Efficiency of Kinect in Gestural Numerical Input: A Comparative Study

This project explores the efficiency of Kinect using gestural numerical input methods. The hypothesis is that "connect-the-dots" input will outperform other gesture-based inputs. The study involved exploring design space ideas like sliders, "Swype" style, and keypad design, with 16 participants over 2 days. Results show that 8 users preferred keypad, 4 preferred Kinect buttons, and 4 preferred Kinect sliders. Quantitative data on completion time and accuracy, as well as qualitative feedback via Likert surveys and comments, were collected.
