With the Consumer Electronics Show (CES 2014) less than 3 weeks away, Interlink Electronics, Inc., a global leader in sensor and human-machine interface technologies, released a timely and relevant White Paper, “Applications of Force Sensing Technology in Consumer Electronics Devices and Systems”. Although touch sensing technologies have been available since the early 1970’s, they were used almost exclusively in industrial products during the first 20 years of their existence.
Introduction of touchpad mouse devices for laptop computers, in the early 1990’s, represented the first significant transition into the consumer electronics market. Since then, touch sensing devices have permeated a wide variety of consumer products, including mobile phones, game consoles, digital audio systems and more. Today they are an indispensable component of such systems, and are expected to proliferate into even more applications in the near future.
This paper reviews the various technologies available, and classifies them by the applications and products to which they are most suited. Particular focus is given to force sensing devices and their ability to provide continuously variable control functionality. Finally, it takes a brief look at what lies ahead for the industry.
