| dc.description.abstract | Tangible User Interfaces and Touch interfaces have become
increasingly popular as ways of providing direct coupling between the user
and the interface, but how suited are these input methods for ship
navigation? This thesis investigates the possible differences in workload,
user experience and visual gaze when using tangible and touch controls on a
tabletop display for the purpose of ship navigation. An experimental study
using within-subject design was conducted. 21 experienced navigators
participated by navigating a ship in a simulator environment, using tangible
and touch controls. To empirically test the two controls, three methods of
data collection were implemented. 1) NASA R-TLX measuring subjective
workload. 2) User Experience Questionnaire (UEQ) measuring User
Quality, User Design and Attractiveness. 3) Video recordings to establish
where the participants were looking (Visual Gaze) during navigation. The
data was analyzed as paired t-tests. Findings indicate that the tangible
controls are more suitable for ship navigation than the touch controls.
Workload was perceived as higher with the touch controls. User experience
was rated higher with the use of tangible controls, and it was found that the
participants spent far more time looking at the interface during navigation
with touch control compared to tangible control, which required less visual
attention. | nb_NO |
