    People who do not know a place of interest have problems on their first visit, causing them a bad experience. In this context, a person can look for alternatives to get to know these places virtually, before getting to know them physically. However, most of the options are not a reflection of reality. Basically limiting them to see the exteriors of a place. In this sense, a virtual interaction platform is proposed where the user can control an avatar with hand gestures, to get to know a place virtually before getting to know it physically. In this way you can improve your experience on the first visit to the places that are of interest to you. In this project, a 3D model of the Huachi campus of the Technical University of Ambato (UTA) is proposed. This platform works with two integrated systems, running on the same computer. The first system consists of a hand gesture recognition model. This system uses the Leap Motion Controller sensor to capture the gestures made by the user. These data are sent to the model. This is in charge of processing them using a KNN classifier, to predict a label that represents the gesture. Subsequently, the predicted label is sent through the TCP/IP communication protocol, with the local IP address of the computer where the platform is running. The second system receives the label and interprets it as an instruction that the avatar must comply with by performing an action within its virtual environment. The platform was tested by 15 people. A group of 5 people who do know the UTA, and another group of 10 people who do not know the UTA, giving priority to people who do not know the UTA. The model was tested by the researcher, performing 20 repetitions for each gesture. Finding that, with kn=5 and frames=400, an accuracy percentage of 100% is obtained in the Open Hand gesture, 85% in the Close Hand gesture, 65% in the Wave In gesture, 95% in the Wave Out gesture, and 10% on the Pinch gesture. These gestures are used for the interaction of the avatar with the virtual world. However, the action corresponding to the Pinch gesture is limited, due to its low percentage of accuracy
