General Description

• Project started around 1995
• Formerly known as Classroom 2000
• Automation of Capture and Access in a classroom
  environment
• Suite of programs to take notes of live
  lectures with little or no human intervention

4
Traditional Ways of Learning

• Memory
• Pen and Paper
• Tape Recorders
• Electronic Texts

5
Motivation and Objective

• Generative vs repetitive learning
• Free the user to synthesize while at the same
  time provide ways to repeat information
• Learning activities broken down into several
  streams with a common attribute time.
• Ubiquity, Transparency, Mobility and use over time

6
Motivation and Objectives

• Automated capture in the classroom can provide a
  detailed record of a lecture in the form of
  autonomously generated media enhanced notes that
  students will regularly access in their review
  and study of college lectures

7
Requirements of Capture and Access

• Convenient, Constant Access to Captured materials
• Everyday use
• Unobtrusive
• Ability to evolve the system
• Ability to evaluate the impact

8
Research Scheme

• Pre-production
• Live capture
• Post Production
• Access

Discussion of Results

• Students
• Eclass does not encourage skipping
• Students take fewer more summary style notes
• Students want personalized notes
• Privacy is not a worry but needs to be addressed
• Performance is not impacted
• Eclass is perceived as a legitimate learning tool
• Eclass has authentic use

Key Learnings

• There should be a motivating application
• The system built should address some notion of
  scale
• System should be subjected to real and everyday
  use
• Prototype ubiquitous computing solutions rapidly
• The structure of an evolving system matters
• Cost is not a limiting factor
• Capture is meaningless without access

16
Other Lessons

• Create an environment in which users can be
  developers
• We cannot build everything in a research
  environment
• Understand the difference between a demonstration
  prototype and an evaluation prototype
• It is valuable to simulate automation with manual
  effort but only for a short period of time

17
DUMMBO

• Informal meeting and discussions
• Automatic, context based capture and access
