¿InfraRed o ShadowSense? Which touch screen technology is most suitable for each business?

Panasonic analyzes these two technologies, that are integrated into its range of professional multi-touch screens to meet the needs of each company and application.

Interactive multi-touch screen technologies Panasonic can be used in collaboration and byod environments, like classes, meeting rooms, of conferences, workshops, etc; as well as in complex environments to interact with assistants or visitors in stores, transportation and live entertainment, although it is necessary to know which technology -InfraRed or ShadowSense- is the most appropriate.

Pros and cons: InfraRed technology

Widely used due to its comparatively low cost, InfraRed technology is frequently used in large format touch equipment. The bezels around the edge of the screen contain infrared receivers and transmitters, so that when you place a finger on the ray (invisible) infrared light, its position is calculated.

Screens with InfraRed technology also work with gloves, pens and other objects, with fast response times of up to 4 milliseconds, offering perfect image sharpness and, in theory, up to fifty simultaneous touch points.

As negative points, This technology is especially sensitive to interference from sunlight and halogen lighting sources; does not distinguish objects, so anything that interrupts the path of the ray is considered a finger; offers touch sensitivity even before touching the surface and accumulation of dust and dirt on the sensors is common.

ShadowSense multi-touch technology

For your part, ShadowSense technology is a combination of invisible infrared light emitters and optical sensors distributed around the screen. Several optical sensors capture the 'shadow' of an object in infrared rays and a position is calculated.

Other advantages are that it is practically insensitive to interference from ambient light., so it works even in brightly lit environments; Features object recognition and palm rejection, plus eliminate accidental touches based on their size and speed; offers high touch precision and fast response times 6-8 milliseconds.

Just like previous technology, image sharpness is optimal, Although ShadowSense adds customization and complete diagnosis through the Dashboard software.; recognizes passive pen and eraser input and differentiates it from finger input; allows user to register, either by passing your hand over the surface or by touching the screen, and is resistant to water drops.
