Hall position encoder-based touch surface

We can note that in these days touch screen technology began to flourish and it is more widely used both in hardware and in different applications. A touch screen based interface is beginning to be a basic requirement in almost every mobile appliance, and at the same time demand to equip other products with this technology is on the rise. Today´s state of the art technology is represented by the resistance and capacity based sensors for touch screens but we have seen other devices based on numerous other principles in various applications. Each principle has it´s own advantage and disadvantage that limits the field of use. This makes it a popular field of research with good market expectations which all add up to the continuous development of touch screens. We will present a method, which takes a new approach on how to build touch surface/screen. The essence of this method is based on encoders using the Hall-effect, which is also a new field of application for these sensors. This method is very cost efficient for producing touch screens by simplifying production regardless to the size of the screen. Due to the fact that this method is new in my paper we focused on finding the most optimal realization as well as determining the circumstances of reliable functioning. We will show the tests and results we have up until this point and attempt to give an overview of the advantages and disadvantages.
