Abstract
Denne afhandling undersøger, hvordan navigationen på medietablets kan beriges ved at tilføje direkte, positionsuafhængige multifinger-gestus, så brugerens handlinger oversættes mere direkte til enhedsfunktioner. Apple iPad blev valgt som case på grund af platformens modenhed. Først blev der gennemført en teknologisk analyse af iPad’en for at afdække mulige begrænsninger for implementering af multifinger-gestus, efterfulgt af en psykologisk analyse af brugerrelaterede forhold, som dannede grundlag for designet af en eksperimentel app. I et forsøg med 20 deltagere blev multifinger-interaktion sammenlignet med traditionel enkelttryk-interaktion i en række navigationsopgaver. Resultaterne viste, at multifinger-metoden overordnet set ikke overgik enkelttryk. Dog forstyrrede femfingergesten forsøget i en sådan grad, at udeladelse af denne gestus indikerede signifikant bedre resultater til fordel for multifinger-metoden. Studiet peger derfor på et potentiale for multifinger-gestus i tablet-navigation, hvis gestusdesign og antal fingre udvælges og afstemmes omhyggeligt.
This thesis investigates how navigation on media tablets can be enriched by adding direct, position-independent multi-finger gestures that translate users’ actions more directly into device functions. The Apple iPad was selected as the case platform due to its maturity. A technological analysis examined feasibility and constraints for implementing multi-finger gestures, followed by a psychological analysis of user aspects to inform the design of an experimental application. In an experiment with 20 participants, multi-finger interaction was compared with traditional single-touch interaction across navigation tasks. Results showed that the multi-finger method did not outperform single touch overall. However, the five-finger gesture disrupted the experiment to such a degree that excluding it indicated significantly better results in favor of the multi-finger method. The study thus points to potential benefits of multi-finger gestures for tablet navigation, provided the gestures—especially the number of fingers—are carefully designed and selected.
