Touch and 3D Gesture ControlMicrochip’s award winning technologies cover a broad range of implementations for touch and gesture controlledapplications—from touch buttons (1D) to touch screens (2D), as well as 3D gesture control.Microchip has the solution for your user interface needs, including: Water-resistant touch buttons Cost-efficient AVR and PIC MCU-based touch solutionswith integrated touch peripheral Heavy duty touch solutions under metal High-performance 32-bit touch solutions with integrated Lower-power touch padstouch peripheral (SAMD/L series) Non-touch interaction based on hand gestures IEC/UL 67030 Class-B certified touch solutionsKeys, Sliders and ProximityUser interfaces with push buttons have several moving parts,which significantly decrease their reliability. They also requirecomplex design and assembly as well as a major investmentin tooling. Microchip touch technologies, such as capacitiveor Metal-over-Capacitive (MoC), allow you to create a highimpact user interface at a lower total system cost. Easy to use Turnkey, bus or digital I/O interface Microcontroller based Robust High SNR (Signal to Noise Ratio) IEC61000, EFT and BCI tested IEC/UL 60730 Safety Class-B supported Lowest Power Proximity sensing down to 1 μA Capacitive Sensing down to 5 μACapacitive Touch SensingHow It WorksMicrocontroller-Based SolutionA capacitor is simply two electrically isolated conductorswhich are in close proximity to one another. Theconductors can be wires, traces on a PCB or even thehuman body. The capacitive touch sensor is a copper padarea that is capacitively coupled to grounds locatedelsewhere in the system creating a parasitic capacitance.A covering plate material such as glass is used to providethe user touch surface. The introduction of the user’sfinger then produces an increase in capacitance which willbe detected by the system.Microchip offers a variety of standard PIC and AVR MCUsenabling you to dedicate an MCU for touch function orintegrate touch sensing with other application functionsonto a single MCU: 8-, 16- and 32-bit PIC, AVR and SAM (ARM M0) MCUsfor touch sensing From 6-pin to 144-pin devices Up to 512 KB Flash memory On-chip integration options include USB, CAN, IrDA,wireless protocol stack, segmented LCD and graphicsaccelerator and LCD driver for TFT/STN displaysLow-Cost mTouch Evaluation Kit (DM160227)The Low-Cost mTouch EvaluationKit provides a simple platform fordeveloping capacitive touch senseapplications using including waterresistant touch.mTouch Capacitive Touch Software PackageThe mTouch Software Package (PIC MCUs) and the QTouch Library (AVR/SAM MCUs) enable designers to easilyintegrate touch technologies into their application. It allowsthe implementation in a small dedicated controller as wellas integration of the complete application in a single MCU.2Touch and 3D Gesture ControlDownloaded from Arrow.com.

When the user applies adownward pressure on the target, the resulting deformationmoves the center of the target closer to the capacitivesensor. The change in spacing produces a change incapacitance, which is then measured by the touch controller.The target can be a sheet of metal with the Fascia markingscreen on the outer surface, a metal flashing on the backof a plastic fascia, or a co-molded layer composed of bothmetal and plastic. The spacer layer is typically an adhesivewith a cut out over the capacitive sensor, and the sensorsthemselves can be either printed conductive pads on aplastic film or pads etched into the top surface of a PCB.Application Notes Techniques for Robust Capacitive Touch Sensing,AN1334 mTouch Sensing Solution Acquisition Methods CapacitiveVoltage Divider, AN1478 Proximity Design Guide, AN1492 CAP1XXX Touch Key Controller Tuning Guide, AN2034 mTouch Metal-Over-Cap Technology, AN1325 Implementing Metal-Over-Capacitive Touch Sensors,AN1626For datasheets, user’s guides and general design information please visit www.microchip.com/touch.Touch and 3D Gesture ControlDownloaded from Arrow.com.3

3D Tracking and Gesture SensingMGC3030/3130/3140 3D GestureControllers with GestIC TechnologyThe MGC3030/MGC3130 are single-chip solutions to enable3D gesture control in almost any product, such as wirelessspeakers, radios, light switches and remote controls. TheMGC3X30 are optimized for embedded usage, require no hostintelligence or resources and come with a complete gestureportfolio. MGC3140 is designed for automotive usage.The Benefits of GestIC TechnologySimilar to capacitive touch sensing, GestIC technologyuses E-field sensing to detect gestures. Electrodesremain invisible behind the device housing, allowing anaesthetically pleasing industrial design without the needfor holes or other cut-outs typically required for cameras orinfrared-based systems. Further benefits include: Full surface coverage, no blind spots Lighting independent Build in adaptive noise filtering Only gesture solution with built-in auto wake/sleep 100 μA sleep current Low system complexity Low costsThe MGC3030/MGC31X0 output direct and immediatelyusable results—everything is detected on-chip includinggestures, approach, touch events and x/y/z 3D positions.The MGC3X30 controllers are true single-chip solutionsfor the next generation of user interface, enabling gesturebased UI applications for embedded products.Fast, Precise and RobustImplemented as a low-power mixedsignal System-on-Chip (SoC), theMGC3x30 controllers offer a rich setof smart-functional features including: 0 (touch) to 10 cm detection range Fast report rate up to 200 Hz (5 ms) Field upgradable on-board gesture suite Digital interface (I2C) and configurable GPIOsOn-Board Gesture RecognitionGesture recognition is performed on chip to eliminate thecomplexity and need for additional processing, a uniquefeature to GestIC technology shortening your time-to-market.The gesture suite gives the MGC3030/MGC31X0 controllersthe ability to recognize gestures while the rest of the systemis powered down or in a power savings mode. It is fieldupgradable to ensure your system can accommodate anduse additional gesture algorithms as they become available.Gestures6Like speech and language, everybody’s hand gestureshave a unique quality that differs in timing, amplitude anda broad range of other metrics. The integrated GestICTechnology Colibri Suite makes use of a Hidden MarkovModel for high recognition rates of various gestures.This detects the subtle difference between deliberategestures and general hand movement to limit response tounintended gestures.Approach Wake-up is primarily used to wake upthe MGC3130 (and the rest of the system) whena hand approaches the sensing area.The Wave Gesture registers small fingermovements and differentiates in the x- andy-direction. Applications include shuffle playcontrol in an audio device.Flick Gestures are available as swipes or edgeflicks in four directions: North, East, South andWest. These are typically used for commands suchas next, previous, on/off or up/down.The Hold Gesture detects a steady hand totrigger events, best envisioned as the touchlessenter key. Timing is configurable.The Airwheel Gesture is an intuitive input forup/down adjustments to levels and values. Therotations are also detected on chip.The Presence Gesture enables intelligent backlighting and in the simplest manner.Sensor Touch detects touch, tap or double tapat any of the five receive electrodes. This istypically used for selection and confirmationcommands.Position Tracking is available on the MGC3130.Touch and 3D Gesture ControlDownloaded from Arrow.com.

touch products. How It Works A metal-over-capacitive touch system uses a conductive target layer suspended over a capacitive touch sensor, to act as a second capacitor plate. When the user applies a downward pressure on the target, the resulting deformation moves the center of the target closer to the capacitive sensor.
