I have an idea for a simple android application. I am very very new to android. Just started trying out myself last week. There are three impt features that will be required but i really do not know anything about it yet. I hope some guidance can be provided to me over here. I tried googling but the result are not what i meant. Firstly, I would like to know if I will be able to capture the surface area of the contact point of the user's thumb with my application. Secondly the speed of how fast the user typed and thirdly if the user is using one or two hand to type. Please provide me any suggestions or guidance or tutorials that could help me achieve that. Thanks.
