Using Digital Signature Pads in LabVIEW

Recommended Posts

Hey everyone!

I'm working on a test system right now that requires the operators to sign the test reports.  In the previous generation this was done by the print/sign/scan method.  During one of the meetings it was mentioned that getting around this requirement would be nice.  I recommended we look into a digital signature pad and see what would be required to integrate one.  I've been thinking about ordering one and just giving it a go but I thought first I'd ask and see who has done this with LabVIEW before.  I know someone has, I just haven't found the documentation online yet.  

Here's how I expect it would go:

1. The software prompts the user to sign at the end of the test.  

2. The signature pad saves the image location to the hard drive or provides it to the client through an API (any experience on how this usually works is appreciated) 

3. My software would aquire the image and save it to a named range in Excel using the report gen toolkit.  Currently my report writing tool of choice.  

4... Profit!

Does this theory match with reality?  What are your experiences?  Do you have any models you prefer to work with?  

I dug for a few minutes on this and didn't come up with much so perhaps a discussion on the subject is valuable.

 

Thanks for the help!

Tim

      I recently had a project dropped into my lap and have had a tough time finding information about it on the web.  Here is a quick outline of my current issue.
       
      I am trying to take in an analog video signal (640x480) and process the stream in LabVIEW/IMAQ/IMAQdx (end goal would be to have uncompressed video being processed).  I need to be able to have an uncompressed image to do calculations on. I am currently trying to achieve this by using an axis video server and converting the analog signal into a digital signal and finding the camera via an IP address (having networked video was requested as well...     Not a must though).
       
      My understanding is that LabVIEW takes in the video stream as mjpeg (please correct me if I am wrong) and even at the lowest compression setting mjpeg streams are still compressed pretty heavily and use a lossy compression algorithm (again correct me if I am wrong) which will make doing any reliable image processing for me very difficult.
       
      So my question is... Is there a better way to do this using any other hardware?  We will be putting the software on a pc like this, so I am unable to use pci/pci-e boards/cards but something through USB or Ethernet ports is fair game.
       
      I really appreciate any help I can get!
