1. Introduction
The Tactonom™ Reader enables blind people to understand graphic information in a
simple and playful way. This is achieved by explaining tactile structures with audio
information.
Theseexplanationsrefertotheelementthattheuserfeelswiththengertip.
Technically, information is read out with pinpoint accuracy by means of camera-based
ngerrecognition.Ifthereisinformationunderthenger,itisreadout.Thisopensup
a wide range of possible uses:
The Tactonom™ Reader combines tactile content with precise explanations. For this
purpose, tactile documents are placed on the tactile surface of the Tactonom™ Reader.
Additional content is loaded via the QR code attached to the documents.
The prerequisite for working with the Tactonom™ Reader is the existence of the
documents created for the Tactonom™ Reader.
These documents can be:
●Swell paper
●Braille-Printing
●3D-Printing
●Thermoform
●Education: At school, in training and during studies
●Mobility: Surroundingplans,floorplansandnetworkplans
●Participation: Access to a wide range of graphical information
●Rehab: Supportforthetransitiontothetactileworld
●Games: Interactivegamesofallkinds

surface. For this purpose, the Tactonom™ Reader remains switched off.
Please gently guide the camera arm upwards until it locks into place. This is done at
an angle of approx. 60 degrees. The engagement can be recognized by a distinct
clickingsound.Thecameraarmisnowxedataxedangletothecamerabase.
The camera arm must be lowered after each use and before each user change to
prevent the user from bumping it.
On the back of the camera base there is a round green head. When this button is
pressed, the camera arm lock is released.
When lowering the camera arm, the release button at the back of the camera foot
must be pressed with one hand. Use your other hand to guide the camera arm.
Please be careful not to pinch your other hand when lowering.
When using the Tactonom™ Reader, avoid excessive rocking movements of the
upper body, otherwise the camera head could be touched.
Important:
The position of the camera is of decisive importance for the proper functioning of the
Tactonom™ Reader. Therefore, only gently fold and unfold the camera arm.
Do not move the camera arm during operation. Please be careful never to lift or
transport the Tactonom™ Reader by the camera arm.
2.2 Unfolding the camera arm

To operate the Tactonom™ Reader, it must be connected to a power source.
The power jack for the Tactonom™ Reader is located on the rear left side in the recess
of the housing. The device may only be operated with the supplied power supply unit.
In case of loss, only use a power supply explicitly approved by the manufacturer.
Please contact the customer service for this.
Please make sure that the cable is not under tension and that nobody can trip over
the cable.
Before disconnecting the power source, the device must always be switched off,
otherwise the electronics may be damaged. The Tactonom™ Reader is switched off
via the „Shutdown“ menu. Please wait at least 2 minutes after shutting down the
device before disconnecting the power supply from the mains. You can hear the
successful shutdown by the switching noise of the relay.
2.3 Connecting to a power source
ToputtheTactonom™Readerintooperationforthersttime,pleasesetupthe
camera arm and place the supplied „short introduction“ graphic on the base surface.
To do this, gently press down on the clamping bar at the back of the device provided
for this purpose on the right and slide the graphic under the clamping bar. Then align
the graphic on the front side and make sure that it does not protrude on any side.
After alignment, press the large round key on the left side of the keyboard (Enter).
Please remove your hands and all objects from the key surface while the Tactonom
Reader is starting. The camera requires an unobstructed view of the QR code (back

To load new graphics, a WiFi connection is required, as the Tactonom™ Reader
combines tactile information with digital content that is initially located in the cloud.
To access the internet, the device requires the name of the WiFi network and the
associated password. This can be set up as follows:
2.5 Connecting to a WiFi network
▪CreateanewtextleonyourcomputerwithUTF-8
 encodingandnameit„wi.txt“.Todothis,itisbesttouse
the „Editor“ program on Windows or „TextEdit“ on the Mac.
The encoding is set to UTF-8 by default and can be
changed in the „Save As“ dialog on older Windows versions.
On the Mac, the text must still be converted to plain text
under the „Format“ menu.
▪Insert the text according to the following example:
Name of the WiFi network
Password
▪Replace „Name of WiFi network“ with the name of the WiFi
network and „Password“ with the password of the WiFi
network you want the Tactonom™ Reader to connect to.

Place a graphic on the touch surface.
Clamp the graphic with the clamping device, which is located at the rear edge of the
touch surface and covers the entire width. Make sure that the graphic does not
protrude laterally and is aligned with the front edge.
Graphics that protrude above the touch surface are not suitable for the
Tactonom™ Reader, as they cannot be detected by the camera. Documents that are
smaller than the scanning surface should be centered.
Ensure that the camera has a clear view of the documents. To do this, remove your
hands completely from the surface.
Make sure that the Tactonom™ Reader is connected via WiFi and that this ensures
access to the Internet.
Also make sure that the Tactonom™ Reader is connected to a power source. You turn
