The input peripherals aren’t anymore the only way to transmit intentions to the machine, being now possible to do it with our own body. The number of devices that allow gestural interaction, without the need of intermediate peripherals, are increasing, mainly in the area of video games. This tendency raises several questions that need to be investigated in the area of person-machine interaction. The simplistic approach of transferring interaction concepts from the classic paradigm WIMP, based on the traditional input devices, mouse and keyboard, quickly leads to unexpectedproblems. The characteristics of an interface conceived to a gestural interaction were there isn’t any kind of contact with an input device won’t suit with the paradigm of the last 40 years. So we’re in conditions to exploit how the gestural interaction can contribute to minimize the classic paradigm issues. In this work the field of gestural interaction, with and without voice, will be analyzed. Through the use of applications, it’s intended to lead various studies of virtual objects manipulation based on computational vision. The objects manipulation is done with two kinds of interactions, gestural and voice, that may emerge integrated our not. It’s intended to analyze if the gestural interaction is appealing to the users for some kind of applications and actions, while for other types, gestural may not be the preferred interaction modality
