Infrared Technology

Commonly used because of its comparatively low cost, infrared is widely available especially in large format.

How does it work? The bezels around the edge of the screen house infrared receivers and transmitters. When a finger is placed in the (invisible) beam of IR light, the finger’s position is calculated.

Suitable for large touchscreens
Also works with gloves, pens and other objects 
Fast response times up to 4 milliseconds
In theory, up to 50 simultaneous touch points
Low cost
Perfect image clarity
Susceptible to interference from sunlight and halogen light sources in particular
No object recognition, any object that breaks the beams counts as a finger
Touch response before actually touching the surface
Susceptible to dust and dirt buildup on the sensors

ShadowSense™ Multi-Touch Technology 

How does it work? Shadow sense technology is a combination of infrared invisible light emitters and optical sensors around the display. The “shadow” of an object in the infrared rays is picked up by multiple optical sensors and computed to a position.

Virtually immune to ambient light interference so it works even in very bright environments 
Object recognition and palm rejection
Perfect image clarity
Impervious to water drops
Eliminates accidental touches based on size and speed of touch
High touch accuracy and fast response times of 6-8 milliseconds
Comprehensive diagnostics and customisation using the Dashboard software
Recognises passive pen and eraser inputs and differentiates them from finger inputs
Allow the user to register either hovering just above the surface, or requiring an actual touch

High reliability and robustness

Advanced Input Recognition

Instantly differentiates between a finger, pen and eraser so that inking applications can be used without cumbersome control changes.

Recognises the shape, size and pressure of any object whether it’s a bare finger, a gloved finger or a pen.

Sensing the size of an object permits control over what is recognised as a valid touch versus an unintentional touch.

High Reliability

Unlike optical and IR systems, it provides an unparalleled degree of immunity to high brightness and changing light intensities, even working in direct sunlight and studio environments.

Will not fail if portions of the screen are blocked, or if individual components fail. This high level of reliability reduces touch screen failures that bring about unresponsive touch screens, to virtually zero.

4mm thick tempered glass covers the screen. Rugged screen that is scratch resistant.
