In recent yearss, utilizing of Internet has wholly changed the environment in which where we live, learn and work. Simultaneously, kids are often utilizing the Internet and all are ever accessing the online. Notably, kids have limited cognition for shoping the information what they want and more hard to seek and recover the consequences than the grownups. So, immature kids are being forced to pull off the designs that require complex typewriting, accurate spelling, advanced reading accomplishments, and apprehension of abstract constructs or content cognition that lies beyond their still-developing abilities ( Moore and George, 1991 ; Solomon, 1993 ; Walter et al. , 1996 ) . Based on Jakob Nielsen et Al. ( 2010 ) , the differences between kids and grownup in using the design are the kids use Internet for amusement although the grownup is used for communicating with people and their communities, kids normally use 12, 14 point and grownup use 10 point ( up to 14 for seniors ) for fount size, kids have slowly typewriting and hapless mouse control than the grownup who can make like as expert, kids like life and sound effects for their design but grownup largely disliked and age-targeted design is importance between kid groups but non necessary for grownup.
1.2 Investigating penchants of kids
Harmonizing to Dina Demner et Al. ( 2001 ) , kids use computing machines and Internet for different intents and maps which are depend on their like, disfavors, ages, involvement, behavior, features and wonts. The group of kids can be classified into four groups: 3-5 old ages old pre-readers ( merely memorise the informations that they learned before a twenty-four hours ) , 5-8 old ages old beginning readers ( get down to play hand in glove with other people ) , 8-12 old ages old kids ( go more concentrate on connexion between people ) and adolescents ( willing to analyse the new things but use of Internet is less than the grownup individual ) .
Presently, developers who designed for kids do non see the kids ‘s accomplishments and penchants. As a consequence, the applications may non be easy learned and used by kids who have rare cognition ( Hutchinson, Bederson, 2005 ) . Besides that, bulk of the tools available are for the expert users which are non suited for novice users like as kids peculiarly for kids who have really limited cognition in computing machine. The interactions of kids with the engineerings depend on their age degrees. Based on ( Acuff and Reiher, 1997 ) , the kids between 8 and 12 change their involvements from phantasy to world. They start to understand more abstract footings, longer footings and more complex footings. Researcher ( Inkpen, 2001 ) studied that the kids who ages from 9 to 13 like point and chink instead than drag and drop. Furthermore, ( Read, J.C. , MacFarlane, S.J. , Casey, C, 2001 ) discussed the assorted sorts of text input techniques for kids. This research is restricted and compared to the corresponding research for grownups.
In add-on, color penchant is besides one of the cardinal issues to look into the penchant of kids. Colour has a great impact on our live from early childhood onwards. Colour alters, evokes emotions, and affects our perceptual experience. Besides, preferred coloring material can increase the cognitive procedures ( Boyatzis, C.J. , & A ; Varghese, R. 1993 ) . An experiment ( Chung, H. Y. , et Al. 2009 ) implemented the color penchants among kids revealed that male childs preferred graphic colors for yellow, ruddy, and blue, and bright visible radiation tones for yellow, green, and purple. On the other manus misss preferred light tones for yellow, green, and purple and picket tones for ruddy and bluish. Design should be based on its targeted users instead than stress on treatment with users and the kids are non interested in the User Interface design guidelines ( Shneiderman, 1998 ) . Therefore, interior decorators should be focused on seeking the utile designs which will supply for kids ‘s penchants such as development, wellness, societal activities.
2.1 Why athletics of import for kids
Exercise can cut down emphasis that the kids who has emphasis, depression, anxiousness as grownup have. However, athletics, non exercising, encourages growing and contributes to better physical and emotional wellness. Sport psychologist: ( Dr. Glyn Roberts of the University of Illinois ) emphasizes that athletics is an of import thing to larn the environment for kids. Besides, athletics provides assorted sorts of maps and can achieve valuable things that can use in their life. They learn to work hard for winning, analyze how to get by with life if face with jobs, how to go on after neglecting, learn to listen, to remain concentrated, to obey regulations and ordinances and many things that can assist them to turn into mentally fitter individuals. Another benefit is emotional development which contains how to get by with winning and losing, how to seek once more if it is fail. In add-on, squad athletics besides provides the friendly relationship skills that mean if the kids want to win, he or she must assist other members to complete their portion of work and that can assist to success in their day-to-day life and besides future life. Sport provide healthy, physically and socially growing of kids every bit good as emotionally and societal accomplishments. Furthermore, the attitudes and behaviour taught to kids in athleticss carry over to adult life. Engagement in athleticss can acquire many benefits from being physically active for kids. It can better wellness, develop quality of strong castanetss and musculuss and cut down fleshiness to keep a healthy weight, cut down fleshiness to keep a healthy weight, better cardiovascular fittingness, provide friendly relationship among people, cut down emphasis and aid relaxation, better self-pride.
