Abstrakt
Calibration of a projector and a tracking device is an essential step for interaction with projected content using gestures. We propose a novel technique for calibration of a data projector and a Leap Motion sensor. Using the proposed approach, users can calibrate the system by touching few points on the screen plane and in the space above it. No printed patterns, reflective markers, or additional tools are needed. The calibration process involves two steps. In the first step, we collect finger positions which we then use in the second step to find the calibration matrix and projector position. We compared the accuracy and precision of the proposed method to the accuracy and precision of a capacitive touchscreen in a touch based interaction task. During the evaluation we measured the Euclidean distance between the displayed and touched points. The best average distance for our method was 1.23 mm which is comparable to 0.79 mm for touch screen. The experiments demonstrate that the technique is suitable for an interaction with user interface elements designed in the usual way.
