Abstract
Different game technologies as the Microsoft Kinect and the Nintendo Wii Remote has been remarkable for the growth of motion gaming. Even so, competition between players seems to be integrated in most video games in the video game industry. Yet, collaboration features can carry new game experiences that can interest some players. This thesis discusses some distinct Kinect gestural interaction and relates them to if they can enhance the collaboration feeling between players. The controls chosen for each interaction are simple and were tested in a casual collaboration game called Geometry Friends. From the different controls, four different types of interaction were chosen to be tested: Hand interaction, Full-Body interaction, Tangible interaction and Collaboration gestures interaction. Furthermore, a Wii motion control interaction was properly compared within many different aspects. Natural gestures, collaboration sense, gesture recognition, gesture exhaustion and space issues are some of the aspects compared between all interaction tested. The tests revealed that Geometry Friends can achieve true collaboration sense and this sense vary with an interaction change, yet no direct correlation was found between natural/playability factors and the collaboration sense of the players. All this contributed to conclude that more tutorials and difficulty changes should be evaluated carefully when changing the game interaction, especially when changing to a gestural interaction.