2.2 Sport sites for kids
Sport sites in Internet are really utile for kids because every kid can lend from its contents. Besides, it does non necessitate to hold stuffs that support for athletics and can play merely merely have computing machine and broadband cyberspace connexion and developing nomadic services. There are many available athletics sites for kids in Web. In our paper, we address some utile athletics sites for kids called hypertext transfer protocol: //www.nflrush.com and hypertext transfer protocol: //bettersoccermorefun.com. These web sites are official sites and made particularly for kids. It contains about the places for football, how to play them, information about merriment facts, acquiring advices and tips.

3. Plan a athleticss site for kids
3.1 Use of cyberspace by kids
With the omnipresent cyberspace entree, kids have more chances been exposed in the visible radiation of cyberspace and carried out assorted on-line activities. Harmonizing to Livingstone and Helpsper ( 2007 ) , the sum of kids accessing the cyberspace has continuously increased and cyberspace has become an indispensable tool for them to get information and communicate. Comparing with traditional resources, web beginning is more preferable and used by kids ( Bilal,
1998 ) . Some informations about kids ‘s web usage has been analyzed, for case, one study ( Johnson, 2010 ) investigated among kids whose mean age is 10.7 revealed that most kids prefer playing online games and sing web sites in a community topographic point like equal ‘s house.
3.2 Sports sites for kids
The merriment and larning chances that provided by the Web sites is the large concern of kids between 6 and 14 old ages old harmonizing to Baumgarten ( 2003 ) . Besides, a good site should besides see spread outing slightly extent of complexness to run into kids ‘s self-recognition and different developmental degrees ( Demner, 2001 ) . Therefore, a high quality athleticss site can travel far beyond supplying athleticss related cognition and accomplishments, really, it has much to offer to kids, for case, merriment, relaxation, opportunities of communicate and collaborate with equals and develop their involvements. This position may give a guideline to the interior decorators and assist them understand better about the users ‘ undertakings and adjust design to run into their ends.
Therefore, understanding our users, proving and maximising the grade of serviceability of the site is critical. After analysing the peculiar facets of kids and their alone characteristics, all these should been given high consideration when planing the athleticss sites. Based on the information ( Livingstone & A ; Helpsper, 2007 ) collected among Britain kids between 9-19 old ages old, it has been found that by and large male childs and young-age adolescents use the cyberspace more frequently and pass more clip on it when comparing with misss and older teens. Another widely accepted fact is that boys pass more clip in football games ( ) , therefore as the chief users of the site, the site design should provide for their favors, while at the same clip non disregarding their female opposite numbers. Thus the characteristics of male childs should be the focal point of interior decorators.
3.3 Serviceability of web sites
As the definition of serviceability ( ISO 9241 ) , it presents the “ effectivity, efficiency, and satisfaction with which specified users achieve specified ends in peculiar environments. ”
Brinck et Al. ( 2001 ) has proposed some characteristics that a successful web design should include, it should back up independent geographic expedition and communicating, promote the users carry throughing their aims in a fast, efficient and easy manner. All these characteristics can besides be considered when seeking to plan a athleticss site for kids.
Many bing surveies have adopted participatory deign with kids, which means the kids actively and straight involved in the design procedure and act as design examiners and spouses, have found productive consequences ( Read, 2002 ) . The serviceability applied scientists in Microsoft ( Hanna, L. & A ; et.al, 1999 ) have researched in serviceability testing by working with groups of kids, and have concluded several design guidelines of computing machine merchandises in the standards of activity, direction and screen design. For case, the activities provided should be interesting and represent some wages strategy to promote kids to interact with, and supportive instructions should be easy to grok. All these can be adopted for be aftering a athleticss site for kids.
Sing the inhibited reading accomplishments and comprehension ability of kids, web contents transferred through intuitive formats like life and sound is necessary. An experiment ( Kahkonen & A ; Oyaska, 2006 ) implemented among kids has revealed that kids are more likely to larn from life instructions, as they expect to research the functionality and have fun from the site. However, harmonizing to their research accomplishment, a combination with simple textual instructions is besides of import, as kids may confused and experience lose something if lone life can be shown.
