Touch Technology Enhances Large LCDs January 2005 Issue Published Date: January 19, 2005
With the rising popularity of larger, 30" and 40" LCDs with touch screens, the company’s Dispersive Signal Technology (DST) enables creative, multi-player gaming applications such as table games, bar top games, and giant slot machines. Compared to standard approaches that recognize touch by the interruption of electrical fields, acoustic waves, or infrared light, DST recognizes touch through vibrations made to the substrate. By measuring specific vibration energy, it eliminates issues with screen contaminants and surface scratches. The technology also employs enhanced palm rejection, allowing accurate touch recognition while an object rests on the screen. The substrate can be glass, tempered glass, glass integrated with the company’s Vikuiti films, or acrylic. For more details, call 3M TOUCH SYSTEMS INC., Methuen, MA. (866) 407-6666.
