Applicable product type


Inherent Multi-touch Gesture Recognition Feature

Rather than having the computer OS do all the work, T3Kseries recognizes the characteristics of the touch and sends the corresponding command to the computer. It, therefore, results in action that is not dependent on the computer OS but on the compatibility of the existing application.

Application developers of various operating systems can directly access and use the needed information from T3Kseries, thus making application programs that are independent of the OS.

Action Profile

The T3K Touch Sensor classifies gestures into a bundle and this bundle is what we call Action Profile. There are five Profiles in all and users can select which Profile to use thru Touch Gesture.

Selecting "Gesture" from the list provides one with the screen; one can make a connection between a certain touch gesture, an action performed with a finger, multiple fingers, or a palm, or to a certain mouse button, a keyboard button, or a combination of a mouse and keyboard buttons.

The T3K series support multi touch function without any OS specific touch and it can use the multi touch at windows7, windows8, MAC OS and Linux either OS dependent multi touch gesture or T3K provided own touch gesture.


Equipped the device with a 2 dimensional image of what the camera module on each corner views so that the technician has the tools and means to track a problem if the need arises.
