GREEN TEA

• WIRELESS APPLICATION
• FOR EVERYDAY
• LIFE

HCI? And that is

• HCI, or Human-Computer Interaction, is a
  discipline concerned with the design, evaluation
  and implementation of interactive computing
  systems for human use.

• Both male and female

  able.

HEURISTICS

• MINIMALIST APPROACH
• USABILITY
• DOCUMENTATION
• ERROR PREVENTION
• NAVIGATION (ABSENT)

5
MINIMALIST APPROACH

• For the design of our website, we used
  calming/easy on the eyes colors, minimal
  graphics, and an easy to read font.
• In doing so, we wanted to be sure that nothing
  would take away from the users attention other
  than that which is their focus (the site/app).

6
USE OF THE STANDARDS

• When designing our application, we kept in mind
  that our consumers will include busy people,
  those who do not have time to learn an elaborate
  wireless application or complex website.
• By use of standard navigation techniques and a
  familiar to all form (for the data entry and
  submission) these potential problems are
  eliminated.

7
USABILITY

• Because Green Tea is an application that is meant
  to be used not only on the web, but also on cell
  phones, it was our utmost priority to design an
  application that will be user friendly.
• With that in mind, the User ID is created by
  using the users existing (phone) number. Aside
  from being easy to remember, it is also numeric,
  and thus, rather easy to enter on a phone.

8
USABILTY

• Paper Prototyping for our website
• turned out to be an almost complete waste of
  time, as our site is lacking most of the things
  that are the basis of all/any usability issues.
  Theres no navigation, little scrolling if any,
  and our use of error prevention is so solid that
  it negates the necessity of any help options.

9
USABILTY (continued)

• In the time we did spend testing our paper
  prototypes, the first two users actually
  questioned the need for testing on such a simple
  site. While their questions were admirable, they
  were completely without merit, as any good Human
  Computer Interaction expert will tell you, it is
  imperative you

10
USABILTY (continued)

• Know thy user
• And the first rule of Fight Club is
• Thou are not thy user!

11
DOCUMENTATION

• For those wireless companies who will be putting
  bids out on our application, it is important in
  that respect that the application be easy to
  maintain on top of being well documented.

12
DOCUMENTATION

• Our application has a rather large deal of
  documentation. Wireless service providers will
  receive documentation packages including Dfd
  diagram, well commented Source Code, and a Data
  Dictionary

13
ERROR PREVENTION

• As with any site, it is important to exercise a
  measure of error prevention. This will help
  users avoid potentially critical problems.
• Green Teas site is written with JavaScript code
  that will warn users if there is an error of some
  sort in their registration form.

14
NAVIGATION

• In the spirit of keeping our project as simple as
  the idea for which it stands, the Green Tea
  website is as stripped down as it can be. I can
  think of very few sites that make use effectively
  of omitting a sophisticated navigation scheme,
  but ours does just that. Leaving out all the
  add-ons and attention diverting possibilities has
  left the Green Tea site in extremely simple
  condition.

15
GROUPING TECHNIQUE

• In order to prevent the confusion in lists
  created by the user, our application allows them
  (users) to create lists with names unique to that
  particular group.

16
GROUPING TECHNIQUE

• So, for a list of movies that a user would like
  to see, the name can be Movie, where as for a
  list of groceries to buy, the name can be
  Shopping. That will allow the user to keep
  things organized and ready to access as needed.
