Thread OT: Lookups with Touchscreens
Wed, Jan 11 2006 9:04 PMPermanent Link

"Adam H."
Hi Guys,

I've been asked to make my first touchscreen application, which should be a
bit of fun. The main screen (where data will be entered) will consist of
around 12 fields - 1/2 been lookups, and half been 'direct entry'.

I haven't had any experience in the past with touchscreens, but I was
planning on using DBLookupCombo's for the lookup data, and then when the
user presses the other fields (direct input), it would bring up on the
screen a keypad, or a keyboard, depending on whether the data is numberic,
or alpha.

I was wondering if their were any traps to look out for, with touchscreens,
or if anyone could see anything wrong with the above approach. (Especially
relating to lookup fields).

Does anyone have any suggestions / tips?

Thanks & Regards

Adam.

Adam,

I started one once for someone, but then abandoned the
project for other reasons unrelated to the touch screen. The
one thing I remember is to use large controls with a decent
amount of spacing. Some people have meatier hands than
others and, depending on where it is to be used, some people
might also be wearing work gloves. Also, I've seen touch
screens where the click cooridinates are out of alignment
with the image so having some room for error is nice.

Otherwise, as I recall its pretty simple. Just works the
same as if a mouse clicked on the control.

Really not much to know.  Your finger on the screen becomes your
pointing device so just make sure your controls are big enough to do
that.

I agree with other guys, it's pretty much the same as
a mouse. When you touch the screen with your right hand
it's like right-mouse button and the left hand is your
left-mouse button.

I don't even want to guess what you use for your scroll button in the middle ;p
