At present, there are two sampling ways for infrared multi-touch product. One is for matrix scanning, another is for CCD identify the infrared contact point.

The two ways have different major strength and weakness. For matrix scanning, it¡¯s is high resolution, high touch precision, and suit for writing processing. But it  has disadvantage for multi-touch. Comparing with matrix scanning, CCD identification will be more easy to do multi-touch, and it can be identify out above two points, but only disadvantage is not very accurate.

We found some products only make simple gesture recognition, for example, zoom in or out, and transfer picture(even only zoom in or out to screen). So, they are not really several point coordinate data transmition. Actually, we saw lot of beautiful video on internet for show it,but if you carefully observe it, you will find which is fact only finger touch no for real shows. This is just CCD sampling.

After long time researching, now Tacteasy had got new techology to combine the two ways of strength. So, it not only can easy to perform above two contact points to touch and very precision, but also include other strong function , for example, writing very like the truth. In a word, It is the true sense of multi-touch.

Specially, Tacteasy developing a SKD software package, it is easy to use , strong function, for example,gesture recognition,computer visual, image manipulation,act induction for multi contact points core system and multi contact points writing applying system. You only match our hardware technology with our SKD software, you can developing which you wanted multi touch products. It is so easy!

Multi-writing products on testing in our Tacteasy, we will declare it at middle of October. We will offer ten pieces of new products to a competitive company to test it.

Pls kindly pay attention to Tacteasy internal website for testing vedio:
