Frontline Technology: Projected-Capacitive Touch Systems from the Controller Point of View
Projected-capacitive touch has grown more than 100-fold in revenue since the iPhone was introduced in 2007, and it shows no signs of slowing down. This article describes many of the design and application challenges that must be faced when integrating projected-capacitive touch into a device, with a particular focus on the importance of the controller's signal-to-noise ratio.

Display Marketplace: The State of the Touch-Screen Panel Market in 2011
Each touch technology comes with its own strengths and weaknesses, a situation that is providing many differentiation elements for touch-screen panel makers. The cost competitiveness, profitability, and customer acceptance of the different technologies will become increasingly important as competition intensifies.

Enabling Technology: The Breadth-Depth Dichotomy: Opportunities and Crises in Expanding Sensing Capabilities
A simple touch is not simple. What we think of as "touch" actually includes a variety of object-sensing technologies and an even wider variety of information that can be detected about the sensed objects. This wide range of capabilities forces developers to choose between designing once for a "lowest-common-denominator" platform (breadth) or significantly redesigning their software for each hardware capability (depth). This dichotomy threatens the future of touch computing as a platform for innovation.

Frontline Technology: Camera-Based Optical Touch Technology
Optical touch systems based on the use of CMOS cameras are typically characterized by a high degree of scalability, stylus independence, zero-force touch, high optical performance, object-size-recognition capability, and low cost.
