QR Code for Poll

1 Initial Problem

This feature depends on Content Tab for Poll.

When working with Polls in a live setting (presentations, lectures, etc.), it is cumbersome to share around links as text, and having people typing them in manually on their mobile devices.

2 Conceptual Summary

The Content Tab of Polls (see Content Tab for Poll) should optionally contain a QR code of the static link to the Poll.

3 User Interface Modifications

3.1 List of Affected Views

3.2 User Interface Details

The Content Tab of Polls (see Content Tab for Poll) should contain an optional block with a QR code of the static link to the Poll.

To toggle this block on and off, a checkbox is offered in the settings. Default is off.

3.3 New User Interface Concepts

A new KS component 'QR Code' is required. It should take a string as input, and return the corresponding QR code as an image.

3.4 Accessibility Implications

No foreseeable accessibility implications.

4 Additional Information

4.1 Involved Authorities

If this request is related to multiple components, please list both authorities for all related components.

4.2 Technical Aspects

QR codes should be generated server side, e.g. using endroid/qr-code. A variety of similar libraries is available, so there is no risk of getting locked into a dependency.

The QR code KS component should offer options for different error correction levels and sizes for the generated code. Reasonable values of those parameters depend on the expected length of the string, and of the context of its usage (QR codes that are printed on paper benefit more from a higher error correction than those shown on a screen, for example).

4.3 Privacy

No privacy implications.

4.4 Security

No foreseeable security implications.
