    • Import touchscreen signature from raspberry Pi to tracker

    Posted by Klaus Lindow posts: 22 Germany

    Hello,

    I am planning to borrow room keys or tickets for public transport in a rehabilitation clinic. The basic configuration of a tracker and the linking of trackers (patient, key number and ID of the ticket) are no problem. Now to the question:
    I would like the borrower to confirm receipt of the key with a signature on a touch screen on a Rasberry Pi. The image of the signature should be imported into the corresponding tracker entry as automatically as possible. We use key chips in the house, perhaps confirmation by placing a chip on a reader would also be possible.

    Does anyone have an idea how this could be implemented?

    Service personnel and the hirer do not work on the same machine! I sit behind the reception and the lender only has the touch screen at his disposal.

    Otherwise the Ras Pi serves as a kiosk system.

    Hi Klaus

    Sounds interesting, does the Pi touch screen application offer any sort of web services? If so Tiki can quite nicely use data from them and can include that in a tracker field as documented (slightly) here Webservice tracker field

    Hi, Jonny,

    thank you for the prompt reply. The idea is of course that the Raspberry displays a Tiki page in the browser (Firefox). That means the Tiki should provide exactly this function on the displayed page.

    My idea for the procedure:

    1. the customer comes to the reception and asks for a monthly ticket to borrow.

    2. the employee creates a data record using a tracker
    2. a Tracker 1 Selection of a free monthly ticket
    2. b Tracker 2 Selection of an authorized patient.
    Documentation of the time of borrowing.
    Documentation of the employee who borrows.

    3. the borrower clicks on "borrow ticket" in the kiosk system.
    4. the kiosk system now displays the collected data from step 2
    5. a drawing field is displayed for signing.
    6. the borrower confirms with "OK".
    7. the picture of the signature is sent to the tracker, or the tracker imports the picture of the signature

    Whether the kiosk system runs under a Raspberry or not is irrelevant. Prerequisite is a browser and a touchscreen, e.g. also a smartphone...

    I will implement a test page on my internet server and publish the links here. But it will take two weeks.

    Hi Klaus,

    Sounds like a very interesting project, I would definitely be interested in learning about how the 'journey' goes.

    I have a bit of farming background and some Tiki experience (though my Pi's are mostly still in boxes) so am contributing to a page for Farming Automation https://dev.tiki.org/Farming-Automation which is under the general IoT page https://dev.tiki.org/Internet-of-Things

    It would be great if you feel like collaborating and sharing your experiences - you could create a page, maybe call it Raspberry Pi projects or whatever you think is appropriate and connect it to the IoT page.

    Good luck,
    Mike

    Hello,
    did not have time to install a Test-Tiki, but found a solution for a signature input:


    How can this be done with the Tiki now?

    Background: I see a great potential for a software solution based on Tiki for quality and especially knowledge management for rehabilitation facilities and clinics. The software used for patient administration (HIS Hospital Information System) is inflexible, closed and offers no interfaces. QM is often still implemented with text files (Word). It is like the dark middle ages...

    The most important part is to pick the lib How to pick a software library

    Please see some options at: Signature (Section: Hand-written_drawn_signature_for_agreements)

    Once we pick, we can integrate easily and leverage this new feature 😊

    Thanks!

    Added https://gitlab.com/valterj/signature_pad to the list (MIT)
    Integrate this (or similar) to a tracker field (saving in a file gallery) would be great. ?
