I'm working on a touchscreen UI application at the moment, and as many
of you know, such interfaces present pretty interesting challenges.
This project is especially interesting in its complexity; it deals with
pretty vertical domain knowledge and its users need extremely flexible
and freeform methods of interaction with the kiosk...tons of buttons,
which certainly creates rather interesting issues of screen real estate
at 1024x768. ;-)
Naturally, this had made me very aware of touchscreen UI's I've used
recently. The four touchscreens I've interacted with the most, and what
stands out about each of them, are:
- ATM's: Extremely simple and clear through limited choices and
familiar transaction patterns ( do (foo) from X to Y, in (bar) dollars)
- Home Depot Self-Checkout Kiosks: Simple interaction design (scan
item, see subtotal, say 'finished,' see total, pay), abysmal error
handling (they still require 1-3 people to solve problems per set of
four kiosks, depending on customer volume).
- Airline Ticketless Self-Checkin Kiosks: Very narrow user goal (give
me my freakin' ticket!); card-swiping hardware alleviates manual data
- The Toyota Prius (2004-2005 models): Simple (four main menu items),
but having to drill down for common controls (fan speed, seek within a
CD track) is a dangerous distraction...and a combination of hard- and
soft-keys, between the touchscreen, the driver's wheel, and the main
dashboard, requires multiple loci of attention while driving.
Does anyone have a touchscreen experience that stands out as being
uncommonly complex, satisfying, or bewildering? And how you might have
emulated or improved upon it if you were designing one yourself?
