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.
