Is there any all-purpose opposite for "in person"?

I'm looking for a term or single word that can be used as the opposite of "in person" in situations we might be involved in a given activity without our direct (physical) presence, like:

• Taking online courses instead of taking part in classes

  "_____ courses" vs "in-person courses"

• Having a videoconference instead of meeting someone in person

  "_____ meeting" vs "in-person meeting"

• Having an interview over the phone instead of a face-to-face interview

  "_____ interview" vs "in-person interview"

• Shopping online instead of going to the market

  "_____ shopping" vs "in-person shopping"

I have found "absentee" like in "absentee vote" but I don't think it can be used as the opposite of "in person".

Is there really any opposite for "in person" that can be used generally, so that I can fill all those blanks with that?

Remote.

Harvard Law School website has a section on Remote Interviewing which may be Telephone Interviews or Skype/Videoconference Interviews.

Quoting dictionary.cambridge.org:

remote adjective (DISTANT)

Having a remote interview.

I've never seen it used in this context, but I think it would be a good use of "virtual". Wikipedia defines "virtual" among other meanings as "Operating by computer or in cyberspace; not physically present".

On-line... Yes, today on-line refers mainly to experiences over the internet, and if you look it up in a dictionary (at least the ones I just looked in) the definition is singularly linked to such experiences. However I own several old warranty cards and manuals from before the invent of said internet referring to on-line help being available at some phone no.

So clearly the dictionaries have it wrong. On-line means "over the phone", and thus by extension also over the internet (as the internet initially was transmitted over the phone line)
