CS 452/652 Fall 2019 - Lecture 24

Demo Preparation

Basics

• participants: demo group, instructor, teaching assistant
• 30 minutes, roughly 2 parts of 15 minutes max
• no requirement to fill the 15 minutes alloted time!

General Advice

• you are in control → stay in control!
  • get back in control, if necessary: harrumph, set up next demo, speak louder!
• compe prepared
• don't leave dead air
• two students: one presenter, one operator
  • switch roles at some point
• for each step of the demo:
  • before: explain what is going to happen and why
  • during: point out what to pay attention to
  • after: provide more details, if necessary
• take into account knowledge of audience
  • general knowledge and experience with subject matter
  • no detailed knowledge about your particular project, difficulties, trade-offs, etc.

Part 1 - scripted

• plan what you are going to do and who will do it
  • know which parts of your program working and only show working parts
  • explain what does not work
  • if necessary, show partial functionality using different programs
  • think about timing and specific phrases you want to use
  • despite your best preparations, things might still go wrong...
• prepare to explain:
  • what does a particular part of the demo show?
  • where will the train(s) go? why?
  • what does train motion show about your speed calibration?
  • what is the operator doing at the terminal? show us!
  • what parts of the demo are done automatically vs. manually?
• increase chances for success
  • dry-run entire demo
  • keep copy of working executable

Part 2 - unscripted

• we might ask questions, such as
  • can you do this with another train?
  • can you do this on the other track?
  • can we fake sensor triggers?
  • can the train go to this or that location?
