设置闹钟的运行时间的影响

年长者用跨硬件接口(M =70.40)设置闹钟的运行时间明显比电子对硬件接口(M =45.80)运行的时间长。然而,年轻人用跨硬件接口(M =26.95)设定闹钟的运行时间和用电子对硬件接口(M =23.35)没有显著差别。

第四,年轻者和年老者在拨出电话的运行时间上有很大区别(F =6.29,P <0.05)。年老者呼叫某人的时间(M =49.90)显著长于年轻人(M= 8.60)。第五,老人和年轻人的主观能动性的差异(F =4.25,P <0.1)。老人的主观能动性(M= 6.09)显著比年轻的参与者(M =5.26)高。第六,主观便利之间的矩阵和网页软件界面的不同(F=3.20, P<0.1)。主观便利页软件界面(M =5.79)明显比矩阵的软件接口(M =5.56)高。图2显示,年龄和软性的界面设计对主观的便利性(F =7.46,P<0.05)有一定的影响。老年人的主观便利性中,软件界面(M =6.15)高于矩阵软件界面(M =6.06)。然而,年轻的参加者主观上的便利,通过矩阵式软件接口(M =5.56)高于页软件界面(M=

4.96)。

图2 年龄和软件界面设计在主观方便性的互动效应

4讨论和结论

本研究评估经营业绩的年龄和手机的界面设计的影响。根据研究结果,老年人的操作时间明显高于年轻人,充实研究成果处理老年人应用以计算机为基础的任务

[ 13][21 ]。此外,年长者用跨硬件接口设置闹钟的运行时间明显比电子对硬件接口运行的时间长。然而,年轻人没有明显差别。最后,老年人对页面的软件接口的主观方便高于矩阵软件界面,但年轻人却相反。本研究推测,随着年龄的增长,感官性能和认知能力的退化,导致对功能性能要求的降低。对老年人来说,跨硬件接口和矩阵软件界面过于复杂,所以老年人更倾向使用容易,简单,更容易理解的接口设计,如电子对的硬件接口和页面软件接口。

从本研究的结论可以作为一个有用的设计师参考。在设计适合老人的手机的过程中,需要简化的经营方式和减少操作步骤,优化性能并考虑老人的主观方便性。

大学四级作文:智能手机的利弊

Smartphone Addiction

As the development of modern technology, Smartphone has become quite popular all over the world with its outstanding functions. People can use phones to surf the Internet, update their personal micro blog, and upload their latest pictures at any place, anytime. It seems that smart phones have already become an indispensable part in people’s daily lives. However, some people are indulging in smart phones, which already have side-effect on their normal life.

随着当代科技的迅速发展,智能手机以其卓越的功能风靡全球。人们可以在任何时间、任何地点用它来上网,更新个人微博,上传自己的最新照片。看起来智能手机已经成为人们生活中不可缺的一部分了。然而,有些人过渡沉迷于智能手机,以至于影响了正常生活。

Some people, especially teenagers, are easily fall for Smartphone for these reasons. First of all, nowadays, people are under great pressure, while cell phone provides a platform for people to relax themselves. By playing mini-games, vocal chatting with friends, watching movies and listening to music, people can easily forget their problems temporary. Second, there are always something new on the phone. It is can be interesting, mysterious and various. So people are eager to turn on their phones, want to know what is happening around them. When people spend too much time on the phones, they don’t have enough chance to communicate with their friends or parents. Their attentions have been drawn away by the virtual world. Lack of good self-control, they are fragile to the smart phone addiction, while they supposed to focus on their study and work.

