What information should the speaker transmit during the title slide of a conference presentation? Any standard presentation starts with an opening slide which displays the title of the presentation, name of the speaker and collaborators, affiliation and some attractive image.  

Before any conference presentation the chair of the session usually tells the audience the name of the speaker and the title of the presentation. I have seen the following scenarios happen:  


Speaker completely ignores the title slide and goes straight into the rest of presentation (assumes that after the chair gave the introduction there is no need to repeat his name/title)
Speaker gives an "extended version of the information". Example: "My name is X and today I will be talking about [insert more verbose version of the title]. I work in University U and collaborate with Y and Z". This can already serve as an introduction or an overview about what will be addressed during the presentation. (Should there be an overview slide for this instead?)


So, how important is the first slide of a presentation? What information should the speaker transmit in it? How much time should the speaker spend with it?

Does it matter if we are talking about a conference presentation vs invited presentation at an institute?

EDIT: Based on comments - I am aware that this question may be opinion-based but, as Dirk stated in the comments, the answer should be "based on how the different options are perceived by the audience", what impact the beginning of the presentation has in the audience and how it sets the rest of the presentation. Also, I should point that I am still in the beginning of my academic's career, and I still don't have a name that everyone will recognize straight away and immediately know what I do.
I've heard the following advice: When the people in the audience see somebody they don't know, they'll be asking themselves "What kind of guy is this?" for at least some minutes. I guess anybody does this, mainly subconscious. This implies that it is harder to convey technical information in the first minutes, since people work subconsciously to find out who you are and what they should think of you. 

So when I start my presentation I always have at least three sentences that are not technical. This can be "Thanks to the chair for the (nice, warm) introduction.", "Thanks to the organizers (I prefer to give names here) for having me here (at this nice place/great session).", "My name is...  and I will speak about...  (collaboration with...)...". There could also be a sentence about the meeting in general or one that relates the talk to previous ones at the conference. 

This may cost you one or two minutes which you loose for your precious technical content, but I think it's worth it if at least a few people in the audience don't know you already. If you don't spend these few sentences, the chance is higher that you'll loose these people from the very beginning. Anyway, conferences are (in my understanding) as much about people as they are about research. If I go home from a conference and didn't have had nice conversations and met a few new people, it wasn't a good meeting.
