Table 2: Gestures
The 0xFC message indicates that a gesture event has been detected. The following gesture events are
supported (for the ZX sensor this is indicated by the ‘Y’ in the ZX column):
# Gesture Event ZX Gesture
Code
2-nd byte Comments
1 Swipe Right Y 0x01
Speed
Swipe is the simplest gestural
interaction: the reflector moves in a
certain direction over the sensor.
Speed is reported as a normalized
value between 1 to 10
1 = slow 10 = fast
2 Swipe Left Y 0x02
3 Swipe Down Y 0x03
4 Swipe Up 0x04
5 Air Push 0x05 0 The reflector moves “down” and “up”
without hovering over the sensor.
6 Hover (Enter) 0x11 Position This message is sent when a “hover”
condition is detected.
Position = 0 → Center
Position = 1 → Right
Position = 2 → Left
7 Hover (Exit) 0x12 Z This message is sent when the
reflector exit a “hover” condition.
Parameter: last steady Z
8 Hover & Move Y 0x15 Position This gesture is sent when the reflector
stops (hover) over the sensor for few
seconds, then moves in a certain
direction.
Position = 0 → Center
Position = 1 → Right
Position = 2 → Left
9 Circle Clockwise 0x21
Circular motion is sensed as a double
swipe in the same direction.
10 Circle Counter-clockwise 0x22
11 Wave (Right / Left) 0x23
A wave gesture is sensed as a double
swipe in opposite directions.
12 Wave (Left / Right) 0x24
Note: the simplest gestural device is the ZX sensor, thus it implements only a reduced set of gestures.
The gestures currently supported by the ZX sensor are marked by “Y” in the ZX column.
Note: for convenience all ZX supported gestures have a payload of 2 bytes.
