abstract = {In urology, conveying information about pathology and treatment to 

the patient often proves to be dicult because the concerned organs are not 

visible. In order to improve the situation, this thesis aims to develop a tool 

for simple knowledge transfer between physician and patient. By combining an 

augmented reality (AR) application on a tablet computer with a 3D print of a 

prostate, details about pathologies and possible treatments are conveyed in a 

simple to understand manner. The application supports two di↵erent interaction 

paradigms - touch based and with virtual buttons that are printed on paper - that are being compared in a user study (n=11). 

The study aimed at evaluating the usability and the intuitive use. Completion of the given tasks was done faster on the display ( : 120s, = 33s) vs. the virtual buttons ( : 253s, = 82s). The touch-display paradigm scored 4.4 out 

of 5 in the QUESI questionnaire (2.95 for VB) and 86 out of 105 (vs. 74 VB) in 

the ISONORM questionnaire. One-tailed, paired t-tests were conducted one the mean scores per questionnaire on a per-user with ↵= 0.05. The resulting p-values 

0.0045 for ISONORM and 0.003 for QUESI both show a statistically significant 

di↵erence. The results show that the display based paradigm is less error prone 

and, due to a more familiar interaction scheme, the preferred solution amongst 

participants.},
