Maximizing Touchscreen Performance by Pairing Powerful Circuitry with Intelligent Software

Capacitive touchscreens have become the dominant user interface technology for smartphones and tablet computers, and are being rapidly adopted in many other device categories. Product designers who want to include a capacitive touchscreen in their device need to satisfy a large number of requirements simultaneously. When these requirements conflict with each other, designers have always had to endure painful trade-offs in the quality of their design: “Should I compromise on the responsiveness of the screen to improve robustness to noise?” Some touchscreen controllers rely on a hardware-centric approach to overcome these issues, achieving noise robustness at the expense of performance and design simplicity. More sophisticated touch controllers combine novel hardware with intelligent firmware, enabling them to meet all of these requirements without compromises. Designing a Touch Interface The touch input system is one of the most crucial parts of the user interface in today’s consumer devices. So, the design of a high-quality touch sensing system must start by considering the user experience. Some of the key criteria are listed below. Responsiveness Consumers expect an instantaneous reaction as they move their fingers around on a touchscreen. A good touch controller enables this by sending a very rapid stream of update messages to the operating system so that the application always knows the current finger position. The number of updates per second is called the report rate.
