The aim is to present results of a usability test of a prototype of a
context-based personalized hybridmedia service for delivering product-specific
information to consumers. We recorded participants’ eye movements when they
used the service either with a camera phone or with the web browser of a PC.
The participants’ task was to search for product-specific information from the
food product database and test calculators by using both a PC and mobile user
interface. Eye movements were measured by a head-mounted eye tracking system.
Even though the completion of the tasks took longer when the participants
used the mobile phone than when they used the PC, they could complete the
tasks successfully with both interfaces. Provided that the barcode tag was not
very small, taking pictures from the barcodes with a mobile phone was quite
easy. Overall, the use of the service via the mobile phone provides a quite
good alternative for the PC.
