The advantages of this technology are represented by the maximum protection of the glass layer that protects the technology and guarantees greater resistance to wear over time. Another advantage of these touch devices is the remarkable simplicity of use due to the excellent sensitivity of these displays that do not require strong pressures to operate but only need a slight touch. Unlike optical touch screens, it is immune to changes in ambient light, allows the detection of the amount of pressure on the touch and allows the creation of devices with all-flat shapes. The capacitive touch screen display as well as the advantages also has disadvantages which are represented by a higher cost and a lower transparency compared to the optical one.
The touch screens made with infrared technology, however, consist of a glass surrounded by a series of diodes and sensors positioned along the edges of the screen. Pulses are emitted from the LEDs to form an invisible network of light rays in front of the panel surface. When this link is interrupted by a solid object, the electronic circuit sends the coordinates to the controller. This technology has the advantage of offering very transparent screens and has excellent calibration stability. As a disadvantage, it has poor response speed to touch, problems with changes in brightness and with fingers that draw trajectories that intersect (occlusion). The positioning of the illuminators along the edges requires a frame that protrudes from the screen by a few millimeters.
The constant characteristics that marks all the D-Table collections created by Danilo Cascella are the craftsmanship and then, of course, the "Made in Italy" factor, all the multitouch tables are one by one made and assembled by the hands of Italian and specialized artisans computer engineers. All the interactive features, the multitouch application, available on all D-Table models and on the Multitouch Kit and on interactive totems are implemented using capacitive or infrared, optical technology.