3.4 Interaction and collaborative acquisition of web sites
In a study ( Jonson, 2010 ) , research workers have found that, severally 60.7 % and 62.9 % of investigated kids prefer to see web sites and play on-line games in equals ‘ houses. Allen ( 2003 ) besides pointed that the societal motive, sense of fond regard, winning friends and acknowledgment, for case, is a critical factor for athleticss engagement of kids in teenage. In add-on, football is a squad athleticss, most kids may seek online function drama games together. Therefore, amusement characteristic of collaborative acquisition and interaction of the site is another indispensable affair before get downing the design measure. Based on the research attack of a collaborative acquisition undertaking ( Ivan & A ; Michal, 2006 ) , keeping connexion among participants, entering their characters and behaviour, and so set uping efficient communicating tools for them is the premiss for explicating an effectual collaborative online environment. Merely seting this into pattern, a football site for kids may build rank strategy to pull engagement, diverse function drama games which can elicit enthusiasm, intuitive synergistic activities, in add-on, a corner for kids to pass on with each other, like treatment boards, online confab suites are besides laudatory.
4. Children ‘s online behavior
4.1 kids ‘s online seeking behavior
From the position of interior decorators, placing how kids use the cyberspace and their online behavior is important as all these things will straight act upon the design issues. Many surveies have been done in this country, for case, in one probe carried out among British kids between 9-19 old ages old, Livingstone and Helpsper ( 2007 ) have found that, the frequence and clip spent of cyberspace utilizing by male childs and young-age adolescents is much higher when comparing with misss and older teens. Another determination is that boys accessing to the cyberspace in more topographic points than their female opposite numbers.
During the research procedure of kids ‘s online behavior, Bilal ( 2000 ) has found that invalid switches ( e.g. often switching back and Forth, sing sites ) , continual iteration and minimum pilotage are the prevailing jobs encountered among kids ‘s utilizing of the sites. The chief ground has been attributed to the abstract and complex representation of the web information. In this context, straightforward icons and kids ‘s familiar metaphors can be used to relieve defeat of iterate actions and back up their efficient pilotage in the site, every bit good as a good agreement of content classs.
Harmonizing to the result released by another experiment ( Kahkonen & A ; Oyaska, 2006 ) , research workers found that due to the bound learnability of aid map, most kids seldom use this portion in the web sites. However, sing the cognitive capacity of kids and their degrees of computing machine experience, a utile aid map is necessary and it is a critical portion for their credence of a athleticss site. Therefore, for this particular group, the aid portion should be provided in a directive and intuitive manner, long and boring texts, abstract constructs, equivocal classs should be avoided. Besides, effectual existent clip aid is more helpful.
4.2. Engagement of Parents
Parents ‘ engagement is really of import for kids, harmonizing to the Eccles ‘ expectancy-value theoretical account ( Eccles & A ; Harold, 1991 ) , parents influence their kid picks by supplying differential degrees of support for activities. They besides proposed that the degree of support is based on outlooks of the likeliness that their kid will be successful in that country, and the personal beliefs about the value of success in that sphere. The grade of engagement of parents in their kids athletics activities is besides of import. Most of the parents under involve and most of the parents over involve in their kids activities. Under engagement means parents watch on out of boundss and they do non actively take part in their kids plans. Over involved parents overly involve in the running plan of their kids. They emphasize on winning and actuate their kids to acquire success in their running plans. Parents ‘ engagement in their kids sport make the kid to acquire competitory advantage, the kids can actively affect and can make merrily their activities with the support of their parents.
( include characteristics for the engagement of parents, instructors, synergistic games, information the site provided )
5. Design Principles for Children
Since interior decorators design the system, they must cognize clearly “ Who are the users utilizing the system? ” If the system is for assorted users who have different cognition about it, they need to concentrate on from different position like what are the user demands and involvements depending on users ‘ profiles and characters. ( kids )
Norman ( 1988 ) defined user-centered design as “ a doctrine based on the demands and involvements of the users, with an accent on doing merchandises useable and apprehensible ” . He added that easy to understand and easy to utilize of the merchandises are indicating out the user to allow them cognize what to make and the user can clearly understand what is traveling on. Harmonizing to the Rubin ( 1944 ) , user-centered design is techniques and processs for planing useable systems with the user at the Centre of the procedure. “ User-centered design rules place increased attending on developing merchandises that are easiness of usage and easiness of understand by concentrating on the user throughout the design procedure ” ( Dumas & A ; Redish, 1993 ; Eason, 1988 ; Gould & A ; Lewis, 1985 ; Shackel, 1991 ) .
