Why did he catch my eye and smile at me when he saw me staring at him?

I was staring at my crush to get his attention and to let him know I was interested in him when he was speaking to a group.
When I was staring at him his eyes quickly looked over at me for a couple of seconds and he smiled

What does this mean?
