This document discusses several projects created to link physical and electronic scrum boards using QR codes. It includes a card printer app to generate tickets with QR codes, an Android app to interact with a JIRA board by scanning QR codes, and a Python app using a Raspberry Pi camera to detect ticket movements on a physical board and update the corresponding electronic ticket. Future plans include further developing the Android and augmented reality prototypes to integrate physical and digital workflows.

Why does this project exist?
•It seemed like a good idea at the time
•Wanted to play with computer vision using a cheap system
•Scrum seems to be harder than it could be
•Physical or electronic board?
•Better visibility without more admin

QR Codes – The glue
•Needed some way to tie the different systems together
•Looked at a lot of options:
•NFC
•RFID
•Vuforia frame markers
•Rejected all these for similar reasons:
•Cost (Monetary and effort / time)
•Complexity
•QR Codes are simple to generate and to read
•We can simply encode the ticket ID. With other systems we need some way to link to ID.

So, what did we do?
•Tool to print out tickets with QR codes
•Android app for easier interaction with a JIRA board
•Python app to monitor a physical board and update a JIRA board
•A bonus prototype (Watch this space!)

Card Printer
•Simple Java app to print QR coded tickets
•Currently imports from CSV but can be done using REST
•PDF Layout using iText

Android app
•Easy way to link physical board to electronic ticket using QR codes
•Focus on only developing functions you’d use regularly on a mobile phone
•View state of the sprint (Burndown, Open, in progress closed tickets)
•View details of specific tickets
•Assign a ticket to somebody
•View and add comments on a ticket
•View attachments on a ticket
•Change status of a ticket (We didn’t get to this one)

Android app

Python app
•Designed to have only one simple job
•When a physical ticket moves, update the electronic version
•Achieved by running on a Raspberry Pi with Camera module (Total cost: R1485)
•OpenCV to detect movement
•REST services to update ticket

Augmented Reality
•Ran out of time, so only prototyped
•Done using Unity and Vuforia
•Augmented view of project board
•Plan is to overlay info on tickets. More tickets less detail

Where do we go from here?
•Android project is useful – Continue development
•Add useful functionality, but be careful to not overdo it
•Integrate augmented functionality
•Card printer – Useful as is
•Fetch tickets using REST to make it even simpler
•Raspberry Pi solution just not viable yet
•Might work with a pan & tilt mount
•Probably worth playing with using this as a build server
•Can integrate with physical devices to show build status (Lava lamps anybody?)
