Meeting notes

The meeting notes will follow the structure

<DD-Mon-YYYY> (use heading 4 for readability)

and be on this page in plain text (with some formatting):

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 :) )

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
