Survey Framework on client

[MKV21]

API to define surveys for the user which will be displayed in the app. Features required:

• single choice (+ slider)
• multiple choice
• free text
• range (slider)

What do you mean by slider for single choice? oO

[MKV21]

I guess a slider is always single choice, you are right, as there is an own bullet point for sliders this is no extra feature ;)

Single choice would be radio buttons, multiple choice checkboxes. Free text and slider are special.

[maoswald]

Added survey pages and another range question with min and max values. Protocol should be finished if there are no other features required?! Protocol for survey

From maoswald in the wiki

Survey

Every survey could have multiple pages with multiple questions. There are 5 different types of questions:

• 1 - single choice
• 2 - multiple choice
• 3 - open question
• 4 - range (percent)
• 5 - range (min max)

This is the protocol structure.

server protocol

This is the protocol sent to the client.
