                 Introduction
• Smart phones have introduced great easiness to
  our daily life by mobile applications. One of the
  easinesses provided is buying flight tickets via
  mobile phones. However poor consideration of
  end-users in development phase leads to
  underutilization of such facility, thus decreasing
  potential profit of companies.

               Introduction
Airline ticket reservation is in top 5 most
purchased online service[1] :




                                              3
               Introduction
• Smart phone use is increasing and mobile
  commerce is expected to be future’s
  shopping style.
• In near future, more people are expected to
  buy flight tickets using their mobile.
• Challenge arises at that point : Many
  companies -> many customers. The one
  pleases the customer would win the
  competition of mobile commerce (M-
  Commerce).

User’s Experience




                    5
   Experience and Preference
• User’s experience affects user’s
  preference of using that application again.
• When user perceives a mobile application
  easy to use, enjoy it to use and efficient in
  terms of provided services, customer’s
  loyalty is gained [2].
• Therefore, usability should be analyzed
  from the point of users.

                                                  6
                Objective
• The objective of the study is to identify
  usability problems for mobile flight booking
  applications on touch-screen phones, and
  suggest solutions.
• Main expectations of users are presented
  from HCI perspective and discussed
  through a case study.
                                              7
                Related Works
• Some research works have been done on the usability
  challenges of travel webpage and mobile commercial
  applications. Psychological background of user’s
  perception towards products are investigated. Guidelines
  for better application usability are suggested for different
  mobile platforms.

• However, there is little research about usability
  challenges faced in touch screen phones, since it is a
                                                             8

General User Experience Goals
• Utility: usefulness, reliability
• Usability: ease of use, efficiency,
  accessibility
• Social value: connecting people,
  identification
• Enjoyment: pleasure , stimulation


                                        10
             Methodology
• In order to understand social and personal
  phenomena in the context, a qualitative
  approach is adopted in which we
  conducted interviews with twenty(20)
  people at two phases and collected
  answers from questionnaires to increase
  the accuracy of results.

                                           11
 How was the study conducted?
• 20 people aged between 18-40 randomly
 selected.
• Interviews were conducted:
• Users were asked to complete the task of buying
 a flight ticket to any destination of their choice.
 Their ticket buying processes were closely
 observed.
• Notes and questionnaire results were analyzed.
 R esearch findings related to flight travel, usability
 concerns of mobile applications, and user
                                                       12
 satisfaction criteria were utilized as guidelines.
 How was the               study conducted?
• Other market applications that offer mobile flight booking
  service were also explored for benchmarking.

• Problem areas were detected and solutions were
  extracted from previous research findings and
  benchmarking analysis.

• Second interview was conducted to obtain user’s
  reaction towards the prototype that was built to eliminate
  problems that had been found in the first interview.
                                                          13
                      Results
What are the usability challenges that       mobile   flight
                booking applications face?

4) Naming of menus and
         sections
             Guesses about the
             meaning of
             “Mobile ticket” :
               • Movie ticket
               • Concert ticket
               • Flight ticket
               • SIM card, etc..



                                   19
 4) Naming of menus and sections

• Users expect “interaction”.
• Need for a “talking” system.
• Instead of “Flight planning”, choose
  – “Plan your flight”,
• Instead of “destination”,
  – “Where do you want to go?”


                                         20

           To be Done Things …
• Functions for disabled people, speech search,
  speech-to-text facilities, geo-locations services,
  personalized flight booking assistance have
  been omitted of this study due to its large
  complexity that will not fall under single work.
• In fact, the entire process took considerable time
  from collecting data to analyzing the data, then
  designing appropriate graphical interfaces for
  practical implementation.
                                                       47
