Hardware Installation Guide
In-Motions projector technology can turn any flat surface into a touchscreen. Touch projector comes in a separate dedicated device, which varies in sizes, depending on the resolution and space of display area.
Hardware installation is straightforward, but there are a few essential things you need to know.
The Kinect for Xbox 360 sensor will only work if you download the full Kinect SDK from Microsoft, Click Here. You can find out more information on where to purchase one of these sensors on our website.
Primesense OpenNI Sensor:
Primesense OpenNI Sensor software has also designed to work with the Primesense OpenNI sensors. You can find out more information on where to purchase one of these sensors on our website. From our experiments, the Kinect sensor has proven to be slightly more accurate, but your tests may vary./p>
Kinect for Windows drivers included in the installer with this product. Drivers for Primesense devices will accompany those products and may need to copy into the OpenNI folders within this software installation.
If you are using numerous sensors, then each one must be connected to its dedicated USB controller on the computer. If you receive errors relating to low USB bandwidth, then you are sharing a USB controller with more than one sensor, or have too many other devices connected. It is a hardware limitation but can easily be bypassed by trying different USB ports or purchasing separate USB controller cards.
To use the Xbox One sensor, you require the Windows adapter from Microsoft. Currently, Microsoft restricts the use of the KinectV2/Xbox One sensor to one per machine.
The software allows a level of flexibility with the way the sensor is mounted; there are a few exceptions to this and checking the following will greatly increase accuracy.
1. Minimum distance:
The sensor cameras have a minimum and maximum detection range. The sensor must be placed at least 40cm away (we recommend at least 60cm) from the touchable area. The sensor has a range of about 4 meters, (See Fig 1). It is perfectly acceptable to have the sensor mounted a distance from the surface rather than right next to it. You can also add up-to 4 sensors to extend past the 4-meter limit or increase accuracy where multi-touch is used.
2. Viewing Angle:
The Kinect V1 and Primesense sensors have a viewing angle (field of view) of about 58 degrees. The Kinect V2 sensor has a viewing angle of 71 degrees. Detection is not possible outside this angle. Once again, the use of multiple sensors can help with this limitation. See Fig 2.
3. Position Around the Surface
The sensor(s) can be placed at any position around the surface. See Fig 3. The calibration process automatically takes this into account. We recommend placing the sensor(s) in a corner, looking across the surface. This is the most accurate location.
4. Angle of Sensor:
The sensor must be mounted flat against (or as close to as possible) to the surface being touched. See Fig 4. The sensor should not be twisted or mounted up side down. See Fig 5. The sensor should only be rotated in the same direction as it would normally tilt up or down.
