Introduction
The interaction between humans and computers is a wide area of research and practice, a study of interaction between users and computers [1,2]. In the last century, he began as a field of computer science, considered a branch of science and worried with the manufacture and design of systems for human usage all questions related to everything that interferes with those things. The user comes in the introduction to this integrated circuit so that the elements reflect what the user is doing.
This has become an important field of study, as it relates to many areas of human interaction with the computer such as interaction for educational, medical, commercial, economic, scientific and research purposes. In addition to the great interaction between people and devices in the field of entertainment and games through applications widely deployed, especially on mobile devices [3].
Mobile technology has grown tremendously in the interaction between humans and computers because it has become a major part of our daily life. The availability of (highresolution screens) makes hardware extremely useful. However, an individual's ability to utilize these devices acting a key part when it respects to software design that achieve the human-computer communication with mobile devices. To achieve ease of usage in UI of the system, and it is indispensable to confirm the quality of usage through the improvement process [4].
The problem of study is determined by the use of mobile devices in different castigations, like medicine, teaching, and sociology. Therefore, it is essential to focus primarily about how the user interaction with the mobile device. Due to the emergence of new versions of products due to the increasing need for users and ease of use. Where users are looking for new ways to develop mobile performance based on consumer desires and the ability to interact with a mobile device. The importance of the study is shown by contributing to the development of the skills and expertise of designers who are working to develop their skills through the creation of new mobile devices or development on previous devices. Smartphone applications also perform many transactions such as paying electricity bills, using maps to get a location where you want to go.

Literature Review
The subject of human-computer interaction is one of the broad areas of study and exercise. It developed as a beginning in the primary 1980s, where it began as a field of specialization in information technology, including mental science and engineering of human feature, and quickly extended to attract experts from other disciplines. And concepts. As a result of the integration of many different concepts and trends, human and computer interaction gave a significant model of the probability of merge various methods into a dynamic and creative intelligent method in human-centered information.
Where it facilitates the integration of different models to form a product model.
The evolution of human interaction with the computer after the emergence of personal computers, and became a large number of computer users, as a result of containing personal programs (interactive games, editing texts) and some platforms (operating systems, programming languages). In the late 1970s, the Knowledge Science Project was launched with the aim of clarifying systematic and scientific applications. At that time, PC demonstrated its need for hi ci, where he introduced human cognitive science and skills to meet these needs by combining science and engineering [5].
Human Processor method was a primary mental engineering method designed to support designer's implementation the rules from mental psychology.
HCI is realize as the survey of interpersonal relationship with the laptop systems and the applications them usage every day. This can range from using a PDA to downloading information about the HCI module that you may study as part of your undergraduate education, to update the credit balance on your mobile phone [6]. And It is defined as "a specialty interested with designing, testing and application of interacting methods http://www.i-jim.org used by man and related phenomena. It is the study of the interactive the user with the software and hardware computer systems [7].
The objectives Of HCI are as follows [7]: • Security: Keeping the user against dangerous cases and unwanted states.
• Users: Workers must react with computer-based models remotely medicinal tools in intensive care unit (ICU). • Data: Deny the user from creating dangerous mistakes via decrease danger of activating incorrect keys/buttons. Equipping user with wherewithal of improving mistakes. Guarantee privacy (keep individual information like behaviors and address) & safety (keep critical information like passwords, the numbers of VISA card). • Efficiency: Attention to the ability of the user to achieve a wanted aim or to carry out work.
1. Recoverability: Where the user can recover from a common error. It includes two kinds of mistake retrieval (forward and backward). In forward retrieval: the user's ability to deny the mistake; in the back-to-back: the user's ability to reverse the error. 2. Knowledge: Contributes to determining the user's knowledge of the model and matches the suitable or specific method to use the model. 3. Reliability: How the user handles or how to complete tasks in like states. And how the user addresses the input and output facilities of the system. 4. Substitutivity: Provides the user with an option or alternative to performing a task by selecting any of the available options. 5. Taskmigratability: Allows the system to perform the task that a user can perform.
Where the user transmissions several tasks to the system. 6. Perceptual ergonomics: The system can identify human opinions. The interface must have a control feature for how the user knows objects.

