Abstract

This experiment was an analysis of different annotation methods for photos. The three annotation methods used were direct annotation (drag and drop), click and type, and textbox. This experiment evaluated performance time to annotate photos and subjective preference for the three methods. The experiment was performed on 48 subjects. Our hypothesis was that direct annotation and textbox would have the fastest time while click and type coming in the last place. In terms of subjective preference, we hypothesized that direct annotation would receive the highest subjective preference, with click and type in the second place and textbox in the last place. The result, however, showed that textbox had the fastest performance time, although not significantly faster than direct annotation and click and type. For the result of subjective preference, direct annotation came in the first place; this suggests that our hypothesis was in right direction.