If users are aged, text fount size should be larger than usual as they can non see the little fount size clearly, voice end product should be provided more longer than every bit usual or alternatively of voice end product, text end product with big text fount should be used as the aged may be lost in hearing.For users with disablements, the system interior decorators need to utilize more flexible computing machine package in order to back up particular tools for them. For low vision or blind users, voice end product should be provided alternatively of message end product. For the users who have problem in manus map, utilizing mice and trackballs can be a job for them. Alternatively of utilizing these input devices, address acknowledgment device like voice input can work out the jobs for handicapped kids.
There are many of import interaction design rules and there are many manner to use those rules. As our paper focuses on kids, we will depict some of the rules and point out what interior decorators should take into history when planing the interface design for kids. Harmonizing to the ( Heim, 2007 ) , two chief classs can be used to show the rules in a systematic and structured manner: viz. effectiveness rules and efficiency rules. He defined efficiency as “ a design that enable users to carry through their undertakings in the easiest and quickest manner every bit much as possible without holding to make excessively complex or immaterial processs. ” Efficiency and effectivity are the rules that support serviceability. Harmonizing to the ( Usability ) , the term serviceability means “ The degree of easiness with which people can use a peculiar device in order to achieve and increase serviceability ” . There are many design rule that are applied in human computing machine interaction. There are three chief design rules which support serviceability such as learnability, flexibleness and hardiness. Under each of these classs, there are many sub rules that affect them ( serviceability ) . Among these rules, the rules that are required for kids will be discussed.
Learn ability is the primary end of the user interface design and it is the really of import design rules for kids. It they do non cognize clearly how to utilize the system and if it is really hard for them to utilize, they can acquire confusion and they will non utilize this system any longer. For illustration, if excessively many chinks are required to finish a undertaking, kids can non memorise at one time and it can acquire them confused. Following clip they visit back, they will non be certain how to travel through to finish their undertakings.
Responsiveness is besides one of the design rules in which the response clip of the system should non take long as users are kids. If system response clip is slow, they may believe that the system can non supply what they want and it can non work decently.
Childs can non memorise many things at one clip like the grownup. They can memorise good merely one thing at a clip. For illustration, when put ining the package, many stairss are required to complete. Users need to snap on “ Following ” button to travel frontward and need to take location to put the installed package ‘s icon. After all the stairss have been done, users need to snap “ Finish ” button. Software installing procedure should non be different. It should be consistent. If installing procedure for different package is non the same, it can be jobs for users to memorise what should they make for this package to put in and what should they execute for other package. If the installing procedure is similar for different package, users can foretell how should they travel on by naming memory on past interaction history.
As the focal point users are kids, the interior decorators should cognize the features of kids and should plan the site to let them easiness of usage and should supply required functionality. From the illustrations of Heim ( 2007 ) , the design for a pulling plan should recite all of the tools required to make digital drawings, another illustration is that in a web site, all the information must be provided that are required by the visitant in order to carry through his or her ends.
For the kids who are less than five twelvemonth can non read the instructions in the signifier of message. Interior designers need to see this factor. Alternatively of exposing direction in the signifier of message, sound, picture, life should be used to allow them cognize what should they make to finish their undertakings. For younger kids instead than older kids, Sears & A ; Jacko ( 2008 ) stated that “ To extinguish the demand for mouse clicking, the pointer is transformed into a large xanthous star with room for five little stars inside it. As the mouse is held over a mark, the little stars appear one time at a clip. When the fifth star appears, it counts as snaping on that mark. If the kid does snap, the procedure merely moves faster ” . For the grownup, double-clicking is non a job for them. For the childs, they do non cognize the action of double-clicking. Single click action should be provided alternatively of dual clicking.
The followers are design issues for kids that should be considered when planing the system for kids.
Multiple pilotages should be avoided because it can be a job for kids and they can acquire confusion on it.
In athletics sites, if text font size of guideline instructions such as regulations and ordinances for each athletics is 12, they can non concentrate on it. So, text fount size should be larger than every bit usual.
Youngest childs do non cognize how to scroll up and scroll down. This is the large job for them. Alternatively of utilizing scrolling, multiple pages should be used.
Radio buttons and checkboxes should non be used as they do non hold ability which option to take.
Search box should non be provided. They do non cognize how to seek and they are slow in typing. Alternatively of hunt box, the needed maps should be put together on the screen.