Implications of HCI for science, practice, and epistemology
The evolving method of integrating study and exercise is the generality significant achievement of HCI. The method was shown to be a mutual link between mental science and mental engineering. Ethnographic methods were subsequently directed to human activity, including design, technology development and customization activities. The model now includes extensive design and research practices, such as user experience and environmental sustainability. While HCI was constantly spoken as a design knowledge or as a guiding guide for creators, this was initially explained with HCI study and design as discrete contribution areas of expert experience [9].
The designers of the HCI public were welcomed in phase to support redesign it as a design system. It was aspect of this conversion, doing creating design specialties and problems that did not exist before. Like, the design of user experience and interface was not bringing in into HCI, but was between the first transfers of HCI to the world of design. Correspondingly, the examination of productive strains among imagination and logical reasoning in design requires a design area such as HCI where designs need to have interior logic, can be methodically calculated and preserved, and concurrently evokes novel knowledges and ideas. During the improvement of HCI, methodical and cognitive reviews have been intentionally adopted through a domain, via any measure, which manage intelligently and virtually. The effect has been a progressively mobile and difficult area that has continual to be more successful. This example contrasts with Cohen's view on how intelligent tasks evolve by models that are finally dropped. Thus, the continued achievement of the HCI public in touching its forward-looking task has deep effects, not only on human-centered informatics but also on knowledge theory as a whole [10].
Smartphones and their applications are among the most widely used technology tools in the society and play a vital and important role in our daily lives. The most important features used to classify smart phones and their applications are the operating system in which they operate and their applications. Smart phones and their applications rely on technology companies and their applications, Apple and Google.
The Smartphone is a mobile phone that provides more progressive computing and communication capabilities than regular mobile phones. Smart mobile phones and regular mobile phones may be a mobile phone-based mobile phone, a telecommunications service, but mobile phones Allows users to download programs, smart phones enable the user to download and use more complex applications than ordinary mobile phones [11].
Apps for mobile phones can be defined as: software designed to run smartphones or taplets. They are widely distributed in the community and play an important role in our daily lives, enabling the user to carry out his daily tasks as if on his personal computer such as browsing and using personal e-mail. These applications are available on smart phone application stores such as Google Play Store, Apple Store and others, and the development of smart phone applications and their design depends on the type of device itself [12].
Competitors compete for operating systems for smart phones, and vary from one company to another, but agree with each other to compete to meet the user's needs and needs and work on the development and ease of use. "Smartphone is a group of guidelines and directives that work with each other to manage the phone and its different components like the screen, the CPU, camera, or in other words is the relation among devices components and software applications that allow the user to accept benefit of the phone, As when we select an operating system what will determine the applications, games, screen interface and each thing internal the phone [13].

