A range of capacitive touch components from Atmel, TI, NXP, and LESENSE help provide a solution for accuracy and durability in MCU applications.

This article describes the development of touch sensing and switching techniques, using the capacitive sensing technology.

Human interfaces that use capacitive sensors for proximity or touch control are changing the way we interact with electronics.

Capacitive sensing is emerging as a popular interfacing alternative to switches and knobs in consumer electronics, front panel display applications, and many industrial and automotive sensors.

Consumers increasingly use touch screen displays, monitors, and appliances for many everyday tasks. Touch screen devices provide users with a direct, quick, and easy way to interact with a computer behind a display.

Creating a touch sensing system and a look at controllers and development kits from Freescale, ADI, IDT and Texas Instruments for use in touch-based designs.

This article is the final of the five articles in the Senses of Sensors series. However, of all five types of sensors, consumers typically use touch sensors the most continuously throughout each day while operating smart phones and tablets.

How do touch screen interface development assemblage differences translate into relative strengths or shortcomings for your next design?

This article discusses resistive and capacitive touch sensing and the applications where each is the most appropriate.

A look at touch-based technologies including projected, resistive, surface capacitive, infrared, SAW and optical imaging.

If your design has any sort of a user interface, you are probably well aware of the various types of touch- sensing interfaces that are taking over for traditional push buttons and switches.

With more computing power available in the industrial environment, there are many more options for the human interface to machines.

Touch sensing screens have added a lot of functionality to handheld devices. They can also save your (battery) life.

Capacitive touch sensors operate in noisy, challenging environments. Careful attention to hardware and software design techniques can significantly increase design reliability.

It is important for the electronic system you are using to know how near an object is to its target. To accomplish such tasks, engineers can employ a wide variety of sensor technologies, capacitive, magnetic, or optical.

Part 2 of updates to the previously published “Five Senses of Sensors” articles includes advances in sensor technology regarding touch and vision.

The proximity sensor has become a critical component as touch screen technology has rapidly evolved to become the man-machine interface of choice for a wide range of electronic products today.

Touch-based interfaces have transitioned from being a specialty feature on high-end consumer products to a common feature that consumers demand on any product, even inexpensive appliances.

obile devices seemingly all have touch screen displays and often numerous other sensors, too. Understanding the underlying technologies can help you evaluate the inevitable trade-offs in these designs.

As touch screens become more sophisticated, designing with them becomes more challenging. Fortunately the rules for good design have not changed, and there are a number of solutions out there to help you meet the challenge.
