A Multi Touch System generally consists of at least two 100×100 panels that are connected together by using a common connector. So, why is a multi touch screen much more expensive than a traditional laptop? The costs involved in building such a system are high. With a multi touch screen laptop, this is not a problem, as the light that is emitted is very precise and the pointing finger is used to point directly at the object that you want to target, rather than having to compensate for slow movements with the use of a mouse. Another reason is that with the typical laptop keyboard, the movement to hit a key is very precise, and the light signature emitted by the keys makes hitting them very easy. The first reason is that there is no way to point to a specific location on a computer screen without having to move your fingers in a precise pattern. Why do we need these types of technology in our modern day laptops and notebooks? There are actually two main reasons. This allows for a much larger number of inputs (from a variety of different sources) than one could get with a traditional laptop – including a camera, a stylus pen, a phone, and an Internet Explorer window. While a traditional laptop relies on computing power to operate, multi touch screens rely on the latest capacitive technology. The key difference here is the finger accuracy. What is the difference between a traditional laptop computer and a multi touch screen notebook? There is no real difference at all, other than the fact that the former relies on a mouse for input, while the latter has a light-sensitive panel as its touch sensitive screen.
