Understanding user gestures for manipulating 3D objects from touchscreen inputs

We conducted a user study to better understand how non-technical users interact with a 3D object from touchscreen inputs. The experiment has been conducted while users manipulated a 3D cube with three points of view for rotations, scaling and translations (RST). Sixteen users participated and 432 gestures were analyzed. To classify data, we introduce a taxonomy for 3D manipulation gestures with touchscreens. Then, we identify a set of strategies employed by users to realize the proposed cube transformations. Our findings suggest that each participant uses several strategies with a predominant one. Finally, we propose some guidelines to help designers in the creation of more user friendly tools.
