Handheld Data Matrix Scanner on Vuforia Studio

Could an external handheld scanner be used for getting input on hololens ? If yes, could you please provide an example how it could be implemented?

Hi @PT_10006465 ,

so far I know is this not directly possible. 

Unfortunately, external devices /or usb devices are not supported in Studio yet and the usage with  drivers is not supported and probably not possible. Studio environment uses Vuforia view which could access only the internal main device camera. Indeed, the Vuforia View is an app developed with the Vuforia Engine app but it supports many devices working on different OS (Android, HoloLens, IOS) and therefore it used only general APIs which are supported on the most devices - according to
Vuforia View Device and Operating System Support http://support.ptc.com/help/vuforia/studio/en/#page/Studio_Help_Center%2Fcommon%2FViewSupportedReq.h...

The Vuforia Engine in generally supports external devices (mostly cameras) so referring to the inks on the Vuforia developer portal
• External Camera https://library.vuforia.com/articles/Solution/external-camera.html• External Camera Support https://library.vuforia.com/platform-support/external-camera 
• Creating a Custom Driver https://library.vuforia.com/articles/Solution/creating-custom-driver.html 

The question is what as  input is expected and it depends on the scanner API. When possibly you want only to evaluate the result of the scan , in this case if the scanner provides an API  to send the result value to Thingworx (e.g. Rest API)  , so a Thingworx service could be used to receive this result in the Experience Project during the runtime.

The reasons we want to use external handheld scanner are:

 

  • Data matrix scanning not supported in HoloLens.
  • Label to be scanned is a very small size - 1 cm2
  • High probability for lens damage because of some label location is not reachable for HoloLens

Is there any way to have widget with text input?

 

Are we able to  create a custom widget or manipulate/add html element for text input?

 

Thanks.
