As people who have a Nokia mobile phone with Symbian S60 3rd operator System all know that the best video player must be the coreplayer .Because coreplayer’s function is very strong. It can almost play all the video formats except the formats of rmvb and rm .Although its function is very strong, but I don’t think its interface is beautiful or human-friendly .In a word its interface can’t match its strong function .If any other mobile player can has its strong function we will never use it. Its interface is as bellow: The picture of Coreplayer Firstly, its interface is not beautiful. It has bad color .I think the white background may be the worst choice .The white color make it seems to be too monotony and unattractive . Secondly, its interface is not human-friendly. As a video player it doesn’t has the pause button, speed button, back button on the interface. That make people feel it is not like a video player at first sight of it .The user may think that such ugly interface can’t have a perfect function, or customers may think it’s a irresponsible corporation. I think it should remake its interface again. I think it can use the windows media player for reference. The windows media player is a big success. It has a simple but beautiful interface. The interface of the windows media player is as below. 

Firstly, it can change the color of its background. I think it may use weak green. Picture of Windows Media Player That will make it more close to the nature. Or it should add the function to change the theme of the player to meet the different tastes of different people. Secondly, it must add the navigation keys such as play button, pause button, stop button, back and speed button. That will make people think it more like a player and feel more comfortable. When I told the Interface’s modified schematic design to all my friends who have a Nokia smart mobile phone, they all say that’s a good idea. They say that will make more people be fond of it and try to use the coreplayer.The schematic design will make it be widely used among the students who own a smart phone. I firmly believe if it can change it’s interface, it will be more and more popular among the user of smart phone. I wish the changed coreplayer with beautiful and human-friendly can come into the market as soon as possible.
