Detailed Description

Ripple is an interactive audience response system that allows presenters to survey an audience in real time. Audience members receive and answer questions sent by the presenter on their internet/network connected device. Answers are compiled in real time on the presenter’s screen for immediate feedback and discussion.

Audience response session questions can either be created prior or in real time to solicit impromptu feedback.

Ripple is installed with six core question types: True/False, Multiple Choice, Open Response, Slider, Numeric, and Word Cloud; however, it also accepts plugins to extend it functionality.

Benefit to XSCE

What is the benefit to the platform? If this is a major capability update, what has changed? If this is a new feature, what capabilities does it bring? Why will XSCE become a better platform or project because of this feature?

Make sure to note here as well if this feature has been requested by a specific deployment, or if it has emerged from a bug report.

XSCE powered classrooms will become more interactive, and the system can be used by XO and non XO hardware, users just need a web browser.

Teachers can also design tests to be run using the tool, as the answers are saved and can be downloaded in csv format.


What work do the developers have to accomplish to complete the feature in time for release? Is it a large change affecting many parts of the distribution or is it a very isolated change? What are those changes?

Some changes to current ripple are:

- Identify XO users using xo moodle cooke
- Internacionalization / Translation
- Change session name generation, as 6 alphanumeric chars may be too much for kids to type.

UI Design

Does the feature have a direct impact on the work flow, or does it need a UI? Link here mockups, or add detailed descriptions.

How To Test

Testing notes go here - Log in with admin default user / password, and create a session

User Experience

If this feature is noticeable by its target audience, how will their experiences change as a result? Describe what they will see or notice.


What other packages (RPMs) depend on this package? Are there changes outside the developers' control on which completion of this feature depends? In other words, does your feature depend on completion of another feature owned by someone else or that you would need to coordinate, which might cause you to be unable to finish on time? Other upstream projects like Python?

  • openssl-devel
  • gcc+c++
  • mongodb-server
  • nodejs 0.8.25

Contingency Plan

If you cannot complete your feature by the final development freeze, what is the backup plan? This might be as simple as "None necessary, revert to previous release behaviour." Or it might not. If your feature is not completed in time, we want to assure others that other parts of Sugar will not be in jeopardy.


Is there upstream documentation on this feature, or notes you have written yourself? Has this topic been discussed in the mailing list or during a meeting? Link to that material here so other interested developers can get involved.

Release Notes

The XSCE Release Notes inform end-users about what is new in the release. The release notes also help users know how to deal with platform changes such as ABIs/APIs, configuration or data file formats, or upgrade concerns. If there are any such changes involved in this feature, indicate them here. You can also link to upstream documentation if it satisfies this need. This information forms the basis of the release notes edited by the release team and shipped with the release.
