Complex Gesture Detection at the Edge with Machine Learning
We now enable the detection of complex gestures at the edge, right on the MCU that is performing the touch sensing. This solution gives you the freedom to add any gesture to a 2D touchpad or touchscreen that uses one of our MCUs.
Touch Features
- Single-finger tracking
- Single- and dual-finger gesture recognition
- Taps
- Swipes
- Swipe and hold
- Rotations
- Pinch and zoom
- Water tolerance
- Noise robustness
- Ultra-low power consumption
Key Benefits
- Touch sensing, gesture recognition and application/communications code in the same microcontroller
- Graphical project designer creates code automatically
- Supported by MCUs with a wide range of Flash memory, pin count and size options
- Automotive-certified devices
- Easy-to-use, comprehensive development ecosystem minimizes your time to market
- Unified touch tuning ecosystem allows you to swap MCUs without losing momentum
How Does 2D Capacitive Touch Technology Work?
- Projected capacitive touch sensors operate by measuring the tiny change in capacitance on an electrode when a human finger or other object comes in contact with a sensor grid underneath the touch surface
- An on-chip touch peripheral is used to take separate measurements of the capacitance on all electrodes to determine the position of the finger
- Additional on-chip processing functions are used to detect surface gestures like swipes and report them to the application software
Do You Need High-Performance Multi-Touch or Large Touchscreens?
