Pagination vs. Scrolling

Have there been any studies on when it is most appropriate to switch to
paging a

list versus scrolling?

In other words, if I have a list of 20 items, I might use a simple
scrolling mechanism

to move through the list. But if the list grows to 2000, I might use a
paging mechanism

(with 20 item windows).

What number of items (if any) is the breaking point to make the switch?
Can anyone

share some common practices?

Best regards,

UI Requirements for Mobile Devices

Hi all,

I am looking for some guidance on where to find some good UI Requirments
for Mobile Devices (PDA, phones, etc.). Specifically looking for
recommended font sizes (in pixels) on a 240 x 320 screen, minimum button
sizes, etc. I've found some stuff from ANSI and some military specs,
but a lot of that stuff is very outdated.

Question about display of date select functionality

I need some help.

I am working on an application that requires the user to select a
start and stop date. This function is similar to a travel sites'
Depart Date and Return Date fields. The main difference is that we
want to constrain the dates that can be select to only those dates
that the user receives service.

I immediately wanted a calendar display because it provides context
to service periods and days of the week.

I'd add "human factors" to that list as well. And I have sometimes been amazed
by how little some usability practitioners know about human factors.

recording interviews

hi guys! I've been a lurker, but i figured i'd chime in on this.
i did a LOT of research on recording phone interviews. and i finally
got it figured out.

In order to figure this out, i tried the following: skype, jk audio
recording device, paid conference call services.

And here's the best:

1. I used a free conference calling service called
freeconferencecalls.com, but they are now basement ventures. still a
great service and FREE.

Is the IXDA a well-kept secret? (was:InterestingArticle About Usability as a Career in New York Times.)

I'm a member of UPA as well. My perception is that UPA is actually less
focused than IxDA.

>From their site:

"The UPA supports those who promote and advance the development of
usable products, reaching out to people who act as advocates for
usability and the user experience. Members come from across the broad
family of disciplines that create the user experience. We invite you to
network in our community."

An interaction designer easily fits this mission statement.

Clearly the UPA and IxDA are wildly different demographics. I look at
the UPA conference speakers list (http://tinyurl.com/28owdb), and not
only do I not personally know any of the speakers, I only *recognize*
three names on the entire list! Everyone else is someone I've never
heard of.

So why the compartmentalization?
