The Warnings !
Your I-Click is designed for PC / Tablet / phone control only, and
should not be used for a life safety applicaon such as controlling a
wheelchair or machinery.
The I-Click uses small magnets within its
construcon and although no stronger then
what would be found in headphones those
users with pacemakers should be aware and
take precauons and advice before using
the device.
Parts of the I-Click mounng system
are very small & could be a choking
hazard to small children.
Avoid leaving in direct sunlight

1 Introduction
1.1 What is a I-Click switch
An I-Click is a special switch that uses light in the invisible infrared spectrum
to detect the niest of movements from the human body typically twitches
from facial muscles. As the sensor is sensive to infrared (IR) from the sun
the I-Click is designed for use in shaded indoor areas only.
Infrared light (IR) is transmied from the sensor and bounces back from the
users. The I-Click measures the level of IR reected and can determine if
the distance has changed with great accuracy.
The I-Click can be congured to detect movement towards OR away from
the sensor to suit the users best movements.
1.2 I-Click vs a regular mechanical switch
Unlike a convenonal switch that can be pressed and held a I-Click sends a
’click’ ie a momentary transient on then o. Although, it is possible to
congure an I-Click to toggle its relay on then o based on two click acons.

1.3 Outputs
1.3.1 USB
From the USB, and can be either one of three ascii keyboard characters or a
mouse click and these are supported by most Pc/Mac/ tablets & phones
1.3.2 Relay & relay toggling
Relay output is the same as a mechanical switch. This is normally pulsed or
it can be toggled On and O, where On requires a click then another click
turns the relay back to O.
If the Relay is le on for longer than I minute it will auto clear to O.
1.3.3 Audio / Bleep feedback
The I-Click has a small sounder (bleeper) incorporated which indicates when
an output is occurring. This sound can be congured to suit the user
including being muted. See secon 3
1.4 Auto Posioning Feature
If a user accidently changes posion slightly whilst using a I-Click, the I-Click
will try to self compensates and connue to operate. However if the
movement is sucient to aect normal operaon an alarm will be triggered.
See secon 4.2
1.5 Powering the I-Click
The I-Click takes its power from the USB lead and this is required to be
connected at all mes even if a USB trigger signal is not used. An I-Click can
alternavely be powered from a USB power source such as a USB mains
adaptor or a USB Baery Power Pack such as oen used to charge mobile
phones.
Once powered the G-Click will enter its Setup State (see 1.8) and this is
released by pressing the buon once.
1.6 Freeze / Setup State
The Freeze/ Setup State allows the sensor to be accurately posioned at the
opmum distance from the users skin. Whilst in the state all outputs
are inhibited ie the I-click is said to be in a freeze state,
When the I-Click is rst powered up the I-Click will be in this state. The
centre three green leds being on, indicang the opmal distance for
the device to be from the users skin.
If the I-Click is far too close or too far away the end leds will ash
either red, for too close or purple, for too far away).
This state can be re-entered at any me by a single buon press.

3.1 Prinng the Current Conguraon
On your PC start your favourite word processor such as MS Word or
Notepad and make sure it is in focus ( ie click on the page ready to type) .
When the I-Click is frozen in its seup state (see 1.6) press and hold the
buon unl two red lids light (approx 6 seconds). The current congura-
on will then be typed into the open word processor document.
The conguraon will also be typed when the I-Click enters and leaves
the conguraon ulity.
I-Click Firmware: 0.0.0
USB Output Style: Space Bar (default)
Detecon Direcon: Towards Sensor (default)
Bleep Style: Normal (default)
Output Toggle: O (default)

www.CelcMagic.org 9
3.2 Output style (Red opons)
This congures the USB communicaon to the host computer.
It can be a keyboard character or a le mouse click.
It can also be turned o if only the relay is required.
The relay will operate at all mes and is not aected by the USB output
selected.
3.3 Detecon Direcon (Green opons)
The IR Sensor can detect either movement towards the sensor (default) or
some applicaons such as detecng from a nger nail it is useful do the
opposite and trigger from movement away from the sensor
Ie a nger moving down is more natural & would trigger yet the actual nger
nail is moving away from the sensor.
3.4 Beep style (Blue opons)
The sounder/ bleeper can be turned completely o (not recommended) or
just allow the alarm beeps. It is also possible to change the duraon of the
beep for a valid click.
3.5 Miscellaneous (Yellow opons)
This selects the behaviour of the relay output
1Relay Normal (default)
2Relay Toggles
If Toggle is selected then the st click will turn the relay on and the
white led at the top of the bargraph display will also stay lit. A
second click will turn (toggle) the relay and led back to o.
3Resets all sengs back to factory defaults
4Long Click
Allows for both the relay and USB spacebar (only) to be hold on for a
longer click allowing for beer access to some digital devices . See
secon 4.3 Long Clicking for more details

4 Operation
4.1.1 Seng Up the IR Sensor
The sensor is typically set to 1-4mm from the skin and
this mounng arrangement must be stable so that the
distance remains relavely constant during use other-
wise false triggers will occur.
The I-Click will aempt to compensate for small movements over me and
will alarm by ashing all leds with a bleep if the distance is too large (purple)
or too small (red) and manual intervenon is then necessary to correct.
The sensor is mag-
necally mounted
via a bendable stain-
less steel rod called
an I-Click Mounng
Rod (IMR) which are
available in dierent
lengths.
Typically if mounng
from spectacles the
IMR may be 100mm,
the part number
would then be IM-
R100. The IMR
parts are considered
consumables and are low cost items.
See secon 5 for full details on mounng arrangements.

