Dimitar: I disagree that this is the only class of users:

another class - novice users / UROPs

* no previous LCM experience assumed

* working on a specific subsistem.

* mid-to-low programming skills

etc...

another class - visiting student

* some robotics experience but no previous LCM experience.

* needs to quickly understand how a specific project is working by looking at the LCM info

As a general rule I think we should try to assume as little as possible about the user's abilities (even for grad students :) )

feedback from users for GR1

User Analysis

Andy:

I think we have a single user class -- researchers in robotcs

Characteristics of user class:

• Mid-20s
• Well educated
• Highly motivated for research tasks
• Familiar with the specifics of their hardware and software
• Expert computer users
  • Linux based systems (most users)
    • Medium to heavy command line use
  • Understand networking at a medium level
    • Know what an IP address is
    • May or may not know the difference between TCP, UDP, broadcast, etc
• Willing to dedicate large amounts of time to understanding robot dynamics, interactions, controls
• Too busy to dedicate large amounts of time to learning new interfaces unless use is immediately obvious
• Care a lot about delay on their systems
• Have used LCM before, likely have used lcm-spy (previous desktop interface)
• Work in 5-20 person labs
  • Willing and able to ask for help
  • Environment noise level varies
    • One user operates a wind tunnel
    • Another user operates a very loud air compressor
