On mobile devices in particular, scanning QR codes is a quick and easy way to navigate to a URL. When Oracle Digital Assistant runs on the web as a messenger using the Oracle Web SDK, users can scan a QR code to display a launch option or to save the information contained in a code.
This article explains how to integrate QR code scanning using the on-device camera (or the camera attached to a device) from Oracle Digital Assistant. If a device does not have a camera, then this sample displays a simple alert.
Below sequence of images show the sample you can download for this article. You simply start by typing 'hi'.
Click on the QR code to start the scan. Most likely your browser will prompt you to grant permission for accessing the camera. Please allow this action to continue with the demo
Next, hold a QR code in front of the camera
When the code could be read, you see the following screen to press the button in.
As you can see in the image above, the sample displays the scanned URL (Wikipedia in my test). This message actually comes from Oracle Digital Assistant.
Download Sample
Download and import the sample skill into Oracle Digital Assistant. Open the channel configuration and expose the skill on an Oracle Web channel.
Download the index.html.zip file and unzip it. Copy the index.html file to your sample directory (the same application that you get when downloading the Oracle Digital Assistant Web SDK)
Start the index.html file and run the demo. Make sure you configured access to the web channel for the Web SDK.
