3M™ MicroTouch™ System DST2270DX

The 3M MicroTouch System DST2270DX offers a chemically-strengthened glass, stylus-independent touch solution with fast-accurate-repeatable response and operation unaffected by contaminants, static objects or other touches on the screen. The DST2270DX system is ideal for large-format LCD displays used for interactive digital signage and point-of-information applications. Available for 32", 40", 42" and 46" display sizes. 3M™ Dispersive Signal Technology (DST) is poised to become the touch technology standard for large-format interactive displays. Traditional touch technologies detect "touch" by interrupting acoustic waves, optical fields or infrared light above the surface of the touch screen. What's different about 3M DST is that it precisely calculates touch locations by analyzing the bending waves within the glass substrate that are created by the user's touch. This allows for fast, accurate, reliable touch performance that is unaffected by contaminants, scratches, or static objects on the screen, as well as enabling stylus support and multi-user capability.

MT7 Gestures

MT7 Gestures allow customers to use prebuilt software libraries to add intuitive gesture recognition to their touch applications. This application program interface (API) incorporates "single finger gesture recognition", as well as a programmable "radial menu" feature that allow developers to enhance their user interface with intuitive touch features. These four libraries are included in the MT7 Gestures API: •MT7 Trace collects user touch actions into traces, each representing a single touch down, drag, and lift off sequence. •MT7 Stroke takes a trace and matches it against an applicationdefined collection of reference strokes. Based on the match, the application determines what action is intended. •MT7 Radial presents a radial menu (a.k.a. pie menu) for the user to select an option that the application responds to. •MT7 Box Tool takes one or two traces and monitors their position, returning any change in distance or angle between a trace and a reference point or another trace.