2.2
Some of the operating systems are smart phone applications The operating system consists of the program responsible for controlling and supporting the mobile device (Table 1). • IOS: Is an Apple smartphone operating system for its owner, Jobs Steve, and has pioneered the manufacture and design of computer programs in addition to other electronics such as Ipad, IPhone, Apple TV, all of which are touch-enabled and subject to constant updates, Apple Store [14].
Android phones owned by Google Inc. google Examples of its smartphones Samsung Samsung phones.
• Android: Is an operating system for Google, which supports many smart phones produced by different companies such as: Samsung and HTC, which is an open source system, has been produced by Google in 0223, meaning Android in human form, and subject to constant updates so called Each update has a different name such as Bean Gelly, Marshmello, Lollipop, and the app store is called Play Store [14]. • Windows Phone: Is a special portable operating system developed by Microsoft.
WP was released in 2010 with new key features, a completely new graphical interface that uses a design language known as Metro, and allows full integration with Microsoft services, such as Windows Live, or third-party services such as Facebook [15].
The development of mobile phone applications faces a number of challenges as follows [16]: • The incongruity of hardware utilities: One of the key challenges in mobile application development is that there are many standards for mobile platforms, and there are many smartphones that have excellent hardware qualifications like the size of screen and storage capability. • Heterogeneity of platforms: Every program utilizes its own programming language and offers various improvement tools for application development. Such as, while Android uses Java, its usages IOS Objective-C, Incompatibility between the platforms, due to the existence of different programming languages, which leads them to rewrite the application of each basic system to increase the effort and time required to market the application. If an iOS application is required, it requirements high-tech skills in Objective-C, and if an Android application is required, it must have Java experience. industrialists change the source code of the operating system to their hardware specifications. This is causing problems with less transportability from one version to another and more complex to application improvement. Repeated versions of the mobile operating system are another problem. Programmers should study various programming languages and APIs for these split systems and be constantly updated with SDK updates.
Mobile devices vary widely from desktop and laptop computers in terms of [12]: 1. Mobile devices run on battery and have less computational power than personal computers. 2. It has the ability to detect the location (GPS) and use the camera. 3. Users tend to use desktop applications for long sessions, while mobile app users tend to use them frequently, but for short sessions. 4. Quick start and response are important features for good mobile applications. 5. All of these features can be available in a high-productivity user mobile experience.
Nelson suggests that UI developers must beginning UI models to improve their systems. The overall objective of the patterns is to design a list of solutions to assistance UI designers solve difficult user interface issues.
Software architecture has adopted patterns as a means of facilitating software reuse, where reuse of the software has been extensively studied in previous literature. From checking the nature of the program, in that it demonstrates that the code is extremely monotonous and, in real, more than usual. Evidence has shown that code use again is a popular exercise in software engineering. Large and surprising icons are prone to repetition. Consequently, software use again is a common popular in software engineering [12]: The neglect of developers in the significance of user interface design is one of the main causes why users renounce the development of mobile applications and personal computer guidance. UI designers have also famous sure design challenge's over and over again by achieving the similar objective as software engineering studies to use again codes. We also look at how to reuse the UI in Android apps in 8 various classes (e.g., Shopping, Social, Finance, Weather, News, Travel, Transport, and Health [17].

Methodology

Besides, 53.3% of the users noted that the smartphones allow users to communicate with friends and family from anywhere in the world easily by simply connecting to the Internet. Even so 55% of users affirmed that smart devices are multi-purpose devices, in addition to being used as a means of communication used as a means of organization; it contains an address book, a calculator, a calendar, a voice recorder, a calendar of notes, and many other features that govern personal and professional life. About 64% of the respondents agreed that smartphones allow users to download many applications, such as games, health, fitness, image editing, music creation, and many other applications. Besides, 44.4% of the users believe that smartphone allows users to pinpoint geographic locations accurately by locating where they are and learning about routes. However, 53.3% of the users strongly agreed that smartphones allow users to watch videos and movies, listen to music, and let them download games that provide them with entertainment. Likewise, 2% of the respondents disagreed that the smartphones include advanced systems such as Android, ISO and other systems. Similarly, 81.5% of the users affirmed that there are a lot of companies that have produced many smartphones has Samsung, Apple, Huawei and other companies.

Standards to be considered in the design of smartphone applications
This section discusses the standards of smartphones applications design which users expected (Table 3). Key: SAstrongly agree, Aagree, Nneutral, Ddisagree, SDstrongly disagree From the findings in Table 3, it is evident that 49% of the users believe that the efficiency is very important because the user is looking for a systematic and accurate application in the data display in line with the development of the fourth generation of smart phones. Even so, 24.5% of the users strongly agreed that the smartphones should have innovation in its design because the user is always looking for everything that is new to escape the boredom of repetition and similarity that prevails in most smart phone applications. In addition, 45% of the response affirmed that speed is one of standard of smartphones design due to speed is a positive factor that encourages users to interact with the application over and over without boredom. While 58.9%) of the users noted waiting is one of the negative factors that always distracts users from using some smart phone applications. About 25.2% of the users strongly agreed that smartphone applications should be easy to use and uncomplicated to fit the largest number of users of all ages and interests without exception. Nonetheless, 46.4% of the users confirmed that smartphone application design companies test the application initially on a select group of users before launching it on the market officially as an experience through which to identify the advantages, possibilities and disadvantages of the application.

