ContextContextAs a team we chose to evaluate Jet2 and Ryanair

Wide range of user experience will give us a variation of perspective for evaluation

Eye TrackingEye Tracking

Why eye tracking is appropriate for our project

It tests interface usability

Allows us to understand how information is processed

by a user, when looking at visual information.

It provides us with evidence to undertake our

evaluation.

Because our tasks were mainly search based, eye

tracking was able to provide us with very accurate

data.

The Three TasksThe Three Tasks

1. Find the telephone number of the head office /

customer service desk

2. Locating the site-map / A-Z index of website content

3. Continue the booking process up until the website

requests your personal details, to find flights from

Leeds/Bradford airport to Malaga airport on the 2nd

January 2011, and a returning flight on 8th January

2011 for a 40 year-old couple with a 15 year-old

daughter.

Reasons for choosing the Reasons for choosing the taskstasks The third task given was cognitive as it tested the

potential usability failure of Jet2.

The reason being is, it stipulates that an adult is

classed as a person over 12 (in small grey writing).

Where as Ryanair classes an adult as a person over 16.

We thought it would be a good usability check and a

possible test of the ‘Error prevention’ evaluation

criteria.

Booking a flight for someone who is classed as an adult

on one sites (Jet2) and a child on the other (Ryanair)

What did the eye tracking What did the eye tracking data show?data show? Jet 2 scores higher of the two sites with an

average total of 125.8, where as Ryanair has an

overall lower score of 94.2

Both show appalling results with the aesthetics.

Participants were not always clear on what was

happening with each performed action, when

using Ryanair.

Also contact details scored miserably for Ryanair.
