The Explanation of the Assignment...
Assessment task details and instructions
The goal is to provide a design solution for a limited selection
of
features of a restaurant waiter/waitress ordering system based on
a
touchscreen device running MS Windows. Your design must offer
the
lowest barrier to entry flow using the device’s touch interface so
that
the users can quickly enter, review and place orders.
All user interactions should be carried out via the touchscreen
device
(no physical buttons available). You may use text, images, symbols
and animations where
necessary to convey the meaning and input requirements of each
screen.
You need to produce a design solution for the software user
interface with respect to users
performing the functions outlined below and to keep within the
physical constraints imposed by
the device and operating system (OS). Your design must be produced
and justified using
background research, task analysis, and the PHEA methodology (see
lecture notes) for error
tolerant design as presented in the lectures. As the human factors
and UX practitioner you
must evaluate the available technology and design brief in terms of
error vulnerability and
devise the most appropriate solutions in order to provide the
highest possible tolerance to user
error.
The Technology that need to be used on the
Assignment...
Your system should be designed to operate on an 8” multi-touch
screen enabled device that can
be used in portrait or landscape orientations. The device will be
running Windows 10 OS with a
1280 x 1024 pixel resolution display (landscape). All interaction
must be carried out via the
screen, however, you may devise any kind of on-screen control that
you feel is appropriate to
the typical usage scenario which you are investigating. For
prototype testing there are touch
screens available in our computer laboratories.
Functions:

You are to design the interface with the following
functions in mind:

1) Creating a new customer account for a particular table number by
adding a customer
nickname and table number.
2) Adding food items to the account (from a selection of starters,
mains, deserts) including
additional special notes for the chef.
3) Modifying a food order
4) Placing the final order (for each course)
5) Recalling an order for modification or issuing the bill.

The prototype design solution should start from an initial app main
menu showing the major
tasks available. The prototype design solution must include error
dialog (messages, screens)
where appropriate. You do not need to design or implement any other
features of the device
other than the functions detailed above. You do not need to
implement a database or a real
working system, but a prototype working system that behaves like a
real system so it will
provide a realistic experience for your test users (see below).
The Questions that I need help with...
1) Problem research
Design description and references to appropriate design and
usability theory beyond Task and
Error Analysis. E.g. journal and conference papers, theory books,
case studies. (minimum 2 pages).
2) Hierarchical Task Analysis diagram or structured
task list covering an interaction design for
the above functions. (minimum 1.5 pages)
3) Error Analysis table detailing predicted error
modes and proposed design suggestions relating
to the task analysis solutions. (minimum 2 pages)
4) Diagrams of your prototype screen designs
sketches including any features and messages
taken from your error table and other design research next to
corresponding screenshots of your
a functional prototype demonstrating the sophistication of your
application (Proposed designs that do not relate
to the error table and have no other form of design rationale will
receive no marks for part 4.)
