To use the AR-app you need a target image, and it can be found in Grindex small Pump Handbook (page 5 and 23) and in Grindex Big Book (page 23). The target images are also available for download and printing below.
To get the best experience out of the presentation please make sure you have a target image of high quality, without wrinkles or folding's.
The orientation of the image is precise; if you turn the target, the 3D pump will turn too, and you can look at the 3D-model from any angle (as long as the camera can see the target image).
Zooming in to details can be done in two ways: moving the camera closer to the target image or "pinching" the 3D-model on the display.
To be able to turn the camera away from the target image while using the AR-app, or to just stabilize the image, press the "play/pause"-icon to the left.
On iPhone and iPad we successfully have been using "Air Play" thru an Apple-TV to display the presentation wireless on a big screen or a projector in training courses or at trade shows. There are probably similar techniques available for the Android OS.
