Imager- vs. sensor-based interactive technologies

Which is best for your large-format display?

Are you interested in an interactive display for your organization, business, school or meeting room? Let's compare the two most common types of interactive technology used for large-format displays—imager- and sensor-based—to see which is best for your needs.

Imager-based interactive technology, also known as 'optical', uses one or more cameras to detect touch. The camera(s) may be located behind the display or in the corners of the display.

Imager technology works best with touch displays that have few simultaneous users—one or two is ideal, with no more than four—and environments with low ambient light.

Things to consider:

Sensor-based interactive technology uses sensors and invisible light beams (created by infrared LEDs) positioned around the display to detect touch. Sensor software translates users' touches—taps, double-taps, flicks, pinch open, pinch closed, etc.—into real-time commands.

Sensor technology is designed to handle large-format displays, and multiple simultaneous users. Touch screens with sensor technology, especially if the sensors are located only along the top of the display, are capable of performing with high accuracy and fast response times in high ambient light conditions.