一些人,特别是青少年,极容易被智能手机吸引。原因有这些:首先,当今社会人们压力很大,智能手机提供了一个给人们放松的平台。通过玩小游戏,与朋友语音聊天,看电影听音乐,人们很容易暂时忘记他们的烦恼。其二,手机上总有新鲜事。有趣的、神秘的、种类繁多的信息吸引着大家打开手机,去了解周围到底发生了什么。当人们花了太多的时间在手机上时,就没有足够的机会去与朋友父母聊天沟通。他们的注意力已被虚拟世界所吸引。缺乏好的自控能力,他们在手机成瘾面前弱不禁风。他们理应集中精力在学习和工作上的。

I think people should take smart phone addiction seriously. Quitting addiction needs time and patience. People should turn off their phones, go outside and communicate with others face to face. Do more exercise and form optimistic attitude towards life! 我认为人们应重视把智能手机成瘾症。戒掉它需要时间和耐心。人们应该关掉手机,走出家门与他人面对面的沟通交流。多做运动,培养乐观积极的心态!

1) analyze the graph, and

2) give your comments on the trend.

范文1

In recent years there has been a dramatic rise in the cell phones, which are now essential to millions of people as a convenient form of communication. In 2004 the number reached 315,000,000, with an average annual increase at 57,500,000. Some people can now no longer imagine life without their cell phones. The fact that they are so popular proves that they are useful and convenient. Cell phones enable people to easily and quickly communicate with one another; wherever you are, you can instantly reach somebody. Cell phones eliminate the trouble of not being able to meet someone in person, and therefore increase business's efficiency. Mobile phones necessarily also harbor disadvantages. The radiation such phones emit is hazardous to one's health. Furthermore, if people become too reliant on the use of cell phones, our face to face skills may decline. Any new invention has its drawbacks, and such negative aspects cannot always diminish its popularity. Despite the negative effects of television, for example, the number of people who own televisions continues to grow at a tremendous rate. This is also the case with mobile phones. People won't stop eating just because of the risk ofchoking. In addition, the swift development of science and technology will likely eliminate the hazards cell phones may cause. One can safely predict, therefore, that with the introduction of new techniques, mobile phones will have more applications and become even more appealing to customers.

近年来,手机有了飞速的增长。对数以百万计的人来说,作为最便捷的通讯工具手机是生活中必不可少的。到2004年,手机的数量达到3.15亿,平均每年增长了5750

万用户。

有些人现在已经无法设想没有了手机的生活会是什么样子。手机如此普及的事实证明了它们的实用和方便。手机使人们能够简单快捷地相互沟通,无论身处何地,

都能马上联系上。可避免地存在弊端。手机发出的辐射对健康不利。而且,如果人们过于依赖手机,那么我们面对面交往的能力会下降。每个新发明都有它的缺点,但这些消极方面并不会影响它的普及。比如电视,尽管有很多负面作用,但拥有电视的人数还是继续以极高的速度增长。这种情况也适用于手机。人们不会因噎废食。而且,科技的飞速发展有希望消除使用手机所带来的风险。所以,可以有把握地预言,随着新技术的采用,手机会有更广的用途,而且会对消费者更有吸引力。

As is shown in the chart, cell phones are becoming more and more popular within China. In 2000, the number of cell phones in use was 85,260,000; in 2001, the number was 180,000,000; in 2002 206,600,000; in 2003 269,000,000. In 2004, the number is

315,000,000. From these statistics, we can see the increasing use of cell phones.

Why have cell phones gained so much dominance in our lives? There are many factors contributing to this development. Firstly, a cell phone has no wires and can be carried everywhere easily. It is smart. If you need to ring someone, you can just dial a number and the phone will connect you to the right person. It can be a great help for you to be connected with the world. Secondly, a cell phone is something wonderful that we can have fun with: news, games, music and chat through sending short messages. Thirdly, the drop in price and the simultaneous improvement in the

functions have made it possible for an average person to make use of a cell phone.

The wide use of cell phones has made them more and more indispensable in people's daily life. The many functions of the cell phone have made certain people reluctant to separate themselves from their cell phone.

