First, I'd like to offer my sincere apologies for being unable to fully understand your question. Thus, I'd try to make my answer as broad as I can. If you mean "reality contact" as making contact with real people in real time in exhibitions, it is very useful both for advertising and public relations purposes. Remember, advertising is different from public relations, though. Public relations is for companies and organisations while advertising is for products and services.
