Program Animation (1/2)

• Program Animation stands for those applications
  that show the execution of a program by means of
  a multimedia display.
• They can be used in any phase of the development
  cycle of a program.
• Jeliot family is designed to aid students to
  learn programming

Program Animation (2/2)

• Jeliot familys key feature is its automated
  process
• Eliot and Jeliot I were semi-automatic.Users had
  many possibilities to prepare the visualization
• Jeliot 2000 and Jeliot 3 are fully automatic.
  Users focus on programming and forget about
  visualization details. A single visualization
  model is applied.

Jeliot family and history

• 1993 Eliots development began at the University
  of Helsinki
• 1997 Jeliot I was released
• 2000 Jeliot 2000 was implemented at the Weizmann
  Institute of Science in Israel
• 2003 Jeliot 3 is released, developed by the
  University of Joensuu in Finland

Evolution (1/2)

• Eliot was platform dependent, and thus it evolved
  into Jeliot I, that presented a web interface. It
  only needed a Java-capable web browser to run.
• Eliot and Jeliot I were found to be hard to grasp
  by novice users. Moreover, it only animated data
  types.

Evolution(2/2)

• Jeliot 2000 handled the problems of usabilility
  and provided an application for novices that
  helped them to learn the basics of programming.
• Jeliot 3 is the generalization of Jeliot 2000. It
  broadens its support to object oriented features
  and improves its usability, adding features that
  makes it easier to use at lectures.

Using Jeliot 3

• As lecture material
• Follow-up assigments
• In interactive laboratory sessions
• Virtual courses

Jeliot 3 and Woven Stories (1/3)

• Future research towards Collaborative Program
  Visualization
• Woven Stories is a co-authoring tool in which
  multiple users can read and write the same
  document (composed by nodes). Changes are
  instantaneously shown to all active users.

Jeliot 3 and Woven Stories(2/3)

• This new system will let
• users to visualize programs
• send these visualizations to other users
• comment other users programs and visualizations
• chat with other users
• A learning community can be built up from this
  innovative tool

Conclusions

• The development has taken long and been fruitful
• Jeliot can help learning and can be used in many
  different kinds of situations
• We invite new users and developers to join our
  efforts