这个图表向我们展示了手机在中国变得越来越普遍。在2000年,全中国的手机使用量为8526万部;2001年为1.8亿;2002年为2.066亿;2003年为2.69亿; 2004年的手机使用量迅速增加到

3.55

为什么手机会成为我们生活中的主导?有许多因素促成了它的发展。首先,手机可以无线通话,并且携带方便。它很灵巧。如果你想打电话,只须按键,就能与对方通话。它为你与世界沟通提供了巨大的帮助。其次,我们可以从手机中获取很多乐趣,比如,看新闻,玩

游戏,听音乐,发短信聊天。最后,手机迅速降价,同时其功能迅速改进,使得普通人都使

手机的广泛应用,使它已成为人们日常生活中越来越不可或缺的一部分。手机的广泛功能使得一些人几乎离不开手机了。

参考范文:

From the cartoon given above, we can observe that there are many people crossing the street. Instead of looking at the way, they are staring at their cell phones and using walking sticks to see. It is obvious that they are fascinated with cell phones while even ignore their security.

We learn from the cartoon that cell phones have been increasingly widespread in people's life. Cell phones are of great benefit to all of us. One of the most obvious advantages is that we can contact with our friends and relatives more conveniently than ever before. However, it is mobile-phones' advantages that lead some people to overuse or be addicted to them, which tends to exert a negative impact on our life. For example, overusing cell phones will reduce face-to-face communication among people. It seems that most of us enjoy the convenience of contact at the expense of interpersonal relationships. Moreover,entertaining electronic games, magnanimous information and a bewildering variety of social networking tools in mobile phones have occupied much of our time. Information distribution tools and social networking tools, in particular, have attracted all of our attention, which tempts us to keep our eyes on the screen around the corner of every second. Then, do not expect us to talk with the people around us, we don't have time! This, has resulted in a phenomenon of "alienation between acquaintances and familiarity between strangers".

Science and technology and modern tools should be served as an "angel" to improve our living standard, rather than a devil to disturb our normal life and communication. Just imagine, live one day without mobile phone, will you be relaxed? Or anxious? (279words)

参考译文:

如图所示,我们可以看到有很多的人正在过马路,他们没有仔细看路,却都盯着自己的手机并且用一根拐杖代替他们看路。很明显,他们都着迷于手机,甚至忽视了自身安全。

我们从图画得知手机已经在人们的生活中越来越普遍。手机对于我们有巨大的好处,最明显的好处之一,就是我们可以比以前更加便利地联系朋友和亲人。然而,正是手机的诸多好处导致一些人过度使用或者是沉迷于手机,而这往往会给我们的生活造成一些负面的影响。比如,过度使用手机将会减少人与人之间的面对面的沟通。似乎我们大多数人都是以牺牲人际关系来享用联系的便利性。再者,手机上得娱乐性的电子游戏,海量的信息和各种各样的社交网络个您根据也已经占据了我们很多的时间。尤其是信息传播工具和社交网络工具已经占据了我们所有的注意力,这使我们每分每秒地将目光锁定在屏幕上。那么,就别指望我们很周围的人聊天了,我们没有那个时间!这也导致了一个现象:"熟悉人的陌生化,陌生人的熟悉化"!

科技和现代工具应该是提高我们生活质量的"天使",而不应该是影响我们正常生活和沟通的"魔鬼"。设想一下,如果过一天没有手机的生活,你会放松?还是会焦虑?

Android的基础应用 英文范文.doc

Android Application Fundamentals

Android applications are written in the Java programming language. The Android SDK tools compile the code—along with any data and resource files—into an Android package, an archive file with an .apk suffix. All the code in a single .apk file is considered to be one application and is the file that Android-powered devices use to install the application. Once installed on a device, each Android application lives in its own security sandbox:  The Android operating system is a multi-user Linux system in which【手机应用英语作文】

each application is a different user.

 By default, the system assigns each application a unique Linux user

ID (the ID is used only by the system and is unknown to the

application). The system sets permissions for all the files in an application so that only the user ID assigned to that application can access them.

 Each process has its own virtual machine (VM), so an application's

code runs in isolation from other applications.

 By default, every application runs in its own Linux process.

Android starts the process when any of the application's

components need to be executed, then shuts down the process when it's no longer needed or when the system must recover memory for other applications.

In this way, the Android system implements the principle of least privilege. That is, each application, by default, has access only to the components that it requires to do its work and no more. This creates a very secure environment in which an application cannot access parts of the system for which it is not given permission.