The disadvantages of the smart phone's applications on the use
This part focus on the users' perspective about the disadvantage of the smartphone, Table 4 shows the user response. Key: SAstrongly agree, Aagree, Nneutral, Ddisagree, SDstrongly disagree From the findings in Table 4, it is evident that 49.7% of the users believe that smartphones cause sleep problems and wake up when left beside the user asleep because the radiation from them leads to a defect in the secretion of melatonin, which is found in the brain and associated with the regulation of sleep. Even so, 18.5% of the users strongly agreed that the radiation from smartphones causes a high risk of certain diseases, the most common being cancer because they contain carcinogens that affect users. In addition, 55% of the response affirmed smart phones can cause damage, fatigue and repeated pain in the wrist, neck and hand, if the muscle pressure is caused by rapid movement when writing on smart phones. While 42.4%of the users noted smartphone, addiction caused the surfing of social websites and electronic games. About 24.5% of the users strongly agreed that smartphones may affect the user's culture and behavior as a result of incorrect information that a user may experience when using the Internet. Nonetheless, 36.4% of the users confirmed that users face very slow performance through using some types of smart phones. About 10.6% of users disagree that there are shortcomings in some companies in the testing of usability in smart phones and their applications. Beside 45.7% of users affirmed that the inability to cope with changes and developments in smart phones and their applications.

Conclusion
The idea of designing interaction between humans and computers is very rich, both in terms of the disciplines they derive from and the opportunities for research. This research was just discussing a small subset of subjects contained in the HCI. A study on the design of interaction between human and computer, especially in the field of mobile devices and applications. And some operating systems related to smart phone applications.
This area has just begun (in fact, the number of papers written on this subject has increased in the last few years), and there is much that we do not yet know about how the human mind works, allowing more user interfaces.
The results of the statistical analysis showed the importance of smart phones for users such as communication with people from anywhere, the possibility of downloading many applications, watching videos and geolocation. In addition to, the results identified the criteria that should be taken into account in the design of smart phone applications such as efficiency, innovation, responsiveness, reduce the waiting time for applications and affirmed that the importance of the application experience by some users before launching in the market. The study pointed out the main disadvantages of using smart phones such as: causing problems of insomnia, fatigue, pain, addiction to electronic games and their impact on the culture and behavior of users thus to the decline in performance.
Based on the views of the developers, the study defined HCI as science examines the design and use of computer technology, focusing on interfaces between people (users) and computers, in addition, HCI is a broad field of research, practice and development, with an interest in designing inspection, editing and manufacturing systems. Developers monitor human interaction with computers and the main focus of HCI is on usability which is mean the ease of learning. The importance of HCI focus on making computers more uses and met users' needs, as well as to improve and develop the effectiveness of computer systems and identifying tasks and problems that may face software. When designing HCI systems, developers take into account the ability of the user to recover from common errors, the system should contribute to determining the user's knowledge of the model and contribute to the user's handling of similar situations. The main challenges facing HCI are concentrated in three main elements: user, hardware, and software. In addition to, some users with cognitive deficits are therefore they the most problematic individuals when dealing with technological applications, mobile devices are evolving rapidly so there is challenge of continuous development of applications and software and data processing in different applications is also one of the most important challenges facing the use of different applications.

Recommendations and future studies
After studying the results of the study, the researcher concluded that designing the interaction between human and computer in the development of mobile phone has many benefits. The researcher recommends the following: • The researcher interested in the design of smart phone applications recommends a more in-depth study in terms of design in order to reach a good quality of applications. • The researcher is recommended to undertake a study to discover the priorities of HCI rules as perform through mobile developers. • A similar study is to evaluate websites and scholar projects and come up with a group of measures to confirm that the design is appropriate. • Making usability tests for programs, applications and websites.
• Qualify and train users with cognitive deficits in an appropriate manner to enable them to make better use of programs and applications.
