Troubleshooting Guide
1. Hardware Installation
Connect the sensor (interactive unit) with the supplied USB cable to the PC. If the cable
is not long enough (max. 5m), extend the length with a repeater cable. This can be also a
USB hub, which repeats the signal. If required connect
maximum two sensors to a hub. Use the backside ports of the PC.
2. Problem Detected
If the drive could detect a problem, one of the following dialogs will appear:
A) Connection Problem
The driver is not able to receive data from the sensor. Please check your USB cables,
reconnect the sensor or try a different USB port on the PC.
B) Calibration Problem
The calibration ­ Automatic or Manual ­ has failed. If the Automatic Calibration failed,
make sure of following conditions:
1. No obstacles like hanging cables, duster are on the projection area or in front of
the sensor, which could block the view. You can check this using the “Sensor
Viewer”.
2. The room is not “too bright”. The sun or other strong light sources must not
shine directly onto the projection area washing out the image.
3. The projector has enough brightness. The projection should be well visible for
the human eye.
4. The sensor can “see” the full projection area and is not tilted or occluded. See
“Sensor Viewer” to check this.
5. There are no windows, dialogs or other programs hiding the displayed calibration
pattern.

C) Disturbance
The driver removes any static disturbance like sun shining onto the board. If the
disturbance is not static, however, the driver is not able to remove. Close the blinds of the
windows and avoid direct light on the projection area. Indirect light is ok.
3.
The Calibration Is Off (offset)
If the stylus has not approximately the same position as the mouse cursor, but it had
before, the hardware installation has moved physically or the ratio of the screen
resolution has changed. Recalibrate the sensor.
4.
Random Clicks
Random “mouse clicks”, which are not caused by the stylus are due to disturbance.
Refer to point 2.C) “Disturbance”.
5.
Sensor Viewer
This tool will show you the actual view of the sensor onto the projection area and helps to
diagnose problems. You will find the tool after the installation of the driver in the Start
Menu (or Launch Pad). Make sure you have started the driver once before using this tool.
The driver will setup the sensor.
6.
Edge Blending
You can connect up to four sensor to a PC and use it with four projectors. Make sure to
use a PC with good performance (like quadcore CPU and at least 4GB of RAM). Refer to
“1. Hardware Installation” for setting up the sensor. Automatic Calibration is supported
and recommended in this mode. After the calibration don’t change the hardware setup ­
don’t change the USB ports and don’t move the sensors physically.
Supported Edge Blending Software
Following software was tested and is supported:
1. Scalable Display
2. ImmersaView
7.
Stylus Input Is Not Working With Specific Software
The Stylus is giving “Touch” input to the Operating System (Windows only). Some
software is not supporting this. Switch in the calibration menu to “Mouse Mode”.

Offset in writing with Windows 8/8.1/10.
Sometime there is offset while using EyeRIS even when calibration is perfect. This can happen when there is mismatch between Windows resolution and Projector resolution. There are two ways to fix this problem
A) Offset fixing with EyeRIS Software
B) Offset fixing by changing resolution scaling
