Ripple: An Open Source Mobile Audience Response System
- 1. RIPPLE An Open Source Personal Response System to Add Enhanced Interactivity through a Mobile Web Application William Myers Asst. Director Interactive Media Group University of Oregon Libraries
- 3. What is Ripple? Ripple is an interactive audience response system that allows presenters to survey audience members in real time communication through their mobile devices.
- 4. The Challenge? • Enhance instruction by allowing an audience to interact with presenter • Limit financial cost to faculty and students • System must have custom functionality to send Open Sound Control (OSC) messages.
- 5. What makes Ripple unique? • Web application • User Centered Design • Designed for mobile devices • Open Source • Extendable
- 7. User Centered Design If it is not great for the individuals using the application, then it needs to change!
- 8. Lessons We Learned… Presenters want options… Core Question types: True / False Multiple Choice Open Response Numeric Variable Slider Word Cloud
- 9. Lessons We Learned… • Chat is not always a good thing. • Just because the system can, doesn’t mean it should.
- 10. Lessons We Learned… Less is more.
- 11. Lessons We Learned… Usability trumps aesthetics and technology especially for technology sake.
- 12. Mobile Reference: 1 http://www.digby.com/mobile- 2 http://www.localytics.com/blog/2013/mobile-statistics/statistics/ • 56% of American adults are now smartphone owners. 1 • 31% of adults own a tablet device. 2
- 13. Mobile Reference: 2 http://www.localytics.com/blog/2013/mobile-statistics/statistics/ • 44% of cell phone users have slept with their cell phone by their side so they didn’t miss a notification. 2 • The average age for a person’s first cell phone is now 13. 2
- 14. Ripple & Mobile • Responsive Design • Tested on multiple mobile devices including iPhone, iPad, and Nexus 7 • Compatible and tested on Firefox, Chrome, Safari, and IE 9
- 15. See It In Action… http://youtu.be/fA_N7SempXw
- 16. Let Try it out! http://goo.gl/m8z6Ky
- 18. Open Source • Project on Github: https://github.com/uoregon-libraries/ripple • GPLv3 License • Free to the World, free to use
- 19. Why Open Source? • Community of Support • Community Development • Ripple Website http://ripple-core.uoregon.edu/ • Issues Forum https://github.com/uoregon- libraries/ripple/issues • Contribute and help others
- 20. Extendable • Ripple accepts plugins • Customize it to fit your needs • Ripple plugin page: http://ripple- core.uoregon.edu/plugins/ • Plugin API: http://ripple- core.uoregon.edu/api/latest/
- 21. FAQ Is there a record of student responses? – Yes, each session generates a report that can be accessed by the presenter. The report can also be exported as a csv file.
- 22. FAQ What if I have a student that doesn’t have a device? – Small Group or Pair Students – Have multiple browsers on a single computer – Use cheap mobile device: iTouch, Kindle, old smartphone with only wireless
- 23. FAQ If I let students use their mobile devices in class, won’t it be a distraction? – Maybe, depending on how you allow students to use the device. Isn’t this the same problem as having a laptop in front of them?
- 24. FAQ Can Ripple use 3G/4G? Yes, since Ripple is just a website, as long as the computer running Ripple has an external ip, any cell data plan can be used, or, better yet, just use wi-fi (no data charges apply)!

- Web App:Nothing to download Nothing to installUser CenteredSoftware was built wholly focused on the audience member and the presenterIterative testing between prototyping, focus/usability testing, redesignTook the time to do it rightMobileFrom the inception, Ripple was designed for different devicesWorks well and most everythingOpen SourceAll code is always availableNever vendor lock-inExtendableRipple can take plugins to extend it functionality
- This clip will give you just a quick preview of how Ripple works.Left side is Presenter ScreenRight side is Student Device
- Concept GenerationPrototypeDevelopment IterationsFocus Group TestingUsability TestingRedesignPut the design aside, put the technology/programming aside and focus on the user!
- Ripple becomes unique because of the types of questions and how easily they can be added toRight question for the right job!
- Technically easyWas a distractionDid not add value to the classroom environment
- Some things worked great on desktop but failed miserably for mobile. Replaced with text input and keypad
- If the student can’t get their answer in easily then it is not worth having
- The most profound stat:100 Level Human PhysClass of 207 students97% had a device that would work with RippleLets harness that power and bring education to where the students are.

- Community SupportWe do not have resource to support everyone so it will take a communityCommunity DevelopmentAdoption exponentially increase functionalitySimilar to WP or DrupalContributeWe have seen how other open source products have matured – Wordpress / Drupal We hope to benefit from what others can do with it
- For higher ed classes: Most 100 level class , hordes of facebook & twitter surfers
