6 17 Sep 2016 Application Remove Notification Module - Boarding Gate Updates and belt no. API were not available and creating or sourcing for an API would be too time-consuming Accept Accept & Low Priority Closed
6 20 Sep 2016 Application Update project version to be compatible with iOS 10. To future proof the app so that future development on the app will be easier to integrate. This will reduce the risk of libraries becoming outdated in the future. Accept Accept & High Priority Closed
6 23 Sep 2016 Application Formally removed seat-booking function, update current booking function, SMS function There are no APIs are available and implementing it ourselves would be very time-consuming.

Technical Overview

Technical Complexity

Tech-Comp.jpg

3DS Authentication Send API request to Tocco’s payment URL Response returned will consist of bank’s ACS URL Start phone server Send POST Request to ACS URL with URL of phone server ACS URL returned will consist of page for OTP. OTP HTML will be sent as response which will be rendered on the app User will receive OTP from bank which he will enter. After entering OTP, a POST request will be sent from the bank’s server to which the phone server will receive indicating the payment was a success Once the payment succeeds, the server will be shut down.

Tech-Comp--1.jpg

User submits price watch and the details of price watched is stored on Firebase. NodeJS Server runs an hourly check on pricing by retrieving prices via Tocco’s API If lowest price for flight is within 10% of the max pricing or less, NodeJS Server sends a notification user’s phone via Firebase

Testing User test plan Every sprint, the QA team will conduct an integration and regression testing to ensure that the app is still working fine after the new implementations and to look for more corner cases in order to make the app more stable. Quality Assurance
Design & Research Use case This is the use case diagram for our iOS app and management dashboard. Our diagram can be viewed here Use Case
Market Study We conducted a market study of the popular travels apps in the market to see what are the unique selling points and mandatory features that these apps share to help validate our client's claim that there is a gap in the market for speech-to-text booking and a recommendation engine. Our research can be viewed here: Market Study

Results
Demographic of Users
Total no. of participants: 26
We tested a majority of non-IS students to understand their needs and view on the usability of our application as we have previously in UT
2 tested mostly IS students.
All of the participants have not used our application prior to the Usability Test.

Male Female
14 12


School Count Percentage
Information Systems 9 35%
Business 8 31%
Accountancy 6 23%
Social Science 3 12%

Overall:
Participants rated the different functions’ usability and the design of the many pages of the application. The results are as following:

Screen Usability Design No. of Errors
Price Watch Alerts 8.92 8.73
Home/Speech 8.77 8.92
Flight Search 9.27 9.04
Add Passengers 9.19 9.19 1
My Trips 9.04 8.54
My Recommendation 7.38 8.88
Login 8.78 1
Filter & Sort 8.54 1
Create Price Watch 8.04
Average 8.66 8.88


Speech-to-Query

Unsuccessful Successful
No. of users 6 20
% of users 23% 77%

Users thought of a leisure trip in mind and the details of the trip before testing out the speech function. The unsuccessful cases were due to inaccuracy of the speech-to-text/natural language processing technology in understanding the participant’s speech.

Speech-to-Query

Function No. of Testers No. of Errors Avg. Time Taken(s) Max Time Taken(s) Min Time Taken(s) Comments
Speech-to-Query 20 0 37.8 130 5 Quite cool, can detect the dates and speech.

Surprisingly easy!!!! Caught all my words even when I said “wanna” I tried to speak in proper English with clear pronunciation.

Type Query 26 0 42.8 80 7


Recommended Travel Destinations

Recommendation No. of users % of users
"Drag" item for Top Destination is unresponsive 13 50%
Unclear of how to interact with "Drag" item for Top Destination 8 31%


Other Comments:

Naming does not convey a recommendation
Not clear which image refers to which country at a quick glance


Create Price Watch

Create Price Watch No. of users % of users
Find it impossible or difficult to navigate to Price Watch 10 38%
Difficulty using slider for adjusting price target 6 23%
Very useful functionality that should be explained more clearly to users and 'advertised' more within the app (e.g. weeks, clear mention that input is a target price as anyone may think of PW as a notification when price drops.) 7 27%

Other Comments:

Colour of the top bar could be bolder
Price watch very empty. Fading background and not blue background, like a photos or pictures; Blue and grey line
Should add a confirmation message for the user that acknowledges that the app has accepted the price watch target. Next price watch setting should be set to the current price watch setting.


Filter & Sort Flight Search

Filter & Sort No. of users % of users
"Reset" filter is confusing; "Done" would be more easily interpreted than a "Back" icon 8 31%
Flight filter should have the airline names arranged in alphabetical order 2 8%
Design of the times filter feels too compact 2 8%
Size of 'pop-out' stretch over screen edges 2 8%
Slider is hard to use because the numbers 12am, 12pm, 12am are not helpful and the right side may be blocked due to "fat fingers" 2 8%

Other Comments:

Sort could be a dropdown instead of pop out.
Maybe show summary of filters on the main page.
Sorting can be in ascending or descending order.

OVERALL COMMENTS:

Sort could be a dropdown instead of pop out.
Maybe show summary of filters on the main page.
"Definitely will use the app"
"Useful, speech function is easy to use. Not sure if will use to purchase, will prefer a bigger screen for security/peace of mind."
"Interesting app, feels like Skyscanner"
"Very user friendly, but can improve about the clarity of the inputs."
"Functional & useful travel app. Would be an app I use for future travels"
"Overall I thought it was a very sleek app which I would use in the future. Design wise, maybe more pictures can be added. Function wise, it’s quite amazing. "
"Features are available but difficult to use."
"For some functions, the UI is too plain or too much text. Make use of more icons."
"Useful app, easy and convenient to use, able to filter to the exact flight appropriate for my trip – can manipulate all the details! "
"Interesting as it has a few additional features to make planning of trips better (did not know of price watch before). Concerned over how much info may be tracked"


Key findings:
Need to improve on

  1. Top Destinations to be ‘dragged’ more easily/clearer hint on use
  2. Filter navigation bar buttons should be consistent and clear
  3. Creating Price Watch should be easier to navigate to, have clear explanations and better way to input values
