5 Functional Description
Gesture Definition
The implemented control logic recognizes the follow-
ing gestures:
• Awareness -> An object (e.g. a hand) enters the de-
tection zone.
• Tap -> A quick movement in the direction of the
sensor back and forth similar to pushing a virtual
button in the air.
• Time Select -> Hover in the detection range for a
certain time.
• Wipe -> A movement horizontal to the sensor sur-
face with a certain speed.
• Proximity -> A movement with continues speed in
direction to or from the sensor.
System States
The following states are possible:
• Off -> After power on the devices enters the OFF-
state.
• Search Light -> The lamp shines with a brightness
of minimum PWM duty cycle.
• On -> The lamp shines with the adjusted bright-
ness.
• Proximity -> The lamp shines with a brightness in
between 0% and 100%. Step size is 0.4%.
• Acknowledge -> Short indication of a status change.
If ACK_DIS is not set to high the indication is shown
by a variation of the brightness. If the brightness is
< 50% it will increase and if it is > 50% it will de-
creased.
Control Concept
The control concept is based on three main procedures:
This indicates to the customer "I am ready" and helps to
get a feeling of the detection zone. Also it provides the
possibility to have a glimpse to the surrounding area.
By setting the input SEARCH_DIS to VDDIO the change
of the PWM output is disabled.
Switching On and Off
The "Tap" gesture is acting like a toggle on/off switch.
If the lamp is "On" it will be switched off and vice ver-
sa. Between two taps the detection zone has to be left.
The same function can be realized by a wipe.
Proximity and Acknowledge
Once the lamp is switch on it can be adjusted to any
desired brightness. With the "time select" gesture the
status "dimming" will be entered and be confirmed be
an "Acknowledge".
Now the brightness of the lamp follows the hand. The
closer the hand the brighter the lamp shines and the
farer away the darker it will be.
Leaving the detection zone for a certain time dur-
ing dimming will stop the procedure and the previous
brightness before the "Time Select" will be set.
The dimming procedure is ended by a second "Time Se-
lect" and will be confirmed again by an "Acknowledge".
That brightness will be kept until the lamp is switched
off or a dimming procedure is started again.
Before starting the next procedure the detection zone
has to be left.
The confirmation via the "Acknowledge" at the PWM
output can also be disabled by setting the ACK_DIS to
VDDIO but is still be indicate at the pin ACK.
Search Light
If the lamp is in OFF state and an object enters the de-
tection range the lamp shines with a brightness of min-
imum PWM duty cycle. As soon as the object leaves the
detection zone or it stays there > 3s the lamp is turned
off. In the case the lamp is in ON state "Awareness" is
notified but there is no further reaction from the lamp.
Overall this represents a state of the art gesture con-
trolled input device. Field-tested, reliable, suitable for
many products and optimized to be implemented in
lamps, the E527.16 opens the door to a new intuitive
user interface - all of this under the same conditions as
a standard switch.
Elmos Semiconductor AG reserves the right to change the detail specifications as may be required to permit improvements in the design of its products.
