Highlighting barcodes with the Classic UI AR Overlay on iOS

Overview​

The AR Overlay can be enabled to display and select detected barcodes in an augmented-reality fashion.

Each detected barcode will be presented on the barcode overlay by a colored frame and text. The style of the frame and text can be customized for selected and unselected barcodes.

Barcodes can be selected by tapping on the barcode overlay or automatically by the tracking controller. All selected barcodes can be handled in the delegate methods of the tracking controller.

RTU AR Overlay

The AR Overlay is also part of the SDK's RTU UI.

AR Overlay scanning modes​

Displaying an extra layer of information in the live view is useful for a range of scanning use cases. Here are four barcode scanning use cases supporting the AR Overlay:

  • Multi Scan: Quickly scan multiple barcodes in one go, highlighting scanned codes.
  • Select Scan: Selectively capture barcodes by tapping them.
  • Find & Pick: Locate specific items with a pre-defined barcode value in a large inventory.
  • Scan & Count: Count items by scanning their barcodes.
Example app

The following use cases have been compiled into a dedicated example app. Too see the complete source code of the code snippets provided here, check out the example app on GitHub.
