Grammar issue

Hi, this is a text i sent to my teacher. he said i have a lot grammar problems. can you pls help me to correct?

As the world mobile goes toward Smartphone usage and many traditional models are disappeared, many new types of human computer interactions are sprung.
One of the most important tools in Smartphone devices is the typing input method.
As the peer pressure is to move toward finger stroke Smartphone devices like iPhone and Galaxy,
it is necessary to examine all possibilities in order to allow better designing and to answer the world needs.
Our paper will focus on the differences between two text input methods; touch screen based on finger stroke and touch screen based on pen stroke.
The project will look at some basic day to day typing and text editing tasks (e.g. message writing, text insertion, text deletion, text selection and etc) and examine the precision, sensitivity and the trades off between the two methods.

thanks!!!
