The interaction with medical software<br />

during interventions challenges physicians<br />

due to the limited space and<br />

the necessary sterility. Current input<br />

modalities such as touch screen control<br />

present a direct, natural interaction which<br />

addresses usability aspects but do not<br />

consider these challenges. A promising<br />

input modality is freehand gesture<br />

interaction, which allows sterile input and<br />

a possibly larger interaction space. This<br />

work compares gesture and touch input<br />

regarding task duration to perform typical<br />

intervention tasks and intuitiveness. A<br />

user study with ten medical students<br />

shows mostly significantly better results<br />

for touch screen interaction. Despite the<br />

advantages of freehand gestures, it is<br />

debatable whether these can compensate<br />

the better efficiency and usability<br />

results of touch screen interaction in the<br />

operating room.<br />
