Redraw the following dialogue box
retaining the existing functionality but putting the components
into a more effective design based on the principles discussed
in class. Note which principles you are using and how they
affect your redesign.
Question 2:
In the recent
project you designed a hand-held interface for a restaurant where
the patrons used a PDA to look over the menu, order, pay the bill
etc. Another option which may become possible in a few years is
allow the patrons to order through the table itself. With the
price of LCD and plasma panels decreasing, and large touch screens
generally available, these tables could be easily implemented
today. In this question please design the user interface for an
ordering system at a restaurant where the patrons use such a touch
screen table to view the menu, place orders, pay the bill etc. You
can assume you have a rectangular table with seats for 4 to 6
people and a table-top resolution of 2560 X 2048. Obviously you
don't want the plates or the silverware to accidentally trigger
the menus. And you need to deal with the single display being able
to support omni-directional viewing where ‘up’ is to the center of
the display and ‘down’ is toward the edges of the table; we will
assume that you have a widget set that can be arbitrarily
oriented. As in the sketch phase of the second project you should
show how the user(s) would interact with this table effectively
through a series of drawings and explanatory text which show off
all of the functions that you are providing. Think before you
draw; and its probably a good idea to do some quick rough sketches
before deciding on the one to flesh out and turn in. Only turn in
your sketches based on your final design of the system.
CS 422 – Fall 2002 Final Exam
Question:
Throughout the term you have been
designing and refining an interface for ordering food from a
restaurant on a PDA. In class we have also done an exercise in
refining the desktop interface to a video conferencing system.
For the final exam you will be combining these two, creating the
interface for a hand-held version of that same video
conferencing system.
The PDA is
very similar in form to what you have been using … 320 x 240
screen, scroll wheel on the upper left side, power button (now
on top), 4 main function buttons, a 4-way joystick, a
microphone, and a wireless networking card built in. The user
also has the usual ability to tap / click and drag on the screen
with the stylus. Now we add on a small colour camera mounted to
the top of the unit. We will assume that this camera can grab
and transmit a video stream of 240x240 pixels at 10 frames per
second. We will also assume that the PDA can receive 3 other
video streams through the wireless card at the same time and of
the same resolution.
The
videoconferencing system has basically the same functionality as
the desktop system you modified and refined in class. It should
be able to handle audio and video connections between 4 users
(including the local user.) Some of the people in the conference
may be at desktop computers and others using this new PDA
version. It should make it easy for people to set up these
conferences and adapt to changing conditions while the
conference is going on. Here screen real-estate is at much more
of a premium, which will have large affects on the design. You
should definitely make use of the various good ideas presented
in class in the various designs.
I have
provided sheets of paper with a correctly sized PDA and screen
that you can use to draw and explain your design. Feel free to
draw expanded versions of the screen, but be careful to be
realistic in the amount of detail you can pack into the 320x240
screen. Note that the exam is two hours long and you have dealt
with both the hardware and software before, so I am expecting
you to come up with a very complete design for this, as well as
good explanations for your design choices.
