Interfaces To perform the task were used 3 different interfaces: two interfaces without physical contact, being the Kinect® for Windows from Microsoft, composed of a traditional RGB camera and an infrared depth sensor (IR) and LMC®, characterized as a small motion sensor that demonstrated robustness to measure the movements of the hand and fingers. The interface with physical contact, the touchscreen, was the computer screen itself, where individuals touched the screen in order to burst the bubbles, performing the task. It is noteworthy that the touchscreen is a sensitive interface, employed through pressure, created in order to interact with digital information, found in a majority of modern consumer electronics, mainly computers, tablets and mobile phones.
