MGC3030/3130 3D Tracking and Gesture Controller Data Sheet
Introduction
Microchip’s MGC3X30 are 3D gesture recognition and
motion tracking controller chips based on Microchip’s
patented GestIC® technology. They enable user-
command input with natural hand and finger
movements. Applying the principles of electrical near-
field sensing, the MGC3X30 contain all the building
blocks to develop robust 3D gesture input sensing
systems. Implemented as a low-power mixed-signal
configurable controller, they provide a large set of
smart functional features with integrated signal driver,
a frequency adaptive input path for automatic noise
suppression and a digital signal processing unit.
Microchip’s on-chip Colibri Suite obsoletes processing
needs at the host, reduces system power consumption
resulting in low software development efforts for short
time-to-market success. The MGC3XXX family
represents a unique solution that provides gesture
information of the human hand in real time. Dedicated
chip family members add position data, touch or multi
touch information to the free space gesture sensing.
The MGC3XXX allow the realization of a new
generation of user interfaces across various industry
markets.

2. AirWheel
An AirWheel is the recognition of continuously-
performed circles inside the sensing area and provides
information about the rotational movement in real time.
It provides continuously counter information which
increments/decrements according to the movement’s
direction (clockwise/counterclockwise). The AirWheel
can be adjusted for convenient usage in various
applications (e.g., volume control, sensitivity
adjustment or light dimming).
• Sensor Touch Gestures
FIGURE 1:
SENSOR TOUCH
GESTURES
MGC3030/3130
A Sensor Touch is a multi-zone gesture that reports up
to five concurrently-performed touches on the system’s
electrodes.
The Sensor Touch provides information about touch
and tapping:
1. Touch
The Sensor Touch indicates an event during which a
GestIC electrode is touched. This allows distinction
between short and long touches.
2. Tap and Double Tap
The Tap and Double Tap signalize short taps and
double taps on each system electrode. The tap length
and double tap interval are adjustable.
- Single Tap Delay: A single tap is detected
when touching the surface of an electrode
first and after the hand is pulled out of the
touch area. The Single Tap is only detected
when the timing between the touch and the
release of the touch event is smaller than the
adjusted delay. Increasing the time allows the
user more time to perform the tap. The range
for the adjusted delay can be between 0s and
1s.
- Double Tap Delay: The double tap is detected
when two taps are performed within the
adjusted delay. The range for the adjusted
delay can be between 0s and 1s. The smaller
the selected delay is, the faster the two taps
have to be executed.
