Error Analysis for Tablet User Interface Transfers Based on Operational Knowledge Interference

摘要

Operational errors were collected and analyzed with regard to the use of different tablet UIs. The effects of previous operational knowledge upon the use of new devices were clarified through user experiments in which forty subjects participated. A comparison was made of three different types of tablet UIs that were equipped with three different operating systems: iOS 5, Windows 8 (release preview), and Windows 7. The results showed the user's dependence upon previous operational knowledge when using a new tablet PC. This dependency was demonstrated both in the ratio of the users' accurate operation, and in their process of exploring an unknown operation.
