AMI Semiconductor (AMIS) and Tyco Electronics' Elo TouchSystems have announced that they have entered into a joint development agreement to create an integrated circuit solution. The solution will enable Elo to port its Acoustic Pulse Recognition (APR) touch technology to small, hand-held and mobile devices commonly found in consumer electronics (including cell phones, PDAs, UPMCs), industrial, medical, NAV, white goods, portable gaming, and signature capture devices.

Elo TouchSystems has selected AMIS design services to develop an audio chip for its APR technology. Elo has applied its APR sound-in-surfaces technology to launch a new touch capability in its already extensive line of touchscreens, touchmonitors and touchcomputers.

APR touch technology is based on the physical principle of recording the unique characteristics of a sound generated by a touch on a surface and comparing that to a pre-measured value, thus determining the location of that touch on the surface. Durable and scalable, APR technology combines the features of currently available touch technologies into a single comprehensive solution.

According to Ken North, Elo's director of engineering, "Manufacturers of mobile and hand-held devices will now be given a third option over the existing capacitive and resistive technologies they currently use. The advantage of APR in this arena is that it can overcome such shortcomings as finger-only input (capacitive) and limitation of stylus and lack of durability (resistive). The development of an APR IC will provide manufacturers of mobile and hand-held devices with a more durable touchscreen that works with a finger or any stylus. Such an APR IC has the potential to enable Kanji writing and to scale screen size more effectively than other touch technologies, potentially accommodating displays from 1.8-inch to over 65-inch."

"We are excited to work with Elo TouchSystems on this opportunity," said Michel De Mey, senior director, hearing and audio solutions at AMI Semiconductor. "The combination of our design and audio expertise and Elo's breakthrough APR touch technology provides an innovative, ultra-low-power, reliable solution for the expanding touch screen market."
