Is there a reason Daniel used his bare hand to dial the DHD?

I noticed it after rewatching this episode, that at the end, Daniel deliberately removes his glove to dial the DHD, then begins to put it back on as the episode ends. Was there a need for direct contact with either the symbols, or more likely, the dome in the center? Was this perhaps something that was scrapped early on to allow episodes where a DHD is in area where such a limitation would hinder things (A place with no atmosphere for example)?
