Pen and Finger Dual Touch Mode Options for 3M™ Surface Capacitive Technology
The 3M MicroTouch System SCT3250SX extends the input flexibility of 3M Surface Capacitive Technology by supporting both finger touch and pen input. The tethered pen stylus offers handwriting recognition, signature capture, and on-screen annotation capabilities. It is an excellent solution for applications with dense menus or with detailed images too small to touch with a finger.
The SCT3250SX system can be set up in dual mode (pen or finger touch input) or pen-only mode. In dual mode, the touch screen accepts touch from both the pen or from a user’s finger, which is critical for most point-of-sale signature capture applications. In pen mode, only pen input is accepted and all other input, including a hand resting on the screen called "palm rejection", is ignored.

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.
