by Martin Cooke @ elektormagazine.com:

Microchip has announced a new addition to its portfolio of human interface solutions. The MTCH6303 supports touch panel sensors with up to 1000 nodes and 10 inch diagonals. The device uses signal processing to filter noise and provide predictive tracking of up to 10 fingers, at scan rates of up to 250Hz with a minimum of 100Hz each for five touches. The projected-capacitive touch controller provides multi-touch coordinates as well as a ready-made multi-finger surface gesture suite that can bring modern user interface elements such as pinch and zoom, multifinger scrolling and swipes to any embedded design with minimal loading on the host processor. It can also be used with Microchip’s MTCH652 high-voltage line driver to achieve better SNR in noisy environments.

When combined with the MGC3130, the MTCH6303 solution is also capable of supporting 3D air gestures up to 20cm distance from the touch panel. Microchip’s MGC3130 E-field-based 3D tracking and gesture controller includes Microchip’s patented GestIC technology, allowing user input via natural hand and finger movements in free space.

Microchip Technology have announced a computer peripheral 6” touchpad which it claims is the first able to resolve 2D multi-touch and free-space 3D gestures. To detect gestures up to a distance of 70 mm from the pad surface Microchip have used their MGC3130 single-chip gesture recognition and motion tracking controller released in 2012. It works on the principle of electrical near-field sensing. The 2D touch functionality is handled by a PIC32-based PCAP controller type MTCH63104. It handles 12 Rx and 16 Tx nodes, which are located in the centre, on the top layer of the TouchPad PCB between the 3D GestIC Rx electrodes. Microchip’s MTCH652 line driver is used to provide the necessary Tx drive signal up to 18V. The 2D touch pad allows tracking of up to ten simultaneous contacts. Besides the 2D multi-finger tracking functionality, a variety of surface gestures are implemented. These surface gestures can be used, for example, for two-finger scrolling.