However, there are ways for an application to share data with other applications and for an application to access system services:  It's possible to arrange for two applications to share the same

Linux user ID, in which case they are able to access each other's files. To conserve system resources, applications with the same user ID can also arrange to run in the same Linux process and share the same VM (the applications must also be signed with the same certificate).

 An application can request permission to access device data such

as the user's contacts, SMS messages, the mountable storage (SD card), camera, Bluetooth, and more. All application permissions must be granted by the user at install time.

That covers the basics regarding how an Android application exists within the system. The rest of this document introduces you to:  The core framework components that define your application.  The manifest file in which you declare components and required

device features for your application.

 Resources that are separate from the application code and allow

your application to gracefully optimize its behavior for a variety of device configurations.

Application Components

Application components are the essential building blocks of an Android application. Each component is a different point through which the system can enter your application. Not all components are actual entry points for the user and some depend on each other, but each one exists as its own entity and plays a specific role—each one is a unique building block that helps define your application's overall behavior.

There are four different types of application components. Each type serves a distinct purpose and has a distinct lifecycle that defines how the component is created and destroyed.

Here are the four types of application components:

Activities

An activity represents a single screen with a user interface. For example, an email application might have one activity that shows a list of new emails, another activity to compose an email, and another activity for reading emails. Although the activities work together to form a cohesive user experience in the email application, each one is independent of the others. As such, a different application can start any one of these activities (if the email application allows it). For example, a camera application can start the activity in the email application that composes new mail, in order for the user to share a picture.

An activity is implemented as a subclass of Activity and you can learn more about it in the Activities developer guide.

Services

A service is a component that runs in the background to perform long-running operations or to perform work for remote processes.

A service does not provide a user interface. For example, a service might play music in the background while the user is in a different application, or it might fetch data over the network without blocking user interaction with an activity. Another component, such as an activity, can start the service and let it run or bind to it in order to interact with it.

A service is implemented as a subclass of Service and you can learn

Content providers

【手机应用英语作文】

A content provider manages a shared set of application data. You can store the data in the file system, an SQLite database, on the web, or any other persistent storage location your application can access. Through the content provider, other applications can query or even modify the data (if the content provider allows it). For example, the Android system provides a content provider that manages the user's contact information. As such, any application with the proper permissions can query part of the content provider (such as ContactsContract.Data) to read and write information about a particular person.

Content providers are also useful for reading and writing data that is private to your application and not shared. For example, the Note Pad sample application uses a content provider to save notes.

A content provider is implemented as a subclass of ContentProvider and must implement a standard set of APIs that enable other applications to perform transactions. For more information, see the Content Providers developer guide.

Broadcast receivers

A broadcast receiver is a component that responds to system-wide broadcast announcements. Many broadcasts originate from the system—for example, a broadcast announcing that the screen has turned off, the battery is low, or a picture was captured. Applications can also initiate broadcasts—for example, to let other applications know that some data has been downloaded to the device and is available for them to use. Although broadcast

receivers don't display a user interface, they may create a status bar notification to alert the user when a broadcast event occurs. More commonly, though, a broadcast receiver is just a "gateway" to other components and is intended to do a very minimal amount of work. For instance, it might initiate a service to perform some work based on the event.

A broadcast receiver is implemented as a subclass of BroadcastReceiver and each broadcast is delivered as an Intent object. For more information, see theBroadcastReceiver class. A unique aspect of the Android system design is that any application can start another application’s component. For example, if you want the user to capture a photo with the device camera, there's probably another application that does that and your application can use it, instead of developing an activity to capture a photo yourself. You don't need to incorporate or even link to the code from the camera application. Instead, you can simply start the activity in the camera application that captures a photo. When complete, the photo is even returned to your application so you can use it. To the user, it seems as if the camera is actually a part of your application.

When the system starts a component, it starts the process for that application (if it's not already running) and instantiates the classes needed for the component. For example, if your application starts the activity in the camera application that captures a photo, that activity runs in the process that belongs to the camera application, not in your application's process. Therefore, unlike applications on most other systems, Android applications don't have a single entry point (there's no function, for example).
