To avoid the occlusion problem and the fat finger problem while manipulating mobile touch devices, researchers in HCI community have explored the area of mobile camera-based interaction which utilizes camera input instead of touch input. For mobile camera-based cursor manipulation, selection mechanisms may have an effect on users' pointing performance, and therefore worthy of study. In this research, we conducted a user study to explore how selection mechanisms influenced users' performance in mobile camera-based cursor manipulation and users' preferences. The quantitative results indicate that the users' performances of using two selection mechanisms (the button-based selection and tapping-based selection) are similar to each other from a statistical point of view. However, subjective feedback from the participants shows that the tapping-based selection is believed to be more comfortable and easy to use.
