As a favour, I've been asked for my opinion and possible solution for a usability problem.
Imagine a website that gives a calendar grid of prices for each day and you can view a month at a time.
To change the month, there is a horizontal slider above the calendar grid, but when I watched someone use the page they commented that they wanted to change to a later month but missed the slider completely.
(you can view the page in action here: http://bit.ly/bObHbu)
Pop up bubble
One suggestion I thought of was an overlay styled like a speech bubble that points to the slider and reads: "Did you know... you can view another month by dragging the date slider" which would have a close button, or close automatically when clicking outside the bubble.
I feel like I've seen this used before, maybe to show new features of a website after a redesign in the past (Yahoo! or BBC?) but now I can't find any examples, does any one have any examples of this, or other ways of pointing out functionality?
Don't use a slider
Another idea is not to use a slider at all - buttons or tabs could be used to allow people to change the month that is currently viewed, as could a drop-down list with months as options. The slider was chosen because it was though it would be more fun to use, and make the page feel more interactive rather than completing a form - again I'd love to hear anyones thoughts around this
