2. About the radarTOUCH
The radarTOUCH measurement device is a rotating laser scanner. The laser is a Class
Laser and not dangerous for the human eye. The laser works with a wavelength of 905nm. It
scans over 90° and does 528 distance measurements in ca. 40ms. The measurements are
based on the Time-of-Flight (TOF) method
.
Figure 8 Working range and angular resolution
The radarTOUCH can be installed above or below every surface. This surface can be for
example a display (LCD, PDP, OLED, …), a projection screen, an LED wall etc. The
radarTOUCH is also able to make surfaces interactive, which are usually never used, to
realise some computer – user interaction like the wall of a building or a car.
Furthermore, this system can be used completely detached from any surface giving the user
the possibility to interact “free in the air”, for example with gestures. Figure 9 shows how the
radarTOUCH could be used in front of a rear projection screen. Please note that the real
measurement resolution is a lot higher than in this model which is made to give you an idea
of how to use the device.

Figure 0 shows how the radarTOUCH could be used on a stage to give the presenter the
possibility to interact with his presentation in a completely new way. Please keep in mind
again that the real measurement resolution is a lot higher than in this picture.
Figure 1 radarTOUCH used on a stage
Theoretically the maximum distance for an obstacle to be detected is 50m. If an obstacle
gets successfully detected depends on a few parameters. These are theoretical values and
the performance should be tested while planning a project.
It depends mostly on the following parameters:
» Remission of the obstacle
Remission is not equal to reflexion: it describes a diffuse reflexion.
An ideal remitter would remit the light in the same way a Lambert emitter would.
The remission must be high enough to give the detecting unit in the measurement
device a chance to receive sufficient light. The so called inverse square law describes
the fact that the remitted light is reduced by the reciprocal value of the radius. This law
makes the importance of the remission obvious.
Figure shows the minimum diffuse reflection in percent compared to the distance that
an obstacle needs to be detected. For these values the size of the obstacle has to be big
enough and is a given fact in the diagram.

Figure 11 Diffuse reflection in %
» Size of the obstacle
The measurement resolution decreases with rising distance between the obstacle and
the measurement device. This is due to the fact that the size of the laser spot gets
bigger with increasing distance.
Figure 2 shows the minimum object size with changing distance. It is important to know
that the values in this diagram are determined with the least possible remission. That
means it describes a “worst case scenario”.
Figure 12 Minimum object size
These diagrams should only provide an approximate idea of the object sizes that might be
considered when integrating a radarTOUCH and are usually more pessimistic than the reality.
In the end, only practical tests can deliver reliable answers.

3. Installing and connecting the radarTOUCH
3.1 Mechanical Installation
In Figure
3
you can see the working principle of the radarTOUCH System.
Figure 13 Working principle
You can place the radarTOUCH measurement device on the floor or you can mount it above
your interactive area, for example fixed on a truss system. The flying installation requires a
radarTOUCH mounting system.
We offer two mounting systems which are described in the next passage.
3.1.1 Deluxe mounting system
With the deluxe mounting system you can adjust the following parameters:
» Rotation angle measurement device compared to the active area
(should be 0°).
» Distance in z-direction between the measurement device and for example the
screen you are using as active area.
» The tilt in y-direction
To attach the radarTOUCH measurement device at the mounting system, use the four M5
screws (the longer 50mm screws belong to the top of the measurement device, this is where
the cables are connected) (see also Figure 6).
The mechanical adjustments require some practice but then it is possible to adjust it rather
close to any surface (~2.0cm).
