  • 8. What I Learned #1
    A captioning vendor can be a better solution than alternatives in some cases.
  • 9. What I Learned #2
    Providing captions in one area can lead to unexpected benefits in another area
    Undergraduate Admissions now has captions on almost all of their online video content
  • 10. Administrative Video
  • 11. Commencement Ceremonies
    At Purdue, available on:
    Local access cable TV
    Simultaneous webcast
    What did I start with?
    Fear of the unknown
    My fears were unfounded
  • 12. What I Learned #3
    New collaborations to provide captions can come from unexpected places.
  • 13. Academic video
  • 14. Echo 360
    Lecture capture system
    Business relationship with AST allows automated submission of each lecture recording
    Waited for an opportunity where captioning was needed
  • 15. Echo 360 (cont.)
    A distance education student needed captions in 2 classes
    Collaboration with the IT unit in charge of Echo 360 was critical
    Effort required to set up the “automatic” submission
    In 2 or 3 business days, the caption file was returned & integrated into the recorded lecture
    Student found the captions very helpful
  • 16. Echo 360 Captions
  • 17. What I Learned #4
    Ask questions of vendors and look for built-in collaborations to provide captioning.

  • 19. Intercollegiate Athletics
    Ohio State case
    Desire to caption the words of the PA announcer, during the game and during breaks
    Purdue Athletics explored potential for captions on scoreboards
    Not possible at this time
    Could captions be provided directly to mobile devices in sports venues?
  • 20. Captions Using Twitter
    Challenging to keep posts below 140 character limit
    Student testing showed that posts took about a minute to show up
    Too long for game captioning
  • 21. Captions Using CoveritLive
    CoveritLive is a web based live blogging tool (www.coveritlive.com)
    No limit on number of characters in post
    Posts show up in a few seconds on most web-enabled mobile devices
    Blackberry issues
    Season ended before student testing could be conducted in Spring 2010
  • 22. Captions & CoveritLive (cont.)
    Athletic Dept very supportive of this project
    Purchased 3 iPod Touches to loan to students
    Testing with students will begin soon
    Blackberry issues continue
