According to Apple Insider, the patent, published by the US Patent and Trademark Office (USPTO) on Thursday, discusses a system that will be able to transfer the force to the touch screen accurately applying the capacitive touch and infrared light sensing technologies.
The touch screen will enable the users to control different functions by identifying the touch spots on the display. However, the patent states, “it would be advantageous for the user to be able to indicate an amount of force applied when manipulating, moving, pointing to, touching, or otherwise interacting with a touch device.”
The system identifies the force and touch applying “frustrated total internal reflection” or FITR, accompanied by other capacitive sensing components. Below the touch screen’s bezel, infrared transmitters and receivers are placed. The FITR uses infrared transmit lines to measure the amount of force exerted by the finger.
The system described in the patent is strongly expected to be used in the next model of iPad.