www.CelcMagic.org 11
4.1.2 Seng the Sensor Distance
To set the opmum distance for from the chosen part of the body, rst ensure
that the IMR is secured by using the silver thumbscrew to clamp the IMR to,
for example the arm of spectacles (See previous page) , and aach the sensor
magnecally as shown.
Bend the IMR rod without straining the plasc ends to locate the sensor
such as it is poinng straight at the area of skin with the best movement, at
a distance of around 1-4mm. The I-Click led display will indicate
when the opmum distance is achieved.
Tips:
The cable can be pushed into the convenient slot on the black U
clamp ingprevent it from pulling the sensor from its magnec
mount.
With long IMR mounts it can be useful to wrap the cable once around the
IMR wire.

The sensor can be congured to either detect movement towards or alter-
nately away from itself. The direcon being detected is indicated by the
colour of the bargraph when in use.
Green: Towards the sensor (default)
Blue: Away from the sensor
See the Hardware secon 2
4.1.3 Seng the Sensivity
The sensivity knob should be carefully set. Start with minimal sensivity
(Knob fully an clockwise) and increase the knob unl the user reliably trig-
gers the output. If the sensivity is set too high then mulple clicks will oc-
cur

4.2.2 Using the I-Click: Run
The I-Click will display a dim background.
This colour represents the direcon to be
detected, the default is Green as shown and
is for movement towards the IR sensor to be
detected (default) . Blue is used for ‘away
from the IR Sensor’ .
As the distance changes a bright bargraph
grows.
An output occurs when the top led turns
white and a audio bleep occurs similiatnously

Some devices using IOS and Android are looking for a longer press to more easily
make selecons. To enable the I-Click to produce an occasional longer output
when required, the oponal ‘Long Click’ feature can be selected in the Yellow Mis-
cellaneous menu . See secon 3.
Tip: It is easier if the user can see the led bar display when learning to
use this feature.
When user acvates an output normally the bargraph ‘grows’ unl the top white
led lights BRIEFLY indicang that a normal output click has occurred.
To insgate a longer click turn on this feature. Now if the user controls the level
on the bargraph such as to move the bargraph up, but not suciently high that it
triggers the output to occur then the bargraph will change to yellow. Two very
short clicks will also be heard.
Yellow indicates that the next output will be a longer pulse and aer that the the
feature will reset and connue as normal with shorter clicks unl Long Click is ac-
vated again in the same manner.

5 IR Sensor Mounting
5.1 Mounng the IR Sensor
There is no right or wrong method to mount the I-Clicks IR Sensor. The I-Click will
be provided with at least one mounng system that is chosen at me of purchase.
Two types are discussed here to illustrate the principles involved, for the latest
range of opon accessories please visit the I-Click page on the Celc Magic
website : www.celcmagic/I-Click.
Standard mounts may be applied in any praccal way that works for the user and
can be incorporated in home grown soluons as necessary.
5.2 Fundamentals
When selecng a locaon on a potenal user, the muscle movement must be:
KIT1 illustrated

www.CelcMagic.org 16
1) Visible - but can be very slight
2) The user can control this moon consistently
3) No involuntary movements associated with the locaon chosen
4) The user must have the necessary cognive ability to use a switch
5.3 Choosing: Towards or
Away detecon?
By default the IR Sensor
will detected moon
towards the sensor and
this is the normally
accepted method of use.
However in this photo
the sensor is mounted to
detect slight movement oif
of the users forenger
and as the user would
expect to press down to
operate a switch then
the I-click in this example
must be congured to operate when the nger is moving away from it. See Secon
2.
5.4 Aiming the IR Sensor
Normally the IR-Sensor points directly at the skin in a at orientaon and detects
slight movement towards or away.
However it will be found that some locaons such as
eyebrow movement may not produce a good signal,
this being due to the skin moving upward on the
forehead and not signicantly out towards the
sensor. Under this condions try experimenng
with the angle that the sensor is poinng and
instead of straight try 45 degrees towards the
eyebrow from above or below.

5.5 Mounng Hardware
The standard mounng hardware is available in Kits with each kit providing the
parts necessary for a parcular style of mounng arrangement.
Kit 1: For mounng from the users own spectacle frame. As spectacles come in
dierent styles three sizes of U clamps are supplied.
Kit2: Similar to Kits 1 but is suitable for non spectacle wearing users and a special
frame is supplied with this kit that has no lenses.
Kit 3: Where the I-Click sensor is to be used to detect moment from the hand or
other area of the body
Kit 4 Headband mounted as an alternave to Kits 1 or 2
All kits use the
same basic parts
supporng a stain-
less steel I-Click
Mounng Rod
(IMR), which can be
manually bent to
the desired posi-
on.

The Hand mount Kit 3
consists of a shaped
‘ruler’ which is gently
concaved and can
generally be comforta-
bly tolerated against
the skin.
The strapping shown
is typically used for
treatment of carpel
tunnel syndrome and
oers a convenient
and comfortable
method to secure the
ruler mount.
Each user is unique and should be assessed appropriately before long term use
of this mounng arrangement.
The Ruler incorporates a U-Clamp and an
IMR mount is inserted into the U-clamp
FULLY and the thumb screw GENTLY ght-
ened to secure.
