Optical touchscreen technology uses multiple optical sensors to detect the touch point, which registers the touch just before physical contact with the screen. This means that users can apply zero or light touch to the screen to initiate a response, and any input device, such as a finger, gloved finger, pen, or stylus will work.
Optical technology deployed on Elo IDS displays supports 4-6 touches (based on firmware version) and is compatible with Windows XP, Windows 7 and Windows 8 in HID mode. Support on other operating systems may require a driver, customers should confirm compatibility and availability of drivers during their testing and evaluation process.
Just like Elo Touch Solutions' IntelliTouch surface acoustic wave touchscreen technology, surface coating overlays are not used on the touch screen surface, which creates a crystal clear image. In addition, scratches on the touch surface will not affect the touch screen operation. This is important for high-use public environments such as lobbies, way-finding or kiosks.
